Subject: [PATCH] smc91x: disable DMA mode on the logicpd pxa270
Date: Fri, 23 Jun 2006 23:24:36 +0200 [thread overview]
Message-ID: <20060623212436.GB4843@xi.wantstofly.org> (raw)
Enabling PXA DMA for the smc91x on the logicpd pxa270 produces
unacceptable interference with the TFT panel, so disable it. Also
delete the lpd270 versions of the SMC_{in,out}[bl]() macros, as they
aren't used, since the board only supports 16bit accesses.
