[PATCH 00/13] ARM: shmobile: dts: Update console parameters

[Geert Uytterhoeven]

	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, bockw, kzm9d, kzm9g), "console="
    parameters are removed from the kernel command lines, as they're no
    longer needed for DT-only platforms,
  - On some boards (genmai, kzm9g), the console alias is changed to
    "serial0", for consistency with other boards (the first serial port
    is always called "serial0", unless labeled otherwise); this does
    mean the device changes its name to /dev/ttySC0 in userspace, which
    also happened on R-Car Gen2 before,
  - On kzm9d, a console alias is added.
	    
Tested on r8a73a4/ape6evm, r8a7740/armadillo, r8a7778/bockw,
r8a7779/marzen, r8a7791/koelsch, and sh73a0/kzm9g.

Thanks for applying!

In case it helps anyone now or in the future the output with earlyprintk

As noted elsewhere the serial2 -> serial0 portion of
this patch seems to result in no console.

In case it helps anyone now or in the future the output with earlyprintk

[PATCH 09/13] ARM: shmobile: kzm9g dts: Update console parameters

[Geert Uytterhoeven]

Change the console alias to "serial0", for consistency with other
boards (the first unlabeled serial port is always called "serial0").
Drop the "console=" parameters from the kernel command line, as they're
no longer needed for DT-based platforms.
Add the serial port config to chosen/stdout-path.

[PATCH 09/13] ARM: shmobile: kzm9g dts: Update console parameters

[Geert Uytterhoeven]

Change the console alias to "serial0", for consistency with other
boards (the first unlabeled serial port is always called "serial0").
Drop the "console=" parameters from the kernel command line, as they're
no longer needed for DT-based platforms.
Add the serial port config to chosen/stdout-path.

I would prefer not to take the serial1 -> serial0 portion of this change at
this time as it causes a user-space visible change: the console moves from
ttySC1 to ttySC0. I noticed this because I no longer made it all the way
to user-space which was expecting a console on ttySC1.

As per my remarks regarding the armadillo800eva I would prefer not
to make the serial2 -> serial0 portion of this change.

As a bonus the  serial2 -> serial0 portion of this change seems to prevent
console output during boot too. I've posted some debuging using earlyprintk
in reply to this patch in case its useful.

I am wary of the new serial1 alias.
Have you checked to see if there is any user-space visible change
as a result of this?

As per my remarks regarding the armadillo800eva I would prefer not
to make the serial4 -> serial0 portion of this change.

Changing &scif2 to serial0 creates a user-space visible change:
the console moves from ttySC2 to ttySC0.

I'm unsure how we can update to use the new syntax without encountering
this problem.

I'm unable to test porter and silk but they look ok to me.

As per my remarks regarding the armadillo800eva I would prefer not
to make the serial4 -> serial0 portion of this change.

Changing &scif2 to serial0 creates a user-space visible change:
the console moves from ttySC2 to ttySC0.

I'm unsure how we can update to use the new syntax without encountering
this problem.

I'm unable to test porter and silk but they look ok to me.

I would prefer not to take the serial1 -> serial0 portion of this change at
this time as it causes a user-space visible change: the console moves from
ttySC1 to ttySC0. I noticed this because I no longer made it all the way
to user-space which was expecting a console on ttySC1.

-- start before --
[    0.050000] e6c50000.serial: ttySC1 at MMIO 0xe6c50000 (irq = 25, base_baud = 0) is a scifa
[    0.780000] console [ttySC1] enabled
-- end before --

[    0.050000] e6c50000.serial: ttySC0 at MMIO 0xe6c50000 (irq = 25, base_baud = 0) is a scifa

>   ARM: shmobile: genmai dts: Update console parameters

As per my remarks regarding the armadillo800eva I would prefer not
to make the serial2 -> serial0 portion of this change.

As a bonus the  serial2 -> serial0 portion of this change seems to prevent
console output during boot too. I've posted some debuging using earlyprintk
in reply to this patch in case its useful.

I am wary of the new serial1 alias.
Have you checked to see if there is any user-space visible change
as a result of this?

We made a similar change on koelsch, lager, and marzen (cfr. below) before,
so I assumed this is OK?

Does it? Serial0 was already pointing to scif2 since Magnus' commit
8025e3ff4ca972a0 ("ARM: shmobile: marzen: Board specific serial port order").
