From 05aec357871f892eea91d8b808f96a6091dd5310 Mon Sep 17 00:00:00 2001 From: Bert Vermeulen Date: Wed, 15 Apr 2015 17:43:52 +0200 Subject: spi: Add SPI driver for Mikrotik RB4xx series boards This driver mediates access between the connected CPLD and other devices on the bus. The m25p80-compatible boot flash and (some models) MMC use regular SPI, bitbanged as required by the SoC. However the SPI-connected CPLD has a two-wire mode, in which two bits are transferred per SPI clock cycle. The second bit is transmitted with the SoC's CS2 pin.
