This is a driver for pureLiFi X, XL, XC devices which use light to transmit data, so they are not compatible with normal Wi-Fi devices. The driver uses separate NL80211_BAND_LC band to distinguish from Wi-Fi. The driver is based on 802.11 softMAC Architecture and uses native 802.11 for configuration and management. Station and Ad-Hoc modes are supported. The driver is compiled and tested in ARM, x86 architectures and compiled in powerpc architecture. This driver implementation has been based on the zd1211rw driver. Signed-off-by:

Three chip_ops are implemented in this patch. The ::set_txpwr_ctrl and ::init_txpwr_unit are called when we up interface and then configure TX power registers to initial values. The ::set_txpwr_ctrl is to configure 'txpwr_ref' to make basic output TX power of OFDM and CCK rate to be the same. The ::init_txpwr_unit is to initialize TSSI (a method to do TX power compensation depends on thermal value) control and bandedge. The ::set_txpwr is called once switching channel. First, it sets TX power for each rate section (e.g. CCK, OFDM), and then sets TX power offset between 1SS and 2SS rate. Finally, it sets TX power limit to prevent power over regulation.

When disconnecting, it warns somethings after power is off, and we can't do HCI IO. So, add this patch to avoid below messages: rtw89_8852ce 0000:03:00.0: timed out to flush pci txch: 11 rtw89_8852ce 0000:03:00.0: failed to pre-release fwcmd Signed-off-by:

RPP is to report certain skb(s) can be freed, and TX BD indicates which TX descriptors can be freed. Normally, TX BD is happened before RPP. In low power mode, RPP can happen ahead, so change flow to handle this case. Signed-off-by:

In low power mode, we need to pause PCI to configure IMR and PCI ring index registers accordingly, because the regular registers are power-off in this mode. In the transition moment named paused in code, we can't touch ring index, so don't kick off DMA immediately. Instead, queue them into pending queue, and kick off after the moment. There are three low power modes, which are RF off/clock gate/power gate, but PCI enter low power mode in later two modes only. So, add a mask to achieve this. Signed-off-by:

Normally, we re-enable interrupt by napi_poll, but for this special situation, we must turn it on immediately because napi_poll isn't scheduled. Signed-off-by:

In lower power mode, there are very low amount of RX, and it must process in a separated function instead of schedule_napi(), because the existing napi_poll does many things to optimize performance, but not all registers can access in low power mode. The simple way is to use threadfn to process the simple thing. Signed-off-by:

To reclaim TX BD, we need to read hardware reading index to determine if any DMA is complete. Since this IO spends time, do this thing only if we really need it when TX BD has no free buffer corresponding to target skb. The experimental result shows that reading counter decreases from 26,000 to 130 per second. Signed-off-by:

RPWM/CPWM are registers that can set and check low power mode. Since chips use different address, add a field to access them in common flow. Signed-off-by:

8852CE uses different but similar IMR/ISR registers, and its masks are also different in various states, so add config_intr_mask ops to configure masks according to under_recovery or low_power states. Signed-off-by:

BB does many settings during setting channel. First is to configure CCK for 2G channels, and then basic channel and bandwidth settings with a encoded channel index that will report to driver when we receive packets. Configure spur elimination to avoid spur of CSI and NBI tones in certain frequencies. Also, it initializes BT grant to arrange path sharing with BT according to band. Finally, reset TSSI and BB hardware to ensure it stays in initial state. Signed-off-by:
