rtw88: 8723d: Add power tracking When chip's temperature is changed, RF characters are changed. To keep the characters to be consistent, 8723d uses thermal meter to assist in calibrating LCK, IQK, crystal and TX power. A base thermal value is programmed in efuse, all calibration data in MP process is based on this thermal value. So we calucate the delta of thermal value between the base value, and use this delta to reference XTAL and TX power offset tables to know how much we need to adjust. For IQK and LCK, driver checks if delta of thermal value is over 8, then they are triggered. For crystal adjustment, when delta of thermal value is changed, we check XTAL tables to get offset of XTAL value. If thermal value is larger than base value, positive table (_p as suffix) is used. Otherwise, we use negative table (_n as suffix). Then, we add offset to XTAL default value programmed in efuse, and write sum value to register. To compensate TX power, there are two hierarchical tables. First level use delta of thermal value to access eight tables to yield delta of TX power index. Then, plus base TX power index to get index of BB swing table (second level tables) where register value is induced. BB swing table can't deal with all cases, if index of BB swing table is over the size of the table. In this case, TX AGC is used to compensate the remnant part. Assume 'upper' is the upper bound of BB swing table, and 'target' is the desired index. Then, we can illustrate them as compensation method BB swing TX AGC ------------------- -------- -------------- target > upper upper target - upper target < 0 0 target otherwise target 0 For debug purpose, add a column 'rem' to tx_pwr_tbl entry, and it looks like path rate pwr base (byr lmt ) rem A CCK_1M 32(0x20) 34 -2 ( 0 -2) 0 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200512102621.5148-4-yhchuang@realtek.com
