The resource handling in this driver was flaky: IO_ADDRESS instead of
ioremap (and no unmapping), an unneeded static resource, no central exit
path for error cases. Fix this by converting the driver to use managed
resources. Also use dev_*-messages instead of pr_* while we are here.

Ioctl WDIOC_GETBOOTSTATUS is supposed to return some information
on why the system did (re)boot recently, value WDIOF_CARDRESET
being used to indicate watchdog induced reboot.

Up to now, imx2_wdt did not provide a value here, always returning
zero to indicate normal boot.

Do evaluate the IMX Watchdog Reset Status Register and
produce WDIOF_CARDRESET with WDIOC_GETBOOTSTATUS in case
of a watchdog induced reset.

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

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.

  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.

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.
