      OMAP2+: io: split omap2_init_common_hw() · 4805734b
      Paul Walmsley authored
      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

      OMAP: GPIO: Implement GPIO as a platform device · 77640aab
      Varadarajan, Charulatha authored
      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
      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
      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
      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.

      arm: remove machine_desc.io_pg_offst and .phys_io · 6451d778
      Nicolas Pitre authored
      Since we're now using addruart to establish the debug mapping, we can
      remove the io_pg_offst and phys_io members of struct machine_desc.
      The various declarations were removed using the following script:
        grep -rl MACHINE_START arch/arm | xargs \
        sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

      OMAP: control: move plat-omap/control.h to mach-omap2/control.h · 4814ced5
      Paul Walmsley authored
      Only OMAP2+ platforms have the System Control Module (SCM) IP block.
      In the past, we've kept the SCM header file in plat-omap.  This has
      led to abuse - device drivers including it; includes being added that
      create implicit dependencies on OMAP2+ builds; etc.
      In response, move the SCM headers into mach-omap2/.
      As part of this, remove the direct SCM access from the OMAP UDC
      driver.  It was clearly broken.  The UDC code needs an indepth review for
      use on OMAP2+ chips.

      OMAP3: PM: Enable wakeup from ads7846 touchscreen · 7a44ad2f
      Ranjith Lohithakshan authored
      This  patch enables the wakeup capabilities of ads7846 touchscreen driver.
      ads7846 driver can now wakeup the system from suspend on OMAP3430 EVM
      and SDP boards.
      The earlier approach of enabling wakeup on the touchscreen GPIO pin during
      board level mux init is removed. Instead the wakeup flag in
      ads7846_platform_data is enabled. Based on the flag, the ads7846 driver
      will do an enable_irq_wake which will eventually call into the OMAP GPIO
      layer and will enable the wakeup capability on the GPIO pin.

      omap2/3/4: ehci: avoid compiler error with touchbook · 6f69a181
      Felipe Balbi authored
      the early_param() call in board-omap3touchbook.c expands to:
      static const char __setup_str_early_touchbook_revision[]
      	__section(.init.rodata) _aligned(1) = tbr;
      and we have a non-const variable being added to the
      same section:
      static struct ehci_hcd_omap_platform_data ehci_pdata
      because of that, gcc generates a section type conflict
      which can (and actually should) be avoided by marking
      const every variable marked with __initconst.
      This patch fixes that for the ehci_hdc_omap_platform_data.

      OMAP3: cpuidle: Add valid field into C-state parameter passing · 709731bb
      Kalle Jokiniemi authored
      Different boards benefit differently from the available
      seven C-states for cpu idle. In most cases, only few,
      properly spaced (in terms of consumption and latency)
      C-states are required to make the power management
      optimal. Hence we need a possibility to pass which
      C-states are actually used for each board.
      So added the valid field to cpuidle_params and added
      support to 3430sdp, which uses the paramenter passing.
