From 5e7752436e10427ba598de4f2f6b7889daf586cc Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 8 Apr 2015 17:23:20 +0200 Subject: [PATCH] gpu: host1x: mipi: Add Tegra210 support Some changes are needed to the configuration settings for some lanes. In addition, the clock lanes for the CSI pads can no longer be calibrated.
