2013-02-21checkpatch: fix USLEEP_RANGE testBruce Allan1-2/+2
Do not test udelay() for a value less than 10usec when passed a variable instead of a hard-coded number; there is no way for checkpatch to know the value of the variable. As it is today, it will complain about variables with alphanumeric characters plus '_', e.g. foo_bar, but not variables with other characters, eg. foo->bar.

2013-02-21decompressors: make the default XZ_DEC_* config match the selected architectureFlorian Fainelli1-6/+6
Change the defautl XZ_DEC_* config symbol to match the configured architecture. It is perfectly legitimate to support multiple XZ BCJ filters for different architectures (e.g.: to mount foreign squashfs/xz compressed filesystems), it is however more natural not to select them all by default, but only the one matching the configured architecture.

2013-02-21backlight: lp855x_bl: support new LP8557 deviceKim, Milo4-18/+94
LP8557 is one of LP855x family device, but it has different register map and initialization process. To support this device, device specific configuration is done through the lp855x_device_config structure. Few register definitions are fixed for better readability. BRIGHTNESS_CTRL -> LP855X_BRIGHTNESS_CTRL DEVICE_CTRL -> LP855X_DEVICE_CTRL EEPROM_START -> LP855X_EEPROM_START EEPROM_END -> LP855X_EEPROM_END EPROM_START -> LP8556_EPROM_START EPROM_END -> LP8556_EPROM_END And LP8557 register definitions are added. New register function, lp855x_update_bit() is added.

2013-02-21backlight: lp855x_bl: introduce device configuration flowKim, Milo1-10/+68
At this moment, LP855x device driver has fixed register configuration. For example, fixed register addresses and values are set on the device initialization. But new device of LP855x family, LP8557 has different register map and initialization sequence. To support new device architecture, initialization process should be changed. Introduce new structure: lp855x_device_config ============================================= With lp855x_device_config, device specific features are configurable. Use configurable function calls and register addresses rather than fixed values. Change on device initialization =============================== In old LP855x driver architecture, the device initialization was simple. - Just update the brightness/device control register/ROM area(optional). In new LP855x driver architecture, two more works are added - pre_init and post_init. Those init functions are optional, used for new device LP8557. New device initialization flow: generic sequence ================================================= 1) pre_init_device() 2) update the brightness register 3) update the device control register 4) update ROM area if need 5) post_init_device() Name change =========== Use generic name 'lp855x_configure()' instead of 'lp855x_init_registers()'.

2013-02-21backlight: add an AS3711 PMIC backlight driverGuennadi Liakhovetski3-0/+388
This is an initial commit of a backlight driver, using step-up DCDC power supplies on AS3711 PMIC. Only one mode has actually been tested, several further modes have been implemented "dry," but disabled to avoid accidental hardware damage. Anyone wishing to use any of those modes will have to modify the driver. Tested on sh73a0-based kzm9g board. Only one mode has been tested and is enabled. That mode copies the sample code from the manufacturer. Deviations from that code proved to be fatal for the hardware...
