Subject: [PATCH 04/17] drm/msm/dpu: Add support for DPU 12.1 on Nord
Date: Fri, 11 Sep 2026 21:06:35 +0530	[thread overview]
Message-ID: <20260911-nord-drv-dt-v1-4-e25c073cf1b6@oss.qualcomm.com> (raw)
In-Reply-To: <20260911-nord-drv-dt-v1-0-e25c073cf1b6@oss.qualcomm.com>

From: Mahadevan P <mahadevan.p@oss.qualcomm.com>

Add the DPU catalog entry for the Qualcomm Nord SoC (MDSS 12.1, DPU
1499A). Nord is DP-only with no DSI, and provides 8 DSPP blocks, 2
writeback blocks, 8 interfaces and 2 DP controllers.

Extend enum dpu_intf with INTF_9 and INTF_10, which Nord is the first
platform to use.

Note: register addresses and xin_id values in the catalog are borrowed
from sm8750 and precedent platforms and are marked with FIXME(REG_ADDR)
and FIXME(XIU_MAP); they need verification against a real Nord register
map before production use.
