Pull #1 ARM updates from Russell King:
"This one covers stuff which Arnd is waiting for me to push, as this is
shared between both our trees and probably other trees elsewhere.
Essentially, this contains:
- AMBA primecell device initializer updates - mostly shrinking the
size of the device declarations in platform code to something more
reasonable.
- Getting rid of the NO_IRQ crap from AMBA primecell stuff.
- Nicolas' idle cleanups. This in combination with the restart
cleanups from the last merge window results in a great many
mach/system.h files being deleted."
Yay: ~80 files, ~2000 lines deleted.

The chip_desc table is suboptimal. Currently it requires an entry for
every new chip type, even if it is empty. This has already been
forgotten for the ds1388. Refactor the code, so new entries are only
needed, when they chip type really needs a (non-empty) description.
Also make the table visually more appealing.

Following changes are made as part of this change:
1. As TWL RTC supports periodic interrupt, the correct event should be
RTC_PF instead of RTC_UF.
2. No need to initialize variable "events" to 0 & then OR it with the
event values. Hence fixing it.

As part of probe, before enabling RTC, RTC_CTRL register is read to check
if it is already running. If RTC is used by kernel alone, then this read
is not required. Even if RTC was enabled already by boot loader, setting
STOP_RTC bit again should not harm. Hence removed unwanted read
operation.

rtc_device_register() calls rtc-spear routines internally. These
routines call dev_get_drvdata() to get struct spear_rtc_config.
Currently, platform_set_drvdata is called after rtc device is
registered. This causes system to crash, as dev_get_drvdata returns
NULL.
For this we need to call platform_set_drvdata() before registering rtc
device. This requires further cleanup, that leads to removal of
dev_set_drvdata on rtc->dev, which was just not required at all.
Also, we change the parameter to request_irq and pass pointer to config
instead of pointer to rtc struct.
This patch brings all above changes.

* add 'struct lm3530_pwm_data' in the platform data
The pwm data is the platform specific functions which generate the pwm.
The pwm data is only valid when brightness is pwm input mode.
Functions should be implemented by the pwm driver.
pwm_set_intensity() : set duty of pwm.
pwm_get_intensity() : get current the brightness.
* brightness control by pwm
If the control mode is pwm, then brightness is changed by the duty of
pwm=. So pwm platform function should be called in lm3530_brightness_set().
* do not update brightness register when pwm input mode
In pwm input mode, brightness register is not used.
If any value is updated in this register, then the led will be off.
* when input mode is changed, set duty of pwm to 0 if unnecessary.

Only 7 bits are used for updating the brightness. (register address :
A0h) So the max_brightness property of lm3530 should be set to 127.
On initializing registers, maximum initial brightness is limited to
'max_brightness'.
Division-by-two is removed on updating the brightness. This arithmetic is
not necessary because the range of brightness is 0 ~ 127= .

The lp5521 has autonomous operation mode without external control.
Using lp5521_platform_data, various led patterns can be configurable.
For supporting this feature, new functions and device attribute are
added.
Structure of lp5521_led_pattern: 3 channels are supported - red, green
and blue. Pattern(s) of each channel and numbers of pattern(s) are
defined in the pla= tform data. Pattern data are hexa codes which
include pattern commands such like set pwm, wait, ramp up/down, branch
and so on.
Pattern mode functions:
* lp5521_clear_program_memory
Before running new led pattern, program memory should be cleared.
* lp5521_write_program_memory
Pattern data updated in the program memory via the i2c.
* lp5521_get_pattern
Get pattern from predefined in the platform data.
* lp5521_run_led_pattern
Stop current pattern or run new pattern.
Transition time is required between different operation mode.
Device attribute - 'led_pattern': To load specific led pattern, new device
attribute is added.
When the lp5521 driver is unloaded, stop current led pattern mode.
Documentation updated : description about how to define the led patterns
and example.

1) There is a NULL dereference if the tca allocation fails.
2) The call to cancel_work_sync() isn't needed because we haven't
scheduled any work.
3) The call to i2c_set_clientdata() isn't needed because the core
handles that automatically if probe() fails.
4) I added some curly braces for style reasons.

Add support for pandora (openpandora.org) backlight.
It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave. Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm
nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c
can't be used anyway.
