[PATCH v3 00/32] mtd: spi-nor: move vendor specific code into vendor modules

From: Michael Walle
Date: Mon Feb 21 2022 - 03:53:51 EST


It turns out that most of the special status register handling is
specific for a particular vendor. I.e. Xilinx has some different
opcodes for the status register read, Micron has an additional FSR
register and Spansion has these flags integrated into the SR.

Create a callback to ready() where a flash chip can register its
own function. This will let us move all the vendor specific stuff
out of the core into the vendor modules.

As a preparation step, unify all function and object names in the
vendor modules. For the sake of consistency and better readability
of the code flow, I also converted the setup() callback to be
optional.

Please note that this is only compile-time tested.

Changes since v2:
- use family_nor_ instead of just family_ prefix
- fix function doc

Changes since v1:
- rename/unify function names inside the vendor modules.
- make local functions static
- fix function doc typo
- use late_init hook to set fsr_ready op
- Use uppercase and period in comments
- Add comments for the vendor flags
- move coding style change in spi_nor_sr_ready() into own patch
- new patch to add missing parenthesis in S3AN_INFO()
- add missing function prefix rename patch for the spansion module
