On Google Tensor gs101 there are separate bus clocks / gates each for each pinctrl instance. To be able to access each pinctrl instance's registers, this bus clock needs to be running, otherwise register access will hang. The driver update to support this extra clock has been proposed in https://lore.kernel.org/r/20240426-samsung-pinctrl-busclock-v3-0-adb8664b8a7e@linaro.org This series depends on: * hsi2 series: https://lore.kernel.org/r/20240429-hsi0-gs101-v3-0-f233be0a2455@linaro.org * pin controller clock support: https://lore.kernel.org/r/20240426-samsung-pinctrl-busclock-v3-0-adb8664b8a7e@linaro.org Signed-off-by: André Draszik --- André Draszik (4): arm64: dts: exynos: gs101: specify bus clock for pinctrl (far) alive arm64: dts: exynos: gs101: specify bus clock for pinctrl_peric[01] arm64: dts: exynos: gs101: specify bus clock for pinctrl_hsi2 arm64: dts: exynos: gs101: specify placeholder clocks for remaining pinctrl arch/arm64/boot/dts/exynos/google/gs101.dtsi | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) --- base-commit: 87e0588641086e91f3d0a7d97b939301990b1e86 change-id: 20240429-samsung-pinctrl-busclock-dts-46b223471541 Best regards,
