[PATCH 0/2] Support for TeeJet Mt.Ventoux

From: Ilya Yanok <hidden>
Date: 2011-12-26 23:08:30

Split into two parts:
 1. Device tree only to be used with board-generic (only serial works)
 2. Full board support via custom machine file for board-testing

Ilya Yanok (2):
  mt_ventoux: very basic support for TeeJet Mt.Ventoux board
  mt_ventoux: support for TeeJet Mt.Ventoux board

[PATCH 1/2] mt_ventoux: very basic support for TeeJet Mt.Ventoux board

From: Ilya Yanok <hidden>
Date: 2011-12-26 23:08:31

Very basic support for TeeJet Mt.Ventoux board. Able to boot via
board-generic and ramdisk/initramfs, however most of peripherals are
not supported. Produces tons of twl4030 related errors as this board
doesn't have twl4030 installed.

Although the TRM states that there is a vdds_dsi signal,

Either way, it can't be switched off, I think...

I will forward this info to hardware guys and ask about wiring. For now
I will leave it as is. Thanks for this information it turned to be some
kind of mystery. It would be great if you could give some pointer to the
datasheet regarding VDDSHV and DSS.

[PATCH V2] mt_ventoux: support for TeeJet Mt.Ventoux board

From: Ilya Yanok <hidden>
Date: 2011-12-27 23:09:37

This patch adds support for TeeJet Mt.Ventoux board based on TAM3517
SOM. Supported devices:
 - Serial
 - Ethernet
 - NAND
 - USB host
 - LCD
 - Touchscreen
 - CAN controller
 - ADC128S converter

Signed-off-by: Ilya Yanok <redacted>
---

Changes from V1:

 - Fixed indentation (use tabs not spaces)
 - Fixed over 80 characters lines
 - Added #if defined(CONFIG_SENSORS_ADCXX_MODULE) to allow adcxx to be a
   module.
 - Fixes for compilation with CONFIG_TOUCHSCREEN_ADS7846!=y
  - Added defined(CONFIG_TOUCHSCREEN_ADS7846_MODULE)
  - Moved call to omap_ads7846_init to separate small function
  - Register fixed regulator used for touchscreen only if the driver is
    enabled
 - Changed board name (MT_VENTOUX -> Mt.Ventoux)

Although the TRM states that there is a vdds_dsi signal,
it looks, from the datasheet, that VDDSHV is used to power the DSS.
Either way, it can't be switched off, I think...
Therefore, depending on your board wiring, you can leave it as fixed
regulator or bind to a supply on TPS65023.
I will forward this info to hardware guys and ask about wiring. For now
I will leave it as is. Thanks for this information it turned to be some
kind of mystery. It would be great if you could give some pointer to the
datasheet regarding VDDSHV and DSS.
Well, there is no direct pointer to that information, but
I've found these facts:
1) the "Ball Characteristics" tables state that the DSS related pins
   (and also many others) are powered by the VDDSHV.
2) the estimated power consumption of VDDSHV is the largest after the
   VDD_CORE, which is typical for DSS, but it is also one of the largest
   power domains, so I guess this cannot be a valid argument ;-)
3) On the "Voltage domains" diagram, only the VDD_CORE is exposed and
   DSS is not listed in it, but there are other domains which are not
   exposed... (this only can exclude the DSS from VDD_CORE, but not
   absolutely, as datasheets can have mistakes or just not give that piece
   of information).

Still, it is a guess and not verified information.

Perhaps the AM35xx should have a separate .dtsi file?
In that case there is a possibility you will get multiple
<SoC>.dtsi files with the same copy/pasted "disable" stuff.
Of course this is better than having multiple board files doing this.

What do you think on splitting the whole thing into <IP>.dtsi files,
Like I have explained here [2]?

Hi Tony,

comments, do you think they can be merged in your tree ?
Yes I can carry some board-*.c files until device tree is
usable for basic features. There's still some hsmmc changes
pending that I'd like to get out of the way before adding
new ones as then it means I have to keep updating those
board files separately.

Tony
