current implementation of the mxc_spi host driver gives issues,
if using more than one slave on the same bus. These patches try
to improve this use case.
They were tested on a TQMa6S (i.MX6S) with a custom mainboard
using two slave devices in SPI MODE 0 and 3, on of the devices
uses gpio based chip select the other hardware base chip select.
Markus Niebel (2):
SPI: mxc_spi: remove second reset from ECSPI config handler
SPI: mxc_spi: delay initialisation until claim bus
