2023-12-06arm64: dts: rockchip: Fix eMMC Data Strobe PD on rk3588Sam Edwards
JEDEC standard JESD84-B51 defines the eMMC Data Strobe line, which is currently used only in HS400 mode, as a device->host clock signal that "is used only in read operation. The Data Strobe is always High-Z (not driven by the device and pulled down by RDS) or Driven Low in write operation, except during CRC status response." RDS is a pull-down resistor specified in the 10K-100K ohm range. Thus per the standard, the Data Strobe is always pulled to ground (by the eMMC and/or RDS) during write operations. Evidently, the eMMC host controller in the RK3588 considers an active voltage on the eMMC-DS line during a write to be an error. The default (i.e. hardware reset, and Rockchip BSP) behavior for the RK3588 is to activate the eMMC-DS pin's builtin pull-down. As a result, many RK3588 board designers do not bother adding a dedicated RDS resistor, instead relying on the RK3588's internal bias. The current devicetree, however, disables this bias (`pcfg_pull_none`), breaking HS400-mode writes for boards without a dedicated RDS, but with an eMMC chip that chooses to High-Z (instead of drive-low) the eMMC-DS line. (The Turing RK1 is one such board.) Fix this by changing the bias in the (common) emmc_data_strobe case to reflect the expected hardware/BSP behavior. This is unlikely to cause regressions elsewhere: the pull-down is only relevant for High-Z eMMCs, and if this is redundant with a (dedicated) RDS resistor, the effective result is only a lower resistance to ground -- where the range of tolerance is quite high. If it does, it's better fixed in the specific devicetrees.

2023-12-05arm64: dts: imx8mp: imx8mq: Add parkmode-disable-ss-quirk on DWC3Nathan Rossi
The i.MX8MP and i.MX8MQ devices both use the same DWC3 controller and are both affected by a known issue with the controller due to specific behaviour when park mode is enabled in SuperSpeed host mode operation. Under heavy USB traffic from multiple endpoints the controller will sometimes incorrectly process transactions such that some transactions are lost, or the controller may hang when processing transactions. When the controller hangs it does not recover. This issue is documented partially within the linux-imx vendor kernel which references a Synopsys STAR number 9001415732 in commits [1] and additional details in [2]. Those commits provide some additional controller internal implementation specifics around the incorrect behaviour of the SuperSpeed host controller operation when park mode is enabled. The summary of this issue is that the host controller can incorrectly enter/exit park mode such that part of the controller is in a state which behaves as if in park mode even though it is not. In this state the controller incorrectly calculates the number of TRBs available which results in incorrect access of the internal caches causing the overwrite of pending requests in the cache which should have been processed but are ignored. This can cause the controller to drop the requests or hang waiting for the pending state of the dropped requests. The workaround for this issue is to disable park mode for SuperSpeed operation of the controller through the GUCTL1[17] bit. This is already available as a quirk for the DWC3 controller and can be enabled via the 'snps,parkmode-disable-ss-quirk' device tree property. It is possible to replicate this failure on an i.MX8MP EVK with a USB Hub connecting 4 SuperSpeed USB flash drives. Performing continuous small read operations (dd if=/dev/sd... of=/dev/null bs=16) on the block devices will result in device errors initially and will eventually result in the controller hanging.

The rk3399-gru PCI node addresses are wrong. In rk3399-gru-scarlet, the bus number in the address should be 0. This is because bus number assignment is dynamic and not known up front. For FDT, the bus number is simply ignored. In rk3399-gru-chromebook, the addresses are simply invalid. The first "reg" entry must be the configuration space for the device. The entry should be all 0s except for device/slot and function numbers. The existing 64-bit memory space (0x83000000) entries are not valid because they must have the BAR address in the lower byte of the first cell. Warnings for these are enabled by adding the missing 'device_type = "pci"' for the root port node.

The pinctrls for the hym8563 interrupt line and fan-tach input were both mistakenly defined as `pcfg_pull_none`. As these are active-low signals (level-triggered, in the hym8563 case) which may not be driven at times, these should really be pull-up. The lack of any bias results in spurious interrupts. Fix this by modifying the `rockchip,pins` properties as necessary to enable the pull-up resistors.

2023-11-29arm64: dts: mediatek: mt8186: fix clock names for power domainsEugen Hristev
Clocks for each power domain are split into big categories: pd clocks and subsys clocks. According to the binding, all clocks which have a dash '-' in their name are treated as subsys clocks, and must be placed at the end of the list. The other clocks which are pd clocks must come first. Fixed the naming and the placing of all clocks in the power domains. For the avoidance of doubt, prefixed all subsys clocks with the 'subsys' prefix. The binding does not enforce strict clock names, the driver uses them in bulk, only making a difference for pd clocks vs subsys clocks. The above problem appears to be trivial, however, it leads to incorrect power up and power down sequence of the power domains, because some clocks will be mistakenly taken for subsys clocks and viceversa. One consequence is the fact that if the DIS power domain goes power down and power back up during the boot process, when it comes back up, there are still transactions left on the bus which makes the display inoperable. Some of the clocks for the DIS power domain were wrongly using '_' instead of '-', which again made these clocks being treated as pd clocks instead of subsys clocks.

Commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images") addressed such a bad scenario. A similar symptom occurs with the following command: $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi [ snip ] SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image OBJCOPY arch/arm64/boot/Image AS arch/arm64/boot/zboot-header.o PAD arch/arm64/boot/vmlinux.bin GZIP arch/arm64/boot/vmlinuz OBJCOPY arch/arm64/boot/vmlinuz.o LD arch/arm64/boot/vmlinuz.efi.elf OBJCOPY arch/arm64/boot/vmlinuz.efi The log "OBJCOPY arch/arm64/boot/Image" is displayed twice. It indicates that two threads simultaneously enter arch/arm64/boot/ and write to arch/arm64/boot/Image.

When CONFIG_RODATA_FULL_DEFAULT_ENABLED=y, passing "rodata=on" on the kernel command-line (rather than "rodata=full") should turn off the "full" behaviour, leaving writable linear aliases of read-only kernel memory. Unfortunately, the option has no effect in this situation and the only way to disable the "rodata=full" behaviour is to disable rodata protection entirely by passing "rodata=off". Fix this by parsing the "on" and "off" options in the arch code, additionally enforcing that 'rodata_full' cannot be set without also setting 'rodata_enabled', allowing us to simplify a couple of checks in the process.

2023-11-08arm64: Move MediaTek GIC quirk handling from irqchip to coreDouglas Anderson
In commit 44bd78dd2b88 ("irqchip/gic-v3: Disable pseudo NMIs on MediaTek devices w/ firmware issues") we added a method for detecting MediaTek devices with broken firmware and disabled pseudo-NMI. While that worked, it didn't address the problem at a deep enough level. The fundamental issue with this broken firmware is that it's not saving and restoring several important GICR registers. The current list is believed to be: * GICR_NUM_IPRIORITYR * GICR_CTLR * GICR_ISPENDR0 * GICR_ISACTIVER0 * GICR_NSACR Pseudo-NMI didn't work because it was the only thing (currently) in the kernel that relied on the broken registers, so forcing pseudo-NMI off was an effective fix. However, it could be observed that calling system_uses_irq_prio_masking() on these systems still returned "true". That caused confusion and led to the need for commit a07a59415217 ("arm64: smp: avoid NMI IPIs with broken MediaTek FW"). It's worried that the incorrect value returned by system_uses_irq_prio_masking() on these systems will continue to confuse future developers. Let's fix the issue a little more completely by disabling IRQ priorities at a deeper level in the kernel. Once we do this we can revert some of the other bits of code dealing with this quirk. This includes a partial revert of commit 44bd78dd2b88 ("irqchip/gic-v3: Disable pseudo NMIs on MediaTek devices w/ firmware issues"). This isn't a full revert because it leaves some of the changes to the "quirks" structure around in case future code needs it.

Support for audio, compute and modem DSPs on Qualcomm SM6375, and the audio DSP in SC7180 are introduced. The peripheral NoC clock is dropped from MSM8996 modem DSP, as this is handled through the interconnect provider. In the zynqmp driver the setup for TCM memory, and device address translation thereof, when operating in lockstep mode is corrected. A few bug fixes and cleanups are introduces across the ST and STM32 remoteproc drivers" * tag 'rproc-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (28 commits) remoteproc: st: Fix sometimes uninitialized ret in st_rproc_probe() remoteproc: st: Use device_get_match_data() remoteproc: zynqmp: Change tcm address translation method remoteproc: mediatek: Refactor single core check and fix retrocompatibility remoteproc: qcom: q6v5-mss: Remove PNoC clock from 8996 MSS dt-bindings: remoteproc: qcom,msm8996-mss-pil: Remove PNoC clock dt-bindings: remoteproc: qcom,adsp: Remove AGGRE2 clock remoteproc: qcom: pas: Add SM6375 MPSS remoteproc: qcom: pas: Add SM6375 ADSP & CDSP dt-bindings: remoteproc: qcom,sm6375-pas: Document remoteprocs dt-bindings: remoteproc: pru: Add Interrupt property remoteproc: qcom: pas: Add sc7180 adsp dt-bindings: remoteproc: qcom: sc7180-pas: Add ADSP compatible arm64: dts: mediatek: Update the node name of SCP rpmsg subnode remoteproc: zynqmp: fix TCM carveouts in lockstep mode remoteproc: mediatek: Refine ipi handler error message remoteproc: mediatek: Report watchdog crash to all cores remoteproc: mediatek: Handle MT8195 SCP core 1 watchdog timeout remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM offset remoteproc: mediatek: Remove dependency of MT8195 SCP L2TCM power control on dual-core SCP ...
2023-11-07arm64/arm: arm_pmuv3: perf: Don't truncate 64-bit registersIlkka Koskinen
The driver used to truncate several 64-bit registers such as PMCEID[n] registers used to describe whether architectural and microarchitectural events in range 0x4000-0x401f exist. Due to discarding the bits, the driver made the events invisible, even if they existed. Moreover, PMCCFILTR and PMCR registers have additional bits in the upper 32 bits. This patch makes them available although they aren't currently used. Finally, functions handling PMXEVCNTR and PMXEVTYPER registers are removed as they not being used at all.
