Subject: [PATCH v4 0/2] add support for Phytec PCM-049 and PCM-959

As should be clear for the title and patch title, this is adding initial
support for the OMAP 4460 SOM and dev kit for Phytec's PCM959 evaluation
kit.

The PCM049 is a legacy SOM offered by Phytec:
https://www.phytec.com/legacy-soms/
There was a vendor BSP offered by Phytec, but that never entered the
Device Tree era. This patch is meant to change that.

My development bootloader has moved to U-Boot, but I have verified
Barebox works in the past. When booting from SD card, either bootloader
should work. When booting from Barebox, the NAND OOB layout is
incompatible between the bootloader and the kernel.

I haven't had any OOB / ECC errors in the NAND at all, which was my
main concern. Due to that, I'm submitting this as a patch instead of
an RFC. Hardware ECC correction seems to be fully functional.



v3->v4
* Add initial .yaml documentation instead of omap.txt
Thanks to Andrew Davis <[email protected]> for posting their WIP patch
set, which was the basis for patch 1, with Rob's feedback.
* Removed Rob's "Acked-by" because the patch is completely different
* Removed unnecessary "omap-4430" from compatible in .dts

v2->v3
* Acked-by on patch 1
* Code review changes (see patch 2 for details)
* Fix intermittent NAND failures (patch 2)

v1->v2
* Almost everything moved into the SOM (PCM-049) .dtsi. Only the
LED chip is dev-board specific.
* Fix pinmux associations (*pmx_core was applying *pmx_wkup
entries... I'm surprised that didn't cause more issues)
* Documentation added

* Updates from review:
* Board compatible strings added
* Hyphen / underscore changes
* Remove unnecessary status="okay" entries
* Generic names used (regulator, led-1, etc.)

Subject: [PATCH v4 2/2] arm: dts: omap4: pcm959: add initial support for phytec pcm959

The Phytec PCM-959 is a development platform for the Phytec PCM-049 SOM.
Add initial functionality for the board. The verified interfaces and
peripherals are listed below for the SOM (PCM-049) and the dev board
(PCM-959)

The omap2plus_defconfig was used for testing. Only the On-board LEDs
required CONFIG_LEDS_PCA9532 addition.

PCM-049:
i2c1
* EEPROM at 0x50
* TMP102 (hwmon) at 0x4b
twl6030
GPMC
* Ethernet
* Flash
Serial (ttyS2 console)

PCM959:
MMC1
On-board LEDs (with CONFIG_LEDS_PCA9532)

v3->v4
* Remove unnecessary "omap-4430" compatible string

v2->v3
Code review changes:
* Remove unnecessary "okay" statuses
* Utilize gpio funciton / color instead of label
* Clean up pinctrl whitespace
* Change label of TWL6030 to "pmic"
* Clean up general whitespace
Behavioral changes:
* Utilize "gpmc-wait" instead of "rb-gpios". The initial
configuration would suffer about a 1/100K NAND access
failure, snowballing into corrupted NAND after enough
boot cycles / downloads. This one was fun to figure out!
* Adjustments to gpmc-nand timings from testing.

v1->v2
* Almost everything moved to the SOM (PCM049)
* Fix where omap_pmx_wkup were actually getting applied to
omap_pmx_core.
* Use hyphens instead of underscores for names
* Remove unnecessary entries of "status=okay"
* Use generic "regulator" and "led" names
* add compatible strings for the dev board and SOM

Oops. Caught this typo too late. I can wait until after the merge window
or resend next week. There's probably other feedback.

How will this work if I add the same file? Why not take my WIP patch, make
the suggested changes from Rob, then have it as your first patch in this
series?

Is your WIP intended to convert all omap.txt to ti,omap.yaml? Or chunk
off devices one at a time?

If the former, when your patch is done it should be a pretty simple
rebase conflict resolution. If the latter (which feels more digestable)
this offers that template. This was Rob's / Tony's suggestion, albeit
before you sent your patch set.


Anyway, I'm happy to do any of the following:

1. Take Andrew's patches, add these references and re-submit.
2. Keep this set as-is (with the typo fix) and when Andrew's WIP is done
it should be an easy rebase before submission.
3. Wait for Andrew's WIP to be done, then submit with this update.


I'd like to avoid #3 because I don't know where this might fall on your
priorities list.

Low priority for me, I'd suggest #1 or they probably will not be
converted anytime soon.

If you are willing to do #1, that's certainly my preference.

That would be great!
