[PATCH v2 5/5] ARM: dts: imx6dl-yapp43: Add support for new HW revision of the IOTA board

From: Michal Vokáč
Date: Tue Mar 14 2023 - 14:06:58 EST

The PCB used for all the current boards (Ursa, Draco, Hydra, Orion, Crux)
was slightly redesigned and delivers some new features while some unused
components were removed.

- External RTC chip with supercap added.
- Secure element added.
- LCD display power supply enable/disable signal added.
- Touch keyboard reset and interrupt signals added.
- Factory reset GPIO button added.
- Audio codec LM49350 (EoL) removed and replaced by PWM audio output.
- QCA8334 switch was replaced by Marvell 88E6141.
- PCIe completely removed.
- uSD card removed and replaced by board-to-board expansion connector.

There are four configuration variants of the new board:

1. Pegasus
The board configuration is based on Orion with the following major changes:

- Quad core SoC
- 4GB of RAM
- RTC with supercap added
- Secure element added

2. Pegasus+
This is the very same board as Pegasus but uses the i.MX6QuadPlus SoC.

3. Lynx
The board configuration is based on Draco with the following major changes:

- DualLite SoC
- 1GB of RAM
- RTC with supercap added
- Secure element added

4. Phoenix
The board configuration is based on Ursa with the following major changes:

- DualLite Soc
- 1GB of RAM
- RTC with supercap added
- Secure element added
- LCD display support removed
- UART2 removed
- Factory reset GPIO button added

Changes in v2:
- properly sorted entry for imx6q-yapp4-pegasus.dtb in Makefile
- dropped deprecated fec binding for phy-reset-duration and
phy-reset-gpios. Reset moved to mdio switch subnode.
- moved status property to the end in led-controlled device node
- removed status = "okay" where not needed
