7 title: LEDs connected to Broadcom BCM6328 controller
14   In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
15   However, on some devices there are Serial LEDs (LEDs connected to a 74x164
20   Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
21   exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
28   registers you have some limited control over rerouting the LEDs (as
32   reason, hardware controlled LEDs aren't registered as LED class devices.
34   Each LED is represented as a sub-node of the brcm,bcm6328-leds device.
