[PATCH] ARM: OMAP3: Fix omapfb's problem on OMAP3430sdp

[stanley.miao]

In RGB565 mode, red and blue color are filtered, so the picture on LCD
looks green and dark.

Fix omapfb's problem on OMAP3430sdp.

Tested by me. I get a nice penguin. But no blue background that I
usually see on TI kernels. I have no expertise on this, so this is
just an observation.

The below code will execute in 2430SDP also because is_sil_rev_less_than()
will be false there.
You need some mechanism to avoid that right?

	nothing to do with your patch, but these should be converted to
gpiolib.

missing space again. Please, run scripts/checkpatch.pl --strict patch.diff
before sending your patches so we avoid obvious style mistakes.

Thanks. I resolved the style problem. If gpio function needs to be
changed, I think it should be in a single patch.

How about putting the is_sel_rev_greater_than test within the

Good, this will run fewer instructions on 2430sdp.

But checkpatch.pl rejected that, yes?  Fixed in a later
version I see.

... and in "static int sdp2430_panel_enable(...)" this would
seem to be wrong.  But for that matter, lcd_2430sdp.c should
not be relevant for any 3430 board anyway...

If that file is, oddly, being shared between two boards ...
then put that code in the "if (machine_is_omap_3430sdp())"
block.  And someone should consider renaming the file if
it's not specific to the 2430 SDP.

It has been fixed in a later version.

this was shared between two boards.

OMAP3430_ES1 doesn't have this problem.

Not the point.  Why have 2430 chips run code that only makes
sense on 3430 silicion?

Have you noticed my later version ? I have modified it to
if (is_sil_rev_greater_than(OMAP3430_REV_ES1_0)).

For clarity, I re-send this request.


In RGB565 mode, red and blue color are filtered, so the picture on LCD
looks green and dark.

Fix omapfb's problem on OMAP3430sdp.
