Subject: Claude review: drm: bridge: dw_hdmi: Disable scrambler feature when not supported
Date: Tue, 05 May 2026 07:58:54 +1000 [thread overview]
Message-ID: <review-patch1-20260504191059.275928-2-jonas@kwiboo.se> (raw)
In-Reply-To: <20260504191059.275928-2-jonas@kwiboo.se>
Patch Review
Straightforward fix. When the SCDC path is not taken (because scrambling is not needed or supported), the scrambler control register is explicitly cleared. This handles the hotplug scenario described in the commit message correctly.
```c
+ } else if (hdmi->version >= 0x200a) {
+ hdmi_writeb(hdmi, 0, HDMI_FC_SCRAMBLER_CTRL);
}
```
The version check `>= 0x200a` is consistent with how the existing code gates SCDC features. Looks correct. Has Reviewed-by.
