| * | gpio: lpc18xx: add GPIO pin interrupt controller supportVladimir Zapolskiy2018-12-072-4/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change adds support of LPC18xx/LPC43xx GPIO pin interrupt controller block within SoC GPIO controller. The new interrupt controller driver allows to configure and capture edge or level interrupts on 8 arbitrary selectedinput GPIO pins, and lift the signals to be reported as NVIC rising edge interrupts. Configuration of a particular GPIO pin to serve as interrupt and its mapping to an interrupt on NVIC is done by SCU pin controller, for more details see description of 'nxp,gpio-pin-interrupt' device tree property of a GPIO pin [1]. From LPC18xx and LPC43xx User Manuals the GPIO controller consists of the following blocks: * GPIO pin interrupt block at 0x40087000, this change adds its support, * GPIO GROUP0 interrupt block at 0x40088000, * GPIO GROUP1 interrupt block at 0x40089000, * GPIO port block at 0x400F4000, it is supported by the original driver. While all 4 sub-controller blocks have their own I/O addresses, moreover all 3 interrupt blocks are APB0 peripherals and high-speed GPIO block is an AHB slave, according to the hardware manual the GPIO controller is seen as a single block, and 4 sub-controllers have the shared reset signal RGU #28 and clock to register interface CLK_CPU_GPIO on CCU1. Likely support of two GPIO group interrupt blocks won't be added in short term, because the mechanism to mask several interrupt sources is not well defined.

| * | gpio: OF: Parse MMC-specific CD and WP propertiesLinus Walleij2018-11-291-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When retrieveing CD (card detect) and WP (write protect) GPIO handles from the device tree, make sure to assign them active low by default unless the "cd-inverted" or "wp-inverted" properties are set. These properties mean that respective signal is active HIGH since the SDHCI specification stipulates that this kind of signals should be treated as active LOW. If the twocell GPIO flag is also specified as active low, well that's nice and we will silently ignore the tautological specification. If however the GPIO line is specified as active low in the GPIO flasg cell and "cd-inverted" or "wp-inverted" is also specified, the latter takes precedence and we print a warning. The current effect on the MMC slot-gpio core are as follows: For CD GPIOs: no effect. The current code in mmc/core/host.c calls mmc_gpiod_request_cd() with the "override_active_level" argument set to true, which means that whatever the GPIO descriptor thinks about active low/high will be ignored, the core will use the MMC_CAP2_CD_ACTIVE_HIGH to keep track of this and reads the raw value from the GPIO descriptor, totally bypassing gpiolibs inversion semantics. I plan to clean this up at a later point passing the handling of inversion semantics over to gpiolib, so this patch prepares the ground for that. Fow WP GPIOs: this is probably fixing a bug, because the code in mmc/core/host.c calls mmc_gpiod_request_ro() with the "override_active_level" argument set to false, which means it will respect the inversion semantics of the gpiolib and ignore the MMC_CAP2_RO_ACTIVE_HIGH flag for everyone using this through device tree. However the code in host.c confusingly goes to great lengths setting up the MMC_CAP2_RO_ACTIVE_HIGH flag from the GPIO descriptor and by reading the "wp-inverted" property of the node. As far as I can tell this is all in vain and the inversion is broken: device trees that use "wp-inverted" do not work as intended, instead the only way to actually get inversion on a line is by setting the second cell flag to GPIO_ACTIVE_HIGH (which will be the default) or GPIO_ACTIVE_LOW if they want the proper MMC semantics. Presumably all device trees do this right but we need to parse and handle this properly.

But there's a chance the caller could immediately free the passed string(e.g., local variable). This could trigger a use after free when we use gpio label(e.g., gpiochip_unlock_as_irq(), gpiochip_is_requested()). To be on the safe side: duplicate the string with kstrdup_const() so that if an unaware user passes an address to a stack-allocated buffer, we won't get the arbitrary label.

| |/ | | | | | | | | | | | | | | | | | | | | | | With a new subsystem co-maintainer on board it is good to draw up the ongoing changes and future plans for the subsystem, i.e. what is in my head and being worked on long term. What better way is there than simply adding a TODO right in the code and send it out to the mailing list.

Additionally, once again, I am funneling changes to drivers/misc/cardreader/* and drivers/memstick/* through my MMC tree, mostly due to that we lack a maintainer for these.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using the name directly from the I2C client to name the gpio_chip, use dev_name() on the client->dev, so we get the sometimes more unique device name, as I2C has a mechanism for naming its devices explicitly in e.g. board data. This is a prerequisite for being able to reference uniquely any I2C GPIO expander defined in a board file when setting up GPIO descriptor tables.
