Merge tag 'arm-drivers-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM/SoC driver updates from Arnd Bergmann: "These are updates to SoC specific drivers that did not have another subsystem maintainer tree to go through for some reason: - Some bus and memory drivers for the MIPS P5600 based Baikal-T1 SoC that is getting added through the MIPS tree. - There are new soc_device identification drivers for TI K3, Qualcomm MSM8939 - New reset controller drivers for NXP i.MX8MP, Renesas RZ/G1H, and Hisilicon hi6220 - The SCMI firmware interface can now work across ARM SMC/HVC as a transport. - Mediatek platforms now use a new driver for their "MMSYS" hardware block that controls clocks and some other aspects in behalf of the media and gpu drivers. - Some Tegra processors have improved power management support, including getting woken up by the PMIC and cluster power down during idle. - A new v4l staging driver for Tegra is added. - Cleanups and minor bugfixes for TI, NXP, Hisilicon, Mediatek, and Tegra" * tag 'arm-drivers-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (155 commits) clk: sprd: fix compile-testing bus: bt1-axi: Build the driver into the kernel bus: bt1-apb: Build the driver into the kernel bus: bt1-axi: Use sysfs_streq instead of strncmp bus: bt1-axi: Optimize the return points in the driver bus: bt1-apb: Use sysfs_streq instead of strncmp bus: bt1-apb: Use PTR_ERR_OR_ZERO to return from request-regs method bus: bt1-apb: Fix show/store callback identations bus: bt1-apb: Include linux/io.h dt-bindings: memory: Add Baikal-T1 L2-cache Control Block binding memory: Add Baikal-T1 L2-cache Control Block driver bus: Add Baikal-T1 APB-bus driver bus: Add Baikal-T1 AXI-bus driver dt-bindings: bus: Add Baikal-T1 APB-bus binding dt-bindings: bus: Add Baikal-T1 AXI-bus binding staging: tegra-video: fix V4L2 dependency tee: fix crypto select drivers: soc: ti: knav_qmss_queue: Make knav_gp_range_ops static soc: ti: add k3 platforms chipid module driver dt-bindings: soc: ti: add binding for k3 platforms chipid module ...
