Subject: [PATCH 0/2] spi: spi-fsl-qspi: support setting sampling delay through devicetree
Date: Mon, 16 Jan 2023 12:50:48 +0100 [thread overview]
Message-ID: <20230116115050.2983406-1-dev@kicherer.org> (raw)
The internal sampling point of incoming data can be delayed by modifying
the QuadSPI_SMPR register. This patch enables setting this delay using a
device tree entry.
