2022-05-12arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUsShreyas K K1-0/+3
Add KRYO4XX gold/big cores to the list of CPUs that need the repeat TLBI workaround. Apply this to the affected KRYO4XX cores (rcpe to rfpe). The variant and revision bits are implementation defined and are different from the their Cortex CPU counterparts on which they are based on, i.e., (r0p0 to r3p0) is equivalent to (rcpe to rfpe).

2022-05-12dt-bindings: cpufreq: mediatek: Add MediaTek CCI propertyRex-BC Chen1-0/+7
MediaTek Cache Coherent Interconnect (CCI) uses software devfreq module for scaling clock frequency and adjust voltage. The phandle could be linked between CPU and MediaTek CCI for some MediaTek SoCs, like MT8183 and MT8186. The reason we need the link status between cpufreq and MediaTek cci is cpufreq and mediatek cci could share the same regulator in some MediaTek SoCs. Therefore, to prevent the issue of high frequency and low voltage, we need to use this to make sure mediatek cci is ready.

Every caller has a readily available vfio_device pointer, use that instead of passing in a generic struct device. The struct vfio_device already contains the group we need so this avoids complexity, extra refcountings, and a confusing lifecycle model.

2022-05-11rcu: Introduce CONFIG_RCU_EXP_CPU_STALL_TIMEOUTUladzislau Rezki2-0/+32
Currently both expedited and regular grace period stall warnings use a single timeout value that with units of seconds. However, recent Android use cases problem require a sub-100-millisecond expedited RCU CPU stall warning. Given that expedited RCU grace periods normally complete in far less than a single millisecond, especially for small systems, this is not unreasonable. Therefore introduce the CONFIG_RCU_EXP_CPU_STALL_TIMEOUT kernel configuration that defaults to 20 msec on Android and remains the same as that of the non-expedited stall warnings otherwise. It also can be changed in run-time via: /sys/.../parameters/rcu_exp_cpu_stall_timeout.

Qualcomm ARM DT updates for v5.19 This contains a long overdue overhaul of the MSM8974 DeviceTrees, aligning the style, structure and naming with what we've learned since the introduction of this platform. On top of this the Sony Rhine platform gained I2C masters, NFC and pstore support and the Fairphone 2 gained touchscreen support. For the new SDX65 platform reserved-memory nodes, rpmpd, SPMI, CPU clocks, SDHCI controller, SMMU and TCSR mutex was added. As was the initial DeviceTree for the related PMX65 PMIC. MSM8226 gained VADC and RTC support and support for the ASUS ZenWatch 2 was added. * tag 'qcom-dts-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (62 commits) ARM: dts: qcom: msm8974-FP2: Add supplies for remoteprocs ARM: dts: qcom: msm8974-FP2: Configure charger ARM: dts: qcom: msm8974-FP2: Add support for touchscreen ARM: dts: qcom: sdx55: Remove ipa interconnect node ARM: dts: qcom: msm8974: Add missing license headers ARM: dts: qcom: msm8974-FP2: Add mmc* aliases ARM: dts: qcom: msm8974-FP2: We're msm8974pro ARM: dts: qcom-msm8974*: Remove unnecessary include ARM: dts: qcom-msm8974-rhine: Add pstore node ARM: dts: qcom-msm8974-rhine: Add NFC and enable I2C hosts ARM: dts: qcom-msm8974*: Clean up old GPIO declarations ARM: dts: qcom-msm8974*: Consolidate I2C/UART/SDHCI ARM: dts: qcom-msm8974*: Enable IMEM unconditionally ARM: dts: qcom-msm8974: Sort and clean up nodes ARM: dts: qcom-msm8974: Convert ADSP to a MMIO device ARM: dts: qcom-msm8974pro-*: Use the 8974pro name in DT filenames ARM: dts: qcom-msm8974pro: Use &labels ARM: dts: qcom-msm8974-castor: Use &labels ARM: dts: qcom-msm8974-{"hon","am"}ami: Commonize and modernize the DTs ARM: dts: qcom-msm8974-klte: Use &labels ...

Qualcomm driver updates for v5.19 This converts a wide range of Qualcomm-related DeviceTree bindings to YAML, in order to improve our ability to validate the DeviceTree source. The RPMh power-domain driver gains support for the modem platform SDX65, the compute platform SC8280XP and the automotive platform SA8540p. While LLCC gains support for SC8180X and SC8280XP and gains a MODULE_DEVICE_TABLE() to make it functional as a module. It adds a driver for configuring the SSC bus, providing Linux access to the hardware blocks in the sensor subsystem. The socinfo driver gets confusion related to MSM8974 Pro sorted out and adds new ids for SM8540 and SC7280. The SCM driver gains support for MSM8974. Add missing of_node_put() in smp2p and smsm drivers. Stop using iterator after list_for_each_entry() and define static definitions as such, in the PDR driver. * tag 'qcom-drivers-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (33 commits) soc: qcom: pdr: use static for servreg_* variables soc: qcom: llcc: Add sc8180x and sc8280xp configurations dt-bindings: arm: msm: Add sc8180x and sc8280xp LLCC compatibles soc: qcom: rpmhpd: add sc8280xp & sa8540p rpmh power-domains soc: qcom: rpmhpd: Don't warn about sparse rpmhpd arrays dt-bindings: power: rpmpd: Add sc8280xp RPMh power-domains spi: dt-bindings: qcom,spi-geni-qcom: convert to dtschema soc: qcom: socinfo: Sort out 8974PRO names dt-bindings: soc: qcom,smp2p: convert to dtschema dt-bindings: qcom: geni-se: Update UART schema reference dt-bindings: qcom: geni-se: Update I2C schema reference dt-bindings: soc: qcom,rpmh-rsc: convert to dtschema bus: add driver for initializing the SSC bus on (some) qcom SoCs dt-bindings: bus: add device tree bindings for qcom,ssc-block-bus dt-bindings: qcom: qcom,geni-se: refer to dtschema for SPI dt-bindings: soc: qcom,smd: convert to dtschema firmware: qcom_scm: Add compatible for MSM8976 SoC dt-bindings: firmware: qcom-scm: Document msm8976 bindings soc: qcom: smem: validate fields of shared structures soc: qcom: smem: map only partitions used by local HOST ...
