efe318a333 omap1: Simplify use of omap_irq_flags
Commit 03a9e51261
(omap1: Use asm_irq_flags for entry-macro.S) added support
for multi-omap builds with addition of the omap_irq_flags.

Commit 9f9605c2ed
(omap2+: Fix unused variable warning for omap_irq_base)
simplified omap2+ entry-macro.S by moving omap_irq_flags
out of entry-macro.S.

Simplify omap1 entry-macro.S in a similar way to keep the
code consistent. Based on a similar earlier patch for omap2+
by Russell King <rmk+kernel@arm.linux.org.uk>.

This is due to the recent ARM init_sched_clock() changes and the late
initialization of the counter_32k clock source.  More information here:

   http://marc.info/?l=linux-omap&m=129513468605208&w=2

Fix by initializing the counter_32k clocksource during the machine timer

eaca491f75 mtd: nand: ams-delta: drop omap_read/write, use ioremap
There is a common requirement for not using OMAP specific omap_readw() /
omap_writew() function calls in drivers/, but replace them with
readw() / writew() on ioremap()ped addresses passed from arch/ instead.

The patch implements this idea for the Amstrad Delta NAND driver. To be
able to use the modified driver, the board file is updated with the
platform device I/O resource declaration, which is passed from there.

Created and tested against linux-2.6.37-rc5, on top of recent patch
'MTD: NAND: ams-delta: convert to platform driver'.

In its current form, the driver may interfere with different hardware on
different boards if built into the kernel, hence is not suitable for

Convert it to a platform driver, that should be free from this issue.

Rename the device and driver name in order to stick
to this naming convention.

Change device name in clock nodes as well.

5de62b86d2 omap1: Fix gpio mpuio bank to work for multi-omap for 7xx/15xx/16xx
We need to divide the 15xx/16xx offset by 2 for 7xx. Use bank->stride
for that. This allows us to get rid of the duplicate defines for the
MPUIO registers.

Note that this will cause omap-keypad.c driver to not work on 7xx.
However, the right fix there is to move over to matrix_keypad instead
as suggested by Cory Maccarrone <darkstar6262@gmail.com> and
Janusz Krzysztofik <jkrzyszt@tis.icnet.pl>.

77640aabd7 OMAP: GPIO: Implement GPIO as a platform device
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.

This patches removes a config option that was used to select a FIQ
handler to be build for Amstrad Delta, as required by the on-board serio
interface driver. Not having any problem reports received since it was
introduced in 2.6.35, the FIQ handler can now be built and initialized by
default, thus reqiring no extra config option.
