Subject: [PATCH 5/6] spi: spi-fsl-dspi: Support SPI software timestamping in all non-DMA modes
Date: Mon, 2 Mar 2020 02:19:57 +0200 [thread overview]
Message-ID: <20200302001958.11105-6-olteanv@gmail.com> (raw)
In-Reply-To: <20200302001958.11105-1-olteanv@gmail.com>
From: Vladimir Oltean <vladimir.oltean@nxp.com>
There's no reason to keep this .ptp_sts_supported property explicitly in
devtype_data, since it can be deduced from the operating mode alone.
