From 006f0dfb1d6dfa2bf7b1a08d2abcaf40eee6ae96 Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Thu, 13 May 2021 12:18:47 +0200 Subject: [PATCH] video: mxsfb: add enabling of "disp_axi" clock Some SoC needs "disp_axi" clock to be enabled, so let's try to retrieve it and enabling. If it fails it gives only a debug(), but this clock as well as "axi" clock is not mandatory.
