302991379c omap2plus: clockdomain: Trivial fix for build break because of clktrctrl_mask
struct clockdomain member clktrctrl_mask is available for only for OMAP2
and OMAP3 architectures. Technially it is also used only for these archs
but this breaks the build with custom OMAP4 configuration.

fe13471c4b OMAP4: hwmod data: Fix alignment and end of line in structurefields
In order to be fully aligned with the Python generator output,
change a couple of fields.

- Add tab in class structures to align attributes
- Add a comma at the end of the following line to simplify
  the generation by having always the same eol:
  ".pre_shutdown   = &omap2_wd_timer_disable,"
- Add a blank line before the first entry of the
  omap44xx_hwmods array.

b35cecf978 OMAP4: Smartreflex framework extensions
This patch extends the smartreflex framework to support
OMAP4. The changes are minor like compiling smartreflex Kconfig
option for OMAP4 also, and a couple of OMAP4 checks in
the smartreflex framework.

The change in sr_device.c where new logic has to be introduced
for reading the efuse registers is due to the fact that in OMAP4
the efuse registers are 24 bit aligned. A __raw_readl will
fail for non-32 bit aligned address and hence the 8-bit read
and shift.

        /debug/voltage/vdd_<x>/smartreflex/<parameter>

Also smartreflex n-target values are now exposed out at
	/debug/voltage/vdd_<x>/smartreflex/nvalue/<voltage>

This is a read-write interface which means user has the
flexibility to change the n-target values for any opp.

fbc319f676 OMAP3: PM: Register TWL4030 pmic info with the voltage driver.
This patch registers the TWL4030 PMIC specific informtion
with the voltage driver. Failing this patch the voltage driver
is unware of the formula to use for vsel to voltage and vice versa
conversion and lot of other PMIC dependent parameters.

This file is based on the arch/arm/plat-omap opp_twl_tpl.c file
by Paul Walmsley. The original file is replaced by this file.

fa765823a3 OMAP3: PM: Adding smartreflex class3 driver
Smartreflex Class3 implementation continuously monitors
silicon performance  and instructs the Voltage Processors
to increase or decrease the voltage.
This patch adds smartreflex class 3 driver. This driver hooks
up with the generic smartreflex driver smartreflex.c to abstract
out class specific implementations out of the generic driver.

Class3 driver is chosen as the default class driver for smartreflex.
If any other class driver needs to be implemented, the init of that
driver should be called from the board file. That way the new class driver
will over-ride the Class3 driver.

0c0a5d61ed OMAP3: PM: Adding smartreflex device file.
This patch adds support for device registration of various
smartreflex module present in the system. This patch introduces
the platform data for smartreflex devices which include
the efused n-target vaules, a parameter to indicate
whether smartreflex autocompensation needs to be
enabled on init or not. An API
omap_enable_smartreflex_on_init is provided for the
board files to enable smartreflex autocompensation during
system boot up.

984aa6dbf4 OMAP3: PM: Adding smartreflex driver support.
SmartReflex modules do adaptive voltage control for real-time
voltage adjustments. With Smartreflex the power supply voltage
can be adapted to the silicon performance(manufacturing process,
temperature induced performance, age induced performance etc).

There are differnet classes of smartreflex implementation.
	Class-0: Manufacturing Test Calibration
	Class-1: Boot-Time Software Calibration
	Class-2: Continuous Software Calibration
	Class-3: Continuous Hardware Calibration
	Class-4: Fully Integrated Power Management

OMAP3 has two smartreflex modules one associated with VDD MPU and the
other associated with VDD CORE.
This patch adds support for  smartreflex driver. The driver is designed
for Class-1 , Class-2 and Class-3 support and is  a platform driver.
Smartreflex driver can be enabled through a Kconfig option
"SmartReflex support" under "System type"->"TI OMAP implementations" menu.

Smartreflex autocompensation feature can be enabled runtime through
a debug fs option.
To enable smartreflex autocompensation feature
	echo 1 > /debug/voltage/vdd_<X>/smartreflex/autocomp
To disable smartreflex autocompensation feature
	echo 0 > /debug/voltage/vdd_<X>/smartreflex/autocomp

where X can be mpu, core , iva etc.

This patch contains code originally in linux omap pm branch.

2f34ce81b8 OMAP3: PM: Adding voltage driver support.
This patch adds voltage driver support for OMAP3. The driver
allows  configuring the voltage controller and voltage
processors during init and exports APIs to enable/disable
voltage processors, scale voltage and reset voltage.
The driver maintains the global voltage table on a per
VDD basis which contains the various voltages supported by the
VDD along with per voltage dependent data like smartreflex
efuse offset, errminlimit and voltage processor errorgain.
The driver also allows the voltage parameters dependent on the
PMIC to be passed from the PMIC file through an API.
The driver allows scaling of VDD voltages either through
"vc bypass method" or through "vp forceupdate method" the
choice being configurable through the board file.

This patch contains code originally in linux omap pm branch
smartreflex driver.  Major contributors to this driver are
Lesly A M, Rajendra Nayak, Kalle Jokiniemi, Paul Walmsley,
Nishant Menon, Kevin Hilman. The separation of PMIC parameters
into a separate structure which can be populated from
the PMIC file is based on the work of Lun Chang from Motorola
in an internal tree.

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

6d38c4b4f1 omap: rx51: Remove tvout code that plays with gpio 40
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'
