This series is four of a set of five to add support for wcn3680 at 802.11ac
data-rates.

In this set we add the ability to configure up the wcn3680 PHY to get onto
80MHz channels. To do that, the upper unused bits of the hw_value field of
the struct ieee80211_channel are used to encode additional PHY settings.

Accessor macros are provided to encode and decode this additional
information. Depending on which channel we are on, we need to configure the
PHY into one of four modes representing four potential adjacent 20MHz
channels.

The modes describe where the primary channel sits in relation to the other
three channels giving us 20MHz + 20MHz + 20MHz + 20MHz to get 80MHz.

Bryan O'Donoghue (5):
  wcn36xx: Add accessor macro HW_VALUE_CHANNEL for hardware channels
  wcn36xx: Use HW_VALUE_CHANNEL macro to get channel number
  wcn36xx: Add accessor macro HW_VALUE_PHY for PHY settings
  wcn36xx: Encode PHY mode for 80MHz channel in hw_value
  wcn36xx: Set PHY into correct mode for 80MHz channel width
