Subject: Claude review: drm/tidss: Add external data and sync signal edge configuration
Date: Thu, 23 Apr 2026 09:45:59 +1000 [thread overview]
Message-ID: <review-patch9-20260420-beagley-ai-display-v1-9-f628543dfd14@ideasonboard.com> (raw)
In-Reply-To: <20260420-beagley-ai-display-v1-9-f628543dfd14@ideasonboard.com>
Patch Review
The DPI0_CLK_CTRL register programming logic looks correct: `DPI0_CLK_CTRL_DATA_CLK_INVDIS` disables data clock inversion (i.e., set when data should be driven on rising edge, matching `!ipc`), and `DPI0_CLK_CTRL_SYNC_CLK_INVDIS` disables sync clock inversion (set when sync is on rising edge, matching `rf`).
**Issue — `syscon_regmap_lookup_by_compatible()`:** This does a global search for any node with `compatible = "ti,am625-dss-dpi0-clk-ctrl"`. On AM62P with two DSS instances sharing one DPI0_CLK_CTRL register, this works by coincidence. But the usual kernel pattern is `syscon_regmap_lookup_by_phandle()` referencing a phandle property in the DSS node (like the existing `ti,oldi-io-ctrl` pattern for OLDI). The error message even says "syscon_regmap_lookup_by_phandle failed" which is misleading since it's actually a by-compatible lookup. Consider switching to a phandle-based lookup (and adding the property to the DT binding).
