2025-06-10clk: renesas: Add support for R9A09G077 SoCThierry Bultel
RZ/T2H has 2 register blocks at different addresses. The clock tree has configurable dividers and mux selectors. Add these new clock types, new register layout type, and registration code for mux and div in registration callback.

2025-06-10clk: renesas: Pass sub struct of cpg_mssr_priv to cpg_clk_registerThierry Bultel
In a subsequent patch, the registration callback will need more parameters from cpg_mssr_priv (like another base address with clock controllers with double register block, and also, notifiers and rmw_lock). Instead of adding more parameters, move the needed parameters to a public sub-struct. Instead moving clks to this structure, which would have implied to add an allocation (and cleanup) for it, keep the way the allocation is done and just have a copy of the pointer in the public structure.

2025-06-10clk: renesas: rzg2l: Move pointers after hw memberClaudiu Beznea
Reorder the pointer members in struct mstp_clock so they appear immediately after the hw member. This helps avoid potential padding and eliminates the need for any calculations in the to_mod_clock() macro. As struct clk_hw currently contains only pointers, placing it first also avoids padding.

2025-06-10clk: renesas: rzg2l: Postpone updating priv->clks[]Claudiu Beznea
Since the sibling data is filled after the priv->clks[] array entry is populated, the first clock that is probed and has a sibling will temporarily behave as its own sibling until its actual sibling is populated.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This has been a semi-quiet cycle. The core framework remains unchanged this time around. In terms of shiny new code though, we have support for the SpacemiT K1 SoC, Sophgo SG2044, and T-HEAD TH1520 VO clk drivers joining the usual silicon players like Qualcomm, Samsung, Allwinner, and Renesas. Surprisingly, the Qualcomm pile was smaller than usual but that is likely because they put one SoC support inside a driver for a different SoC that is very similar. Other than all those new clk drivers there are the usual clk data updates to fix parents, frequency tables, and add missing clks along with some Kconfig changes to make compile testing simpler and even more DT binding conversions to boot. The exciting part is still the new SoC support like SpacemiT and Sophgo support though, which really dominate the diffstat because they introduce a whole new silicon vendor clk driver. New Drivers: - Camera clock controller driver for Qualcomm QCS8300 - DE (display engine) 3.3 clocks on Allwinner H616 - Samsung ExynosAutov920 CPU cluster CL0, CL1 and CL2 clock controllers - Video Output (VO) subsystem clk controller in the T-HEAD TH1520 SoC - Clock driver for Sophgo SG2044 - Clock driver for SpacemiT K1 SoC - Renesas RZ/V2N (R9A09G056) SoC clk driver Updates: - Correct data in various SoC clk drivers - Allow clkaN to be optional in the Qualcomm RPMh clock controller driver if command db doesn't define it - Change Kconfig options to not enable by default during compile testing - Add missing clks in various SoC clk drivers - Remove some duplicate clk DT bindings and convert some more to YAML" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (93 commits) clk: qcom: gcc-x1e80100: Set FORCE MEM CORE for UFS clocks clk: qcom: gcc: Set FORCE_MEM_CORE_ON for gcc_ufs_axi_clk for 8650/8750 clk: qcom: rpmh: make clkaN optional clk: qcom: Add support for Camera Clock Controller on QCS8300 clk: rockchip: rk3528: add slab.h header include clk: rockchip: rk3576: add missing slab.h include clk: meson: Do not enable by default during compile testing clk: meson-g12a: add missing fclk_div2 to spicc clk: qcom: gcc-msm8939: Fix mclk0 & mclk1 for 24 MHz clk: rockchip: rename gate-grf clk file clk: rockchip: rename branch_muxgrf to branch_grf_mux clk: sunxi-ng: ccu: add Display Engine 3.3 (DE33) support dt-bindings: allwinner: add H616 DE33 clock binding clk: samsung: correct clock summary for hsi1 block dt-bindings: clock: add SM6350 QCOM video clock bindings clk: rockchip: Pass NULL as reg pointer when registering GRF MMC clocks clk: sunxi-ng: h616: Add LVDS reset for LCD TCON dt-bindings: clock: sun50i-h616-ccu: Add LVDS reset clk: rockchip: rk3036: mark ddrphy as critical clk: rockchip: rk3036: fix implementation of usb480m clock mux ...

2025-05-14clk: sunxi-ng: d1: Add missing divider for MMC mod clocksAndre Przywara
The D1/R528/T113 SoCs have a hidden divider of 2 in the MMC mod clocks, just as other recent SoCs. So far we did not describe that, which led to the resulting MMC clock rate to be only half of its intended value. Use a macro that allows to describe a fixed post-divider, to compensate for that divisor. This brings the MMC performance on those SoCs to its expected level, so about 23 MB/s for SD cards, instead of the 11 MB/s measured so far.

The DE33 is a newer version of the Allwinner Display Engine IP block, found in the H616, H618, H700 and T507 SoCs. DE2 and DE3 are already supported by the mainline driver. The DE33 in the H616 has mixer0 and writeback units. The clocks and resets required are identical to the H3 and H5 respectively, so use those existing structs for the H616 description. There are two additional 32-bit registers (at offsets 0x24 and 0x28) which require clearing and setting respectively to bring up the hardware. The function of these registers is currently unknown, and the values are taken from the out-of-tree driver. Add the required clock description struct and compatible string to the DE2 driver.

2025-05-08clk: s2mps11: initialise clk_hw_onecell_data::num before accessing ::hws[] ↵André Draszik
in probe() With UBSAN enabled, we're getting the following trace: UBSAN: array-index-out-of-bounds in .../drivers/clk/clk-s2mps11.c:186:3 index 0 is out of range for type 'struct clk_hw *[] __counted_by(num)' (aka 'struct clk_hw *[]') This is because commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with __counted_by") annotated the hws member of that struct with __counted_by, which informs the bounds sanitizer about the number of elements in hws, so that it can warn when hws is accessed out of bounds. As noted in that change, the __counted_by member must be initialised with the number of elements before the first array access happens, otherwise there will be a warning from each access prior to the initialisation because the number of elements is zero. This occurs in s2mps11_clk_probe() due to ::num being assigned after ::hws access. Move the assignment to satisfy the requirement of assign-before-access.

The T-Head TH1520 SoC integrates a variety of clocks for its subsystems, including the Application Processor (AP) and the Video Output (VO) [1]. Up until now, the T-Head clock driver only supported AP clocks. Extend the driver to provide clock functionality for the VO subsystem. At this stage, the focus is on implementing the VO clock gates, as these are currently the most relevant and required components for enabling and disabling the VO subsystem functionality. Future enhancements may introduce additional VO-related clocks as necessary.
