Greer" Date: Fri, 23 Aug 2013 14:12:35 -0700 Subject: ARM: dts: AM33XX: Add SHAM data and documentation Add the generic AM33XX SHAM module's device tree data and enable it for the am335x-evm, am335x-evmsk, and am335x-bone platforms. Also add Documentation file describing the data for the SHAM module. Cc: Paul Walmsley Signed-off-by: Mark A.
