i.MX23 patches

[Sascha Hauer]

Hi all,

The following is the result of working on the Chumby. Not all patches
are strictly for the chumby, most notable is the renaming of mach-stm
to mach-mxs.

Sascha

The following changes since commit 1a0ddc54ef631a7f7d7ed1831bda09eb10bafbfd:

  imx: add reg definitions for imx25 and imx35 boot source. (2011-01-20 09:42:34 +0100)

are available in the git repository at:
  nowhere ..BRANCH.NOT.VERIFIED..

[PATCH 08/10] fb i.MX23/28: rename imx_fb_videomode to imx_fb_platformdata

[Sascha Hauer]

It's not a video mode, it contains video modes, so rename
the struct to what it actually is.

[PATCH 09/10] ARM: rename STM arch to mxs

[Sascha Hauer]

We never supported the sigmatel stm chips and probably
never will. So do the first step and rename the architecture
to mxs just like in the kernel.

I was just about to send you the same kind of patch, as this bug bit me during
kernel boot when using cpufreq.

As you are working on imx23 and video driver, what do you think of my previous
patches ? I sent them in January the 4th:

ARM STM/i.MX: Add possibility to choose the bit per pixel for STM
    video driver
ARM STM/i.MX: Add possibility to select the data mode for stm video
      driver ( DCn signal is high )
ARM STM/i.MX: Add the reset control of LCD

They should need to be rebased on this new patch set as you made some changes
with the name of the structures and the name of the files. But before doing
this I would like to know if there was a chance that they will be applied in
barebox.

This looks ok.

>       driver ( DCn signal is high )

Looks ok. What is this pin good for? Is this bit used in conjunction
with other bits which happen to have the right value for you?

> ARM STM/i.MX: Add the reset control of LCD

We use the same pin as gpio and toggle it in the platform specific hook,
so I could rebase my chumby patch on this one.

For the last two patches I prefer having flags in the platform data
rather than having a u32 for a single flag.

You made me dig in the datasheet and check my code. And finally this
patch is pointless! The DCn signal which seems related to LCD_RS is
only used in MPU interface whereas we use Dotclock interface.
I just checked again and without it, my LCD still worked. It seems
that I forgot to test this patch alone, as my configuration need
the following patch to work, I didn't notice this patch did nothing.
Sorry for this fake patch :(

How could we process?

Will you get the 1st patch as is ?

For the other, have you a git tree available where all your patches lie?

I merged my mx23 patches and your first patch to -next. You can rebase
your remaining patches on -next and I'll convert the chumby to use the
reset pin later.
