Subject: dt-bindings: display: bridge: ldb: Add check for reg and reg-names
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8aa2f0ac08d3b207ba54e98698c9d696b86452a7;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: display: bridge: ldb: Add check for reg and reg-names

Make "reg" property mandatory for all LDB devices and "reg-names"
mandatory for i.MX8MP and i.MX93 which have two "reg" values. The
i.MX6SX has only one "reg" value so the "reg-names" property there
is optional and not needed.
