Subject: [PATCH] plat-pxa: Enable ability to adjust SD/MMC clocks
Date: Sun, 19 Dec 2010 20:28:40 -0800 [thread overview]
Message-ID: <mailman.79.1293002018.1530.linux-arm-kernel@lists.infradead.org> (raw)
The PXA168, PXA910, and MMP2 SoC have the ability to adjust the SD/MMC
clock. This feature is useful and required depending on the board
design. Add infrastructure to support SD clock tuning.
