No, I think we're going for overkill here by not doing
serial_pl01x.c as
platform data. ns16550 does platform data for this already. This
sounds like the lowest overhead way to get the clock
populated and not
have some DT data that's not going to be accepted upstream.
ummmm I am a bit lost at this point, could we recap please?
Lets update the recap:
- Please re-submit the dts file, now with whatever form is
in v4.12-rc1,
saying as such in the commit (if it's just the commit message that
changes, that's fine and great).
The DTS file in v4.12-rc2 still does NOT contain the usb node.
==> Should I then not use the DM on USB so I can avoid DTS changes?
Well, you can either put it in the -u-boot.dtsi file for the board, and
remove that later once it's upstream.
yes I'll do that. thanks.
- Please update serial_pl01x.c to be able to get the clock
via platform
data, update and test your board to confirm it works.
um, It gets tricky;
I can not use platform_data since I can not use SERIAL_DM because
the device tree does have a UART node which gets picked up.
How about disabling the node in -u-boot.dtsi for the board and then you
can use platform data,
I dont think that would because CONFIG_OF is enabled for USB; so the
kernel dtsi that contains the uart node (without the clock!) will be
picked by u-boot and the uart will not be initialized properly.
I still think that the simplest solution is to let me merge with the
kernel's device tree plus this u-boot.dtsi [1];
then just get rid of the file when possible (and NEIHER the source
code NOR the configs) would need to change
[1]
https://github.com/ldts/poplar-u-boot/blob/upstream/arch/arm/dts/hi3798cv200-u-boot.dtsi
Yes, sorry. [1] needs to be updated to disable uart0 so that you can
use platform data, at least for now. I do want to talk more with Rob
about the general problem this exposes.
so you want me to
1) keep the node in
https://github.com/ldts/poplar-u-boot/blob/upstream/arch/arm/dts/hi3798cv200-u-boot.dtsi
2) add status=disable
3) then add the platform_data
BUT for the pl011 driver to take the platform_data dont I also have to
disable CONFIG_OF?
but if I disable CONFIG_OF then I lose USB_DM
am I wrong?
