Subject: [PATCH v9 2/3] dt-bindings: mfd: Add compatible string for UART support
From: Bhanu Prakash Maiya <bhanumaiya@...omium.org>
Add a compatible string to support the UART implementation of the cros
ec interface. The driver does not support the reg and interrupt
properties, so exempt them from being required for UART compatible nodes.
