Hello ! The PCA955x family of chips are I2C LED blinkers whose pins not used to control LEDs can be used as general purpose I/Os (GPIOs). The following adds support for device tree and Open Firmware to be able do define different operation modes for each pin. See bindings documentation for more details. The pca955x driver is then extended with a gpio_chip when pins are operating in GPIO mode. The driver follows the scheme of the leds-pca9532 driver which behaves quite similarly. Thanks, C. Changes since v2: - removed 'if (pdata)' tests Changes since v1: - split the patchset in two : DT support and GPIO support - introduced the use of devm_led_classdev_register() - replaced the 'compatible' property with 'type' - removed the 'gpio-base' property Cédric Le Goater (4): leds: pca955x: add device tree support leds: pca955x: use devm_led_classdev_register leds: pca955x: add GPIO support dt-bindings leds: add pca955x .../devicetree/bindings/leds/leds-pca955x.txt | 88 +++++++ drivers/leds/Kconfig | 11 + drivers/leds/leds-pca955x.c | 254 +++++++++++++++++---- include/dt-bindings/leds/leds-pca955x.h | 16 ++ 4 files changed, 323 insertions(+), 46 deletions(-) create mode 100644 Documentation/devicetree/bindings/leds/leds-pca955x.txt create mode 100644 include/dt-bindings/leds/leds-pca955x.h -- 2.7.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
