Patch 1/3 and 2/3 are to refine code related to firmware. Among them, patch 2/3 is to use schedule_work() to load firmware, so it will be simpler to load more firmware and files in the future. The upcoming files include predefined format string of firmware log, another MCU firmware of WiFi 7 chip, and so on. I will explain them when we submit the patch. Patch 3/3 is to be backward compatible with old driver. Currently, only 8852b support firmware-1.bin, and other can support more, like firmware-2.bin and firmware-3.bin. Supported matrix is listed below: dirver-0 driver-1 driver-2 firmware.bin O o o firmware-1.bin x O o firmware-2.bin x x O Big-O: MODULE_FIRMWARE() small-o: supported firmware x: driver doesn't try to load This patchset is based on two other patchsets: - "[PATCH v2] wifi: rtw89: add counters of register-based H2C/C2H" - "[PATCH v4 0/5] wifi: rtw89: preparation of multiple interface concurrency support" Ping-Ke Shih (2): wifi: rtw89: use schedule_work to request firmware wifi: rtw89: add firmware format version to backward compatible with older drivers Zong-Zhe Yang (1): wifi: rtw89: fw: use generic flow to set/check features drivers/net/wireless/realtek/rtw89/core.c | 27 ++-- drivers/net/wireless/realtek/rtw89/core.h | 12 +- drivers/net/wireless/realtek/rtw89/fw.c | 138 +++++++++--------- drivers/net/wireless/realtek/rtw89/fw.h | 14 +- drivers/net/wireless/realtek/rtw89/rtw8852a.c | 10 +- drivers/net/wireless/realtek/rtw89/rtw8852b.c | 10 +- drivers/net/wireless/realtek/rtw89/rtw8852c.c | 10 +- 7 files changed, 132 insertions(+), 89 deletions(-)
