Subject: ARM: tegra: tf700t: upgrade video bindings
X-Git-Tag: v2025.07-rc1~18^2~12^2~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a2846e7adeb2c9287ad4ed8c6ea8e7b2a5219c2;p=pandora-u-boot.git

ARM: tegra: tf700t: upgrade video bindings

Align TF700T bindings with existing upstream device trees. OF_UPSTREAM
migration is possible already but resulting size of binary exceeds maximum
allowed size with full size trees.
