Subject: [PATCH v2 2/2] drm/panel: ilitek-ili9881c: Add configuration for 5" Raspberry Pi 720x1280
Date: Thu, 4 Sep 2025 22:56:57 +0200 [thread overview]
Message-ID: <20250904205743.186177-2-marek.vasut+renesas@mailbox.org> (raw)
In-Reply-To: <20250904205743.186177-1-marek.vasut+renesas@mailbox.org>
Add configuration for the 5" Raspberry Pi 720x1280 DSI panel
based on ili9881. This uses 10px longer horizontal sync pulse
and 10px shorter HBP to avoid very short hsync pulse.
