Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

PXA USB controllers
|
|
|
|
OHCI
|
|
|
|
Required properties:
|
|
- compatible: Should be "marvell,pxa-ohci" for USB controllers
|
|
used in host mode.
|
|
|
|
Optional properties:
|
|
- "marvell,enable-port1", "marvell,enable-port2", "marvell,enable-port3"
|
|
If present, enables the appropriate USB port of the controller.
|
|
- "marvell,port-mode" selects the mode of the ports:
|
|
1 = PMM_NPS_MODE
|
|
2 = PMM_GLOBAL_MODE
|
|
3 = PMM_PERPORT_MODE
|
|
- "marvell,power-sense-low" - power sense pin is low-active.
|
|
- "marvell,power-control-low" - power control pin is low-active.
|
|
- "marvell,no-oc-protection" - disable over-current protection.
|
|
- "marvell,oc-mode-perport" - enable per-port over-current protection.
|
|
- "marvell,power_on_delay" Power On to Power Good time - in ms.
|
|
|
|
Example:
|
|
|
|
usb0: ohci@4c000000 {
|
|
compatible = "marvell,pxa-ohci", "usb-ohci";
|
|
reg = <0x4c000000 0x100000>;
|
|
interrupts = <18>;
|
|
marvell,enable-port1;
|
|
marvell,port-mode = <2>; /* PMM_GLOBAL_MODE */
|
|
};
|
|
|
|
UDC
|
|
|
|
Required properties:
|
|
- compatible: Should be "marvell,pxa270-udc" for USB controllers
|
|
used in device mode.
|
|
- reg: usb device MMIO address space
|
|
- interrupts: single interrupt generated by the UDC IP
|
|
- clocks: input clock of the UDC IP (see clock-bindings.txt)
|
|
|
|
Optional properties:
|
|
- gpios:
|
|
- gpio activated to control the USB D+ pullup (see gpio.txt)
|
|
|
|
Example:
|
|
|
|
pxa27x_udc: udc@40600000 {
|
|
compatible = "marvell,pxa270-udc";
|
|
reg = <0x40600000 0x10000>;
|
|
interrupts = <11>;
|
|
clocks = <&pxa2xx_clks 11>;
|
|
gpios = <&gpio 22 GPIO_ACTIVE_LOW>;
|
|
};
