Subject: [PATCH v3 1/2] spi: dt-bindings: mediatek,spi-mt65xx: add MT7987/MT7989 compatibles
Date: Thu, 8 Oct 2026 16:53:31 +0800 [thread overview]
Message-ID: <20261008085332.802898-1-Tim.Kuo@mediatek.com> (raw)
The MT7987 and MT7989 SPI IPs are IPM designs, so they keep
"mediatek,spi-ipm" as their fallback compatible, but they widen the tick
delay field of SPI_CMD_REG and therefore need compatibles of their own.
Signed-off-by: Tim Kuo <Tim.Kuo@mediatek.com>
---
v2: Add mt7987 and mt7989 real device compatible
v3:
- Drop "mediatek,spi-ipm-v59"
- Move compatible of mt7987 and mt7989 to group of spi-ipm fallback
