Subject: [PATCH 22/22] [POWERPC] MPC832x_RDB: Update dts to use SPI1 in QE, register mmc_spi stub
Date: Thu, 13 Sep 2007 16:08:00 -0500 [thread overview]
Message-ID: <11897177143496-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <11897177132273-git-send-email-galak@kernel.crashing.org>
From: Anton Vorontsov <avorontsov@ru•mvista.com>
mmc_spi already tested to work. When it will hit mainline
the only change that will be needed is replacing "spidev"
with "mmc_spi".
