Current dts files with 'rockchip-pmu-sram' compatible nodes are now verified with sram.yaml, although the original text document still exists. Merge rockchip-pmu-sram.txt with sram.yaml by adding it as description with an example. Signed-off-by: Johan Jonker <jbx6244@gmail.com> --- Not tested with hardware.
