Subject: [patch 084/232] powerpc/85xx: add eSDHC support for MPC8536DS boards
Date: Tue, 22 Sep 2009 16:45:17 -0700	[thread overview]
Message-ID: <200909222345.n8MNjHtJ013999@imap1.linux-foundation.org> (raw)

From: Anton Vorontsov <avorontsov@ru.mvista.com>

This patch simply adds sdhci node to the device tree.

We specify clock-frequency manually, so that eSDHC will work without
upgrading U-Boot.  Though, that'll only work for default setup (1500 MHz)
on new board revisions.  For non-default setups, it's recommended to
upgrade U-Boot, since it will fixup clock-frequency automatically.
