Merge tag 'qcom-drivers-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.12 Support is added for making SCM driver configure the system either for a full or minimal ramdump following a system crash. The ramdump mode is changed from being enable-only to enable/disable as requested. The QSEECOM uefisecapp interface is allow-listed on Surface Laptop 7 and Lenovo Thinkpad T14s, providing EFI variable access. The change to match the SMD RPM driver based on the SMD channel name is reverted, in favor of stepping back to OF-based matching, as a means to get module autoloading to work properly. AOSS, APR, ICE, OCMEM, PBS and SMP2P drivers has error handling cleaned up using scoped resources. Trace events are added to the BWMON and SMP2P drivers, for better insights into their operations. The X1E LLCC configuration data is updated based on recommended values. A number of platforms are added to the in-kernel PD-mapper.

QMC driver requires fsl_soc.h to use function get_immrbase(). 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. Reported-by:

Herve Codina says: ================ This series add support for the QUICC Engine (QE) version of TSA and QMC components. 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.comSigned-off-by:

The PUSHSCHED command is missing in the QE header file. This command is supported on MPC8321 and is used to modify the start address for the task running on a given peripheral.

Current code handles the CPM1 version of QMC and initialize the QMC used SCC. The QUICC Engine (QE) version uses an UCC (Unified Communication Controllers) instead of the SCC (Serial Communication Controllers) used in the CPM1 version. These controllers serve the same purpose and are used in the same way but their inializations are slightly different. In order to prepare the support for QE version of QMC, introduce qmc_init_xcc() to initialize theses controllers (UCC in QE and SCC in CPM1) and isolate the CPM1 specific SCC initialization in a specific function. Also introduce qmc_exit_xcc() for consistency to revert operations done in qmc_init_xcc(). Signed-off-by:

Current code handles the CPM1 version of QMC. Resources initialisations (i.e. retrieving base addresses and offsets of different parts) will be slightly different in the QUICC Engine (QE) version. Indeed, in QE version, some resources need to be allocated and are no more "staticaly" defined. In order to prepare the support for QE version, introduce qmc_init_resource() to initialize those resources and isolate the CPM1 specific operations in a specific function. Signed-off-by:

Current code handles CPM1 version of QMC. In the QUICC Engine (QE) version, some operations done at probe() need to be done in a different order. In order to prepare the support for the QE version, changed the sequence of operation done at probe(): - Retrieve the tsa_serial earlier, before initializing resources. - Group SCC initialisation and do this initialization when it is really needed in the probe() sequence. Having the QE compatible sequence in the CPM1 version does not lead to any issue and works correctly without any regressions. Signed-off-by:
