I works on vanilla linux/kernel to enable bluetooth over uart.
Since I don't have the schematics, wanted to know a little bit
more about the interconnect.
Today, broadcom 43438 controller rx/tx are connected to pin <32 33>.
Basically ,ttyAMA0/uart0 is configured to manage this controller (from DT).
- Would like to enable DMA for this UART, is it supported ?
- Would like to enable hw flow control, any cts/rts rooted to the bcm chip ?
- Any other gpio/irqs (power, suspend, wakeup) ?
