Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

Helper function for updating nand platform data has been added the capability to take timing structure arguement. Usage of omap_nand_flash_init() has been replaced by modifed one, omap_nand_flash_init was doing things similar to board_nand_init except that NAND CS# were being acquired based on bootloader setting. As CS# is hardwired for a given board, acquiring gpmc CS# has been removed, and updated with the value on board. NAND CS# used in beagle board & omap3evm was found to be CS0. Thomas Weber <thomas.weber.linux@googlemail.com> reported that value of devkit8000 to be CS0. Overo board was found to be using CS0 based on u-boot, while google grep says omap3touchbook too has CS0.

As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

Otherwise omap_device_build() and omap_mux related functions can't be marked as __init when twl is build as a module. If a board is using GPIO pins or regulators configured by an external chip, such as TWL PMIC on I2C bus, the board must mark those MMC controllers as deferred. Additionally both omap_hsmmc_init() and omap_hsmmc_late_init() must be called by the board. For MMC controllers using internal GPIO pins for card detect and regulators the slots don't need to be marked deferred. In this case calling omap_hsmmc_init() is sufficient. Only mark the MMC slots using gpio_cd or gpio_wd as deferred as noted by Igor Grinberg <grinberg@compulab.co.il>. Note that this patch does not change the behaviour for board-4430sdp.c board-omap4panda.c. These boards wrongly rely on the omap_hsmmc.c init function callback to configure the PMIC GPIO interrupt lines on external chip. If the PMIC interrupt lines are not configured during init, they will fail.

This is needed for the following patches so we can initialize the rest of the hardware timers later on. As with the init_irq calls, there's no need to do cpu_is_omap calls during the timer init as we only care about the major omap generation. This means that we can initialize the sys_timer with the .timer entries alone. Note that for now we just set stubs for the various sys_timer entries that will get populated in a later patch. The following patches will also remove the omap_dm_timer_init calls and change the init for the rest of the hardware timers to happen with an arch_initcall.

Split omap2_init_common_hw() into two functions. The first, omap2_init_common_infrastructure(), initializes the hwmod code and data, the OMAP PM code, and the clock code and data. The second, omap2_init_common_devices(), handles any other early device initialization that, for whatever reason, has not been or cannot be moved to initcalls or early platform devices. This patch is required for the hwmod postsetup patch, which allows board files to change the state that hwmods should be placed into at the conclusion of the hwmod _setup() function. For example, for a board whose creators wish to ensure watchdog coverage across the entire kernel boot process, code to change the watchdog's postsetup state will be added in the board-*.c file between the omap2_init_common_infrastructure() and omap2_init_common_devices() function calls.

Implement GPIO as a platform device. GPIO APIs are used in machine_init functions. Hence it is required to complete GPIO probe before board_init. Therefore GPIO device register and driver register are implemented as postcore_initcalls. omap_gpio_init() does nothing now and this function would be removed in the next patch as it's usage is spread across most of the board files. Inorder to convert GPIO as platform device, modifications are required in clockxxxx_data.c file for OMAP1 so that device names can be used to obtain clock instead of getting clocks by name/NULL ptr. Use runtime pm APIs (pm_runtime_put*/pm_runtime_get*) for enabling or disabling the clocks, modify sysconfig settings and remove usage of clock FW APIs. Note 1: Converting GPIO driver to use runtime PM APIs is not done as a separate patch because GPIO clock names are different for various OMAPs and are different for some of the banks in the same CPU. This would need usage of cpu_is checks and bank id checks while using clock FW APIs in the gpio driver. Hence while making GPIO a platform driver framework, PM runtime APIs are used directly. Note 2: While implementing GPIO as a platform device, pm runtime APIs are used as mentioned above and modification is not done in gpio's prepare for idle/ resume after idle functions. This would be done in the next patch series and GPIO driver would be made to use dev_pm_ops instead of sysdev_class in that series only. Due to the above, the GPIO driver implicitly relies on CM_AUTOIDLE = 1 on its iclk for power management to work, since the driver never disables its iclk. This would be taken care in the next patch series (see Note 3 below). Refer to http://www.mail-archive.com/linux-omap@vger.kernel.org/msg39112.html for more details. Note 3: only pm_runtime_get_sync is called in gpio's probe() and pm_runtime_put* is never called. This is to make the implementation similar to the existing GPIO code. Another patch series would be sent to correct this. In OMAP3 and OMAP4 gpio's debounce clocks are optional clocks. They are enabled/ disabled whenever required using clock framework APIs TODO: 1. Cleanup the GPIO driver. Use function pointers and register offest pointers instead of using hardcoded values 2. Remove all cpu_is_ checks and OMAP specific macros 3. Remove usage of gpio_bank array so that only instance specific information is used in driver code 4. Rename 'method'/ avoid it's usage 5. Fix the non-wakeup gpios handling for OMAP2430, OMAP3 & OMAP4 6. Modify gpio's prepare for idle/ resume after idle functions to use runtime pm implentation.
