Hi i tried to use the uart_C of the the odroid-c2.
I enabled it in the dts file. During boot it crashed when the
the sdcard slot is addressed.
After long search in the net i found this:
https://forum.odroid.com/viewtopic.php?f=139&t=25371&p=194370&hilit=uart_C#p177856
After changing the pin definitions accordingly erverything works.
Uart_c is functioning and sdcard ist working.
Fixes: 6db0f3a8a04e46 ("pinctrl: amlogic: gxbb: add more UART pins")

Martin asked Otto to resend with a proper formatting, but seem he forgot to

this looks fine to me based on the description on the Odroid forums so:

...as well as going the extra mile (writing a patch and submitting it)
your patch is looking good to me apart from some small formal issues:
- some typos in the commit message (int -> in, addressd -> addressed,
definitios -> definitions, ist -> is)
- please add the following line above your Signed-off-by line (to get
your fix also into -stable kernels): Fixes: 6db0f3a8a04e46 ("pinctrl:
amlogic: gxbb: add more UART pins")
- your "Signed-off-by" has to be in a specific format
- patches must be sent inline (not as attachment)
- the pinctrl maintainers are not Cc'ed (so they won't notice this patch)
here's a simplified version of the patch submission flow that I use:
- (change the code)
- git commit --signoff (give a good description why you are changing
things, include a Fixes line if appropriate)
- git format-patch HEAD~1
- run ./scripts/checkpatch.pl 0001-*.patch (fix all checkpatch errors,
"git commit --amend" the changes, then run git format-patch again)
- find the email recipients with: ./scripts/get_maintainer.pl 0001-*.patch
- run: git send-email 0001-*.patch --to=<maintainer or mailing list
email> --to=<another maintainer mailing list or email> --cc=<more
mailing lists...>
feel free to ask if you have any questions
I'm looking forward to an updated patch!
Martin
