There is a fix for boot time hangs that can happen on some am335x devices that started when the pruss devicetree nodes were added.

2021-09-30soc: ti: omap-prm: Fix external abort for am335x prussTony Lindgren1-12/+15
Starting with v5.15-rc1, we may now see some am335x beaglebone black device produce the following error on pruss probe: Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000 This has started with the enabling of pruss for am335x in the dts files. Turns out the is caused by the PRM reset handling not waiting for the reset bit to clear. To fix the issue, let's always wait for the reset bit to clear, even if there is a separate reset status register. We attempted to fix a similar issue for dra7 iva with a udelay() in commit effe89e40037 ("soc: ti: omap-prm: Fix occasional abort on reset deassert for dra7 iva"). There is no longer a need for the udelay() for dra7 iva reset either with the check added for reset bit clearing.

2021-09-20soc: qcom: mdt_loader: Drop PT_LOAD check on hash segmentShawn Guo1-1/+1
PT_LOAD type denotes that the segment should be loaded into the final firmware memory region. Hash segment is not one such, because it's only needed for PAS init and shouldn't be in the final firmware memory region. That's why mdt_phdr_valid() explicitly reject non PT_LOAD segment and hash segment. This actually makes the hash segment type check in qcom_mdt_read_metadata() unnecessary and redundant. For a hash segment, it won't be loaded into firmware memory region anyway, due to the QCOM_MDT_TYPE_HASH check in mdt_phdr_valid(), even if it has a PT_LOAD type for some reason (misusing or abusing?). Some firmware files on Sony phones are such examples, e.g WCNSS firmware of Sony Xperia M4 Aqua phone. The type of hash segment is just PT_LOAD. Drop the unnecessary hash segment type check in qcom_mdt_read_metadata() to fix firmware loading failure on these phones, while hash segment is still kept away from the final firmware memory region.

Support for compiling user space applications was already removed in gcc-4.9, and the kernel support for old applications could not be built with clang ias.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.15 This fixes the "shared memory state machine" (SMSM) interrupt logic to avoid missing transitions happening while the interrupts are masked. SM6115 support is added to smd-rpm and rpmpd. The Qualcomm SCM firmware driver is once again made possible to compile and load as a kernel module. An out-of-bounds error related to the cooling devices of the AOSS driver is corrected. The binding is converted to YAML and a generic compatible is introduced to reduce the driver churn. The GENI wrapper gains a helper function used in I2C and SPI for switching the serial engine hardware to use the wrapper's DMA-engine. Lastly it contains a number of cleanups and smaller fixes for rpmhpd, socinfo, CPR, mdt_loader and the GENI DT binding. * tag 'qcom-drivers-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: smsm: Fix missed interrupts if state changes while masked soc: qcom: smsm: Implement support for get_irqchip_state soc: qcom: mdt_loader: be more informative on errors dt-bindings: qcom: geni-se: document iommus soc: qcom: smd-rpm: Add SM6115 compatible soc: qcom: geni: Add support for gpi dma soc: qcom: geni: move GENI_IF_DISABLE_RO to common header PM: AVS: qcom-cpr: Use nvmem_cell_read_variable_le_u32() drivers: soc: qcom: rpmpd: Add SM6115 RPM Power Domains dt-bindings: power: rpmpd: Add SM6115 to rpmpd binding dt-bindings: soc: qcom: smd-rpm: Add SM6115 compatible soc: qcom: aoss: Fix the out of bound usage of cooling_devs firmware: qcom_scm: Allow qcom_scm driver to be loadable as a permenent module soc: qcom: socinfo: Don't print anything if nothing found soc: qcom: rpmhpd: Use corner in power_off soc: qcom: aoss: Add generic compatible dt-bindings: soc: qcom: aoss: Convert to YAML dt-bindings: soc: qcom: aoss: Add SC8180X and generic compatible firmware: qcom_scm: remove a duplicative condition firmware: qcom_scm: Mark string array const Link: https://lore.kernel.org/r/20210816214840.581244-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The patch be7ecbd240b2: "soc: fsl: qe: convert QE interrupt controller to platform_device" from Aug 3, 2021, leads to the following static checker warning: drivers/soc/fsl/qe/qe_ic.c:438 qe_ic_init() warn: unsigned 'qe_ic->virq_low' is never less than zero. In old variant irq_of_parse_and_map() returns zero if failed so unsigned int for virq_high/virq_low was ok. In new variant platform_get_irq() returns negative error codes if failed so we need to use int for virq_high/virq_low. Also simplify high_handler checking and remove the curly braces to make checkpatch happy.

2021-08-12soc: renesas: Prefer memcpy() over strcpy()Len Baker2-4/+8
strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. So, use memcpy() as a safe replacement. This is a previous step in the path to remove the strcpy() function entirely from the kernel.

The FUSE clock should be enabled during suspend on Tegra124. Currently clk driver enables it on all SoCs, but FUSE may require a higher core voltage on Tegra30 while enabled.

2021-08-11soc: ti: Remove pm_runtime_irq_safe() usage for smartreflexTony Lindgren1-30/+22
For the smartreflex device, we need to disable smartreflex on SoC idle, and have been using pm_runtime_irq_safe() to do that. But we want to remove the irq_safe usage as PM runtime takes a permanent usage count on the parent device with it. In order to remove the need for pm_runtime_irq_safe(), let's gate the clock directly in the driver. This removes the need to call PM runtime during idle, and allows us to switch to using CPU_PM in the following patch. Note that the smartreflex interconnect target module is configured for smart idle, but the clock does not have autoidle capability, and needs to be gated manually. If the clock supported autoidle, we would not need to even gate the clock. With this change, we can now remove the related quirk flags for ti-sysc also.

2021-08-11soc: ti: pruss: Enable support for ICSSG subsystems on K3 AM64x SoCsSuman Anna1-0/+1
The K3 AM64x family of SoCs have a similar version of the PRU-ICSS (ICSSG) processor subsystem present on K3 J721E and K3 AM65x SR2.0 SoCs. These SoCs contain typically two ICSSG instances named ICSSG0 and ICSSG1. The two ICSSGs are identical to each other for the most part with minor SoC integration differences and capabilities. SGMII mode is not supported at all on these SoCs (unlike specific instances on AM65x, J721E). The ICSSG1 also has limited pins connected on some sub-modules compared to ICSSG0. There is no change in the Interrupt Controller w.r.t either of AM65x or J721E SoCs. All other integration aspects are also very similar to the existing SoCs. The existing pruss platform driver has been updated to support these similar ICSSG instances through a new AM64x specific compatible.

Since 5.13 QE's ucc nodes can't get interrupts from devicetree: ucc@2000 { cell-index = <1>; reg = <0x2000 0x200>; interrupts = <32>; interrupt-parent = <&qeic>; }; Now fw_devlink expects driver to create and probe a struct device for interrupt controller. So lets convert this driver to simple platform_device with probe(). Also use platform_get_ and devm_ family function to get/allocate resources and drop unused .compatible = "qeic".
