Subject: [PATCH 1/4] mxs_spi: unbreak driver
Date: Tue, 10 Sep 2013 19:13:31 +0200	[thread overview]
Message-ID: <1378833214-19808-1-git-send-email-eric@eukrea.com> (raw)

since the switch to common clock, SPI driver reports :
MXS: Timeout resetting block via register 0x80014000
mxs_spi mxs_spi2: MXS SPI: Timeout waiting for start

The reason is that the clock is not enabled anywhere in
the driver.
