Subject: [PATCH V2 2/2] ARM: dts: omap3-ldp: fix mmc configuration
Date: Thu, 13 Feb 2014 23:45:49 -0600 [thread overview]
Message-ID: <1392356749-32091-3-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1392356749-32091-1-git-send-email-nm@ti.com>
MMC1 is the only MMC interface available on the platform. Further,
since the platform is based on older revision of SoC which is not
capable of doing multi-block reads, mark it with compatibility for the
same and add pinmux to ensure that all relevant pins are configured
for non-MMC boot mode.

Changes since V1:
- fixed commit message as suggested by Balaji.
- update to use new compatible match for the erratum.
