These contain code specific to RTL8821AU. Signed-off-by: Bitterblue Smith <rtl8821cerfe2@gmail.com> --- v2: - Patch is new in v2. - All of this used to be in patch 18/20 in v1. - Use "k < 3" instead of "k <= 2" in the IQK code. - Replace some while loops with for loops in the IQK code. - Use rtw_write8 instead of rtw_write8_mask in rtw8821a_coex_cfg_ant_switch. The mask was 0xff. - Constify structs/arrays. v3: - No change. v4: - No change. --- drivers/net/wireless/realtek/rtw88/rtw8821a.c | 1197 +++++++++++++++++ drivers/net/wireless/realtek/rtw88/rtw8821a.h | 10 + 2 files changed, 1207 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8821a.c create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8821a.h
