module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

clk: sunxi-ng: d1: Fix PLL_AUDIO0 preset

2024-11-02T11:19:47Z

To work around a limitation in our clock modelling, we try to force two bits in the AUDIO0 PLL to 0, in the CCU probe routine. However the ~ operator only applies to the first expression, and does not cover the second bit, so we end up clearing only bit 1. Group the bit-ORing with parentheses, to make it both clearer to read and actually correct.

clk: sunxi-ng: h616: Add sigma-delta modulation settings for audio PLL

2024-10-25T14:55:10Z

Allwinner has previously released a H616 audio driver which also provides sigma-delta modulation for the audio PLL clocks. This approach is used in other Allwinner SoCs, including the H3 and A64. The manual-provided clock values are: PLL_AUDIO(hs) = 24 MHz*N/M1 PLL_AUDIO(4X) = 24 MHz*N/M0/M1/P PLL_AUDIO(2X) = 24 MHz*N/M0/M1/P/2 PLL_AUDIO(1X) = 24 MHz*N/M0/M1/P/4 A fixed post-divider of 2 is used to account for a M0 divider of 2, which cannot be modelled by the existing macros and ccu_nm struct. Add SDM to the H616 clock control unit driver.

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

2024-07-19T19:16:28Z

Pull clk updates from Stephen Boyd: "This a large collection of clk driver updates and a handful of new SoC clk driver support. We have the usual Qualcomm clk drivers, along with clk drivers for the Sophgo and T-Head vendors, all to support some new SoCs. Nothing in particular stands out to me in the updates. There's the interconnect clk driver which exposes clks as interconnects, crossing subsystems. There's a bunch of janitorial things that are improving drivers in general like kmemdup_array() or fixing error paths. But overall the updates look normal to fix the description data which is usually the stuff that's wrong and/or untested. Core: - Skip gate basic type KUnit tests on s390 due to lack of MMIO emulation New Drivers: - AP sub-system clock controller in the T-Head TH1520 - Sophgo Sophon sg2042 clk driver - Qualcomm SM7150 camera, display and video clk drivers - Qualcomm QCM2290 GPU clk driver - Qualcomm QCS8386/QCS8084 NSS clk driver - Qualcomm SM8650 camera and video drivers Updates: - Add reset support to Airoha EN7581 clk driver - Add MODULE_DESCRIPTIONs to various clk drivers - Introduce helper logic to expose clock controllers as simple interconnect providers - Use the interconnect helper above on Qualcomm ipq9574 - Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on Qualcomm X1Elite - Improve error handling in Qualcomm kpss-xcc driver - Mark Qualcomm SC8280XP LPASS clock controller regmap_config const - Export more clocks for Rockchip rk3128 peripherals - Convert Rockchip clk drivers to use kmemdup_array() - Drop CLK_NR_CLKS from Rockchip rk3128 and rk3188 binding headers - Make qcom_cc_really_probe() take a struct device to allow reuse in non-platform-drivers - Introduce prepare-only branch clock ops in the qcom clk driver to support clocks on buses that take locks - Describe parent/child relationship for Qualcomm SC7280 camera GDSCs - Support Qualcomm Huayra 2290 alpha PLL - Adjust the highest SDCC clock frequency on Qualcomm IPQ6018 to match HS200 support - Add missing PCIe PIPE clocks on Qualcomm IPQ9574 - Fix various configurations and properties in the Qualcomm SA8775P, X1E80100 and SM7280 drivers - Park Qualcomm SM8350 GPU RCGs on XO while disabled - Remove unused CONFIG_QCOM_RPMCC Kconfig symbol - exynos-clkout: Remove usage of of_device_id table as .of_match_table, because the driver is instantiated as MFD cell, not as standalone platform driver. Populated .of_match_table confused people few times to convert the code to device_get_match_data(), which broke the driver - Mark one Samsung UFS clock as critical, because having it off stops the system from shutdown - Use kmemdup_array() when applicable - Remove unused 'struct gates_data' from old sunxi driver library - Add GPADC clock and reset for Allwinner H616 - Minor Amlogic S4 clock fixes - DT bindings Yaml conversion of the Amlogic AXG audio controller - Amlogic C3 clock controllers support - Amlogic clk flag added to skip init of already enabled PLLs and avoid relocking - Amlogic A1 DT bindings updates for system pll support - Add missing MODULE_DESCRIPTION where necessary - Remove obsolete clock DT binding header files - Add Battery Backup (VBATTB) and I2C clocks, resets, and power domains on Renesas RZ/G3S - Add audio clocks on Renesas R-Car V4M - Add video capture (ISPCS, CSI-2, VIN) clocks on Renesas R-Car V4M" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (135 commits) clk: thead: Add support for T-Head TH1520 AP_SUBSYS clocks dt-bindings: clock: Document T-Head TH1520 AP_SUBSYS controller clk: sophgo: Avoid -Wsometimes-uninitialized in sg2042_clk_pll_set_rate() clk/sophgo: Using BUG() instead of unreachable() in mmux_get_parent_id() clk: mxs: Use clamp() in clk_ref_round_rate() and clk_ref_set_rate() clk: sunxi-ng r40: Constify struct regmap_config clk: en7523: fix rate divider for slic and spi clocks clk: lpc32xx: Constify struct regmap_config clk: xilinx: Constify struct regmap_config clk: en7523: Remove PCIe reset open drain configuration for EN7581 clk: en7523: Remove pcie prepare/unpreare callbacks for EN7581 SoC clk: en7523: Add reset-controller support for EN7581 SoC dt-bindings: clock: airoha: Add reset support to EN7581 clock binding dt-bindings: clock: mediatek: Document reset cells for MT8188 sys clk: mediatek: mt8173-infracfg: Handle unallocated infracfg when module dt-bindings: clock: mediatek: add syscon compatible for mt7622 pciesys dt-bindings: clock: sprd,sc9860-clk: convert to YAML dt-bindings: clock: qoriq-clock: convert to yaml format clk: qcom: Park shared RCGs upon registration clk: qcom: ipq9574: Use icc-clk for enabling NoC related clocks ...

clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common

2024-06-30T15:12:44Z

In order to set the rate range of a hw sunxi_ccu_probe calls hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained in a ccu_common struct. This assumption is incorrect and, in consequence, causes invalid pointer de-references. Remove the faulty call. Instead, add one more loop that iterates over the ccu_clks and sets the rate range, if required. Fixes: b914ec33b391 ("clk: sunxi-ng: common: Support minimum and maximum rate") Reported-by: Robert J.
