git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers More Qualcomm driver changes for v5.20 This adds support for booting secondary cores, SPM, SMD-RPM and RPM power-domain support for the MSM8909 platform. It drops an unnecessary print in icc-bwmon, corrects SA8540P entries in socinfo and a Kconfig build dependency for QCOM_RPMPD. Lastly it continues to clean up up the Devicetree bindings for the Qualcomm drivers. * tag 'qcom-drivers-for-5.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: dt-bindings: soc: qcom: qcom,smd-rpm: add power-controller dt-bindings: soc: qcom: aoss: document qcom,sm8450-aoss-qmp dt-bindings: soc: qcom,rpmh-rsc: simplify qcom,tcs-config ARM: mach-qcom: Add support for MSM8909 dt-bindings: arm: cpus: Document "qcom,msm8909-smp" enable-method soc: qcom: spm: Add CPU data for MSM8909 dt-bindings: soc: qcom: spm: Add MSM8909 CPU compatible soc: qcom: rpmpd: Add compatible for MSM8909 dt-bindings: power: qcom-rpmpd: Add MSM8909 power domains soc: qcom: smd-rpm: Add compatible for MSM8909 dt-bindings: soc: qcom: smd-rpm: Add MSM8909 soc: qcom: icc-bwmon: Remove unnecessary print function dev_err() soc: qcom: socinfo: Fix the id of SA8540P SoC soc: qcom: Make QCOM_RPMPD depend on PM Link: https://lore.kernel.org/r/20220720230648.2113609-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.20 This introduces a new driver that requests interconnect bandwidth based on throughput measurements of the bwmon hardware blocks found associated with, among other things, the CPU subsystem on many Qualcomm platforms. It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path. The SCM DT bindings are updated to declare support for QCS404, SM6125 and SDX65. The command db driver has a strncpy() converted to strscpy_pad() and then back again with proper documentation to why this was the right API. * tag 'qcom-drivers-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: icc-bwmon: Add bandwidth monitoring driver dt-bindings: interconnect: qcom,msm8998-cpu-bwmon: add BWMON device soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register soc: qcom: llcc: Fix syntax errors in comments soc: qcom: ocmem: Fix refcount leak in of_get_ocmem dt-bindings: soc: qcom,wcnss: remove unneeded ref for names firmware: qcom_scm: Add bw voting support to the SCM interface dt-bindings: firmware: qcom-scm: Add interconnects property soc: qcom: cmd-db: replace strscpy_pad() with strncpy() dt-bindings: firmware: scm: Add compatible for SDX65 dt-bindings: arm: qcom: switch maintainer to Bjorn soc: qcom: rpmhpd: fix typos in comment soc: qcom: correct kerneldoc soc: qcom: cmd-db: replace strncpy() with strscpy_pad() firmware: qcom_scm-legacy: correct kerneldoc dt-bindings: firmware: document Qualcomm QCS404 and SM6125 SCM soc: qcom: apr: Drop redundant check in .remove() firmware: qcom_scm: drop unexpected word "the" soc: qcom: socinfo: Add an ID for sc7180P Link: https://lore.kernel.org/r/20220712021830.1271398-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. While at it, also remove a redundant call to of_address_to_resource(), as this was getting the address of the same resource index 0: we can as well get the iostart from the 'regs' pointer.

2022-07-07soc: mediatek: SVS: Use DEFINE_SIMPLE_DEV_PM_OPS for svs_pm_opsNathan Chancellor
When building this driver for an architecture that does not support CONFIG_PM_SLEEP, such as hexagon, the following warnings occur: drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function] static int svs_suspend(struct device *dev) ^ drivers/soc/mediatek/mtk-svs.c:1515:12: error: unused function 'svs_resume' [-Werror,-Wunused-function] static int svs_resume(struct device *dev) ^ 2 errors generated. This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS, which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the functions unused in the eyes of the compiler. This problem was rectified in commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones") with new macros. Use DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing svs_pm_ops when CONFIG_PM_SLEEP is set.

2022-07-07soc: mediatek: mtk-pm-domains: Allow probing vreg supply on two MFGsAngeloGioacchino Del Regno
MediaTek SoCs have multiple MFG power-domains, exclusively used for the GPU which, in turn, requires external power supplies: make sure to have the MTK_SCPD_DOMAIN_SUPPLY cap on the two topmost MFGs to allow voting for regulators on/off upon usage of these power domains. This also ensures that the SRAM is actually powered and that we're not relying on the bootloader leaving this supply on when performing the first (and latter) poweron sequence for these domains' sram.

2022-07-06soc: qcom: icc-bwmon: Add bandwidth monitoring driverKrzysztof Kozlowski
Bandwidth monitoring (BWMON) sits between various subsytems like CPU, GPU, Last Level caches and memory subsystem. The BWMON can be configured to monitor the data throuhput between memory and other subsytems. The throughput is measured within specified sampling window and is used to vote for corresponding interconnect bandwidth. Current implementation brings support for BWMON v4, used for example on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. The driver was tested on SDM845.
