2022-11-15arm64: dts: verdin-imx8mp: disable usb port power controlMarcel Ziswiler
Disable port power control on Verdin USB_1/2 as we use regular fixed-regulators with Verdin USB_1/2_EN as enable GPIOs. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Upstream-Status: Submitted [https://lore.kernel.org/all/20221102131203.35648-1-marcel@ziswiler.com/]
2022-11-15arm64: dts: verdin-imx8mp: add usb_1 over-current detectionMarcel Ziswiler
Add Verdin USB_1 over-current detection functionality via Verdin USB_1_OC# (SODIMM 157) being active-low and removing its previous gpio_hog3 mapping.

2022-11-15arm64: dts: verdin-imx8mp: remove usb_2 over-current detection disablingMarcel Ziswiler
The disable-over-current property is only applicable for the ci-hdrc-usb2 and dwc2 drivers while the i.MX 8M Plus integrates dwc3 IP. Therefore remove this property which does not really serve any purpose here.

2022-11-15arm64: dts: verdin-imx8mp: improve pinctrl for vbus-suppliesMarcel Ziswiler
As we are using two fixed regulators for Verdin USB_1_EN (SODIMM 155) and Verdin USB_2_EN (SODIMM 185), those should be muxed as GPIOs rather than OTG_PWR.

2022-11-15arm64: dts: imx8mp-verdin: fix ctrl_sleep_mociMax Krummenacher
The GPIO signaling ctrl_sleep_moci is currently handled as a gpio hog. But the gpio-hog node is made a child of the wrong gpio controller. Move it to the node representing gpio4 so that it actually works. Without this carrier board components jumpered to use the signal are unconditionally switched off.

2022-11-15arm64: dts: imx8mp-verdin: delete unneeded reserved-memory nodesMax Krummenacher
We don't use the tuning tool, whatever that is. So remove the reserved-memory region dedicated to the ISP and make another 256MB of memory available. Upstream-Status: Innapropriate [ISP doesn't reserve memory in upstream] Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

2022-11-15arm64: dts: freescale: add initial support for verdin imx8m plusMarcel Ziswiler
This patch adds the device tree to support Toradex Verdin iMX8M Plus [1] a computer on module which can be used on different carrier boards. The module consists of an NXP i.MX 8M Plus family SoC (either i.MX 8M Plus Quad or 8M Plus QuadLite), a PCA9450C PMIC, a Gigabit Ethernet PHY, 1, 2, 4 or 8 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an RX8130 RTC, an optional I2C temperature sensor plus an optional Bluetooth/Wi-Fi module. Anything that is not self-contained on the module is disabled by default. The device tree for the Dahlia includes the module's device tree and enables the supported peripherals of the carrier board. The device tree for the Verdin Development Board includes the module's device tree as well as the Dahlia one as it is a superset and supports almost all peripherals available. So far there is no display functionality supported at all but basic console UART, USB host, eMMC and Ethernet functionality work fine.
