Subject: [PATCH v3 3/9] spi: dt-bindings: cdns,qspi-nor: make cdns,fifo-depth optional
Date: Wed, 10 Apr 2024 11:29:06 +0200 [thread overview]
Message-ID: <20240410-cdns-qspi-mbly-v3-3-7b7053449cf7@bootlin.com> (raw)
In-Reply-To: <20240410-cdns-qspi-mbly-v3-0-7b7053449cf7@bootlin.com>
Make cdns,fifo-depth devicetree property optional.
Value can be detected at runtime.
Upper SRAMPARTITION register bits are read-only. Procedure to find FIFO
depth is therefore to write 0xFFFFFFFF and read back to get amount of
writeable bits.
