2023-05-25wifi: rtw89: add chip_ops::query_rxdesc() and rxd_len as helpers to support ↵Ping-Ke Shih
newer chips The next generation chips use different RX descriptor format, so add a chip_ops to hook suitable handlers. Also, the length of RX descriptor is different, so add a variable to store the length according to chip and descriptor content dynamically. Then, the code can be more general.

For realtek regulatory, there are following two kinds of configurations to determine whether to allow UNII-4 band, i.e. 5.9GHz channels. 1. default setting according to whether chip support it or not 2. evaluate realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_59G_EN (func. 6) If (1) is false, we won't try (2) and just disallow UNII-4. Otherwise, if (2) is not supported or returns a non-specific value, we follow the default setting either. Besides, this commit aims to add decision logic in rtw89 regulatory. Actually, driver doesn't register UNII-4 yet. That will be handled by another commit.

2023-04-14wifi: rtw89: support parameter tables by RFE typeZong-Zhe Yang
One chip can have different RFE (RF front end) types which we will judge at runtime. And, different RFE types may use different RF parameter tables. Though we didn't really meet this case previously, we are going to meet it on upcoming chip RTL8851B. So, this commit handles parameter tables for runtime RFE type. We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms. Then, each chip defines its default parameter tables, and if needed, it can configure extra parameter tables by RFE type. Finally we determine runtime parameter tables by RFE type if one is configured. Otherwise, we use the default parameter tables. For now, we just move all settings under default parameter tables. We will configure parameter tables by RFE types in separate commits afterwards.

2023-04-14wifi: rtw89: add firmware format version to backward compatible with older ↵Ping-Ke Shih
drivers In the discuss threads [1] [2], new firmware format break user space because older drivers can't recognize new firmware format. To avoid this, the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver try to load it. Old drivers only load original and understandable firmware rtw89/rtw8852b_fw.bin. More, new driver will be still backward compatible with old firmware, so original firmware can be used by new driver. If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin will be given. The same rules will be applied like above. So, we will have firmware like below in linux-firmware in the future. rtw89/rtw8852b_fw-2.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852b_fw.bin After this patch, MODULE_FIRMWARE() of 8852A/B/C become rtw89/rtw8852a_fw.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852c_fw.bin [1] https://lore.kernel.org/linux-wireless/df1ce994-3368-a57e-7078-8bdcccf4a1fd@gmail.com/T/#m24cb43be31a762d0ea70bf07f27ae96c59f6931b [2] https://bugzilla.kernel.org/show_bug.cgi?id=217207 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230320130606.20777-4-pkshih@realtek.com

2022-10-12wifi: rtw89: 8852b: add power on/off functionsPing-Ke Shih
We need power on function to enable hardware circuits of MAC/BB/RF, and then download firmware and load PHY parameters. After more settings, it starts to work. When it enters idle, use power off function to have the lowest power consumption.

2022-10-12wifi: rtw89: 8852b: add chip_ops::set_channel_helpPing-Ke Shih
This chip_ops is to assist set_channel, because we need setup and restore hardware before and after set_channel. Before set_channel, we stop transmitting, reset PPDU status, disable TSSI, and disable ADC. After set_channel, do opposite things in reverse order.

2022-10-11wifi: rtw89: 8852b: add chip_ops::set_channelPing-Ke Shih
set_channel is main function to configure channel and bandwidth for all layers, namely MAC, BB and RF. Additionally, MAC layer enables CCK rate checking to avoid wrong rate from driver. BB layer configures SCO (Sample Clock Offset) for CCK, TX gain error/offset, and reset baseband hardware circuit after all configurations done.

2022-10-11wifi: rtw89: 8852b: add HFC quota arraysPing-Ke Shih
HFC is short for HCI flow control. These arrays are used to set quota according to operating modes, which are SCC or download firmware.

2022-10-04wifi: rtw89: 8852b: add chip_ops to read phy capPing-Ke Shih
This efuse region is to store PHY calibration, and it is a separated region from the region that stores MAC address. Then, use these data to configure via chip_ops::power_trim that is a calibration mechanism of TX power.
