[PATCH v4 0/3] Add support and enable the debug UART in the Pixel 3a and Pixel 3a XL

[Pablo Correa Gómez via B4 Relay]

In order to get logs through the SBU pins in Google Pixel devices, it is
necessary to add support to the devicetree, and enable the corresponding
UART. With this code and an USB-Cereal board, I was able to get full kernel
logs through serial.
