Was this sent upstream to the Linux kernel already? I did a very quick
search on lore.kernel.org and didn't find anything. Is there anything
that's preventing you from sending this to them first? I really would
prefer to have only U-Boot specific stuff in -u-boot.dtsi DTSIs.
no, not yet, but I'll send this to Linux ASAP.
since SPI NOR flash is used for U-Boot, I sent this to here first.
Best regards,
