Subject: [PATCH v2 1/8] drm/bridge: synopsis: Add mode_fixup and bridge timings support
Date: Thu, 5 Aug 2021 16:07:50 +0200 [thread overview]
Message-ID: <15187eccabf39561de226acd8be40b93503cac49.1628172477.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1628172477.git.hns@goldelico.com>
From: Paul Boddie <paul@boddie.org.uk>
The platform-specific configuration structure is augmented with
mode_fixup and timings members so that specialisations of the
Synopsys driver can introduce mode flags and bus flags.
