The manufacturer may be optional when pure SFDP flashes are supported. Hide the sysfs property if no manufacturer is set.

2022-11-21mtd: spi-nor: hide jedec_id sysfs attribute if not presentMichael Walle1-0/+3
Some non-jedec compliant flashes (like the Everspin flashes) don't have an ID at all. Hide the attribute in this case.

Add support to show the manufacturer, the partname and JEDEC identifier as well as to dump the SFDP table. Not all flashes list their SFDP table contents in their datasheet. So having that is useful. It might also be helpful in bug reports from users. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Acked-by: Pratyush Yadav <p.yadav@ti.com>
