Subject: [Intel-gfx] [PATCH 2/9] drm/i915/mtl: Create separate reg file for PICA registers
Date: Thu, 13 Apr 2023 14:24:36 -0700	[thread overview]
Message-ID: <20230413212443.1504245-3-radhakrishna.sripada@intel.com> (raw)
In-Reply-To: <20230413212443.1504245-1-radhakrishna.sripada@intel.com>

From: Mika Kahola <mika.kahola@intel.com>

Create a separate file to store registers for PICA chips
C10 and C20.

v2: Rename file (Jani)
v3: Use _PICK_EVEN_2RANGES() macro (Lucas)
    Coding style fixed (Lucas)
v4: Redefine macros (Imre)
