Pull ARM SoC driver updates from Arnd Bergmann: "These are all the driver updates for SoC specific drivers. There are a couple of subsystems with individual maintainers picking up their patches here: - The reset controller subsystem add support for a few new SoC variants to existing drivers, along with other minor improvements - The OP-TEE subsystem gets a driver for the ARM FF-A transport - The memory controller subsystem has improvements for Tegra, Mediatek, Renesas, Freescale and Broadcom specific drivers. - The tegra cpuidle driver changes get merged through this tree this time. There are only minor changes, but they depend on other tegra driver updates here. - The ep93xx platform finally moves to using the drivers/clk/ subsystem, moving the code out of arch/arm in the process. This depends on a small sound driver change that is included here as well. - There are some minor updates for Qualcomm and Tegra specific firmware drivers. The other driver updates are mainly for drivers/soc, which contains a mixture of vendor specific drivers that don't really fit elsewhere: - Mediatek drivers gain more support for MT8192, with new support for hw-mutex and mmsys routing, plus support for reset lines in the mmsys driver. - Qualcomm gains a new "sleep stats" driver, and support for the "Generic Packet Router" in the APR driver. - There is a new user interface for routing the UARTS on ASpeed BMCs, something that apparently nobody else has needed so far. - More drivers can now be built as loadable modules, in particular for Broadcom and Samsung platforms. - Lots of improvements to the TI sysc driver for better suspend/resume support" Finally, there are lots of minor cleanups and new device IDs for amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape, allwinner, broadcom, and omap" * tag 'drivers-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (179 commits) optee: Fix spelling mistake "reclain" -> "reclaim" Revert "firmware: qcom: scm: Add support for MC boot address API" qcom: spm: allow compile-testing firmware: arm_ffa: Remove unused 'compat_version' variable soc: samsung: exynos-chipid: add exynosautov9 SoC support firmware: qcom: scm: Don't break compile test on non-ARM platforms soc: qcom: smp2p: Add of_node_put() before goto soc: qcom: apr: Add of_node_put() before return soc: qcom: qcom_stats: Fix client votes offset soc: qcom: rpmhpd: fix sm8350_mxc's peer domain dt-bindings: arm: cpus: Document qcom,msm8916-smp enable-method ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226 firmware: qcom: scm: Add support for MC boot address API soc: qcom: spm: Add 8916 SPM register data dt-bindings: soc: qcom: spm: Document qcom,msm8916-saw2-v3.0-cpu soc: qcom: socinfo: Add PM8150C and SMB2351 models firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available() soc: aspeed: Add UART routing support soc: fsl: dpio: rename the enqueue descriptor variable soc: fsl: dpio: use an explicit NULL instead of 0 ...

dt-bindings: sram: Allow numbers in sram region node name

2021-10-28T12:27:26+00:00

Sram regions node name describes the region of reserved memory and can be names such as l3cache@1000. Permit numbers to be used as part of the reserved memory node name. Signed-off-by: Nishanth Menon Link: https://lore.kernel.org/r/20211012154833.14111-1-nm@ti.com Signed-off-by: Rob Herring

dt-bindings: sram: Document qcom,rpm-msg-ram

2021-10-15T00:57:16+00:00

The Qualcomm SMEM binding always depended on a reference to a SRAM node of compatible "qcom,rpm-msg-ram", document this as part of the SRAM binding. The SRAM is consumed as a whole and not split up using subnodes, so properties related to this are not required.

"amlogic,meson-gxbb-scp-shmem" is already in the Generic on-chip SRAM binding though "amlogic,meson-gxbb-scpi" is missing which is now added. Also remove the whole old text format binding for the same.

Commit a90b15e0ad72 ("Documentation: bindings: decouple juno specific details from generic binding") moved the juno specific bindings into separate file. Though there was no need for juno specific binding, it has been used unfortunately for whatever stupid reason I added it for. Let us move the same to the generic sram.yaml schema and remove the old text format binding.
