From da4f2b4ccc49ab1f9e7ca7f32c1a3272806f48ce Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Wed, 11 Dec 2019 14:25:58 -0600 Subject: ARM: OMAP2+: am43xx: Add lcdc clockdomain As described in AM437x TRM, spruhl7h, Revised January 2018, there is an LCDC clockdomain present in the PER power domain. Although it is entirely unused on AM437x, it should be defined along with the other clockdomains so it can be shut off by Linux as there are no users.
