7 title: Broadcom's BCM63138 LEDs controller
10 - Rafał Miłecki <rafal@milecki.pl>
13 This LEDs controller was first used on BCM63138 and later reused on BCM4908,
16 It supports up to 32 LEDs that can be connected parallelly or serially. It
19 Binding serially connected LEDs isn't documented yet.

48 This describes the number of 8-bit serial shifters connected to the LED
49 controller block. The hardware is typically using 8-bit shift registers
50 with 8 LEDs per shift register, so 4 shifters results in 32 LEDs or 2
51 shifters give 16 LEDs etc, but the hardware supports any odd number of
52 registers. If left unspecified, the hardware boot-time default is used.
