Pull remoteproc updates from Bjorn Andersson: "This fixes a race condition in the user space interface for starting and stopping remote processors, it makes the ELF loader properly skip zero memsz segments and it cleans up the debugfs tracefile code a bit by not checking for errors. It introduces support for controlling the audio DSP on Qualcomm MSM8226, as well as audio and compute DSPs on Qualcomm SC8280XP. It makes it possible to specify the firmware path for Mediatek's remote processors, fixes a double free in the SCP driver and addresses an issue with the SRAM initialization on MT8195. Lastly it deprecates the custom ELF loader in the iMX remoteproc driver, in favor of using the shared one" * tag 'rproc-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (21 commits) dt-bindings: remoteproc: mediatek: Add optional memory-region to mtk,scp dt-bindings: remoteproc: mediatek: Make l1tcm reg exclusive to mt819x dt-bindings: remoteproc: st,stm32-rproc: Fix phandle-array parameters description remoteproc: imx_rproc: Support i.MX93 dt-bindings: remoteproc: imx_rproc: Support i.MX93 remoteproc: qcom: pas: Add MSM8226 ADSP support dt-bindings: remoteproc: qcom: pas: Add MSM8226 adsp remoteproc: mediatek: Allow reading firmware-name from DT dt-bindings: remoteproc: mediatek: Add firmware-name property remoteproc: qcom: pas: Add sc8280xp remoteprocs dt-bindings: remoteproc: qcom: pas: Add sc8280xp adsp and nsp pair dt-bindings: remoteproc: mediatek: Add interrupts property to mtk,scp remoteproc: imx_rproc: Ignore create mem entry for resource table remoteproc: core: Move state checking to remoteproc_core remoteproc: core: Remove state checking before calling rproc_boot() remoteproc: imx_dsp_rproc: Make rsc_table optional remoteproc: imx_dsp_rproc: use common rproc_elf_load_segments remoteproc: elf_loader: skip segment with memsz as zero remoteproc: mtk_scp: Fix a potential double free remoteproc: Don't bother checking the return value of debugfs_create* ...

dt-bindings: remoteproc: mediatek: Add optional memory-region to mtk,scp

2022-05-17T02:19:08Z

The SCP co-processor can optionally be passed a reserved memory region to use. Add this property in the dt-binding. Signed-off-by: Nícolas F. R. A.

dt-bindings: remoteproc: mediatek: Make l1tcm reg exclusive to mt819x

2022-05-17T02:17:10Z

Commit ca23ecfdbd44 ("remoteproc/mediatek: support L1TCM") added support for the l1tcm memory region on the MT8192 SCP, adding a new da_to_va callback that handles l1tcm while keeping the old one for back-compatibility with MT8183. However, since the mt8192 compatible was missing from the dt-binding, the accompanying dt-binding commit 503c64cc42f1 ("dt-bindings: remoteproc: mediatek: add L1TCM memory region") mistakenly added this reg as if it were for mt8183. And later it became common to all platforms as their compatibles were added. Fix the dt-binding so that the l1tcm reg can be present only on the supported platforms: mt8192 and mt8195.

Merge tag 'qcom-drivers-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers

2022-05-09T21:14:06Z

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 ...
