Michael LoandFelix Fietkau 63f18baa5b wifi: mt76: mt7925: fix invalid array index in ssid assignment during hw scan
Update the destination index to use 'n_ssids', which is incremented only
when a valid SSID is present. Previously, both mt76_connac_mcu_hw_scan()
and mt7925_mcu_hw_scan() used the loop index 'i' for the destination
array, potentially leaving gaps if any source SSIDs had zero length.

Michael LoandFelix Fietkau 0ca6ed4e27 wifi: mt76: mt7925: add test mode support
The test mode interface allows controlled execution of chip-level
operations such as continuous transmission, reception tests, and
register access, which are essential during bring-up, diagnostics,
and factory testing.

Michael LoandFelix Fietkau 7bf6a2914a wifi: mt76: mt7925: ensure all MCU commands wait for response
Modify MCU command sending functions to wait for a response,
ensuring consistent behavior across all commands and improves
reliability by confirming that each command is processed
successfully.

setting for the scan command and let it be controlled by
the firmware as mt7921.

Michael LoandFelix Fietkau 5fdb1841f7 wifi: mt76: mt7925: fix a potential association failure upon resuming
In multi-channel scenarios, the granted channel must be aborted before
suspending. Otherwise, the firmware will be put into a wrong state,
resulting in an association failure after resuming.

With this patch, the granted channel will be aborted before suspending
if necessary.

Michael LoandFelix Fietkau eb0d0ce344 wifi: mt76: mt7921: fix suspend issue on MediaTek COB platform
MediaTek's controller driver on COB platform (e.g. MT8188) is
capable of controlling power supplies and reset pin of a component
(e.g. a WIFI chip) in power-on and power-off process.

Due to this optional feature, mt76 need to inform controller
that mt76 need to keep power during suspend. Otherwise WIFI will be
powered off when system enters suspend process.

The "wakeup-source" property was used for the device that need
this to go into suspend mode so that mt76 suspend handler doesn't
fail and the system is able to enter into a suspend state.

An example:
wifi: mt7921@0 {
	wifi0{
		reg = <0x0000 0 0 0 0>;
		wakeup-source;
	};
};
