      OMAP1: pass LCD config with omapfb_set_lcd_config() · ddba6c7f
      由 Tomi Valkeinen 提交于 
      LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.

This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.

      omap: drop __initdata tags from static struct platform_device declarations · 07ad6ab3
      由 Janusz Krzysztofik 提交于 
      Pointers to statically declared platform device structures which are
registered with platform_device_register() are then used during run time
to access these structure members, for example from platform_uevent()
and much more. Therefore, these structures should never be placed inside
sections which are dropped after boot. Fix platform devices incorrectly
tagged with __initdata which happen to exist inside OMAP sub-trees.

This bug has exhibited itself on my ARM/OMAP1 based Amstrad Delta
videophone after commit 6d3163ce, "mm:
check if any page in a pageblock is reserved before marking it
MIGRATE_RESERVE", resulting in reading from several
/sys/device/platform/*/uevent files always ending up with segmentation
faults.

      omap: Set separate timer init functions to avoid cpu_is_omap tests · e74984e4
      由 Tony Lindgren 提交于 
      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.

      OMAP: GPIO: Implement GPIO as a platform device · 77640aab
      由 Varadarajan, Charulatha 提交于 
      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.

remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

      omap1: Fix DSP public peripherals support for ams-delta · b3dba0b8
      由 Janusz Krzysztofik 提交于 
      DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?)
machines as long as old dspgateway code were present in the l-o tree. For
several months it is no longer included, breaking support for McBSP1 based
audio on Amstrad Delta, for example.

This patch, derived from the old dspgateway code, corrects the problem for the
board by simply taking the DSP out of reset state, I guess. That way, things
should not break when a new dsp code is added to the tree, and the change can
be reverted then.

If there are any reports on McBSP1 or other DSP public peripherals not working
for other OMAP1 machines (I've not heard of any for now), I can prepare a more
general patch providing an extra include file with a helper function defined.

      omap1: Fix redundant UARTs pin muxing that can break other hardware support · c33da3a8
      由 Janusz Krzysztofik 提交于 
      Commit 15ac408e removed enabled_uart
and OMAP_TAG_UART. This works for mach-omap2, but causes issues on
mach-omap1 for some boards as the mach-omap1 serial.c was muxing
pins based on the enabled_uart flag for 15xx.

Fix this by muxing pins in board-*.c files for the 15xx boards for
the uart ports that had enabled_uart flag set before the commit
above.

Tested on Amsdtrad Delta only.

Note that in the future we should add support for powering down
the uarts with a timer like mach-omap2/serial.c does. Otherwise
the enabled uarts will be blocking retention-while-idle.

      ARM: OMAP: get rid of OMAP_TAG_USB, v2 · b0b5aa3f

      OMAP_TAGS should vanish soon since they're not generic arm tags.
Most of them can be converted to a platform_data or parsed
from a command line like e.g. serial tag.

For OMAP_TAG_USB we just let boards call omap_usb_init()
passing a pointer to omap_usb_config.

Patch updated by Tony for mainline, basically make
n770 and h4 compile. Also folded in a fix for OSK
