2017-03-10clk: rockchip: describe clk_gmac using the new muxgrf type on rk3328Elaine Zhang
With the newly introduced clk type for muxes in the grf we now can describe some missing clocks, like the clk_gmac2io and clk_gmac2phy that selects between clk_mac2io_src and gmac_clkin based on a bit set in the general register files.

2017-03-08clk: ti: convert to use proper register definition for all accessesTero Kristo
Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage.

2017-03-07clk: rockchip: Make uartpll a child of the gpll on rk3036Heiko Stuebner
The shared uart-pll is on boot a child of the apll that can get changed by cpu frequency scaling. So move it away to the more stable gpll to make sure the uart doesn't break on cpu frequency changes. This turned up during the 4.11 merge-window when commit 6a171b299379 ("serial: 8250_dw: Allow hardware flow control to be used") added general termios enablement making the uart on rk3036 change frequency and thus making it susceptible for the frequency scaling issue.

2017-03-06clk: sunxi-ng: mp: Adjust parent rate for pre-dividersChen-Yu Tsai
The MP style clocks support an mux with pre-dividers. While the driver correctly accounted for them in the .determine_rate callback, it did not in the .recalc_rate and .set_rate callbacks. This means when calculating the factors in the .set_rate callback, they would be off by a factor of the active pre-divider. Same goes for reading back the clock rate after it is set.

2017-03-06clk: rockchip: Set "ignore unused" for PMU M0 clocks on rk3399Douglas Anderson
The PMU Cortex M0 on rk3399 is intended to be used for things like DDRFreq transitions, suspend/resume, and other things that are the purview of ARM Trusted Firmware and not the kernel. As such, the kernel shouldn't be messing with the clocks. Add CLK_IGNORE_UNUSED to these clocks. Without this change, the following was observed on a Chromebook with a rk3399 (using not-yet-upstream ARM Trusted Firmware code and not-yet-upstream kernel code based on kernel-4.4): 1. We init the clock framework. 2. We start up "DDRFreq", which causes ATF to occasionally fire up the M0 for transitions. Each time ATF fires up the M0 it will turn on these clocks and each time it is done it will turn them off. 3. We finally get to the the part of the kernel that calls clk_disable_unused() and we disables the clocks. You can see the race above. Basically everything is fine as long as ARM Trusted Firmware isn't starting up the M0 at exactly the same time that the kernel is disabling unused clocks. ...but if the race happens then we go boom.

2017-02-14clk: mvebu: adjust clock handling for the CP110 system controllerThomas Petazzoni
This commit: - makes the GOP_DP (bit 9) gatable clock a child clock of the SD_MMC_GOP (bit 18) clock, as it should have been. The clock for bit 18 was just named SD_MMC, but since it also covers the GOP block, it is renamed SD_MMC_GOP. - makes the MG (bit 5) gatable clock a child clock of the MG_CORE clock (bit 6) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

This kzalloc() could fail. Let's bail out with -ENOMEM here instead of NULL dereferencing. That silences static checkers.

2017-01-30PM / OPP: Update OPP users to put referenceViresh Kumar
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. Note that some of the OPP core routines have gained rcu_read_{lock|unlock}() calls, as those still use RCU specific APIs within them.

2017-01-30clk: sunxi-ng: Add A80 Display Engine CCUChen-Yu Tsai
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.
