Date: Tue, 24 Nov 2009 10:25:33 +0200 From: Mike Rapoport <mike@...pulab.co.il> To: Richard Purdie <rpurdie@...ys.net> Cc: Eric Miao <eric.y.miao@...il.com>, linux-kernel@...r.kernel.org, Mike Rapoport <mike@...pulab.co.il> Subject: [PATCH] backlight: tdo24m: ensure chip select changes between transfers Some SPI host drivers do not change chip select betwen transfers unless .cs_chnage field is explicitly set. The LCD spec requires chip select change between consecuitive transfers, so ensure it at the SPI driver level.
