Subject: [PATCH v2 00/24] ARM: dts: imx7-colibri: device tree improvements
From: Marcel Ziswiler <marcel.ziswiler@...adex.com>
This is a general update of the Colibri iMX7 device tree files.
The Toradex Colibri family is composed of a SoM that can be plugged on
various carrier boards, with carrier boards allowing multiple optional
accessories (e.g. display, camera, ...).
The device tree sources are structured into a SoM dtsi and a carrier dts
which then includes the SoM dtsi. The SoM dtsi defines and enables the
functionality self-contained on the SoM and prepares for the
functionality provided by the carrier HW or accessories so that the
carrier dts then can enable or amend nodes provided. Accessories are
enabled in overlays depending on HW configuration.
Please find the following colibri-imx7 device trees improvements:
- Display/Touch Functionality Overhaul
Rename display interface to match other modules to make it easier to
use device tree overlays.
The parallel RGB interface (lcdif) and all related stuff turn on in a
device tree overlay. Keep them disabled in the main devicetree.
As these subsystems are provided by module and not a part of boards,
move their definitions into the module-level devicetree.
Disable ad7879 touchscreen which turns on in a devic tree overlay.
Remains it disabled in the main devicetree.
The Toradex 7" Capacitive and 10" LVDS touch screens are Atmel MXT
peripherals available on the I2C bus for touchscreen events. Add
atmel_mxt_ts node to the module-level device tree. Also, provide pinmux
configuration for the INT/RST inputs from SODIMM pins 106/107 for most
carrier boards or an external touchscreen adapter inputs configured to
SODIMM pins 28/30.
- Ethernet Improvements
Add the MDIO bus with the respective PHY.
Add Ethernet aliases which is required to properly pass MAC address
from bootloader.
Add delay for on-module phy supply.
- USB Device/Host Switching
Add usb dual-role switching using extcon.
- MMC/SD
The original Colibri specification only defined 3.3 volt TTL signaling
and relied on external on-carrier pull-ups for the SD_DATA[0..3] lines.
The latest carrier boards like Iris V2 on the other hand are now UHS-I
compliant by leaving such external on-carrier pull-ups away relying on
module- or even SoC-level ones which pull up to resp. signaling voltage.
In such cases, the carrier board-level device tree may explicitly delete
the no-1-8-v property to enable full UHS-I support.
Also, fix SD/MMC regulator for the carrier boards using UHS-I modes.
- Add Iris and Iris V2 Carrier Board Device Trees
Add support for Toradex Iris carrier boards.
Changes in v2:
- Add Krzysztof's acked-by. Thanks!
- Revert change on arch/arm/boot/dts/imx6dl-colibri-iris.dts which
slipped into this patch set by error.
- Re-based on top of Shawn's for-next.
