git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This contains no changes to the core framework. It is a collection of various clk driver updates. The biggest driver updates in terms of lines of code is the Allwinner driver, closely followed by the Qualcomm and Mediatek drivers. All of those hit high because we add so many lines of clk data. Coming in fourth place is i.MX which also adds a bunch of clk data. This accounts for the new driver additions this time around. Otherwise the patches are lots of little cleanups and fixes for various clk drivers that have baked in linux-next for a while. I suppose one highlight or theme is that more clk drivers are being updated to work as modules, which is interesting to see such critical SoC infrastructure work as a loadable module. New Drivers: - Support qcom SM8150/SM8250 video and display clks - Support Mediatek MT8167 clks - Add clock for CRC block found on vf610 SoCs - Add support for the Renesas R-Car V3U (R8A779A0) SoC - Add support for the VSP for Resizing clock on Renesas RZ/G1H - Support Allwinner A100 SoC clks Removed Drivers: - Remove i.MX21 clock driver, as i.MX21 platform support is being dropped Updates: - Change how qcom's display port clks work - Small non-critical fixes for TI clk driver - Remove various unused variables in clk drivers - Allow Rockchip clk driver to be a module - Remove most __clk_lookup() calls in Samsung drivers (yay!) - Support building i.MX ARMv8 platforms clock driver as module - Some kerneldoc fixes here and there - A couple of minor i.MX clk data corrections - Update audio clock inverter and fdiv2 flag on Amlogic g12 - Make amlogic clk drivers configurable in Kconfig - Fix Renesas VSP clock names to match corrected hardware documentation - Sigma-delta modulation on Allwinner R40 - Various fixes for at91 clk driver - Use semicolons instead of commas in some places - Mark some variables const so they can move to RO memory" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (102 commits) clk: imx8mq: Fix usdhc parents order clk: qcom: gdsc: Keep RETAIN_FF bit set if gdsc is already on clk: Restrict CLK_HSDK to ARC_SOC_HSDK clk: at91: sam9x60: support only two programmable clocks clk: ingenic: Respect CLK_SET_RATE_PARENT in .round_rate clk: ingenic: Don't tag custom clocks with CLK_SET_RATE_PARENT clk: ingenic: Don't use CLK_SET_RATE_GATE for PLL clk: ingenic: Use readl_poll_timeout instead of custom loop clk: ingenic: Use to_clk_info() macro for all clocks clk: bcm2835: add missing release if devm_clk_hw_register fails clk: at91: clk-sam9x60-pll: remove unused variable clk: at91: clk-main: update key before writing AT91_CKGR_MOR clk: at91: remove the checking of parent_name clk: clk-prima2: fix return value check in prima2_clk_init() clk: mmp2: Fix the display clock divider base clk: pxa: Constify static struct clk_ops clk: baikal-t1: Mark Ethernet PLL as critical clk: qoriq: modify MAX_PLL_DIV to 32 clk: axi-clkgen: Set power bits for fractional mode clk: axi-clkgen: Add support for fractional dividers ...

2020-06-19clk: bcm: rpi: Discover the firmware clocksMaxime Ripard
The RaspberryPi4 firmware actually exposes more clocks than are currently handled by the driver and we will need to change some of them directly based on the pixel rate for the display related clocks, or the load for the GPU. Since the firmware implements DVFS, this rate change can have a number of side-effects, including adjusting the various PLL voltages or the PLL parents. The firmware also implements thermal throttling, so even some thermal pressure can change those parameters behind Linux back. DVFS is currently implemented on the arm, core, h264, v3d, isp and hevc clocks, so updating any of them using the MMIO driver (and thus behind the firmware's back) can lead to troubles, the arm clock obviously being the most problematic. In order to make Linux play as nice as possible with those constraints, it makes sense to rely on the firmware clocks as much as possible. However, the firmware doesn't seem to provide some equivalents to their MMIO counterparts, so we can't really replace that driver entirely. Fortunately, the firmware has an interface to discover the clocks it exposes. Let's use it to discover, register the clocks in the clocks framework and then expose them through the device tree for consumers to use them.

2020-06-19clk: bcm: rpi: Allow the driver to be probed by DTMaxime Ripard
The current firmware clock driver for the RaspberryPi can only be probed by manually registering an associated platform_device. While this works fine for cpufreq where the device gets attached a clkdev lookup, it would be tedious to maintain a table of all the devices using one of the clocks exposed by the firmware. Since the DT on the other hand is the perfect place to store those associations, make the firmware clocks driver probe-able through the device tree so that we can represent it as a node.

There are four different callback functions that are used for the clk_register callback that all have different second parameter types. bcm2835_register_pll -> struct bcm2835_pll_data bcm2835_register_pll_divider -> struct bcm2835_pll_divider_data bcm2835_register_clock -> struct bcm2835_clock_data bcm2835_register_date -> struct bcm2835_gate_data These callbacks are cast to bcm2835_clk_register so that there is no error about incompatible pointer types. Unfortunately, this is a control flow integrity violation, which verifies that the callback function's types match the prototypes exactly before jumping.

2020-05-26clk: bcm2835: Fix return type of bcm2835_register_gateNathan Chancellor
bcm2835_register_gate is used as a callback for the clk_register member of bcm2835_clk_desc, which expects a struct clk_hw * return type but bcm2835_register_gate returns a struct clk *. This discrepancy is hidden by the fact that bcm2835_register_gate is cast to the typedef bcm2835_clk_register by the _REGISTER macro. This turns out to be a control flow integrity violation, which is how this was noticed. Change the return type of bcm2835_register_gate to be struct clk_hw * and use clk_hw_register_gate to do so. This should be a non-functional change as clk_register_gate calls clk_hw_register_gate anyways but this is needed to avoid issues with further changes.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features.
