7 title: LEDs connected to Broadcom BCM6328 controller
10 - Álvaro Fernández Rojas <noltari@gmail.com>
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
17 as spi-gpio. See
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
22 controlled, so the only chance to keep them working is by using this driver.
27 is usually 1:1 for hardware to LED signals, but through the activity/link
29 explained later in brcm,link-signal-sources). Even if a LED is hardware
30 controlled you are still able to make it blink or light it up if it isn't,
31 but you can't turn it off if the hardware decides to light it up. For this
34 Each LED is represented as a sub-node of the brcm,bcm6328-leds device.
