[PATCH v2 0/3] spi: amd: Add support for new controller version

[PATCH v2 0/3] spi: amd: Add support for new controller version

[André Almeida]

This series do some cleanup and add support for new controller version,
AMDI0062.

Change from v1:
- Replace `if (version == 2)` with a more extensible switch case.

André Almeida (3):
  spi: amd: Use iopoll for busy waiting
  spi: amd: Remove needless rom_addr variable
  spi: amd: Add support for version AMDI0062

[PATCH v2 1/3] spi: amd: Use iopoll for busy waiting

[André Almeida]

Instead of implementing a custom IO busy wait function, just use
readl_poll_timeout().

[PATCH v2 2/3] spi: amd: Remove needless rom_addr variable

[André Almeida]

rom_addr is not used in the code, so we can just drop it from struct
amd_spi.

[André Almeida]

Add support for the AMD SPI controller version AMDI0062. Do this in a
modular way where's easy to add new versions.
