| * clk: qcom: Use ARRAY_SIZE in dispcc-sc7180 for parent clocksDouglas Anderson2020-02-031-11/+11
| | | | | | | | | | | | | | | | | | | | It's nicer to use ARRAY_SIZE instead of hardcoding. Had we always been doing this it would have prevented a previous bug. See commit 74c31ff9c84a ("clk: qcom: gpu_cc_gmu_clk_src has 5 parents, not 6").

| * clk: qcom: Get rid of fallback global names for dispcc-sc7180Douglas Anderson2020-02-031-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the new world input clocks should be matched by ".fw_name". sc7180 is new enough that no backward compatibility use of global names should be needed. Remove it. With a proper device tree and downstream display patches I have verified booting a sc7180 up and seeing the display after this patch.

| * clk: qcom: Don't overwrite 'cfg' in clk_rcg2_dfs_populate_freq()Stephen Boyd2020-02-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DFS frequency table logic overwrites 'cfg' while detecting the parent clk and then later on in clk_rcg2_dfs_populate_freq() we use that same variable to figure out the mode of the clk, either MND or not. Add a new variable to hold the parent clk bit so that 'cfg' is left untouched for use later. This fixes problems in detecting the supported frequencies for any clks in DFS mode.

In the core, we allow clk_ops::init() to return an error code now so that we can fail clk registration if the callback does something like fail to allocate memory. We also add a new "terminate" clk_op so that things done in clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now when critical clks fail to enable and we support changing clk rates and enable/disable state through debugfs when developers compile the kernel themselves. On the driver front, we get support for what seems like a lot of Qualcomm and NXP SoCs given that those vendors dominate the diffstat. There are a couple new drivers for Xilinx and Amlogic SoCs too. The updates are all small things like fixing the way glitch free muxes switch parents, avoiding div-by-zero problems, or fixing data like parent names. See the updates section below for more details. Finally, the "basic" clk types have been converted to support specifying parents with clk_hw pointers. This work includes an overhaul of the fixed-rate clk type to be more modern by using clk_hw APIs. Core: - Let clk_ops::init() return an error code - Add a clk_ops::terminate() callback to undo clk_ops::init() - Warn about critical clks that fail to enable or prepare - Support dangerous debugfs actions on clks with dead code New Drivers: - Support for Xilinx Versal platform clks - Display clk controller on qcom sc7180 - Video clk controller on qcom sc7180 - Graphics clk controller on qcom sc7180 - CPU PLLs for qcom msm8916 - Move qcom msm8974 gfx3d clk to RPM control - Display port clk support on qcom sdm845 SoCs - Global clk controller on qcom ipq6018 - Add a driver for BCLK of Freescale SAI cores - Add cam, vpe and sgx clock support for TI dra7 - Add aess clock support for TI omap5 - Enable clks for CPUfreq on Allwinner A64 SoCs - Add Amlogic meson8b DDR clock controller - Add input clocks to Amlogic meson8b controllers - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2 - i.MX8MP clk driver support Updates: - Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs - Detect more PRMCU variants in ux500 driver - Adjust the composite clk type to new way of describing clk parents - Fixes for clk controllers on qcom msm8998 SoCs - Fix gmac main clock for TI dra7 - Move TI dra7-atl clock header to correct location - Fix hidden node name dependency on TI clkctrl clocks - Fix Amlogic meson8b mali clock update using the glitch free mux - Fix Amlogic pll driver division by zero at init - Prepare for split of Renesas R-Car H3 ES1.x and ES2.0+ config symbols - Switch more i.MX clk drivers to clk_hw based APIs - Disable non-functional divider between pll4_audio_div and pll4_post_div on imx6q - Fix watchdog2 clock name typo in imx7ulp clock driver - Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs - Suppress bind attrs for i.MX8M clock driver - Add a big comment in imx8qxp-lpcg driver to tell why devm_platform_ioremap_resource() shouldn't be used for the driver - A correction on i.MX8MN usb1_ctrl parent clock setting" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (140 commits) dt/bindings: clk: fsl,plldig: Drop 'bindings' from schema id clk: ls1028a: Fix warning on clamp() usage clk: qoriq: add ls1088a hwaccel clocks support clk: ls1028a: Add clock driver for Display output interface dt/bindings: clk: Add YAML schemas for LS1028A Display Clock bindings clk: fsl-sai: new driver dt-bindings: clock: document the fsl-sai driver clk: composite: add _register_composite_pdata() variants clk: qcom: rpmh: Sort OF match table dt-bindings: fix warnings in validation of qcom,gcc.yaml dt-binding: fix compilation error of the example in qcom,gcc.yaml clk: zynqmp: Add support for clock with CLK_DIVIDER_POWER_OF_TWO flag clk: zynqmp: Fix divider calculation clk: zynqmp: Add support for get max divider clk: zynqmp: Warn user if clock user are more than allowed clk: zynqmp: Extend driver for versal dt-bindings: clock: Add bindings for versal clock driver clk: ti: clkctrl: Fix hidden dependency to node name clk: ti: add clkctrl data dra7 sgx clk: ti: omap5: Add missing AESS clock ...

