| * ARM: 7054/1: arm/tegra: Delete custom gpio_to_irq, and irq_to_gpioStephen Warren2011-08-241-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By not definining a custom gpio_to_irq, the default gpiolib version is used, allowing platform consolidation. irq_to_gpio is deprecated and in the process of being removed. Make that happen now for ARM Tegra. This also partially fixes the Tegra build; it was broken because gpio.h referred to EINVAL, which wasn't always defined when <mach/gpio.h> was included.

| * ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-121-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

| | | | | | | | | | | | | | | | | | | | Many of the gpio_to_irq implementations use the gpiolib version of this function. Provide the standard gpiolib gpio_to_irq() for everyone, but allow platforms to override it if they wish. Add the neccessary overrides for those platforms which do not use the standard definition.

* | arm/tegra: Harmony: Configure PMC for low-level interruptsStephen Warren2011-10-131-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this, the PMC continually detects an interrupt when the PMU_IRQ line is high, causing the tps6686x IRQ handler thread to hog an entire CPU. This change was originally written by Wei Ni <wni@nvidia.com> for Seaboard in the ChromeOS kernel. Long-term, this should probably be moved into some kind of PMU driver, or perhaps integrated into the GPIO/IRQ/pinmux system?

* | arm/tegra: pinmux: ioremap registersStephen Warren2011-10-133-94/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use ioremap to obtain access to registers instead of using static mappings. This reduces the number of users of the static mappings, which will eventually allow them to be removed. Note that on Tegra30, the number of register "banks" will decrease to 2, and the packing of specific bits into registers will change significantly. That's why this change adds the "*_bank" fields to the pingroup tables, rather than implementing some more hard-coded scheme. Also, completely remove the implementation of suspend/resume; Tegra doesn't yet support suspend/resume, and the implementation is complex for the general pinmux driver: * Not all registers are used within each bank, so we probably shouldn't just iterate over every register in the bank, and save/restore it, since that would mean touching undefined registers. * Registers are shared between pingroups, so we can't simply iterate over each pingroup, and save/restore the registers it uses. It'd probably be best have probe() calculate a bitmask of actually-used registers for each bank, and have suspend/resume iterate over those bitmaps. Oh, and Real Soon Now, I should be looking into converting this driver to the new pinmux/pinctrl subsystem, so I didn't want to put too much work into the current incarnation. v2: s/space/bank/ to match comments on reg_* fields in pinmux.h.

This is important because: * U-Boot statically assigns MMC device IDs based on controller ID. * U-Boot assumes that kernel MMC device ID numbering matches U-Boot numbering. * U-Boot provides a kernel cmdline option e.g. root=/dev/mmcblk0p3 based on that numbering. * The kernel dynamically assigns MMC device IDs based on enumeration order of the memory behind the host controller, rather than statically based on host controller ID like U-Boot. * By registering the SDHCI controller for the built-in eMMC first, the enumeration of the built-in eMMC is performed first, and hence eMMC gets assigned ID 0 just like U-Boot. If the SD slot is filled, it then gets assigned ID 1 just like U-Boot. * If the MMC IDs mismatch, and the system boots from SD card not eMMC, the kernel will access the eMMC instead of SD card when attempting to mount /dev/mmcblk1p3 as the root fs. If eMMC is not partitioned/formatted, the kernel will panic since the root fs can't be mounted. If eMMC is partitioned and formatted, the kernel will mount an unexpected filesystem as the root fs. This change relies on the SDHCI driver performing initial card detection synchronously during device registration. This is currently the case.

This also removes the requirement for a platform to have a mach/hardware.h. The default values for i/o and mem are 0x1000 and 0x01000000, respectively. Per Arnd Bergmann, other values are likely to be incorrect, but this commit does not try to address that issue.

(In the ChromeOS kernel, one of the I2C busses is split in two with a mux, this pushing all later busses to a higher bus number. In this case, 4 is the correct bus number for the ADT7461).

| | * ARM: 6993/1: platsmp: Allow secondary cpu hotplug with maxcpus=1Stephen Boyd2011-07-071-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an ARM system has multiple cpus in the same socket and the kernel is booted with maxcpus=1, secondary cpus are possible but not present due to how platform_smp_prepare_cpus() is called. Since most typical ARM processors don't actually support physical hotplug, initialize the present map to be equal to the possible map in generic ARM SMP code. Also, always call platform_smp_prepare_cpus() as long as max_cpus is non-zero (0 means no SMP) to allow platform code to do any SMP setup. After applying this patch it's possible to boot an ARM system with maxcpus=1 on the command line and then hotplug in secondary cpus via sysfs. This is more in line with how x86 does things.
