Subject: drm/tegra: Use symbolic names for gr2d registers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=497c56a5817f1610ca189e1dc546934c7ce8eb7d;p=linux-beck.git

drm/tegra: Use symbolic names for gr2d registers

Instead of using magic numbers for the registers which contain memory
addresses in the firewall table, using symbolic names.
