Subject: [PATCH 1/2] dt-bindings: pinctl: amlogic,pinctrl-a4: Add
 compatible string for A5

From: Xianwei Zhao <xianwei.zhao@...ogic.com>

Amlogic A5 SoCs uses the same pintrl controller as A4 SoCs. There is
no need for an extra compatible line in the driver, but add A5
compatible line for documentation.
