2024-02-26clk: imx: imx8mp: Fix SAI_MCLK_SEL definitionShengjiu Wang
There is SAI1, SAI2, SAI3, SAI5, SAI6, SAI7 existing in this block control, the order is discontinuous. The definition of SAI_MCLK_SEL(n) is not match with the usage of CLK_SAIn(n). So define SAI##n##_MCLK_SEL separately to fix the issue.

2024-02-25clk: samsung: Add CPU clock support for Exynos850Sam Protsenko
Implement CPU clock control for Exynos850 SoC. It follows the same procedure which is already implemented for other SoCs in clk-cpu.c: 1. Set the correct rate for the alternate parent (if needed) before switching to use it as the CPU clock 2. Switch to the alternate parent, so the CPU continues to get clocked while the PLL is being re-configured 3. Adjust the dividers for the CPU related buses (ACLK, ATCLK, etc) 4. Re-configure the PLL for the new CPU clock rate. It's done automatically, as the CPU clock rate change propagates to the PLL clock, because the CPU clock has CLK_SET_RATE_PARENT flag set in exynos_register_cpu_clock() 5. Once the PLL is locked, set it back as the CPU clock source 6. Set alternate parent clock rate back to max speed As in already existing clk-cpu.c code, the divider and mux clocks are configured in a low-level fashion (using direct register access instead of CCF API), to avoid affecting how DIV and MUX clock flags are declared in the actual clock driver (clk-exynos850.c). No functional change. This patch adds support for Exynos850 CPU clock, but doesn't enable it per se.

2024-02-25clk: samsung: Keep register offsets in chip specific structureSam Protsenko
Abstract CPU clock registers by keeping their offsets in a dedicated chip specific structure to accommodate for oncoming Exynos850 support, which has different offsets for cluster 0 and cluster 1. This rework also makes it possible to use exynos_set_safe_div() for all chips, so exynos5433_set_safe_div() is removed here to reduce the code duplication. The ".regs" field has to be (void *) as different Exynos chips can have very different register layout, so this way it's possible for ".regs" to point to different structures, each representing its own chip's layout.

Keep chip specific data in the data structure, don't mix it with code. It makes it easier to add more chip specific data further.

2024-02-25clk: samsung: Pass register layout type explicitly to CLK_CPU()Sam Protsenko
Use a dedicated enum field to explicitly specify which register layout should be used for the CPU clock, instead of passing it as a bit flag. This way it would be possible to keep the chip-specific data in some array, where each chip structure could be accessed by its corresponding layout index. It prepares clk-cpu.c for adding new chips support, which might have different data for different CPU clusters. No functional change.

2024-02-25clk: samsung: Pass actual CPU clock registers base to CPU_CLK()Sam Protsenko
The documentation for struct exynos_cpuclk says .ctrl_base field should contain the controller base address. There are two different problems with that: 1. All Exynos clock drivers are actually passing CPU_SRC register offset via CPU_CLK() macro, which in turn gets assigned to mentioned .ctrl_base field. Because CPU_SRC register usually already has 0x200 offset from controller's base, all other register offsets in clk-cpu.c (like DIVs and MUXes) are specified as offsets from CPU_SRC offset, and not from controller's base. That makes things confusing and inconsistent with register offsets provided in Exynos clock drivers, also breaking the contract for .ctrl_base field as described in struct exynos_cpuclk doc. 2. Furthermore, some Exynos chips have an additional offset for the start of CPU clock registers block (inside of the CMU). There might be different reasons for that, e.g.: - The CMU contains clocks for two different CPUs (like in Exynos5420) - The CMU contains also non-CPU clocks as well (like in Exynos4) - The CPU CMU exists as a dedicated hardware block in the SoC layout, but is modelled as a part of bigger CMU in the driver (like in case of Exynos3250) That means the .ctrl_base field is actually not a controller's base, but instead it's a start address of the CPU clock registers inside of the CMU. Rework all register offsets in clk-cpu.c to be actual offsets from the CPU clock register block start, and fix offsets provided to CPU_CLK() macro in all Exynos clock drivers. Also clarify the .ctrl_base field documentation and rename it to just .base, because it doesn't really contain the CMU base. No functional change.

2024-02-25clk: samsung: Use single CPU clock notifier callback for all chipsSam Protsenko
Reduce the code duplication by making all chips use a single version of exynos_cpuclk_notifier_cb() function. That will prevent the code bloat when adding new chips support too. Also don't pass base address to pre/post rate change functions, as it can be easily derived from already passed cpuclk param. No functional change.

2024-02-16clk: qcom: drop the SC7180 Modem subsystem clock driverDmitry Baryshkov
This driver has never been used in the DT files merged to the kernel. According to Sibi, it only worked on the pre-production devices. For the production devices this functionality has been moved to the firmware. Drop the driver to remove possible confusion.
