Subject: [PATCH 1/2] drm/i915: Bump skl+ wm blocks to 11 bits
Date: Tue,  5 Feb 2019 22:50:55 +0200	[thread overview]
Message-ID: <20190205205056.30081-1-ville.syrjala@linux.intel.com> (raw)

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

On icl the plane watermark blocks field is 11 bits. Bump our define to
match so that readout won't ignore the extra bit. We can safely do this
for older platforms too since the unused bits are hardwired to zero.
