leds: Add driver for LT3593 controlled LEDs
The LT3593 is a step-up DC/DC converter designed to drive up to ten white LEDs in series. The current flow can be set with a control pin. This driver controls any number of such devices connected on generic GPIOs and exports the function as as platform_driver. The gpio_led platform data struct definition is reused for this purpose. Successfully tested on a PXA embedded board. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
