Subject: [PATCH 0/3] Rewrite MediaTek UART APDMA driver to support more than 33 bits
Date: Sun, 21 Sep 2025 14:03:39 +0300 [thread overview]
Message-ID: <20250921-uart-apdma-v1-0-107543c7102c@proton.me> (raw)
This patch series aims to support more than 33 bits for the MediaTek
APDMA driver, since newer SoCs like MT6795, MT6779 or MT6985 have higher
values for the DMA bitmask.
The reference SoCs for bitmask values were taken from the downstream
kernel (6.6) for the MT6991 SoC.
