From: Jonas Karlman Date: Tue, 5 May 2026 17:04:06 +0000 (+0200) Subject: dt-bindings: phy: rockchip,inno-usb2phy: Require GRF for RK3568/RV1108 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a896852613136e6babe6036567ab0989fb322a57;p=thirdparty%2Fkernel%2Fstable.git dt-bindings: phy: rockchip,inno-usb2phy: Require GRF for RK3568/RV1108 Typically these Rockchip USB2 PHYs are fully contained within a single GRF. However, for RK3568 and RV1108 regs to control the USB2 PHY is located in a different GRF compared to the base address. Update this binding to require rockchip,usbgrf for RK3568 and RV1108 to properly reflect that the USB GRF is required to control the USB2 PHYs on these variants. Also disable use of rockchip,usbgrf for variants where it is not required. This should not introduce any breakage as the affected usb2phy nodes for RK3568 and RV1108 were added together with a rockchip,usbgrf phandle in their initial commit.
