drivers/video/backlight/aat2870_bl.c: fix setting max_current

2011-08-04T00:25:22+00:00

 - Current implementation tests wrong value for setting
   aat2870_bl->max_current.

 - In the current implementation, we cannot differentiate between 2 cases:

   a) if pdata->max_current is not set , or

   b) pdata->max_current is set to AAT2870_CURRENT_0_45 (which is also 0).

   Fix it by setting AAT2870_CURRENT_0_45 to be 1 and adjust the equation in
   aat2870_brightness() accordingly.

backlight: set backlight type and max_brightness before backlights are registered

2011-07-26T03:57:08+00:00

Since commit a19a6ee "backlight: Allow properties to be passed at
registration" and commit bb7ca74 "backlight: add backlight type", we can
set backlight type and max_brightness before backlights are registered.
Some newly added drivers did not set it properly, let's fix it.

backlight: add ams369fg06 amoled driver

2011-07-26T03:57:08+00:00

Add the ams369fg06 amoled panel driver.  The ams369fg06 amoled panel (480
x 800) driver uses 3-wired SPI inteface.  The brightness can be controlled
by gamma setting of amoled panel.
