[PATCH rtw-next 1/6] wifi: rtw89: Use the correct power sequences for USB/SDIO

[Bitterblue Smith]

Make rtw89_mac_pwr_seq() select the right parts of the power sequences
based on the interface type.

This is only relevant for RTL8852A. The other chips don't use power
sequences.

[PATCH rtw-next 2/6] wifi: rtw89: Add rtw8852a_dle_mem_usb

[Bitterblue Smith]

Add rtw8852a_dle_mem_usb and its various quotas and sizes in struct
rtw89_mac_size_set.

"dle" could be "Data Link Engine" or "Double Link Engine". These are
some parameters needed for RTL8852AU.

[PATCH rtw-next 3/6] wifi: rtw89: Add rtw8852a_hfc_param_ini_usb

[Bitterblue Smith]

"hfc" means "hci fc" which is "Host Control Interface Flow Control".
These are some parameters needed for RTL8852AU.
