Pull ARM SoC driver updates from Arnd Bergmann: "A couple of subsystems have their own subsystem maintainers but choose to have the code merged through the soc tree as upstream, as the code tends to be used across multiple SoCs or has SoC specific drivers itself: - memory controllers: Krzysztof Kozlowski takes ownership of the drivers/memory subsystem and its drivers, starting out with a set of cleanup patches. A larger driver for the Tegra memory controller that was accidentally missed for v5.8 is now added. - reset controllers: Only minor updates to drivers/reset this time - firmware: The "turris mox" firmware driver gains support for signed firmware blobs The tegra firmware driver gets extended to export some debug information Various updates to i.MX firmware drivers, mostly cosmetic - ARM SCMI/SCPI: A new mechanism for platform notifications is added, among a number of minor changes. - optee: Probing of the TEE bus is rewritten to better support detection of devices that depend on the tee-supplicant user space. A new firmware based trusted platform module (fTPM) driver is added based on OP-TEE - SoC attributes: A new driver is added to provide a generic soc_device for identifying a machine through the SMCCC ARCH_SOC_ID firmware interface rather than by probing SoC family specific registers. The series also contains some cleanups to the common soc_device code. There are also a number of updates to SoC specific drivers, the main ones are: - Mediatek cmdq driver gains a few in-kernel interfaces - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding support for additional SoC variants - The Qualcomm GENI core code gains interconnect path voting and performance level support, and integrating this into a number of device drivers. - A new driver for Samsung Exynos5800 voltage coupler for - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC specific device drivers - Updates to the TI K3 Ring Accelerator driver" * tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (164 commits) soc: qcom: geni: Fix unused label warning soc: qcom: smd-rpm: Fix kerneldoc memory: jz4780_nemc: Only request IO memory the driver will use soc: qcom: pdr: Reorder the PD state indication ack MAINTAINERS: Add Git repository for memory controller drivers memory: brcmstb_dpfe: Fix language typo memory: samsung: exynos5422-dmc: Correct white space issues memory: samsung: exynos-srom: Correct alignment memory: pl172: Enclose macro argument usage in parenthesis memory: of: Correct kerneldoc memory: omap-gpmc: Fix language typo memory: omap-gpmc: Correct white space issues memory: omap-gpmc: Use 'unsigned int' for consistency memory: omap-gpmc: Enclose macro argument usage in parenthesis memory: omap-gpmc: Correct kerneldoc memory: mvebu-devbus: Align with open parenthesis memory: mvebu-devbus: Add missing braces to all arms of if statement memory: bt1-l2-ctl: Add blank lines after declarations soc: TI knav_qmss: make symbol 'knav_acc_range_ops' static firmware: ti_sci: Replace HTTP links with HTTPS ones ...

soc: imx: select ARM_GIC_V3 for i.MX8M

Select ARM_GIC_V3, then it is able to use gic v3 driver in aarch32 mode linux on aarch64 hardware. For aarch64 mode, it not hurts to select ARM_GIC_V3. Acked-by: Arnd Bergmann Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

fsl,ls1021a is a mach under arch/arm/mach-imx/, however it could not use the soc driver which will break caam on ls1021a platform. So directly return if it is compatible with fsl,ls1021a.

firmware: imx: Move i.MX SCU soc driver into imx firmware folder

2020-07-13T02:02:00+00:00

The i.MX SCU soc driver depends on SCU firmware driver, so it has to use platform driver model for proper defer probe operation, since it has no device binding in DT file, a simple platform device is created together inside the platform driver. To make it more clean, we can just move the entire SCU soc driver into imx firmware folder and initialized by i.MX SCU firmware driver. Signed-off-by: Anson Huang Signed-off-by: Shawn Guo
