v2 cover Add Bananapi R4 Pro support

From: Frank Wunderlich <[email protected]>

BananaPi R4 Pro is a MT7988A based board which exists in 2 different hardware versions:

- 4E: 4 GB RAM and using internal 2.5G Phy for WAN-Combo
- 8X: 8 GB RAM and 2x Aeonsemi AS21010P 10G phys

common parts:

- MediaTek MT7988A Quad-core Arm Corex-A73,1.8GHz processor
- 8GB eMMC flash
- 256MB SPI-NAND Flash
- Micro SD card slot
- 1x 10G SFP+ WAN
- 1x 10G SFP+ LAN
- 4x 2.5G RJ45 LAN (MxL86252C)
- 1x 1G RJ45 LAN (MT7988 internal switch)
- 2x miniPCIe slots with PCIe3.0 2lane interface for Wi-Fi NIC
- 2x M.2 M-KEY slots with PCIe3.0 1lane interface for NVME SSD
- 3x M.2 B-KEY slots with USB3.2 for 5G Module (PCIe shared with key-m)
- 1x USB3.2 slot
- 1x USB2.0 slot
- 1x USB TypeC Debug Console
- 2x13 PIN Header for expanding application

official product information:
https://docs.banana-pi.org/en/BPI-R4_Pro/BananaPi_BPI-R4_Pro

The PCIe is per default in key-m state and can be changed to key-b with the pcie-overlays.

changes:
v2:
- dropped "dt-bindings: arm: mediatek: add BPI-R4 Pro board" which was applied from v1
- added new patch "disable 2.5G phy and enable at board layer"
- squashed "mt7988a: Add label for ssusb0" to r4pro dts commit
- some updates after angelos review to the r4pro dts commit
- fixed buck4 and ldo displayed voltage (cannot be controlled by software) to match schematic
- reorder fan after eth node (alphanumeric)
- reorder spi-tx after spi-rx (alphanumeric)
- follow reg first, then others also for spi-nand partitions
- drop 2pg5 phy disabling node (due to new patch disabling by default)
- change order of pinctrl (first number than names)
- fix commit prefix (mediatek was missing)

Typos happen. Also for me.

A good idea is when you change mail address try to negotiate something simpler, this is one of the reasons a lot of maintainers have simple mail addresses such as [email protected] (which will be my next mail address the day it is needed).

Thank you

Code/description is not changed,but angelos tag is wrong there (missing a in email,above is also wrong). Not sure if it has effects for get_maintainers.pl (non-maintainers part). But would be better if you can still fix it.

In reply to Frank Wunderlich

From: Frank Wunderlich <[email protected]>

The internal 2.5G phy of mt7988 is only used by some specific board variants.
Disable it by default and enable it where needed.

From: Frank Wunderlich <[email protected]>
BananaPi R4 Pro is a MT7988A based board which exists in 2 different hardware versions:
- 4E: 4 GB RAM and using internal 2.5G Phy for WAN-Combo
- 8X: 8 GB RAM and 2x Aeonsemi AS21010P 10G phys
[...]

Applied to v6.18-next/dts64, thanks!
