2020-12-08rtw88: Fix fall-through warnings for ClangGustavo A. R. Silva1-1/+1
In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by replacing a /* fall through */ comment with the new pseudo-keyword macro fallthrough; instead of letting the code fall through to the next case. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R.

2020-12-08rtw88: reduce polling time of IQ calibrationChin-Yen Lee1-9/+8
When 8822CE is associating with AP, driver will poll status bit of IQ calibration to confirm the IQ calibration is done, and then move on the association process. Current polling time for IQ calibration is 6 seconds. But occasionally driver fails in polling the status bit because the status bit is not set after IQ calibration is done. When it happends, association process will be serieously delayed up to 6 seconds. To avoid it, we reduce polling time to 300ms, in which the IQ calibration can be done.

'const struct dev_pm_ops rtw_pm_ops' is declared by pci.c, and it should be declare as 'extern' in pci.h. Without 'extern' causes every file including pci.h has an individual instance of rtw_pm_ops but not reference to the one declared in pci.c If kernel config, like test robot, doesn't build driver as module, it leads multiple definition.

2020-12-07rtw88: declare hw supports ch 144Zong-Zhe Yang1-0/+1
When driver was developed, FCC regulation didn't enable channel 144 and there was no demand for channel 144 at that time. Although HW actually supports channel 144, driver didn't announce channel 144. Therefore, channel 144 (20 MHz), channel 142 (40 MHz) and channel 138 (80 MHz) couldn't be used. Today, channel 144 has been enabled by regulations and is gradually being supported. With test requirements, we declare hw supports channel 144.

Some AP will not follow the power save request, or it cannot stop transmission until its queue is empty. It may bring the decreasing of data rate. WLAN firmware will count is the AP still leaked packet after power save handshake was done or not to enable WLAN slot extend mechanism. The extend WLAN slot mechanism will extend the WLAN slot after power save handshake, 5 ms per times, maximum is 5 times to received the leaked packet to avoid the rate lower down. And if the transmission was already locked at CCK rate. The extended WLAN slot can also increase the opportunity that we can received the CCK's long packet and be released from CCK rate. While BT multi-link status was finished, there is possible that it still has some packet remained for seconds. Add a timer to remain the multi-link mechanism to protect WLAN Rx.

The original mechanism may cause A2DP glitch during WiFi connecting AP. Because the original TDMA may decrease too much A2DP slot. This patch add a timer and variable to let the case A2DP + WL_Connecting performed more well.

2020-11-10rtw88: coex: modified for BT info notifyChing-Te Ku2-22/+31
Add counter to count BT info C2H command for debug usage. It could present the C2H channel situation. Fix BT IQK state decision condition for counting. The original condition is wrong, it would cause coexistence mechanism going to the wrong strategy. New format supports getting TDMA parameter from WL firmware, since coexistence needs current TDMA parameter to decide strategy. Remove unnecessary operations about scoreboard, it is not a must for current version.

2020-11-07rtw88: add C2H response for checking firmware leave lpsChin-Yen Lee6-5/+54
Originally driver checks if firmware has left lps via reading the setting of REG_TCR register. But this way may fail when firmware is frequently changing power state. Therefore, firmware provides a safer option for driver. When firmware leaves lps successfully, it sends a C2H response to inform driver.

2020-11-07rtw88: sync the power state between driver and firmwareChin-Yen Lee1-39/+30
In current flow, driver issues power requests to firmware for entering or leaving deep power mode. But driver does not wait for an ack from firmware via reading CPWM register when driver requests to enter deep power mode. The behavior will lead to unsynchronized state between firmware and driver. Furthermore, consecutive same power requests may confuse firmware and leads to unexpected value of CPWM register. This patch ensures that the power request will wait for an ack from firmware and only send one power request each time.

BT firmware will report BLE-HID and BLE-RCU in different profile. We can distinguish the two profile from BT info now. Add the coexistence for BLE-HID coexistence, it can make BLE HID work more smoothly. BLE-HID need to Tx/Rx packet more frequently to respond user operation, but RCU doesn't. In the case of RCU coexistence, it will make Wi-Fi have a higher priority to earn more Wi-Fi throughput. If BLE-HID go for the same case, it will make user feel mouse is lagging.
