Subject: Re: [PATCH 6.12.y] spi: spi-fsl-dspi: Avoid setup_accel logic for DMA transfers
Date: Tue, 11 Aug 2026 11:13:21 +0200	[thread overview]
Message-ID: <20260811091322.3592403-1-mehmet.fide@gmail.com> (raw)
In-Reply-To: <20260811084018.3566861-1-mehmet.fide@gmail.com>

Thanks, that fits what we see. Larisa is on cc, so she may remember whether it
started as a fix in the NXP branch.

Either way the behaviour is the same. On vf610 in DMA mode the accel path drops
the tail of odd length transfers and byte swaps under SPI_LSB_FIRST, and this
commit removes both. That is what makes it worth having in 6.12.y, whatever the
original intent was.

Thanks,
Mehmet
