Subject: [PATCH] arm64: dts: amlogic: a4: fix dtb compilation warning
issues
From: Xianwei Zhao <xianwei.zhao@...ogic.com>
When use command 'make ARCH=arm64 dtbs_check W=1' to compile dtb,
a warning message appears.
"Warning (simple_bus_reg): /soc/bus@...00000/pinctrl:
missing or empty reg/ranges property"
Add the unit address to the pinctrl node to fix it.
Fixes: ce78f679e08c ("arm64: dts: amlogic: a4: add pinctrl node")
