Subject: [PATCH v2 1/2] spi: dt-bindings: add SPI IPM v59 compatible for mt7987 and mt7989
Date: Tue, 29 Sep 2026 14:25:15 +0800 [thread overview]
Message-ID: <20260929062516.416368-1-Tim.Kuo@mediatek.com> (raw)
MTK mt7987 and mt7989 SPI hardware has been updated to IPM v59 SPI IP and
it differs from earlier IPM designs, most visibly in the tick delay field
of SPI_CMD_REG, so it needs its own fallback compatible rather than reusing
"mediatek,spi-ipm".
