Subject: spi: nxp_fspi: Support i.MX8ULP flexspi
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=320b191ec820705f24ab7f7981dc3b60ab9e0ee8;p=pandora-u-boot.git

spi: nxp_fspi: Support i.MX8ULP flexspi

Add i.MX8ULP flexspi compatible string and driver data.
The flexspi on i.MX8ULP only has 16 LUT sequences and uses 1KB RX FIFO.
