| * | | iio: adc: twl4030: Drop twl4030_get_madc_conversion()Sebastian Reichel2017-06-111-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop legacy twl4030_get_madc_conversion() method. It has been used by drivers to get madc data before it conversion to IIO API. There are no users in the mainline kernel anymore.

| * | | iio: adc: stm32: make per instance bus clock optionalFabrice Gasnier2017-06-111-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | STM32F4 requires one clock per ADC instance for register access. But, newer version of ADC hardware block have common bus clock for all instances (per instance driver isn't responsible for getting it). So, make it optional by default. Still, enforce it's required on STM32F4. Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

Chapter "9.5.5 Die Temperature and UID" says that the die temperature value is 282 at 25C with LSB of -1.14C. Converting CPCAP PMIC channel3 values with following seems to produce values that make sense for a PMIC die: temperature = 25000 + ((regval - 282) * 114) As we don't have any other documentation, let's assume the die temperature is unconfigured in the Motorola mapphone Linux kernel and the current temperature conversion table should be only used for the battery thermistor and not for the die temperature.

Let's fix this by initializing the ADC registers to what Android does. For getting correct values from the battery thermistor, we need to toggle the CPCAP_BIT_THERMBIAS_EN when measuring battery temperature to get correct battery temperatures. And looks like we also need to wait a little bit before reading the battery temperature as otherwise the results are inaccurate.

Fix this by passing an actual pointer, even though all we want to do is to discard the value. As a side-effect this fixes a sparse warning ("Using plain integer as NULL pointer") as reported by Paolo Cretaro.

The MFD driver has a DT node but the IIO driver does not. The IIO device registers the temperature sensor in the thermal framework using the DT node of the parent, the MFD device, so the thermal framework could match the phandle to the MFD device in the DT and the struct device used to register in the thermal framework. devm_thermal_zone_of_sensor_register was previously used to register the thermal sensor with the parent struct device of the IIO device, representing the MFD device. By doing so, we registered actually the parent in the devm routine and not the actual IIO device. This lead to the devm unregister function not being called when the IIO module driver is removed. It resulted in the thermal framework still polling the get_temp function of the IIO module while the device doesn't exist anymore, thus generated a kernel panic. Use the non-devm function instead and do the unregister manually in the remove function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The third argument of devm_request_threaded_irq() is the primary handler. It is called in hardirq context and checks whether the interrupt is relevant to the device. If the primary handler returns IRQ_WAKE_THREAD, the secondary handler (a.k.a. handler thread) is scheduled to run in process context. bcm_iproc_adc.c uses the secondary handler as the primary one and the other way around. So this patch fixes the same, along with re-naming the secondary handler and primary handler names properly. Tested on the BCM9583XX iProc SoC based boards.

| * | iio: adc: Add support for TI ADC108S102 and ADC128S102Jan Kiszka2017-05-213-0/+361
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an upstream port of an IIO driver for the TI ADC108S102 and ADC128S102. The former can be found on the Intel Galileo Gen2 and the Siemens SIMATIC IOT2000. For those boards, ACPI-based enumeration is included. Due to the lack of regulators under ACPI, we hard-code the voltage provided to the VA pin of the ADC to 5 V, the value used on Galileo and IOT2000. For DT usage, the regulator "vref-supply" provides this information. Note that DT usage has not been tested.

Currently driver uses gpiod_set_value(1) to clean reset, which depends on device tree to contain GPIO_ACTIVE_HIGH - that does not match reality. This fixes driver to use _raw version of gpiod_set_value() to enforce active-low semantics despite of what's written in device tree. Allowing device tree to override that only opens possibility for errors and does not add any value. Additionally, use _cansleep version to make things work with i2c-gpio and other sleeping gpio drivers.

This patch changes guards all BL30 functionality so it is skipped on SoCs which don't have it. Since the hardware itself doesn't know whether BL30 is available the internal meson_sar_adc_data is extended so this information can be provided per of_device_id.data inside the driver. Additionally the clocks "adc_clk" and "adc_sel" are not provided by the clock-controller itself. "adc_sel" is not available at all. "adc_clk" is provided by the SAR ADC IP block itself on Meson8b (and earlier). This is already supported by the meson_saradc driver. Finally this introduces new of_device_ids for the Meson8 and Meson8b SoCs so the driver can be wired up in the corresponding DT.

This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect.

Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters.

