Subject: pinctrl: amd: Add Z-state wake control bits
From: Basavaraj Natikar <Basavaraj.Natikar@xxxxxxx>
commit df72b4a692b60d3e5d99d9ef662b2d03c44bb9c0 upstream.
GPIO registers include Bit 27 for WakeCntrlZ used to enable wake in
Z state. Hence add Z-state wake control bits to debugfs output to
debug and analyze Z-states problems.
