This adds the device tree include file for the Toradex Colibri T20
Computer on Module (COM). It's only valid for the 512MB RAM version of
the module, as the 256MB version needs different EMC tables and flash
configuration. To make this clear the suffix -512 was added to the board
compatible string.
The Colibri T20 uses a Tegra2 SoC and has onboard USB Ethernet and AC97
sound.
Still some things like onboard NAND support missing, but should be a
good base for further development.

Still some things like onboard NAND support missing, but should be a

This adds the device tree for the Toradex Iris carrier board used
together with a Colibri T20 512MB COM.
The Iris has the following features, in brackets the current status:
- DVI and VGA output through DVI-I connector (DVI-D enabled and tested)
- LVDS output
- 1 USB host port (enabled and tested)
- 1 USB OTG port (enabled)
- 100 MBit Ethernet (enabled and tested)
- 5 UART ports (2 on 10way headers enabled and tested)
- 1 MicroSD Slot (enabled and tested)
- Audio connectors (enabled, only HP out and Line-in tested)
- i2c RTC
- GPIO connector (enabled, only sparsely tested)
- external i2c bus
- 4 PWM out
- analog in

This adds the device tree for the Toradex Iris carrier board used
together with a Colibri T20 512MB COM.
The Iris has the following features, in brackets the current status:
- DVI and VGA output through DVI-I connector (DVI-D enabled and tested)
- LVDS output
- 1 USB host port (enabled and tested)
- 1 USB OTG port (enabled)
- 100 MBit Ethernet (enabled and tested)
- 5 UART ports (2 on 10way headers enabled and tested)
- 1 MicroSD Slot (enabled and tested)
- Audio connectors (enabled, only HP out and Line-in tested)
- i2c RTC
- GPIO connector (enabled, only sparsely tested)
- external i2c bus
- 4 PWM out
- analog in

You should probably add that compatible value to

I assume that all of those nodes are meant to have status="okay"?
Oh, I see those are in the top-level board .dts file. You may as well
put all the properties there; stuff like the GPIOs and regulators at
least would be purely specific to the individual board, and not the COM.
I guess we should really move the serial node's clock-frequency property
in the SoC .dtsi files.

I think just call that "regulators"; the final board .dts file can
easily add more sub-nodes to this node, so there's no need to try and
avoid any naming conflict here. See Cardhu as an example.
> + vdd_5v0_reg: com_reg0 {
Those should be named regulator@0, regulator@1, etc.

That reg = <3>;

I would like to keep everything that is defined by the COM to reside in
the COM dtsi. You are right that the regulator in this case is board
specific and should be moved to the board file, I missed this while
splitting things out. But at least the GPIO is defined by the fixed COM
pinout.

I don't really see the benefit of merging those nodes. They are separate
regulators, some are located on the COM, others on the carrier board. So
I would like to keep them in separate nodes, unless you have strong
feelings to change this.

I would like to keep everything that is defined by the COM to reside in
the COM dtsi. You are right that the regulator in this case is board
specific and should be moved to the board file, I missed this while
splitting things out. But at least the GPIO is defined by the fixed COM
pinout.

I don't really see the benefit of merging those nodes. They are separate
regulators, some are located on the COM, others on the carrier board. So
I would like to keep them in separate nodes, unless you have strong
feelings to change this.

If these are really defined by the COM itself, it does indeed make sense
for the COM .dtsi file to define those properties. But, I have a hard
time understanding how the COM design can force the carrier module into
using a particular GPIO for the SD controller CD functionality; couldn't
the carrier use any GPIO passed through the COM<->carrier connector for
any purpose?

The issue here is that if we don't do this, we end up with wierd node
names; plain "regulators" is a fairly canonical name for what the name
contains, and purely indicates the type of the node. "com_regulators" is
unusual, and starts to encode identity into the node name itself, which
is something not usually done in the node name (differentiation between
identities is usually done using the unit address; "@nnn"),

It's not a GPIO anymore as soon as it hits the COM<->carrier connector.
The connector pin assignment is strictly specified. There are a lot of
freely assignable GPIOs on the connector, everything related to a
specific function is not part of this.
The Colibri specification dictates which pin to use if you want to
realize a SDcard CD. This is done so that modules and carrier boards are
interchangeable. In fact you can just as well run a new Colibri T30
module on a years old carrier designed for the ColibriPXA series of
modules.

Hm, ok. Keeping some space in between module and carrier regulator
addresses should do as well.

No Tegra Platform is running PLL_P at another rate than 216MHz, nor is
any using an other PLL as UART source clock. Move attribute into SoC
level dtsi file to slim down board DT files.

* [PATCH v2 1/3] ARM: DT: tegra: move serial clock-frequency attr into the SoC dtsi
@ 2013-01-22 21:46 ` Lucas Stach
0 siblings, 0 replies; 22+ messages in thread
From: Lucas Stach @ 2013-01-22 21:46 UTC (permalink / raw)
To: linux-arm-kernel
No Tegra Platform is running PLL_P at another rate than 216MHz, nor is
any using an other PLL as UART source clock. Move attribute into SoC
level dtsi file to slim down board DT files.

* [PATCH v2 2/3] ARM: DT: tegra: Add Colibri T20 512MB COM

This adds the device tree include file for the Toradex Colibri T20
Computer on Module (COM). It's only valid for the 512MB RAM version of
the module, as the 256MB version needs different EMC tables and flash
configuration. To make this clear the suffix -512 was added to the board
compatible string.
The Colibri T20 uses a Tegra2 SoC and has onboard USB Ethernet and AC97
sound.
Still some things like onboard NAND support missing, but should be a
good base for further development.

v2:
- remove some whitespace
- remove nodes that don't carry any additional info
- unify regulator node between module and carrier board

* [PATCH v2 2/3] ARM: DT: tegra: Add Colibri T20 512MB COM
@ 2013-01-22 21:46 ` Lucas Stach

From: Lucas Stach @ 2013-01-22 21:46 UTC (permalink / raw)
To: linux-arm-kernel
This adds the device tree include file for the Toradex Colibri T20
Computer on Module (COM). It's only valid for the 512MB RAM version of
the module, as the 256MB version needs different EMC tables and flash
configuration. To make this clear the suffix -512 was added to the board
compatible string.
The Colibri T20 uses a Tegra2 SoC and has onboard USB Ethernet and AC97
sound.
Still some things like onboard NAND support missing, but should be a
good base for further development.

v2:
- remove some whitespace
- remove nodes that don't carry any additional info
- unify regulator node between module and carrier board

This adds the device tree for the Toradex Iris carrier board used
together with a Colibri T20 512MB COM.
The Iris has the following features, in brackets the current status:
- DVI and VGA output through DVI-I connector (DVI-D enabled and tested)
- LVDS output
- 1 USB host port (enabled and tested)
- 1 USB OTG port (enabled)
- 100 MBit Ethernet (enabled and tested)
- 5 UART ports (2 on 10way headers enabled and tested)
- 1 MicroSD Slot (enabled and tested)
- Audio connectors (enabled, only HP out and Line-in tested)
- i2c RTC
- GPIO connector (enabled, only sparsely tested)
- external i2c bus
- 4 PWM out
- analog in

v2:
- unify regulator node between module and carrier
- use correct regulator for sdhci

I've applied the series to Tegra's for-3.9/dt branch.
