7title: LEDs connected to Broadcom BCM6358 controller
8
9description: |
10  This controller is present on BCM6358 and BCM6368.
11  In these SoCs there are Serial LEDs (LEDs connected to a 74x164 controller),
12  which can either be controlled by software (exporting the 74x164 as spi-gpio.
13  See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml), or
14  by hardware using this driver.
