From: Magnus Damm <[email protected]> Add part numbers for APE6 and current set of R-Car Gen2 SoCs to the IPMMU DT binding documentation. The example is also updated to show how the generic compatible string may be used as fallback.
Signed-off-by: Magnus Damm <[email protected]> --- Changes since V1: - Updated compat string section to the following: "Must contain SoC-specific and generic entries from below." Thanks to Laurent for feedback!
