1*4882a593SmuzhiyunBinding for Broadcom BCM6348/BCM6358 SPI controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".
5*4882a593Smuzhiyun- reg: Base address and size of the controllers memory area.
6*4882a593Smuzhiyun- interrupts: Interrupt for the SPI block.
7*4882a593Smuzhiyun- clocks: phandle of the SPI clock.
8*4882a593Smuzhiyun- clock-names: has to be "spi".
9*4882a593Smuzhiyun- #address-cells: <1>, as required by generic SPI binding.
10*4882a593Smuzhiyun- #size-cells: <0>, also as required by generic SPI binding.
11*4882a593Smuzhiyun
12*4882a593SmuzhiyunOptional properties:
13*4882a593Smuzhiyun- num-cs: some controllers have less than 8 cs signals. Defaults to 8
14*4882a593Smuzhiyun  if absent.
15*4882a593Smuzhiyun
16*4882a593SmuzhiyunChild nodes as per the generic SPI binding.
