Subject: [Intel-gfx] [PATCH v2 02/50] drm/i915/xelpd: Handle proper AUX interrupt bits
Date: Thu, 25 Mar 2021 11:06:32 -0700	[thread overview]
Message-ID: <20210325180720.401410-3-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210325180720.401410-1-matthew.d.roper@intel.com>

XE_LPD has new AUX interrupt bits for DDI-D and DDI-E that take the
spots that were used by TC5/TC6 on Display12 platforms.

While we're at it, let's convert the bit definitions for all TGL+ aux
bits over to the modern REG_BIT() notation.

v2:
 - Maintain bit order rather than logical order.  (Lucas)
 - Convert surrounding code to REG_BIT() notation.  (Lucas)
