2025-03-31wifi: rtw89: 8852bx: support different SAR configs by antennaZong-Zhe Yang
Calculate difference of SAR configs between RF path A and RF path B. And then, based on the calculated result, set the TX power reference CR (control register). Finally, declare to support SAR by antenna in 8852b/8852bt chip info.

2025-03-13wifi: rtw89: add support for negative values of dBm to linear conversionKuan-Chung Chen
Enhanced the dBm to linear conversion function to accommodate negative dBm values and improved the precision from 1 dBm to 0.25 dBm.

2024-12-05wifi: rtw89: 8922a: use RSSI from PHY report in RX descriptorChih-Kang Chang
The PPDU status of probe response will fail to parse the IE due to being filtered by the to_self check. Therefore, we parse RSSI from PHY report in RX descriptor.

2024-11-18wifi: rtw89: handle different TX power between RF pathKuan-Chung Chen
The dynamic antenna gain (DAG) may independently apply different TX powers for each RF path. This can be accomplished by using the larger TX power as the reference path and adjusting the TX power of the other path based on the difference. Currently only 8852BE/8852BTE/ 8852CE are supported.

2024-11-06wifi: rtw89: 8852b: change RF mode to normal mode when set channelChih-Kang Chang
Set the RF mode from 0xA(low power mode) to 0x3(Normal mode) to avoid abnormal TX waveform in OFDM rate. Originally the RF mode will be changed to normal mode by the firmware after entering LPS once. Therefore, this change does not affect power saving.

2024-08-27wifi: rtw89: 8852bx: use right chanctx whenever possible in RFK flowZong-Zhe Yang
No longer access chan with hard-code RTW89_CHANCTX_X whenever possible. Instead, obtain the right chanctx from somewhere and use it in RTL8852BX RFK (RF calibration) related code.

2024-08-02wifi: rtw89: rename sub_entity to chanctxZong-Zhe Yang
Originally, we planed to fill MAC_0/1 indicators with chanctx and use sub_entity_xxx for these things. However, there are some reasons listed below which make us give up this plan after we know our Wi-Fi 7 HW design. 1. one link is bound to one HW band during its life time but, one link might change chanctx dynamically 2. in concurrent mode, assume 1st vif is MLD 1st vif's 2nd link might use the same chanctx as 2nd vif but, they are not on the same HW band So, we let sub_entity_xxx stuffs deal with only chanctx now. And, to be more readable, we rename sub_entity related words to chanctx. No logic is changed.

For 8852BT, the initial settings of BT-coexistence is a little bit different, so add the extra handles. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://patch.msgid.link/20240701014619.7300-2-pkshih@realtek.com

The BT coexistence part of 8852B and 8852BT are similar, so move shared code into common module. Don't change logic for existing RTL8852BE. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://patch.msgid.link/20240701014619.7300-1-pkshih@realtek.com

The channel configuration of 8852BT is very similar but a little different to 8852B, so use chip ID as condition to add extra handles including external loss compensation, ADC configurations, spur settings and so on. Don't affect existing 8852BE. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://msgid.link/20240607070659.80263-3-pkshih@realtek.com

New upcoming chip is RTL8852BE-VT (or RTL8852BTE; 8852BT PCIE interface), which is a variant of 8852B, and many codes excepting to RF calibration can be shared, so move common code to an new kernel module named rtw89_8852b_common.ko.
