From 738f66d3211d7ae0cd0012ba6457dac9a03bfd6b Mon Sep 17 00:00:00 2001 From: Michael Turquette Date: Mon, 23 May 2016 15:44:26 -0700 Subject: [PATCH] clk: gxbb: add AmLogic GXBB clk controller driver The gxbb clock controller is the primary clock generation unit for the AmLogic GXBB SoC. It is clocked by a fixed 24MHz xtal, contains several PLLs and the usual post-dividers, muxes, dividers and leaf gates that are fed into various IP blocks in the SoC.
