From 33608dcd01d0c0eb3f2442d88c8a97f1195bd2d5 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 2 Aug 2016 14:40:11 -0700 Subject: [PATCH 01/11] clk: gxbb: add MMC gate clocks, and expose for DT Add the SD/eMMC gate clocks and expose them for use by DT. While at it, also explose FCLK_DIV2 since this is one of the input clocks to the mux internal to each of the SD/eMMC blocks.

charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for the meson8b clock gates. Most of them are disabled by Amlogic U-Boot, but need to be enabled for ethernet, USB and many other components.
