2013-06-20leds: lp55xx: support dynamic channel settings in the device tree structureKim, Milo1-8/+101
Currently, the LP55xx DT structure supports max 3 channels. However, LP5523 has max 9 channels and LP5562 has 4 channels. To enhance this constraint, the DT structure has been changed. (a) Use the child node for various channel settings instead of fixed array (b) Remove 'num_channel' property. This value can be retrieved by counting the children node. (c) 'chan-name' property supported (d) Documentation updates for LP5521 and LP5523 (cooloney@gmail.com: fix a coding style issue in leds-lp55xx.txt) Cc: Gabriel Fernandez <gabriel.fernandez@stericsson.com> Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Bryan Wu <cooloney@gmail.com>
