[PATCH v2] ARM: DTS: OMAP4: Add OMAP4 Blaze Tablet support

[PATCH v2] ARM: DTS: OMAP4: Add OMAP4 Blaze Tablet support

[Ruslan Bilovol]

The OMAP4 Blaze Tablet is TI OMAP4 processor-based
development platform in a tablet formfactor.
The platform contains many of the features found in
present-day handsets (such as audio, video, wireless
functions and user interfaces) and in addition
contains features for software development and test.

This patch adds initial support for the OMAP4 Blaze
Tablet development platform. Additional functionality
depends on different drivers and code modifications that
are not upstreamed yet or do not support DT yet, so will
be added later.

v2:
 - Rebased onto 'for_3.11/dts' branch of bcousson/linux-omap-dt tree
 - Bound more hardware and picked up updates from omap4-sdp

Might be good to see the TWL interrupt pin information made available as 
well?

Allow me to rephrase a comment a little bit more :)
Similar to twl4030_omap3.dtsi, we could introduce twl6030_omap4.dtsi. 
this could contain the common pins used for 6030.

Allow me to rephrase a comment a little bit more :)
Similar to twl4030_omap3.dtsi, we could introduce twl6030_omap4.dtsi. 
this could contain the common pins used for 6030.
  &omap4_pmx_wkup {
          pinctrl-names = "default";
          pinctrl-0 = <

Why do we want to send this upstream?
What is the advantage to having this supported?

I don't believe we need to add another community board.  We have a SDP 
and Panda.

Why not? Just the .dts file is needed nowadays and it
may make it easier to support various other omap4 based
tablets that have similar features.

Agree, I'm planning to do this later as part of moving common things into
some System-On-Module(SOM)-specific files, as discussed previously
here https://patchwork.kernel.org/patch/2118371/

Because:
a) it is still widely used for prototyping devices
b) you can still buy it from svtronics
c) it has different set of devices on board so we have ability to
   work with things like:
  - widescreen high-resolution LCD panel
  - different touchscreen controllers
  - gpio keys (on 'Blaze Tablet')
  - another set of sensors
  - HS USB Host related stuff etc
d) some features may be easily accessible only on BlazeTalet board
    (comparing to Panda/SDP), like USB HSIC connection
e) it is shipped with OMAP4470, support of which we are going to send upstream
f) with Device Tree it's easy to support this board :)

;) - link was wrong!
http://svtronics.com/omap?product_id=15 is more like it -> Blaze
tablet by default comes in 4460/4470 variants. I suggest introducing
4470 variant here.
I am aware of the SOM compatibility and ability to support 4430 SOM on
tablet as well, but to keep tablet alive and reduce scope of testing,
keeping just 4470 in place might be a good choice.

just my 2 cents, no strong feelings towards either. :)

I dont think I was mentioning about that - I just would really like to
avoid duplication of 6030 information all over the place. if we can
avoid it, lets start consolidating.

Yes, this makes sense. I think as soon as OMAP4470 reach upstream, we can easily
switch the BlazeTablet's  .dts to 4470

I think there are (at least) two revisions of the blaze tablet, the
newer one has a higher resolution LCD. I don't know what the other
differences are.

I think you have the newer revision. I have the older. Do you know about
the diff of those revisions, or more importantly, will the same blaze
tablet support work for the older revision also?

Yes, it was manufacturing some first revision of BlazeTablet but now
it is out of production.
On Svtronics there is ability to buy only BlazeTablet2 and we use only
it last year as
development platform.

The difference is known - another display, sensors, diffs in routing
gpio to leds etc..
The same DTS will allow to boot BlazeTablet and BlazeTablet2 but
number of supported features
of course will be less in case of first revision of BlazeTablet

Since first revision of Blazetablet is not available to buy and we do
not use it for some time
I think there is no needs in doing support of it upstream.

Ruslan
