2020-05-13rtw88: fill zeros to words 0x06 and 0x07 of security cam entryPing-Ke Shih
8723D adds some experimental features to word 0x06 of cam entry, so fill zeros to initialize them to off state. For existing chips, these two words are reserved and always zeros, so this change is harmless for them.

2020-05-13rtw88: 8723d: Add coex supportPing-Ke Shih
8723D is a Wifi+BT combo card. To make them work properly, we need coex mechanism to avoid interference, such as TX simultaneously. Basically, coex.c provide main algorithm to deal with many use cases, and this commit adds some parameters and ops differ from other chips, because coex hardware and WiFi generation are changed.

2020-05-13rtw88: 8723d: Add power trackingPing-Ke Shih
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
2020-05-13rtw88: 8723d: add IQ calibrationPing-Ke Shih
IQ calibration is used to calibrate RF characteristic to yield expected performance. Basically, we do calibration twice and compare the similarity to determine calibration is good or not, if not we do the third calibration, and then compare with the results of first and second calibration. If it still not similar, IQK is failed. Before doing calibration, we need to backup registers that will be modified in calibration procedure, and restore these registers after calibration is done. A calibration procedure can divided into four sub-procedures that are S1-TX, S1-RX, S0-TX and S0-RX. Where, S1 and S0 represent to path A and B respectively. Each sub-procedure configure proper registers, and then rigger one-shot calibration and poll until completion. For RX calibration, it needs to do twice one-shot calibration, first one is to yield parameter used by second one. The result of TX part is stored for TX power tracking that adjusts TX AGC to output expected power.

A boundary is used to split pages into two parts, head part is used to store TX packets coming from host, and tail part is reserved for special purposes, such as beacon packet, null data packet and so on. The TX packets coming from host have many categories, such as VO, VI, BE, BK, MG and etc. When going into head part of TX FIFO, they are classified to four priority queue named low, normal, high and extra priority queues. Each priority queue occupies predefined number of page, if a certain priority queue is full, TX packet will store into PUB priority queue. Similarly, RX FIFO is 16k and split into two parts, head part is used to store RX packets, and tail part is 128 bytes and used to store report. Thus, we fill this boundary to register as well.

2020-04-23rtw88: 8723d: Add mac power-on/-off functionPing-Ke Shih
The mac power-on flow consists of three steps: 1. pre_sys_cfg (Before switching power state) 2. power_switch (Switching power state) 3. init_sys_cfg (Settings after swtiching power state) When switching power state, driver will load and parse the power sequence tables. For 8723D devices, the logics for parsing are most same except for the polling function. 8723D devices need to toggle BIT_PFM_WOWL twice. The settings after power state is switched for 8723D devices are quite different with other devices, extract a legacy function for them. For power-off flow, 8723D devices have the same logic with existing chips. But warning printed if we run power-off sequence in power-off state: rtw_pci 0000:03:00.0: failed to poll offset=0x5f8 mask=0xff value=0x0 The scenario is user do 'ifconfig up' that will run power-on sequence to bring up and then run power-off sequence to enter idle (IEEE80211_CONF_IDLE). Then, user do 'ifconfig down' that will run power-off sequence again, and the warning is shown. Original code check power-on state to avoid to run power-on sequence twice, and this commit extends to check both power-on and power-off states.

2020-04-23rtw88: no need to send additional information to legacy firmwarePing-Ke Shih
The firmware of 11AC devices need more information to support more offload functions, such as IQK.

2020-04-23rtw88: add legacy firmware download for 8723D devicesPing-Ke Shih
The WLAN CPU of 8723D device is different from others, add legacy firmware download function for it. A new variable wlan_cpu is used to decide which firmware download function we should use. Legacy firmware file contains 32 bytes header including version and subversion. When downloading to wlan cpu, header is excluded. Firmware is downloaded via beacon queue to reserved page that is a part of TX buffer. Since 11N WLAN CPU uses different control registers, this patch introduces related control registers.

2020-04-21rtw88: set power trim according to efuse PG valuesTzu-En Huang
8822C devices have power trim, thermal and PA bias values programmed in efuse. Driver should configure the RF components according to the values. If the power trim is not configured, then the devices might have distortion on the output tx power.

2020-04-21rtw88: 8723d: Add RF read/write opsPing-Ke Shih
8723D use SIPI to indirectly read RF register instead of directly read, so introduce a new struct rtw_rf_sipi_addr and new function rtw_phy_read_rf_sipi(). Since other chips don't use the new function, only 8723D needs to fill struct rtw_rf_sipi_addr in rtw_chip_info. Because there are two kinds of functions for reading RF registers now, change rtw_phy_read_rf() to chip->ops->read_rf() in rtw_phy_write_rf_reg_sipi() so that we can switch tp proper RF read functions depends on the type of the chip. Though 8723D is an 1x1 chip, it has two RF PHY and we can switch to one of them, and that should be configured properly. Hence, add a fix_rf_phy_num to struct rtw_chip_info to allow driver to set one of the PHY's registers for 8723D, even it is only 1x1. Another variable rf_phy_num is introduced to keep the constraint number of RF path we can access, and its value is: rf_phy_num = (fix_rf_phy_num ? fix_rf_phy_num : rf_path_num) Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Zong-Zhe Yang <kevin_yang@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/20200420055054.14592-5-yhchuang@realtek.com

8723D doesn't support beamform because rtw88 only supports VHT beamform but 8723d doesn't have VHT capability. Though 8723d doesn't support beamform, BSS_CHANGED_MU_GROUPS is still marked as changed when doing disassociation. So, add wrapper functions for all beamform ops to make sure they aren't NULL before calling.
