1f242a3de7 rt2x00: reverse external PA capability flag logic
Consequently refer to external PA instead of inverting the logic and
use an internal PA capability flag which is a bit confusing.
Currently this is used for Rt3352 only, but MT7620A also allows for an
external PA which will be supported by a follow up patch.

4da5e7ea13 rtlwifi: btcoex: 21a 1ant: avoid LPS/IPS mismatch for pnp notify
When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

signal, and they can transmit simultaneously, hence there is no need to
switch antenna between wifi and bt.

684df42cd5 rtlwifi: btcoex: 23b 2ant: check more cases when bt is queuing
If bt is queing, we need to set the packet priority properly.
Originally we only consider if wifi was connected or not, but now we
also consider if bt is under abnormal scan or wifi is scanning, roaming
or linking, and set the coex table.

609d59acb6 rtlwifi: btcoex: 23b 2ant: add pnp notidy to avoid LPS/IPS mismatch
When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

b01127b268 rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma duration
For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.

6e84ab604b brcmfmac: properly align buffers on certain platforms with 64 bit DMA
Systems with 64 bit DMA at least partially require buffers to be used
for DMA to be 8-byte-aligned. One example is Amlogic Meson GX.
Switching the MMC/SDIO driver for this platform to SG DMA mode
resulted in problems due to unaligned buffers.

Fortunately the brcmfmac driver has a global define for the alignment.
Changing it to 8 fixed the issues with Meson GX.
