[PATCHv2 0/3] wifi: ath9k: remove platform_data support

[Rosen Penev]

This series removes platform_data support as it's deprecated, unused,
and replaced by OF.

v2: just remove platform data.

[PATCHv2 1/3] wifi: ath9k: eeprom: remove platform data

[Rosen Penev]

There are no more board files defining platform data for this driver and
eeprom support through NVMEM has already been implemented. No need to
keep this old functionality around.

[PATCHv2 2/3] wifi: ath9k: btcoex: remove platform_data

[Rosen Penev]

This is completely unused as platform files are no longer used anywhere.

[PATCHv2 3/3] wifi: ath9k: remove ath9k_platform_data

[Rosen Penev]

Completely unused here in favor of Device Tree based setup. The DT code
in here should currently match what is available with platform files.
Any such lapse can always be added.
