Subject: [EXT] [PATCH] spi: nxp-fspi: Ensure width is respected in
spi-mem
operations
Caution: EXT Email
Make use of a core helper to ensure the desired width is respected
when
calling spi-mem operators.
Otherwise only the SPI controller will be matched with the flash chip,
which
might lead to wrong widths. Also consider the width specified by the
user in
the device tree.
Could you please mention the flash and modes you tested. Does it
support DUAL/QUAD mode?
I couldn't test these modes as NXP LS1028ARDB has "mt35xu02g" which
supports SINGLE and OCTAL modes only.
That commit is already upstream. But FWIW, it was a Winbond W25Q32FW in
dual i/o mode.
