Subject: [PATCH v2 1/2] dt-bindings: pinctrl: qcom: Add sc8280xp TLMM binding
The Qualcomm SC8280XP platform contains a single block of registers
for the TLMM block. This provides pinconf and pinmux for 228 GPIOs, 2
UFS_RESET pins and one SDC interface.
Signed-off-by: Bjorn Andersson <bjorn.andersson@...aro.org>

Changes since v1:
- Dropped $ref: pinctrl.yaml
- Dropped reg-names from required list
- Fixed spelling mistake in example
