Now LP55xx provides automatic clock detection API, lp55xx_is_extclk_used().
The clock configuration can be done by the driver itself.
(a) Concept
The default value is set by each driver with clock selection.
The internal clock selection bit is updated in case that the external clock
is not detected or clock rate is not 32KHz.
(b) Change on LP55xx platform data
The clock configuration is done automatically, so no need to define
'update_config' in the platform side.
Correlated information are removed in the documentations and header.
(c) Definitions moved from header to driver files
CONFIG register values are moved each driver, LP5521 and LP5562.
Not necessary definitions are removed also.

According to a sysfs documentation(Documentation/filesystem/sysfs.txt),
scnprintf() should be used in a read operation method.
It guarantees safe buffer size(PAGE_SIZE) which is allocated by the sysfs.

LP55xx common driver provides generic firmware interface
for running a LED pattern.
LP5521 and LP5523 have many device attributes for running patterns.
This patch cleans up those complex code.
Removed device attributes:
engine1_mode
engine2_mode
engine3_mode
engine1_load
engine2_load
engine3_load
led_pattern
All device attributes and functions are replaced with two callback functions,
'firmware_cb' and 'run_engine'.
New engine functions:
lp5521_load/stop/run_engine(), lp5521_update_program_memory() and
lp5521_wait_opmode_done()

LED current is configurable via the sysfs.
Max current is a read-only attribute.
These attributes code can be shared in lp55xx common driver.
Device attributes: 'led_current' and 'max_current'
move to lp55xx common driver
Replaced functions:
show_max_current() => lp55xx_show_max_current()
show_current() => lp55xx_show_current()
store_current() => lp55xx_store_current()
LED setting function: set_led_current()
Current registers are device specific, so configurable function is added

lp5521_set_brightness() and lp5523_set_brightness() are replaced with
common function, lp55xx_set_brightness().
This function is invoked when the brightness of each LED channel is updated.
LP5521 and LP5523 have different register address for the brightness control,
so this work is done by chip specific brightness_work_fn().

LED class devices are registered in lp5521_register_leds() and
lp5523_register_leds().
Two separate functions are merged into consolidated lp55xx function,
lp55xx_register_leds().
Error handling fix:
Unregistering LEDS are handled in lp55xx_register_leds() when LED registration
failure occurs. So each driver error handler is changed to 'err_register_leds'
Chip dependency: 'brightness_work_fn' and 'set_led_current'
To make the structure abstract, both functions are configured in each driver.
Those functions should be done by each driver because register control is
chip-dependant work.

Engine initialization is done by reset command in lp5521_init_device().
Remove this duplicate code.

leds-lp5521:
When 'lp5521_init_device()' gets failed, error handling should be 'fail1'
rather than 'fail2'.
fail1: releasing platform resource and return code
fail2: releasing allocated LED devices with handling 'fail1'
The 'lp5521_init_device()' is called before creating LED devices.
Thus, 'goto fail1' is proper error handler of this function.

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.
