Subject: [PATCH 4/9] powerpc/86xx: Add MMC SPI support for MPC8610HPCD boards
Date: Fri, 1 May 2009 03:48:26 +0400 [thread overview]
Message-ID: <20090430234826.GD7901@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20090430234739.GA27709@oksana.dev.rtsoft.ru>
This patch adds spi and mmc-spi-slot nodes, plus a gpio-controller
for PIXIS' sdcsr bank that is used for managing SPI chip-select and
for reading card's states.
