From cb9f8e6a737e60f460896111b32bbebc45aa1cd1 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Mon, 20 Apr 2015 07:53:48 +0200 Subject: [PATCH] video, ipu: make ldb clock frequency overwritable through board code the ldb clock can be setup in board code (for example set through PLL5). Update the ldb_clock rate also through board code. This should be removed, if a clock framework is availiable.
