Re: Review of concept of changing UART flow control from Kconfig to DTS config
Hi (and +Krzysztof in Cc),

Hi,To be clear, this PR is limited to nRF SoCs only, it is not a
I find this to be a bit of a step backwards for applicationI'm having a bit of trouble understanding what you mean here.
The boolean hw-flow-control property is still available for enabling
hardware flow control for both UART and UARTE:
Looking at the code, if hw-flow-control is disabled in DTS (the
default), then in both drivers cfg->flow_ctrl is false. The HAL
configuration structure ends up with flow control disabled in that case:
So flow control at a SoC level seems to be turned off by default.
It's true that many boards in PR #25999 do enable it by default, e.g.
But it seems like at a board maintainer level, you can leave the SoC
default as-is to make flow control "opt in" as requested.
It looks like flow control is off by default and it's opt-in; what did I
