Subject: dt-bindings: display: tegra: document Tegra30 VI and VIP
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d262d030baef287da33344a932639aab5f913c3a;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: display: tegra: document Tegra30 VI and VIP

Existing Parallel VI interface schema for Tegra20 is fully compatible with
Tegra30; hence, lets reuse it by setting fallback for Tegra30.

Adjust existing VI schema to reflect that Tegra20 VI is compatible with
Tegra30 by setting a fallback for Tegra30. Additionally, switch to using
an enum instead of list of const.
