3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Heiko Stuebner <[email protected]> commit 12551f0239b50c88352e3292dd7703382addbf5e upstream. 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.
