Reasons

1. driver up
2. watchdog
3. phy init
4. bss join
5. ibss join
6. start bss

phy init

1. if multi phase allowed and pending:
   1. reset multie phase
   2. schedule multi phase calibration for later

(i)bss join, start bss

1. if multi phase allowed and pending, reset multi phase
2. run full

watchdog

1. if multi phase allowed and not pending, schedule multi phase
2. run auto

reset multi phase

multi phase calibration

run

• do nothing if channel is muted (radar)
• if channel is quiet, do only after associated
• if doing auto, fall back to full unless last calibration was on the current channel
• restart multi phase if it was started and previously on a different channel
• suspend MAC
• enter PHY reg lock
• if multi phase is idle or in step 0,
  • store bits 0x7f00 from phy regs 0x1ed and 0x1ee
  • if tx power control is off, read table ..., otherwise use values 0 and 0
• get target TX gain
• set TX power control to off

• ... FIXME on rev >= 3

• if antenna selection is 2x3, init superswitch (1)
• ... multi phase stuff ...

• ... restore FIXME on rev >= 3

• set TX power control to previous state
• exit PHY reg lock, enable MAC
