Pull clk updates from Stephen Boyd: "There's not much to see in the core framework this time around. Instead the majority of the diff is the normal collection of driver additions for new SoCs and non-critical clk data fixes and updates. The framework must be middle aged. The two biggest directories in the diffstat show that the Qualcomm and Unisoc support added a handful of big drivers for new SoCs but that's not really the whole story because those new drivers tend to add large numbers of lines of clk data. There's a handful of AT91 clk drivers added this time around too and a bunch of improvements to drivers like the i.MX driver. All around lots of updates and fixes in various clk drivers which is good to see. The core framework has only one real major change which has been baking in next for the past couple months. It fixes the framework so that it stops caching a clk's phase when the phase clk_op returns an error. Before this change we would consider some negative errno as a phase and that just doesn't make sense. Core: - Don't show clk phase when it is invalid New Drivers: - Add support for Unisoc SC9863A clks - Qualcomm SM8250 RPMh and MSM8976 RPM clks - Qualcomm SM8250 Global Clock Controller (GCC) support - Qualcomm SC7180 Modem Clock Controller (MSS CC) support - EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs - Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs Updates: - GPU GX GDSC support on Qualcomm sc7180 - Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers - A series from Anson to convert i.MX8 clock bindings to json-schema - Update i.MX pll14xx driver to include new frequency entries for pll1443x table, and return error for invalid PLL type - Add missing of_node_put() call for a number of i.MX clock drivers - Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already have the flag on its child cpu clock - Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL via CORE_SEL slice, and source from A53 CCM clk root when we need to change ARM PLL frequency. Thus, we can support core running above 1GHz safely - Update i.MX pfdv2 driver to check zero rate and use determine_rate for getting the best rate - Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d - Remove PMC clks from Tegra clk driver - Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector - Conversion to json-schema of the Renesas CPG/MSSR DT bindings - Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3 - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N - Update Amlogic audio clock gate hierarchy for meson8 and gxbb - Update Amlogic g12a spicc clock sources - Support for Ingenic X1000 TCU clks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (146 commits) clk: sprd: fix to get a correct ibias of pll dt-bindings: imx8mm-clock: Fix the file path dt-bindings: imx8mq-clock: Fix the file path clk: qcom: rpmh: Drop unnecessary semicolons clk: qcom: rpmh: Simplify clk_rpmh_bcm_send_cmd() clk: tegra: Use NULL for pointer initialization clk: sprd: add clocks support for SC9863A clk: sprd: support to get regmap from parent node clk: sprd: Add macros for referencing parents without strings clk: sprd: Add dt-bindings include file for SC9863A dt-bindings: clk: sprd: add bindings for sc9863a clock controller dt-bindings: clk: sprd: rename the common file name sprd.txt to SoC specific clk: sprd: add gate for pll clocks MAINTAINERS: dt: update reference for arm-integrator.txt clk: mmp2: Fix bit masks for LCDC I/O and pixel clocks clk: mmp2: Add clock for fifth SD HCI on MMP3 dt-bindings: marvell,mmp2: Add clock id for the fifth SD HCI on MMP3 clk: mmp2: Add clocks for the thermal sensors dt-bindings: marvell,mmp2: Add clock ids for the thermal sensors clk: mmp2: add the GPU clocks ...

clk: at91: move sam9x60's PLL register offsets to PMC header

2020-02-18T20:47:54Z

Move SAM9X60's PLL register offsets to PMC header so that the definitions would also be available from arch/arm/mach-at91/pm_suspend.S. This is necessary to disable/enable PLLA for SAM9X60 on suspend/resume.

clk: at91: usb: continue if clk_hw_round_rate() return zero

2020-02-12T23:31:47Z

clk_hw_round_rate() may call round rate function of its parents. In case of SAM9X60 two of USB parrents are PLLA and UPLL. These clocks are controlled by clk-sam9x60-pll.c driver. The round rate function for this driver is sam9x60_pll_round_rate() which call in turn sam9x60_pll_get_best_div_mul(). In case the requested rate is not in the proper range (rate < characteristics->output[0].min && rate > characteristics->output[0].max) the sam9x60_pll_round_rate() will return a negative number to its caller (called by clk_core_round_rate_nolock()). clk_hw_round_rate() will return zero in case a negative number is returned by clk_core_round_rate_nolock(). With this, the USB clock will continue its rate computation even caller of clk_hw_round_rate() returned an error. With this, the USB clock on SAM9X60 may not chose the best parent. I detected this after a suspend/resume cycle on SAM9X60.
