From 26ad30e9d3ec445f61f94910fb14cc6e7d8efa25 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 30 Aug 2015 16:55:28 -0600 Subject: rockchip: Add basic peripheral and clock definitions Add header files for the peripherals and clocks supported on Rockchip platforms. The particular implementation (and register set) for each is SoC-specific, but it seems that the naming can be generic.
