Subject: [PATCH v1] EMMA SPI driver
Date: Tue, 03 Sep 2013 16:55:02 +0000 [thread overview]
Message-ID: <1378227303-18795-1-git-send-email-ian.molton@codethink.co.uk> (raw)
Hi folks, This is a first cut at SPI for the EMEV2 (1?) platform.
The driver works on our hardware, however we have an unusual chipselect mux.
I've replaced that with a pure GPIO based chipselect option in the driver,
which would allow us to model the MUX as a gpiochip on our board. Sadly, I
do not have the time to work further on this, so this part is merely compile
tested.
I've had no problems running 4 slaves on GPIO chipselects (via the mux) at
1.5MHz
-Ian
