From: Wen Gong <quic_wgong at quicinc.com>
Buglink: https://bugs.launchpad.net/bugs/2098104
Impact: This is a patchset the we (TUXEDO Computers) currently apply on top of the Ubuntu 6.8 kernel to make it run smoothly on all our devices. All patches apply smoothly to 6.8.
Fix: These are all patches already upstream, just not on the 6.8 branch, because they where upstreamed after that one was already EOL.
Testcase: We run this patchset for all our customers devices (we basically maintain our own OEM branch) so it is quite field testet. Besides that, whenever a new patch was added we did regression testing on a selection of devices.
Currently ath12k only downloads the same regdb.bin file for all WCN7850
chips, actually ath12k needs to distinguish all different WCN7850 chips.
This is to re-use the string type which includes bus, chip id, board id,
vendor, device, subsystem-vendor, subsystem-device and variant for
WCN7850 to distinguish different regdb in board-2.bin.
ath12k will first load board-2.bin and search in it for the regdb data
with the above parameters. If matched with one regdb data, download it
to firmware. And if not, download regdb.bin instead.
Add enum value ATH12K_BD_IE_REGDB and enum type ath12k_bd_ie_regdb_type
to distinguish regdb data and board data since they are in the same file
board-2.bin.
