From 4b0f73055acaced436d5de909b26d001ea7f667c Mon Sep 17 00:00:00 2001 From: Maxime Jourdan Date: Tue, 19 Mar 2019 11:11:38 +0100 Subject: [PATCH] clk: meson-g12a: add video decoder clocks Add the necessary clock parts for: - VDEC_1: used to feed VDEC_1 - VDEC_HEVC: the "back" part of the VDEC_HEVC block - VDEC_HEVCF: the "front" part of the VDEC_HEVC block In previous SoC generations (GXL, GXBB), there was only one VDEC_HEVC clock, which got split in two parts for G12A.
