Subject: [PATCH] gpu: drm: mediatek: correct clk setting AUX_RX_UI_CNT_THR_AUX_FOR_26M
Date: Mon, 18 Aug 2025 16:34:03 +0800 [thread overview]
Message-ID: <20250818083415.1041187-1-payne.lin@mediatek.com> (raw)
From: Bincai Liu <bincai.liu@mediatek.com>
Updated the definition of AUX_RX_UI_CNT_THR_AUX_FOR_26M from 13 to 14.
No other code or logic changes were made; only the macro value was modified.
This change affects the timing configuration for AUX RX at 26MHz.
The formula is xtal_clk / 2 + 1.
