The reset GPIO of WCD9390/WCD9395 is active low and that's how it is routed on typical boards, so correct the example DTS to use expected polarity, instead of IRQ flag (which is a logical mistake on its own).

Qualcomm WCD9390/WCD9395 Codec is a standalone Hi-Fi audio codec IC.
|
|
It has RX and TX Soundwire devices.
|
|
The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem
|
|
accessible over an I2C interface.
|
|
The Audio Headphone and Microphone data path between the Codec and the USB-C Mux
|
|
subsystems are external to the IC, thus requiring DT port-endpoint graph description
|
|
to handle USB-C altmode & orientation switching for Audio Accessory Mode.
