The board has: H616 SoC 1GB of RAM AXP313A PMIC And the actual boards that CB1 plugs in are just extension to it with ports and thus are not split in DT. Boards have: 4x (3x for Manta boards) USB and 1 USB OTG. SDcard slot for loading images. Ethernet port wired to the internal PHY. 2x HDMI 2.0. Power and Status LEDs.

Looking at board photo, it surely looks like this board has same USB design as Zero2. But if that's true, you shouldn't enable OHCI0 and EHCI0 nodes. Is there any board schematic publicly available for this board?

It's possible that you have to update this table: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/ drivers/bus/sunxi-rsb.c?h=v6.1-rc5#n528 If still doesn't work, you have to remove RSB support in PMIC driver.

From what i tried to find there isnt. Maybe i did not look hard enough but i do not have one. All i go from here is the downstream kernel. Biqu itself released datasheets for AXP305 and AXP313A. Where the AXP313A is actually used on the board and uses the AXP1530 driver thats found in downstream which did include RSB support. So it looks like to me that AXP313A is just a rebrand of AXP1530. And all other references to downstream kernels i found about AXP1530 or AXP313A used I2C to communicate with the chip. So in this state i would be happy to drop the RSB support from the driver as there seems to be no use for it and leave I2C in. This would be done in V2 alongside any other requested changes > > Best regards, > Jernej > >> >> >> + reg = <0x36>; >> >> + wakeup-source; >> >> + >> >> + regulators{ >> >> + reg_dcdc1: dcdc1 { >> >> + regulator-name = "axp1530- > dcdc1"; >> >> + regulator-min-microvolt = >> > >> > <500000>; >> > >> >> + regulator-max-microvolt = >> > >> > <3400000>; >> > >> >> + regulator-step-delay-us = <25>; >> >> + regulator-final-delay-us = <50>; >> >> + regulator-always-on; >> >> + }; >> >> + >> >> + reg_dcdc2: dcdc2 { >> >> + regulator-name = "axp1530- > dcdc2"; >> >> + regulator-min-microvolt = >> > >> > <500000>; >> > >> >> + regulator-max-microvolt = >> > >> > <1540000>; >> > >> >> + regulator-step-delay-us = <25>; >> >> + regulator-final-delay-us = <50>; >> >> + regulator-ramp-delay = <200>; >> >> + regulator-always-on; >> >> + }; >> >> + >> >> + reg_dcdc3: dcdc3 { >> >> + regulator-name = "axp1530- > dcdc3"; >> >> + regulator-min-microvolt = >> > >> > <500000>; >> > >> >> + regulator-max-microvolt = >> > >> > <1840000>; >> > >> >> + regulator-step-delay-us = <25>; >> >> + regulator-final-delay-us = <50>; >> >> + regulator-always-on; >> >> + }; >> >> + >> >> + reg_aldo1: ldo1 { >> >> + regulator-name = "axp1530- > aldo1"; >> >> + regulator-min-microvolt = >> > >> > <1800000>; >> > >> >> + regulator-max-microvolt = >> > >> > <1800000>; >> > >> >> + regulator-step-delay-us = <25>; >> >> + regulator-final-delay-us = <50>; >> >> + regulator-always-on; >> >> + }; >> >> + >> >> + reg_dldo1: ldo2 { >> >> + regulator-name = "axp1530- > dldo1"; >> >> + regulator-min-microvolt = >> > >> > <3300000>; >> > >> >> + regulator-max-microvolt = >> > >> > <3300000>; >> > >> >> + regulator-step-delay-us = <25>; >> >> + regulator-final-delay-us = <50>; >> >> + regulator-always-on; >> >> + }; >> >> + }; >> >> + }; >> >> +}; >> >> + >> >> +&uart0 { >> >> + pinctrl-names = "default"; >> >> + pinctrl-0 = <&uart0_ph_pins>; >> >> + status = "okay"; >> >> +}; >> >> + >> >> +&usbotg { >> >> + /* >> >> + * PHY0 pins are connected to a USB-C socket, but a role >> switch >> >> + * is not implemented: both CC pins are pulled to GND. >> >> + * The VBUS pins power the device, so a fixed peripheral mode >> >> + * is the best choice. >> >> + * The board can be powered via GPIOs, in this case port0 >> *can* >> >> + * act as a host (with a cable/adapter ignoring CC), as VBUS >> is >> >> + * then provided by the GPIOs.
