Subject: [PATCH 21/59] drm/kmb: IRQ handlers for LCD and mipi dsi
Date: Tue, 30 Jun 2020 14:27:33 -0700 [thread overview]
Message-ID: <1593552491-23698-22-git-send-email-anitha.chrisanthus@intel.com> (raw)
In-Reply-To: <1593552491-23698-1-git-send-email-anitha.chrisanthus@intel.com>
Added handlers for lcd and mipi, it only finds and clears the interrupt
as of now, more functionality can be added as needed.
