Hi Simon, Magnus,
This patch series updates the console parameters in the DTSes for
various Renesas ARM boards.
- For all of them, the serial port config is added to
chosen/stdout-path, as per current best practices,
- On some boards (armadillo, genmai, kzm9g), the console alias is
changed to "serial0", for consistency with other boards, and to
match current best practices (the first serial port should be called
"serial0", unless labeled otherwise).
This does mean the device changes its name to /dev/ttySC0 in
userspace. I believe it's OK to make this change, as we did the
same for koelsch, lager, and marzen before.
- On some boards (armadillo, kzm9d, kzm9g), "console=" parameters are
removed from the kernel command lines, as they're no longer needed
for DT-only platforms.
Beware leftover parameters in bootargs environment variables!
- On kzm9d, a console alias is added.
Changes compared to v1:
- Drop patches that have been applied,
- Change one-line summary prefixes to match current arm-soc practices,
- Drop name changes of pfc subnodes,
- Reword patch descriptions.
Dependencies:
- Due to dropping the name changes of pfc subnodes, this has an
esthetic (never realized before this does exist ;-) dependency on
"[PATCH 00/19] ARM: dts: renesas: Name pfc subnodes after device
names".
Tested on all five affected boards (some with remote access), to verify
there is no other impact to userspace than the change of the console
device to /dev/ttySC0, which may be handled automatically, depending on
your userspace.
Thanks for applying!