This new driver uses the zero length spi_transfers with the cs_change flag set and/or the non-zero delay_usecs. 1. The zero length transfer with the spi_transfer.cs_change set is required in order to select CH1. The chip select line must be brought high and low again without transfer. 2. The zero length transfer with the spi_transfer.delay_usecs > 0 is required for waiting the conversion to be complete. The conversion begins with the falling edge of the chip select. During the conversion process, SCLK is ignored. These two usages are unusual. But the spi controller drivers that use a default implementation of transfer_one_message() are likely to work. (I've tested this adc driver with spi-omap2-mcspi and spi-xilinx) On the other hand, some spi controller drivers that have their own transfer_one_message() may not work. But at least for the zero length transfer with delay_usecs > 0, I'm proposing a new testcase for the spi-loopback-test that can test whether the delay_usecs setting has taken effect.

As far as I can understand this is equal to the PMICs using SSBI transport and encompass PM8018, PM8038, PM8058, and PM8921, so this is shortly named PM8xxx. This ADC monitors a bunch of on-board voltages and the die temperature of the PMIC itself, but it can also be routed to convert a few external MPPs (multi-purpose pins). On the APQ8060 DragonBoard this feature is used to let this ADC convert an analog ALS (Ambient Light Sensor) voltage signal from a Capella CM3605 ALS into a LUX value. Developed and tested with APQ8060 DragonBoard based on Ivan's driver and Rama Krishna's patches. The SPMI VADC driver is quite different, but share enough minor functionality that I have split out to the common file in a previous patch.

Moreover, its thermal sensor does not generate interruptions, thus we only need to directly read the register storing the temperature value. The MFD used by the A10, A13 and A31, was created to avoid breaking the DT binding, but since the nodes for the ADC weren't there for the A33, it is not needed. Though the A33 does not have an internal ADC, it has a thermal sensor which shares the same registers with GPADC of the already supported SoCs and almost the same bits, for the same purpose (thermal sensor). The thermal sensor behaves exactly the same (except the presence of interrupts or not) on the different SoCs.

Good set of new drivers as well. New device support * ASPEED ADC - new driver * cpcap PMIC ADC - new driver * hid-humidity - driver for HID compatible humidity sensors. * ltc2497 ADC - new driver * mpu6050 - bring bindings up to date and add trivial support for 9250 * rockchip-saradc - update bindings to cover rk3328 * vl6180 light, proximity and time of flight sensor. - new driver Features * meson-saradc - add calibration Cleanup and minor fixes * ad5504 - constify attribute_group structure - drop casting of void * * ad7150 - replace some shifts of 1 by BIT macro usage * ad7152 - blank lines between function definitions * ad7280a - octal permissions. * ad7606 - replace use of core mlock mutex with a local lock * ad7746 - replace some shifts of 1 by BIT macro usage - function parameter alignment - drop some excessive brackets (introduced in last pull request) * ad7753 - white space cleanup * ad7754 - includes in alphabetical order and groupped appropriately. - change from missuse of internal mlock mutex to using the buffer lock to also protect values during frequency update. * ad779x - constify attribute_group structures * ad9832 - octal permissions * adis16060 - remove use of core mlock mutex in favour of adding a local _spi_write_then_read which can use the local buffer protection lock. - fix naming of above function. * adis16203 - remove locking during reads of calibbias that doesn't protect anything not protected elsewhere. * adis16209 - remove unnecessary braces in single statement if * adis16240 - remove unnecessary braces in single statement if * adt7136 - drop excess blank lines and put some in between functions. * ams-iaq - replace comma with semi colon. Not actual bug, just unusual syntax. * apds9960 - constify attribute group structure * as3935 - constify attribute group structure * bm1750 - constify attribute group structure * cros_ec - devm version of triggered buffer setup to simplify code. * exynos - drop casting of void * * hdc100x - constify attribute_group structure * hid-accel - fix wrong scale for newly introduced gravity sensor. * hts221 - drop casting of void * * hx711 - constify attribute_group structure * imx7d_adc - drop casting of void * * lm35333 - constify attribute_group structure * lsm6dsx - drop casting of void * - hold ODR configuration until enabling to avoid a race condition. * max1027 - drop casting of void * * max11100 - fix a comma where semicolon was intended (no actual bug, just odd) * max1363 - constify attribute_group structure * ms sensors - drop casting of void * * rockchip_saradc - drop casting of void * * sun4i-gpadc - fix missing dependency on THERMAL or presence of stubs (issue only introduced in pervious set) - drop casting of void * * tsl2x7x - fix wrong standard deviation calc. Note these aren't actually used for anything at the moment so bug didn't really matter. - constify attribute group structure. * vf610adc - drop casting of void * * vz89x - replace comma with semicolon. Not actual bug, just odd syntax. * zpa2326 - drop casting of void *
