Subject: [PATCH AUTOSEL 5.13 099/219] arm64: dts: qcom: sdm630: Fix TLMM node and pinctrl configuration
From: AngeloGioacchino Del Regno <angelogioacchino.delregno@...ainline.org>
[ Upstream commit 36a0d47aee6a8cfd3c6cf4274732d8ef994a25b4 ]
Previous pinctrl configuration was wrong. Fix it and clean up how
multi-pin states are described.
