The ADMAC attached to the AOP has complex power sequencing, and is power gated when the probe callback runs. Move the register reads to other functions, where we can guarantee that the hardware is switched on. Signed-off-by: Sasha Finkelstein <[email protected]>
To be used by RTKit consumers to check if an endpoint is present and should be enabled. Signed-off-by: Sasha Finkelstein <[email protected]>
This system endpoint is advertised by AOP and also needs to be turned on for it to function. Signed-off-by: Sasha Finkelstein <[email protected]>

Similar in function to the one from std, but takes GFP flags. Signed-off-by: Sasha Finkelstein <[email protected]>
Just a wrapper over dev->parent. Signed-off-by: Sasha Finkelstein <[email protected]>

This is the base device for a multi-function co-processor present on certain Apple SoCs. On M-series Macs it is in charge of internal microphones, and various environmental sensors. Signed-off-by: Sasha Finkelstein <[email protected]>

Apple SoCs have their microphones connected to the AOP co-processor, in order to among other things implement the "voicetrigger" functionality. Add a driver for the "High power audio input" AOP endpoint. Signed-off-by: Sasha Finkelstein <[email protected]>
The AOP co-processor present on certain Apple SoCs exposes various environmental sensors as "HID" (really not) devices. Add drivers for the ambient light and lid angle sensors exposed that way. Signed-off-by: Sasha Finkelstein <[email protected]>

This is a co-processor in charge of various security-related features on Apple SoCs. This driver only boots the firmware, which is needed to unlock the mic secure disable on certain laptop models. Signed-off-by: Sasha Finkelstein <[email protected]>

This adds the AOP driver, microphone support, lid angle sensor driver, and ambient light sensor driver (disabled pending some m1n1 work). Also contains just enough of a SEP driver to unlock SECDIS on base m1.
Obsoletes #151
Draft, since the mic output is basically useless without correct userspace configs (coming soontm).
