Add a node for the PMU module of the WCN6855 present on the sa8775p-ride
board. Assign its LDO power outputs to the existing WiFi/Bluetooth module.
Signed-off-by: Miaoqing Pan <quic_miaoqing@quicinc.com>
---
v2:
- fix wcn6855-pmu compatible to "qcom,wcn6855-pmu".
- relocate pcieport0 node in alphabetical order.
v3:
- add 'qcom,ath11k-calibration-variant = "SA8775P"'.
v4:
- update 'ath11k-calibration-variant' to "Ride".

What exactly is Ride? Is there just one Ride board? I thought it's a board family name. Also, could you please extend the commit message with messages from the ath11k driver, showing the chip_id / board_id ? -- With best wishes Dmitry

The board-id is non 0xff, do you still think we need to add 'qcom,ath11k-calibration-variant', following is the WLAN chip board data info, bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2,qmi-board-id=519.bin

The extra variant will increase the size of board-2.bin. In board-2.bin one board file can have multiple names, that was designed exactly for cases like this. So the memory inrease is just the size of string (plus few bytes for the TLV headers). Dmitry is correct here. It's much better to have unique names instead trying reuse the same names for different hardware. For example, if later we actually need different board files then that's simple to do just in board-2.bin. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
