Subject: [PATCH 0/3] Add mxs spi driver and mx28evk as its first user
Date: Mon, 4 Feb 2013 17:26:16 +0100 [thread overview]
Message-ID: <1359995179-2519-1-git-send-email-m.grzeschik@pengutronix.de> (raw)
this series adds support for the mxs spi driver
and adds the mx28evk as the first user to use it
with an m25p80 flash memory.
The driver was tested to work with the pio mode,
as its implementation has currently no dma support.
The SSP clock needed to be lower than the max possible
frequency for the flash. Otherwise it sometimes, after
a lot of spi transactions, the SSP stopped working.
