Ryder LeeandFelix Fietkau e48235308b wifi: mt76: mt7915: accumulate mu-mimo ofdma muru stats
The stats are clear-on-read, which makes it very difficult for tools
to adequately deal with wrapped stats and with keeping good totals.

So, accumulate these values when they are read from the firmware/radio
and present totals to user-space.

In the expression "map[i].qid << 24" starts as u8, but is promoted to
"signed int", then sign-extended to type "unsigned long", which is not

Ryder LeeandFelix Fietkau 2c172bb6cd wifi: mt76: mt7915: fix band_idx usage
The commit 006b9d4ad5bf introduced phy->band_idx to accommodate the
band definition change for mt7986 so that the band_idx of main_phy
can be 0 or 1. Accordingly, the source of band_idx 1 has switched to
"phy != &dev->phy" or "dev->phy.band_idx = 1".

We still use ext_phy to represent band 1 somewhere in driver, so fix it.
Also, band_idx sounds more reasonable than dbdc_idx, so change it.

Shayne ChenandFelix Fietkau 6f871f35e3 mt76: mt7915: use mt7915_mcu_get_txpower_sku() to get per-rate txpower
Get per-rate txpower with mcu command. This is the preparation of
co-driver for the next chipset, which has different tmac power registers
but can share this same command.

Ryder LeeandFelix Fietkau 3c90f35ddd mt76: mt7915: add thermal sensor device support
This provides userspace with a unified interface, hwmon sysfs, to monitor
temperature in the hardware and can be adapted to system monitoring tools.

For reading temperature, cat /sys/class/ieee80211/phy*/hwmon*/temp1_input
