This patchset is to add common API to configure SAR.
The mechanism is wlan driver registers sar capability
to wiphy and userspace queries it. Userspace then sets
power limiation to wlan driver.

v2:
- rebased on ToT
- fix comments by Johannes and Abhishek
- change sar_power to s32 and range_index to u32

Carl Huang (3):
  nl80211: add common API to configure SAR power limitations.
  mac80211: add ieee80211_set_sar_specs
  ath10k: allow dynamic SAR power limits via common API
