Neil, if you want you could also drop this from your series and let me
handle this (just let me know). I would even go one step further and
export the CLKID_UART0, CLKID_UART1 and CLKID_UART2 gates and pass
them as "pclk" for uart_{A,B,C}
I'll even *try* to test if this works on real hardware (my Meson8m2
board has a RTL8723BS SDIO wifi + bluetooth chip - wifi driver support
has been pretty bad so far - but I'll try to see if I can get and
messages out of the bluetooth part)
just let me know if you want me to handle this patch for you
