A link to the datasheets and a reference to the "Table ID Definitions"
would be helpful in cross-checking the correctness of the IDs.

The patch doesn't apply cleanly, please rebase on master or next (as
appropriate) for the next revision.

Can't this be included as part of the existing CONFIG_SPI_FLASH_PUYA
which was added by the commit 5c73c05f20be ("mtd: spi-nor-ids: Add Puya
Semiconductor chips description")?
Nit: Would be nice to see new configs being added in alphabetical order
in the Kconfig, though the order is not strictly followed currently :(

Hi Anshul,
Thanks for the review. I have sent v2 with the requested changes (using
existing config and adding datasheet links).
Best regards,
Ssunk
