2017-02-16clk: renesas: mstp: ensure register writes completeChris Brandt1-0/+6
When there is no status bit, it is possible for the clock enable/disable operation to have not completed by the time the driver code resumes execution. This is due to the fact that write operations are sometimes queued and delayed internally. Doing a read ensures the write operations has completed.

2017-01-30PM / OPP: Update OPP users to put referenceViresh Kumar1-11/+6
This patch updates dev_pm_opp_find_freq_*() routines to get a reference to the OPPs returned by them. Also updates the users of dev_pm_opp_find_freq_*() routines to call dev_pm_opp_put() after they are done using the OPPs. As it is guaranteed the that OPPs wouldn't get freed while being used, the RCU read side locking present with the users isn't required anymore. Drop it as well. This patch also updates all users of devfreq_recommended_opp() which was returning an OPP received from the OPP core.

2017-01-30clk: sunxi-ng: Add A80 Display Engine CCUChen-Yu Tsai3-0/+317
With the A80 SoC, Allwinner grouped and moved some subsystem specific clock controls to a separate address space, and possibly separate hardware block. One such subsystem is the display engine. The main clock control unit now only has 1 set of bus gate, dram gate, module clock, and reset control for the entire display subsystem. These feed into a secondary clock control unit, which has controls for each individual module of the display pipeline. This block is not documented in the user manual. Allwinner's kernel was used as the reference. Add support for the display engine clock controls found on the A80.

2017-01-30clk: sunxi-ng: mux: Fix determine_rate for mux clocks with pre-dividersChen-Yu Tsai1-3/+4
The determine_rate helper used ccu_mux_helper_adjust_parent_for_prediv() to adjust the parent_rate to account for pre-dividers, but then passed the pristine parent clock rate from clk_hw_get_rate() to the round() callback, thereby ignoring the pre-divider adjustment. In addition, it was saving the adjusted parent rate back into struct clk_rate_request. This patch fixes this by saving the pristine parent clock rate, and adding a copy that is adjusted and passed to the round() callback. The pristine copy, if it is the best solution, would be saved back to struct clk_rate_request.

The SoC supports up to 6 clocks (PMC_PLT_CLK[0..5]) with a frequency of either 19.2 MHz (PLL) or 25 MHz (XTAL) for BayTrail and a frequency of 19.2 MHz (XTAL) for CherryTrail. These clocks are available for general system use, where appropriate, and each have Control & Frequency register fields associated with them.

These clocks have been broken for a long time unfortunately, a hurdle of misc problems made them stop working at some point breaking USB and audio on Ux500. The platform as such and all "regular" clocks are migrated to OF/device tree, so let's migrate also this driver. With this patch and the corresponding DTS fixes, and a bunch of probe deferral fixes, audio starts working again on Ux500.
