H A Dleds-bcm6328.txt1 LEDs connected to Broadcom BCM6328 controller
4 In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
5 However, on some devices there are Serial LEDs (LEDs connected to a 74x164
7 as spi-gpio. See Documentation/devicetree/bindings/gpio/gpio-74x164.txt), or
9 Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
10 exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
