BMC resets may occur whilst\nthe host is alive, thus the chassis and host system remain powered up. In these\ntwo patches I define an new devicetree property to describe the behaviour for\nGPIO LEDs and add support to the leds-gpio driver.\n\nChanges in v2:\n* Expand BMC to Baseboard Management Controller at least once in each commit\n message.\n\nv1: https://lkml.org/lkml/2017/8/25/44\n\nPlease review!\n\nCheers,\n\nAndrew\n\nAndrew Jeffery (2):\n dt-bindings: leds: gpio: Add optional retain-state-shutdown property\n leds: gpio: Allow LED to retain state at shutdown\n\n Documentation/devicetree/bindings/leds/leds-gpio.txt | 3 +++\n drivers/leds/leds-gpio.c | 7 ++++++-\n include/linux/leds.h | 2 ++\n 3 files changed, 11 insertions(+), 1 deletion(-)" }
