| | | | | | | | | | | | | | | | | | | | | | | | | | | | bitmap_for_each_{set,clear}_region() are similar to for_each_bit() macros in include/linux/find.h, but interface and implementation of them are different. This patch adds for_each_bitrange() macros and drops unused bitmap_*_region() API in sake of unification.

The real work that's in here is the typical pile of clk driver updates and new SoC support. Per usual (or maybe just recent trends), Qualcomm gains a handful of SoC drivers additions and has the largest diffstat. After that there are quite a few updates to the Allwinner (sunxi) drivers to support modular drivers and Renesas is heavily updated to add more support for various clks. Overall it looks pretty normal. New Drivers: - Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770 - MediaTek mt7986 SoC basic support - Clock and reset driver for Toshiba Visconti SoCs - Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8) - Allwinner D1 clks - Lan966x Generic Clock Controller driver and associated DT bindings - Qualcomm SDX65, SM8450, and MSM8976 GCC clks - Qualcomm SDX65 and SM8450 RPMh clks Updates: - Set suppress_bind_attrs to true for i.MX8ULP driver - Switch from do_div to div64_ul for throughout all i.MX drivers - Fix imx8mn_clko1_sels for i.MX8MN - Remove unused IPG_AUDIO_ROOT from i.MX8MP - Switch parent for audio_root_clk to audio ahb in i.MX8MP driver - Removal of all remaining uses of __clk_lookup() in drivers/clk/samsung - Refactoring of the CPU clocks registration to use common interface - An update of the Exynos850 driver (support for more clock domains) required by the E850-96 development board - Prep for runtime PM and generic power domains on Tegra - Support modular Allwinner clk drivers via platform bus - Lan966x clock driver extended to support clock gating - Add serial (SCI1), watchdog (WDT), timer (OSTM), SPI (RSPI), and thermal (TSU) clocks and resets on Renesas RZ/G2L - Rework SDHI clock handling in the Renesas R-Car Gen3 and RZ/G2 clock drivers, and in the Renesas SDHI driver - Make the Cortex-A55 (I) clock on Renesas RZ/G2L programmable - Document support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add GPU clock and resets on Renesas RZ/G2L - Add clk-provider.h to various Qualcomm clk drivers - devm version of clk_hw_register_gate() - kerneldoc fixes in a couple drivers" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (131 commits) clk: visconti: Remove pointless NULL check in visconti_pll_add_lookup() clk: mediatek: add mt7986 clock support clk: mediatek: add mt7986 clock IDs dt-bindings: clock: mediatek: document clk bindings for mediatek mt7986 SoC clk: mediatek: clk-gate: Use regmap_{set/clear}_bits helpers clk: mediatek: clk-gate: Shrink by adding clockgating bit check helper clk: x86: Fix clk_gate_flags for RV_CLK_GATE clk: x86: Use dynamic con_id string during clk registration ACPI: APD: Add a fmw property clk-name drivers: acpi: acpi_apd: Remove unused device property "is-rv" x86: clk: clk-fch: Add support for newer family of AMD's SOC clk: ingenic: Add MDMA and BDMA clocks dt-bindings: clk/ingenic: Add MDMA and BDMA clocks clk: bm1880: remove kfrees on static allocations clk: Drop unused COMMON_CLK_STM32MP157_SCMI config clk: st: clkgen-mux: search reg within node or parent clk: st: clkgen-fsyn: search reg within node or parent clk: Enable/Disable runtime PM for clk_summary MAINTAINERS: Add entries for Toshiba Visconti PLL and clock controller clk: visconti: Add support common clock driver and reset driver ...

For example, a generic arm64 kernel sees the following improvement when building the CCU core and drivers as modules: before: text data bss dec hex filename 13882360 5251670 360800 19494830 12977ae vmlinux after: text data bss dec hex filename 13734787 5086442 360800 19182029 124b1cd vmlinux So the result is a 390KB total reduction in kernel image size. The one early clock provider (sun5i) requires the core to be built in. Now that loading the MMC driver will trigger loading the CCU core, the MMC timing mode functions do not need a compile-time fallback.

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.

This case is handled by the dto_timer handler which will complete the request with the comment: /* * If DTO interrupt does NOT come in sending data state, * we should notify the driver to terminate current transfer * and report a data timeout to the core. */ But since the ARTPEC-8 DWMMC IP version, supports an extended TMOUT register which allows longer timeouts than the non ARTPEC-8 version does, waiting for the dto_timer to complete the request in error cases may cause the request to take significantly longer time than necessary. This is specifically true for the failing steps during tuning of a device. Fix this by completing the request when the error interrupt comes. Since this fix is specific for the ARTPEC-8, a quirk is added.

In this version the DATA_TIMEOUT field is split into two, which with the same 200MHz clock as above will allow a maximum timeout of: ((TMOUT[10:8] -1) * 0xFFFFFF + TMOUT[31:11] * 8) / 200000000 => ~587 ms Add driver callbacks for implementation specific data timeout, and implement callback functions for the ARTPEC-8 SoC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use feedback clock for HS200 mode, as for SDR104. The HS200 mode can be enabled through DT by using mmc-hs200-1_8v. It is possible to use it on STM32MP13, but not STM32MP15 platforms.

Set the max frequency of its source clock to 267MHz. The frequency used will be limited by the IOs max frequency, set in the SoC device tree.

Drop the mmc bus's match function that always returned 1 and so implements the same behaviour as when there is no match function.
