Subject: [PATCH v6 5/6] drm/verisilicon: add DCUltraLite chip identity to HWDB
Date: Tue, 8 Sep 2026 17:28:39 +0800 [thread overview]
Message-ID: <20260908092840.225220-6-a0987203069@gmail.com> (raw)
In-Reply-To: <20260908092840.225220-1-a0987203069@gmail.com>
The Nuvoton MA35D1 chip contains a DCUltraLite display controller with
model number 0x0 (sic, the model name contains no number either),
revision 0x5560 and customer ID 0x305. It has a similar register map
with DC8000, only one display output and only 32x32 cursor supported.
