[PATCH] spi: pl022: Add support for chip select extension

2014-09-10 Thread Anders Berg
Add support for a extended PL022 which has an extra register for controlling up to five chip select signals. This controller is found on the AXM5516 SoC. Unfortunately the PrimeCell identification registers are identical to a standard ARM PL022. To work around this, the peripheral ID must be overri
