Pull SoC driver updates from Arnd Bergmann: "This is the first half of the driver changes: - A treewide interface change to the "syscore" operations for power management, as a preparation for future Tegra specific changes - Reset controller updates with added drivers for LAN969x, eic770 and RZ/G3S SoCs - Protection of system controller registers on Renesas and Google SoCs, to prevent trivially triggering a system crash from e.g. debugfs access - soc_device identification updates on Nvidia, Exynos and Mediatek - debugfs support in the ST STM32 firewall driver - Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI - Cleanups for memory controller support on Nvidia and Renesas" * tag 'soc-drivers-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (114 commits) memory: tegra186-emc: Fix missing put_bpmp Documentation: reset: Remove reset_controller_add_lookup() reset: fix BIT macro reference reset: rzg2l-usbphy-ctrl: Fix a NULL vs IS_ERR() bug in probe reset: th1520: Support reset controllers in more subsystems reset: th1520: Prepare for supporting multiple controllers dt-bindings: reset: thead,th1520-reset: Add controllers for more subsys dt-bindings: reset: thead,th1520-reset: Remove non-VO-subsystem resets reset: remove legacy reset lookup code clk: davinci: psc: drop unused reset lookup reset: rzg2l-usbphy-ctrl: Add support for RZ/G3S SoC reset: rzg2l-usbphy-ctrl: Add support for USB PWRRDY dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/G3S support reset: eswin: Add eic7700 reset driver dt-bindings: reset: eswin: Documentation for eic7700 SoC reset: sparx5: add LAN969x support dt-bindings: reset: microchip: Add LAN969x support soc: rockchip: grf: Add select correct PWM implementation on RK3368 soc/tegra: pmc: Add USB wake events for Tegra234 amba: tegra-ahb: Fix device leak on SMMU enable ...

dt-bindings: reset: thead,th1520-reset: Add controllers for more subsys

2025-11-18T16:52:54+00:00

TH1520 SoC is divided into several subsystems, most of them have distinct reset controllers. Let's document reset controllers other than the one for VO subsystem and IDs for their reset signals.

dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/G3S support

2025-11-18T16:52:54+00:00

The Renesas USB PHY hardware block needs to have the PWRRDY bit in the system controller set before applying any other settings. The PWRRDY bit must be controlled during power-on, power-off, and system suspend/resume sequences as follows: - during power-on/resume, it must be set to zero before enabling clocks and modules - during power-off/suspend, it must be set to one after disabling clocks and modules Add the renesas,sysc-pwrrdy device tree property, which allows the reset-rzg2l-usbphy-ctrl driver to parse, map, and control the system controller PWRRDY bit at the appropriate time. Along with it add a new compatible for the RZ/G3S SoC. Reviewed-by: Rob Herring (Arm) Signed-off-by: Claudiu Beznea Signed-off-by: Philipp Zabel

Generally at most 1 blank line is the standard style for DT schema files. Remove the few cases with more than 1 so that the yamllint check for this can be enabled.

2025-06-27T16:12:30+00:00

Document support for the USB2PHY reset controller found on the Renesas RZ/V2N (R9A09G056) SoC. The reset controller IP is functionally identical to that on the RZ/V2H(P) SoC, so no driver changes are needed. The existing `renesas,r9a09g057-usb2phy-reset` compatible will be used as a fallback for the RZ/V2N SoC.
