Indeed, depending on configuration, those data can be unused. mark those data as __maybe_unused to avoid compilation warnings.

The at91 platform gains support for sam9x7 chips in the soc and power management code. This is the latest variant of one of the oldest still supported SoC families, using the ARM9 (ARMv5) core. As usual, the qualcomm snapdragon platform gets a ton of updates in many of their drivers to add more features and additional SoC support. Most of these are somewhat firmware related as the platform has a number of firmware based interfaces to the kernel. A notable addition here is the inclusion of trace events to two of these drivers. Herve Codina and Christophe Leroy are now sending updates for drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC and Arm specific platforms and has previously been problematic to maintain. The first update here contains support for newer PowerPC variants and some cleanups. The turris mox firmware driver has a number of updates, mostly cleanups. The Arm SCMI firmware driver gets a major rework to modularize the existing code into separately loadable drivers for the various transports, the addition of custom NXP i.MX9 interfaces and a number of smaller updates. The Arm FF-A firmware driver gets a feature update to support the v1.2 version of the specification. The reset controller drivers have some smaller cleanups and a newly added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs. The memory controller drivers get some cleanups and refactoring for Tegra, TI, Freescale/NXP and a couple more platforms. Finally there are lots of minor updates to firmware (raspberry pi, tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic, mediatek) drivers and their DT bindings" * tag 'soc-drivers-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (212 commits) firmware: imx: remove duplicate scmi_imx_misc_ctrl_get() platform: cznic: turris-omnia-mcu: Fix error check in omnia_mcu_register_trng() bus: sunxi-rsb: Simplify code with dev_err_probe() soc: fsl: qe: ucc: Export ucc_mux_set_grant_tsa_bkpt soc: fsl: cpm1: qmc: Fix dependency on fsl_soc.h dt-bindings: arm: rockchip: Add rk3576 compatible string to pmu.yaml soc: fsl: qbman: Remove redundant warnings soc: fsl: qbman: Use iommu_paging_domain_alloc() MAINTAINERS: Add QE files related to the Freescale QMC controller soc: fsl: cpm1: qmc: Handle QUICC Engine (QE) soft-qmc firmware soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation soc: fsl: qe: Add missing PUSHSCHED command soc: fsl: qe: Add resource-managed muram allocators soc: fsl: cpm1: qmc: Introduce qmc_version soc: fsl: cpm1: qmc: Rename SCC_GSMRL_MODE_QMC soc: fsl: cpm1: qmc: Handle RPACK initialization soc: fsl: cpm1: qmc: Rename qmc_chan_command() soc: fsl: cpm1: qmc: Introduce qmc_{init,exit}_xcc() and their CPM1 version soc: fsl: cpm1: qmc: Introduce qmc_init_resource() and its CPM1 version soc: fsl: cpm1: qmc: Re-order probe() operations ...

As for the mutex_sof table since this directly contains the values to write to the DISP_MUTEXn_CTL register, which has only bits [13:0] (so this register is effectively 14 bits long), change that to use unsigned 16-bits. The type of mutex_{mod,sof}_reg was also changed to 16 bits, as the maximum value that those will ever have is 0x800, because it calculates as 0x30 + (0x20 * n) where n's maximum value is 63.

This header is provided by powerpc architecture and the functions it declares are defined only when FSL_SOC is selected. Today the dependency is the following: depends on CPM1 || QUICC_ENGINE || \ (FSL_SOC && (CPM || QUICC_ENGINE) && COMPILE_TEST) This dependency tentatively ensure that FSL_SOC is there when doing a COMPILE_TEST. CPM1 is only selected by PPC_8xx and cannot be selected manually. CPM1 selects FSL_SOC QUICC_ENGINE on the other hand can be selected by ARM or ARM64 which doesn't select FSL_SOC. QUICC_ENGINE can also be selected with just COMPILE_TEST. It is therefore possible to end up with CPM_QMC selected without FSL_SOC. So fix it by making it depend on FSL_SOC at all time. The rest of the above dependency is the same as the one for CPM_TSA on which CPM_QMC also depends, so it can go away, leaving only a simple dependency on FSL_SOC.

CPM1 version is already supported and, as the QE version of those component are pretty similar to the CPM1 version, the series extend the already existing drivers to support for the QE version. The TSA and QMC components are tightly coupled and so the series provides modifications on both components. Of course, this series can be split if it is needed. Let me know. The series is composed of: - Patches 1 and 2: Fixes related to TRNSYNC in the QMC driver - Patches 3..6: Fixes of checkpatch detected issues in the TSA driver - Patch 7: The QE TSA device-tree binding - Patches 8..13: TSA driver preparations for adding support for QE - Patches 14 and 15: The support for QE in TSA + MAINTAINERS update - Patch 16: A TSA API improvement needed for the QE QMC driver - Patch 17: A clarification in the QE QMC driver - Patches 18..22: Fixes of checkpatch detected issues in the QMC driver - Patch 23: The QE QMC device-tree binding - Patches 24..31: QMC driver preparations for adding support for QE - Patches 32 and 33: Missing features additions in QE code - Patches 34..36: The QMC support for QE in QMC + MAINTAINERS update Compared to the previous iteration, this v2 series updates device-tree bindings and fixes issues detected by kernel test robots. Related to the QE QMC device-tree binding, I kept the unit address in decimal and the 3 compatible strings. ================ Link: https://lore.kernel.org/r/20240808071132.149251-1-herve.codina@bootlin.com Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Tested-by: Christophe Leroy <christophe.leroy@csgroup.eu>

This QE QMC is similar to the CPM QMC except that it uses UCCs (Unified Communication Controllers) instead of SCCs (Serial Communication Controllers). Also, compared against the CPM QMC, this QE QMC does not use a fixed area for the UCC/SCC parameters area but it uses a dynamic area allocated and provided to the hardware at runtime.
