From 12551f0239b50c88352e3292dd7703382addbf5e Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Wed, 24 Dec 2014 14:31:06 +0100 Subject: [PATCH] clk: rockchip: fix rk3066 pll lock bit location The bit locations indicating the locking status of the plls on rk3066 are shifted by one to the right when compared to the rk3188, bits [7:4] instead of [8:5] on the rk3188, thus indicating the locking state of the wrong pll or a completely different information in case of the gpll. The recently introduced pll init code exposed that problem on some rk3066 boards when it tried to bring the boot-pll value in line with the value from the rate table. Fix this by defining separate pll definitions for rk3066 with the correct locking indices.
