[PATCH v5 0/4] wcn36xx: Update firmware config to support wcn3680

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

This series is about providing a parameters to firmware to get us up onto
802.11ac data-rates finally.

Once the firmware config is provided to the chip and VHT parameters are
populated we are good to go in terms of the higher data-rate for the
wcn3680.

I get typical data-rates of:

[ ID] Interval           Transfer     Bitrate         Retr
[  5]   0.00-320.00 sec  4.93 GBytes   132 Mbits/sec  445     sender
[  5]   0.00-320.14 sec  4.93 GBytes   132 Mbits/sec          receiver

Downstream 3.10 prima is getting I'm told 180-200 Mbits/sec on the same
hardware so with time and effort there's certainly some performance gain to
be squeezed out of this silicon yet.

However as a first pass, I believe this is good enough and useful enough to
others to submit for upstream inclusion.

An interesting project and a medium term goal would be to have a unified
configuration for all three supported chipsets.

For now suggesting a separate firmware configuration to make sure the
existing lower-speed 802.11n and higher-speed 802.11ac chips don't step on
each other's toes vis-a-vis firmware parameters.

V5:
- No change to V4 but need to send the set again so that
  prerequisite-patch-id makes sense to the build robot here.

V4:
- No functional change.
  Sending out full set again using --base=ath-202009090652 to aid kernel
  test robot

V3:
No difference between V3 and V2 below
https://lore.kernel.org/linux-wireless/20200829034002.2167878-1-bryan.odonoghue@linaro.org/T/#t

V2:
- Sets the default data-rate for wcn3680 to MCS8
- Zapps a few firmware settings for power-saving
  Powersave configuration as a specific wcn3680 topic is WIP on my end
  and I think therefore better left out of an intiial submission.

Bryan O'Donoghue (4):
  wcn36xx: Extend HAL param config list
  wcn36xx: Define wcn3680 specific firmware parameters
  wcn36xx: Add ability to download wcn3680 specific firmware parameters
  wcn36xx: Latch VHT specific BSS parameters to firmware
