platform/chrome: cros_ec_lightbar - Add lightbar program feature to sysfs
Add a program feature so we can upload and run programs for lightbar sequences. We should be able to use this to shift sequences out of the EC and save space there. $ cat <suitable program bin> > /sys/devices/.../cros_ec/program $ echo program > /sys/devices/.../cros_ec/sequence Signed-off-by: Eric Caruso <ejcaruso@chromium.org> Signed-off-by: Guenter Roeck <groeck@chromium.org> Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Benson Leung <bleung@chromium.org>
