Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add register offsets for GPIO_IRQSTATUS_RAW_0, GPIO_IRQSTATUS_RAW_0 which are present on OMAP4+ processors. Now we can distinguish conditions applicable to OMAP4,5 and those specific to OMAP24xx and OMAP3xxx.

With HIGHMEM disabled not all of the 1GB of RAM (only ~700MB) can be accessed. Hence, enable HIGMEM to make use of the entire memory. On the boards which doesn't have more than 768 MB memory, all the memory is directly mapped in "lowmem" and highmem isn't exercised. Hence, there should be no impact by enabling HIGHMEM for boards that do not need it. Tested on OMAP4460 Panda-ES.

This is accomplished by seting the postsetup_state to enabled for all hwmods during init when runtime PM is disabled. Currently, we have a special case for WDT in that its postsetup_state is always set to disabled. This is done so that the WDT is disabled and the timer is disarmed at boot in case there is no WDT driver. This also means that when runtime PM is disabled, if a WDT driver *is* built in the kernel, the kernel will crash on the first access to the WDT hardware. We can't simply leave the WDT module enabled, because the timer is armed by default after reset. That means that if there is no WDT driver initialzed or loaded before the timer expires, the kernel will reboot. To fix this, a custom reset method is added to the watchdog class of omap_hwmod. This method will *always* disarm the timer after hwmod reset. The WDT timer then will only be rearmed when/if the driver is loaded for the WDT. With the timer disarmed by default, we no longer need a special-case for the postsetup_state of WDT during init, so it is removed. Any platforms wishing to ensure the watchdog remains armed across the entire boot boot can simply disable the reset-on-init feature of the watchdog hwmod using omap_hwmod_no_setup_reset(). Tested on 3530/Overo, 4430/Panda. NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as documented in the TRM (and what happens on OMAP3.) I noticed this because testing the HWMOD_INIT_NO_RESET feature with no driver loaded, I expected a reboot part way through the boot, but did not see a reboot. Adding some debug to read the counter, I verified that right after OCP softreset, the counter is not firing. After writing the magic start sequence, the timer starts counting. This means that the timer disarm sequence added here does not seem to be needed for 4430, but is technically the correct way to ensure the timer is disarmed, so it is left in for OMAP4.

Remove the 3505-specific checking since CK_3505 flag is not used, and treat all AM35x clocks the same. This means that the SGX clock (the only AM35x clkdev not currently flagged for 3505) will now be registered on 3505, but that is harmless. That can be cleaned up when the clkdev nodes are removed in favor of them being registered by hwmod.
