From eb4fdb4bf46f875eac3c093f7ff43a223985f7b8 Mon Sep 17 00:00:00 2001 From: Théo Lebrun Date: Wed, 10 Apr 2024 11:29:06 +0200 Subject: spi: dt-bindings: cdns,qspi-nor: make cdns,fifo-depth optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
