Clearing the NSTBY bit in the control register also automatically clears the BLEN bit. So we need to make sure to set it again during resume, otherwise the backlight will stay off. Signed-off-by:

There is no need to return -EIO, because backlight_device_register() already returns correct error values. Signed-off-by:

gamma_table has 3 arrays which each hold MAX_GAMMA_LEVEL pointers to int. The current code sets ->gamma_table_count to 6 on 64bit arches and to 3 on 32 bit arches. It should be 3 on everything. Signed-off-by:

of_find_node_by_name() returns a node pointer with refcount incremented, use of_node_put() on it when done. of_find_node_by_name() will call of_node_put() against the node pass to from parameter, thus we also need to call of_node_get(from) before calling of_find_node_by_name(). Signed-off-by:

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... Signed-off-by:

Use the wrapper function for getting the driver data using lcd_device instead of using dev_get_drvdata with &ld->dev, so we can directly pass a struct lcd_device. Signed-off-by:
