arm64: dts: allwinner: h5: Add system-control node with SRAM C1 (973efbc6) · Commits · 戴 / test

Add the H5-specific system control node description to its device-tree with support for the SRAM C1 section, that will be used by the video codec node later on. The CPU-side SRAM address was obtained empirically while the size was taken from the documentation. They may not be entirely accurate. Signed-off-by:
