[ath9k-devel] [PATCH 0/4] ath9k_hw: modify hw identification message

[ath9k-devel] [PATCH 0/4] ath9k_hw: modify hw identification message

[Luis R. Rodriguez]

While reviewing ar9271 radio revisions I determined the radio revision
does not apply although it can be populated in the EEPROM. This changes
the hw probe print to reflect this for single chips and throws the code
into hw code to be shared with ath9k_htc.

Luis R. Rodriguez (4):
  ath9k_hw: move mac name and rf name helpers to hw code
  ath9k_hw: distinguish single-chip solutions on initial probe print
  ath9k_hw: add AR9271 single chip name mapping
  ath9k_hw: add some debug print for hw initialization

[ath9k-devel] [PATCH 2/4] ath9k_hw: distinguish single-chip solutions on initial probe print

[Luis R. Rodriguez]

Devices with external radios have revisions which we can count on.
On single chip solutions these EEPROM values for these radio revision
also exist but are not meaningful as the radios are embedded onto the
same chip. Each single-chip device evolves together as one device.

[PATCH 2/4] ath9k_hw: distinguish single-chip solutions on initial probe print

[Luis R. Rodriguez]

Devices with external radios have revisions which we can count on.
On single chip solutions these EEPROM values for these radio revision
also exist but are not meaningful as the radios are embedded onto the
same chip. Each single-chip device evolves together as one device.

We use this for debugfs, so I went with that as an upper limit, given
that we just use it a probe it seemed sane.

I think it's completely insane, because you effectively use 25% of the available stack.
Why is a hardware name 1024 chars (max) long anyway?

I would be pissed off after reading the first line already ;)
