Subject: [PATCH 1/2] dt-bindings: spi: mediatek: add mediatek,spi-ipm-v59 compatible
Date: Thu, 24 Sep 2026 11:12:10 +0800 [thread overview]
Message-ID: <20260924031211.2199921-1-Tim.Kuo@mediatek.com> (raw)
The IPM v59 SPI IP 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".
