From 2f2b1a84fc141575eeabfacbd7c35af0b5dbb0b9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 29 Jul 2026 07:27:26 -0600 Subject: [PATCH] dt-bindings: gpio: rockchip,gpio-bank: Add rockchip,grf property Some Rockchip SoCs, such as the RV1106, give each GPIO bank its own IO control (IOC) register block rather than grouping the registers of all banks into a shared GRF region. Add an optional rockchip,grf property to the gpio-bank binding so that each bank node can reference the syscon for its own IOC block.
