Subject: dt-bindings: serial: samsung: do not allow reg-io-width for gs101
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1d3f02abd551c69c6a82b9f22430b497b0bf7c55;p=linux.git

dt-bindings: serial: samsung: do not allow reg-io-width for gs101

All gs101 serial ports are restricted to 32-bit register accesses.
This requirement will be inferred from the compatible. Do not allow
the reg-io-width property for the google,gs101-uart compatible.
