Most keypad drivers make use of the <linux/input/matrix_keypad.h>
defined macros, structures and inline functions.
Convert omap-keypad driver to use those as well, as suggested by a
compile time warning, hardcoded into the OMAP <palt/keypad.h>.
Created against linux-2.6.37-rc5.
Tested on Amstrad Delta.
Compile tested with omap1_defconfig and omap2plus_defconfig shrinked to
board-h4.

Commit 60d24ee "Added video data to support tvout on rx51" added code that
tries to assign gpio 40 as OMAP DSS reset_gpio for tvout. This is wrong
since this gpio has nothing to do with OMAP DSS but it is used to control
one switch that selects is the audio jack connected to tvout or audio
circuitry.
This switch is already supported by the RX51 ASoC driver so there is no need
to control it elsewhere. Switch is contolled with ALSA control
'Jack Function' and tvout can be selected with following example:
amixer -D hw:0 set 'Jack Function' 'TV-OUT'

Commmit 60d24ee "Added video data to support tvout on rx51" broke the DSS
on RX51/N900 since it added DSS VENC support but a patch adding needed
supply is missing from tree and no framebuffers are initialized.
This patch is basically cleaned up version of original one:

commit bf56f0a6668cd (2.6.37-rc1), from Nishanth Menon attempted
to fix card detection for PandaBoard, unfortunately, the fix missed
to initialize .gpio_cd member of omap2_hsmmc_info. This results
in a default value of '0', which is a valid GPIO line.
On PandaBoard, the side effect of this is that GPIO line 0 controls
the powering TFP410 DVI chip, and without the fix DVI chip is
inadvertently powered.

Limitation i583: Self_Refresh Exit issue after OFF mode
Issue:
When device is waking up from OFF mode, then SDRC state machine sends
inappropriate sequence violating JEDEC standards.
Impact:
OMAP3630 < ES1.2 is impacted as follows depending on the platform:
CS0: for 38.4MHz as internal sysclk, DDR content seen to be stable, while
for all other sysclk frequencies, varied levels of instability
seen based on varied parameters.
CS1: impacted
This patch takes option #3 as recommended by the Silicon erratum:
Avoid core power domain transitioning to OFF mode. Power consumption
impact is expected in this case.
To do this, we route core OFF requests to RET request on the impacted
revisions of silicon.

While coming out of MPU OSWR/OFF states, L2 controller is reseted.
The reset behavior is implementation specific as per ARMv7 TRM and
hence $L2 needs to be invalidated before it's use. Since the
AUXCTRL register is also reconfigured, disable L2 cache before
invalidating it and re-enables it afterwards. This is as per
Cortex-A8 ARM documentation.
Currently this is identified as being needed on OMAP3630 as the
disable/enable is done from "public side" while, on OMAP3430, this
is done in the "secure side".

Erratum id: i608
RTA (Retention Till Access) feature is not supported and leads to device
stability issues when enabled. This impacts modules with embedded memories
on OMAP3630
Workaround is to disable RTA on boot and coming out of core off.
For disabling RTA coming out of off mode, we do this by overriding the
restore pointer for 3630 as the first point of entry before caches are
touched and is common for GP and HS devices. To disable earlier than
this could be possible by modifying the PPA for HS devices, but not for
GP devices.

Erratum i581 impacts OMAP3 platforms.
PRCM DPLL control FSM removes SDRC_IDLEREQ before DPLL3 locks causing
the DPLL not to be locked at times.
IMPORTANT:
*) This is not a complete workaround implementation as recommended
by the silicon erratum. This is a support logic for detecting lockups and
attempting to recover where possible and is known to provide stability
in multiple platforms.
*) This code is mostly important for inactive and retention. The ROM code
waits for the maximum DLL lock time when resuming from off mode. So for
off mode this code isn't really needed.
*) counters are introduced here for eventual export to userspace once the
cleanups are completed.
This should eventually get refactored as part of cleanups to sleep34xx.S

Analysis in TI kernel with ETM showed that using cache mapped flush
in kernel instead of SO mapped flush cost drops by 65% (3.39mS down
to 1.17mS) for clean_l2 which is used during sleep sequences.
Overall:
- speed up
- unfortunately there isn't a good alternative flush method today
- code reduction and less maintenance and potential bug in
unmaintained code
This also fixes the bug with the clean_l2 function usage.

omap2_common_pm_init is the API where generic system devices like
mpu, l3 etc get initialized. This has to happen really early on
during the boot and not at a later time. This is especially important
with the new opp changes as these devices need to be built before the
opp tables init happen. Today both are device initcalls and it works
just because of the order of compilation. Making this postcore_initcall
is ideal because the omap device layer init happens as a core_initcall
and typically rest of the driver/device inits are arch_initcall or
something lower.

Some bad interaction between the idle and the suspend paths has been
identified: the idle code is called during the suspend enter and exit
sequences. This could cause corruption or lock-up of resources.
The solution is to move the calls to disable_hlt at the very beginning
of the suspend sequence (ex. in omap3_pm_begin instead of
omap3_pm_prepare), and the call to enable_hlt at the very end of
the suspend sequence (ex. in omap3_pm_end instead of omap3_pm_finish).
Tested with RET and OFF on Beagle and OMAP3EVM.

This reverts commit 1ab83238740ff1e1773d5c13ecac43c60cf4aec4.
Turns out this doesn't allow for the device ids to be overridden
properly, so we need to revert the thing.

does not copy the input prompt and help text to the original
config defined in core/Kconfig. Add them now.

Fix two bugs with the port array setup.
The first bug will only show up with broken xHCI hosts with Extended
Capabilities registers that have duplicate port speed entries for the same
port. The idea with the original code was to set the port_array entry to
-1 if the duplicate port speed entry said the port was a different speed
than the original port speed entry. That would mean that later, the port
would not be exposed to the USB core. Unfortunately, I forgot a continue
statement, and the port_array entry would just be overwritten in the next
line.
The second bug would happen if there are conflicting port speed registers
(so that some entry in port_array is -1), or one of the hardware port
registers was not described in the port speed registers (so that some
entry in port_array is 0). The code that sets up the usb2_ports array
would accidentally claim those ports. That wouldn't really cause any
user-visible issues, but it is a bug.
This patch should go into the stable trees that have the port array and
USB 3.0 port disabling prevention patches.

The get_user_pages() helper can return fewer than the requested pages.
Error out in that case, and clean up the partial result.

For read operation, we have to set the argument _write_ of get_user_pages
to 1 since we will write data to pages. Also, we need to SetPageDirty before
releasing these pages.
