2021-11-19clk: renesas: rcar-gen3: Switch to new SD clock handlingWolfram Sang
The old SD handling code was huge and could not handle all the details which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to another design. Have SDnH a separate clock, use the existing divider clocks and move the errata handling from the clock driver to the SDHI driver where it belongs. This patch removes the old SD handling code and switch to the new one. This updates the SDHI driver at the same time. Because the SDHI driver can only communicate with the clock driver via clk_set_rate(), I don't see an alternative to this flag-day-approach, so we cross subsystems here. The patch sadly looks messy for the CPG lib, but it is basically a huge chunk of code removed and smaller chunks added. It looks much better when you just view the resulting source file.

2021-11-19clk: renesas: rcar-gen3: Add dummy SDnH clockWolfram Sang
Currently, SDnH is handled together with SDn. This caused lots of problems, so we want SDnH as a separate clock. Introduce a dummy SDnH type here which creates a fixed-factor clock with factor 1. That allows us to convert the per-SoC CPG drivers while keeping the old behaviour for now. A later patch then will add the proper functionality.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Nothing changed in the clk framework core this time around. We did get some updates to the basic clk types to use determine_rate for the divider type and add a power of two fractional divider flag though. Otherwise, this is a collection of clk driver updates. More than half the diffstat is in the Qualcomm clk driver where we add a bunch of data to describe clks on various SoCs and fix bugs. The other big new thing in here is the Mediatek MT8192 clk driver. That's been under review for a while and it's nice to see that it's finally upstream. Beyond that it's the usual set of minor fixes and tweaks to clk drivers. There are some non-clk driver bits in here which have all been acked by the respective maintainers. New Drivers: - Support video, gpu, display clks on qcom sc7280 SoCs - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs - Multimedia clks (MMCC) on qcom MSM8994/MSM8992 - RPMh clks on qcom SM6350 SoCs - Support for Mediatek MT8192 SoCs - Add display (DU and DSI) clocks on Renesas R-Car V3U - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and resets on Renesas RZ/G2L Updates: - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators - Add power of two flag to fractional divider clk type - Migrate some clk drivers to clk_divider_ops.determine_rate - Migrate to clk_parent_data in gcc-sdm660 - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2 - Switch from .round_rate to .determine_rate in clk-divider-gate - Fix clock tree update for TF-A controlled clocks for all i.MX8M - Add missing M7 core clock for i.MX8MN - YAML conversion of rk3399 clock controller binding - Removal of GRF dependency for the rk3328/rk3036 pll types - Drop CLK_IS_CRITICAL flag from Tegra fuse clk - Make CLK_R9A06G032 Kconfig symbol invisible - Convert various DT bindings to YAML" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (128 commits) dt-bindings: clock: samsung: fix header path in example clk: tegra: fix old-style declaration clk: qcom: Add SM6350 GCC driver MAINTAINERS: clock: include S3C and S5P in Samsung SoC clock entry dt-bindings: clock: samsung: convert S5Pv210 AudSS to dtschema dt-bindings: clock: samsung: convert Exynos AudSS to dtschema dt-bindings: clock: samsung: convert Exynos4 to dtschema dt-bindings: clock: samsung: convert Exynos3250 to dtschema dt-bindings: clock: samsung: convert Exynos542x to dtschema dt-bindings: clock: samsung: add bindings for Exynos external clock dt-bindings: clock: samsung: convert Exynos5250 to dtschema clk: vc5: Add properties for configuring SD/OE behavior clk: vc5: Use dev_err_probe dt-bindings: clk: vc5: Add properties for configuring the SD/OE pin dt-bindings: clock: brcm,iproc-clocks: fix armpll properties clk: zynqmp: Fix kernel-doc format clk: at91: clk-generated: Limit the requested rate to our range clk: ralink: avoid to set 'CLK_IS_CRITICAL' flag for gates clk: zynqmp: Fix a memory leak clk: zynqmp: Check the return type ...

The probe was manually passing NULL instead of dev to devm_clk_hw_register. This caused a Unable to handle kernel NULL pointer dereference error. Fix this by passing 'dev'.

2021-08-13clk: renesas: Make CLK_R9A06G032 invisibleGeert Uytterhoeven
When configuring a kernel including support for Renesas ARM/ARM64 Socs, but excluding support for the RZ/N1D SoC, the user is always asked about the RZ/N1D clock driver. As this driver is already auto-selected when building a kernel including support for the RZ/N1D SoC, there is no need to make the CLK_R9A06G032 symbol visible, unless compile-testing. Align the symbol description with the other symbols.
