This patch adds support for STUSB1600 USB Type-C port controller, used on
I2C4 on stm32mp15xx-dkx.
The default configuration on this board, on Type-C connector, is:
- Dual Power Role (DRP), so set power-role to "dual";
- Vbus limited to 500mA, so set typec-power-opmode to "default" (it means
500mA in USB 2.0).
typec-power-opmode is used to reconfigure the STUSB1600 advertising of
current capability when its NVM is not in line with the board layout.
On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN. So power
operation mode depends on the power supply used. To avoid any power
issues, it is better to limit Vbus to 500mA on this board.
ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and
signal is active low.
USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx
boards, so disconnection are not detected.
Without DWC2 usb-role-switch:
- if you unplug the USB cable from the Type-C port, you have to manually
disconnect the USB gadget:
echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
- Then you can plug the USB cable again in the Type-C port, and manually
reconnect the USB gadget:
echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
With DWC2 usb-role-switch, USB gadget is dynamically disconnected or connected.

Now that USB OTG driver supports usb role switch by overriding PHY input
signals (A-Valid, B-Valid and Vbus-Valid), enable it on stm32mp15xx-dkx.
dr_mode needn't to be forced to Peripheral anymore, it is set to OTG in
SoC device tree.
USB role (USB_ROLE_NONE, USB_ROLE_DEVICE, USB_ROLE_HOST) will be provided
by STUSB1600 Type-C controller driver.
This patch depends on "Add STUSB160x Type-C port controller support"
series, which is under review.

Configure I2C5 on stm32mp15 DK boards. It's available and can be used on:
- Arduino connector
- GPIO expansion connector
Keep it disabled by default, so the pins are kept in their initial state to
lower power consumption. This way they can also be used as GPIO.

Some labels follow the *_sleep_pins_* naming scheme, but some also use
*_pins_sleep_*. Because most labels use the former and for uniformity
with variants like sdmmc1_b4_pins_a and sdmmc1_dir_pins_a, adopt the
*_sleep_pins_* scheme throughout.

In the original stm32mp157c.dtsi, the GPU was disabled as some SoC
variants lacked a GPU. We now have separate a dtsi for each SoC
variant and variants without a GPU lack the node altogether.
As we need no board support for using the GPU, enable it by default
and while at it remove the now redundant status = "okay" in existing
board device trees.

On STM32MP1 DK1, DK2, ED1 and EV1 boards, there is only a micro SD socket.
This is also the case on Avenger board.
They don't support the Write Protect pin.
The disable-wp is then added in the SD-cards sdmmc1 nodes.
This avoids executing some code and a warning during driver probe.
