From: Max Chou <[email protected]>
In the commit of linux-firmware project, rtl8852cu_fw.bin is updated as
FW v2 format[1]. Consider the case that if driver did not be updated for
FW v2 supported[2], it can not use FW v2.
By Canonical's suggestion, older driver should be able to load FW v1,
so rtl8852cu_fw.bin will be revert to the previous commit as FW v1 and
add rtl8852cu_fw_v2.bin as FW v2. This item will be started on
linux-firmware project.
In this commit, the driver prefers to load FW v2 if available. Fallback to
FW v1 otherwise.
Note that the driver has supported to extract the data for v1 and v2
since the commit[1].
The previous FW format of RTL8852C is v1. After the commit[2], the FW format
was changed to v2. Only RTL8852C suffered the different FW formats, so
we will use rtl8852cu_fw.bin for the original commit as FW v1 and
rtl8852cu_fw_v2.bin for the future maintained as FW v2. Other Realtek chips
will not been impacted by this patch.
To do on linux-firmware project after this commit.
1. revert '55e7448533e7 ("rtl_bt: Update RTL8852C BT USB firmware
to 0x040D_7225")'
=> rtl_bt/rtl8852cu_fw.bin: FW v1 (stay at ver. 0xD7B8_FABF)
2. Add a new commit for rtl8852cu_fw_v2.bin
=>rtl_bt/rtl8852cu_fw_v2.bin: FW v2 (to be maintained)