If CPUFREQ is enabled, early during the system boot, it might attempt to change the CPU frequency ("set_rate"). If the HFPLL is selected as a provider, it will then change the rate for this clock. As boot continues, clk_disable_unused_subtree will run. Since it wont find a valid counter (enable_count) for a clock that is actually enabled it will attempt to disable it which will cause the CPU to stop. Notice that in this driver, calls to check whether the clock is enabled are routed via the is_enabled callback which queries the hardware. The following commit, rather than marking the clock critical and forcing the clock to be always enabled, addresses the above scenario making sure the clock is not disabled but it continues to rely on the firmware to enable the clock.

It would be great if we could specify the frequency table as a single entry constant ratio instead of a long list, ie: { .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 }, { } So, lets support that. We need to fix a corner case in qcom_find_freq() where if the freq table is non-null, but has no frequencies, we end up returning an "entry" before the table array, which is bad. Then, we need ignore the freq from the table, and instead base everything on the requested freq.

That analysis had a flaw, which caused the pnoc to be skipped. The pnoc clock needs to be on to access the uart for the console. The clock is on from boot, but has no consumer votes in the RPM. When we attempt to boot the modem, it causes the RPM to turn off pnoc, which kills our access to the console and causes CPU hangs. We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in an implicit vote for linux and prevent issues when booting modem. Hopefully pnoc can be consumed by the interconnect framework in future so that Linux can rely on explicit votes.

That change has been sitting in next for a while now but maybe something is still broken. We'l see. Other than that the core framework changes aren't invasive and they're fixing bugs, simplifying, and making things better. On the clk driver side we got the usual addition of new SoC support, new features for existing drivers, and bug fixes scattered throughout. The biggest diffstat is the Amlogic driver that gained CPU clk support in addition to migrating to the new way of specifying clk parents. After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and clock controllers from those vendors. Core: - Drop NULL checks in clk debugfs - Add min/max rates to clk debugfs - Set clk_init_data pointer inside clk_hw to NULL after registration - Make clk_bulk_get_all() return an 'id' corresponding to clock-names - Evict parents from parent cache when they're unregistered New Drivers: - Add clock driver for i.MX8MN SoCs - Support aspeed AST2600 SoCs - Support for Mediatek MT6779 SoCs - Support qcom SM8150 GCC and RPMh clks - Support qcom QCS404 WCSS clks - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807) - Addition of clock driver for Rockchip rk3308 SoCs Updates: - Add regulator support to the cdce925 clk driver - Add support for Raspberry Pi 4 bcm2711 SoCs - Add SDIO gate support to aspeed driver - Add missing of_node_put() calls in various clk drivers - Migrate Amlogic driver to new clock parent description method - Add DVFS support to Amlogic Meson g12 - Add Amlogic Meson g12a reset support to the axg audio clock controller - Add sm1 support to the Amlogic Meson g12a clock controller - Switch i.MX8MM clock driver to platform driver - Add Hifi4 DSP related clocks for i.MX8QXP SoC - Fix Audio PLL setting and parent clock for USB - Misc i.MX8 clock driver improvements and corrections - Set floor ops for Qualcomm SD clks so that rounding works - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1 - Enable the Allwinner V3 SoC and fix the i2s clock for H6" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: Drop !clk checks in debugfs dumping clk: imx: imx8mn: fix pll mux bit clk: imx: imx8mm: fix pll mux bit clk: imx: clk-pll14xx: unbypass PLL by default clk: imx: pll14xx: avoid glitch when set rate clk: mvebu: ap80x: add AP807 clock support clk: mvebu: ap806: Prepare the introduction of AP807 clock support clk: mvebu: ap806: add AP-DCLK (hclk) to system controller driver clk: mvebu: ap806: be more explicit on what SaR is clk: mvebu: ap80x-cpu: add AP807 CPU clock support clk: mvebu: ap806-cpu: prepare mapping of AP807 CPU clock dt-bindings: ap806: Document AP807 clock compatible dt-bindings: ap80x: Document AP807 CPU clock compatible clk: sprd: add missing kfree clk: at91: allow 24 Mhz clock as input for PLL clk: Make clk_bulk_get_all() return a valid "id" clk: actions: Fix factor clk struct member access clk: qcom: rcg: Return failure for RCG update clk: remove extra ---help--- tags in Kconfig clk: add include guard to clk-conf.h ...
