📝 Walkthrough

Walkthrough

Updates kernel release-candidate reference from v7.0-rc6 to v7.0-rc7, adds device-tree configurations for ODROID-M2 board peripherals (USB-C OTG, vu8s display panel), enhances DRM/GEM DMA allocation routines to use dedicated DMA devices, adds USB serial power-management support, and removes a previously applied USB gadget net-device lifecycle patch.

Changes

Cohort / File(s)	Summary
Kernel Configuration config/sources/mainline-kernel.conf.sh	Updated kernel version hooks to reference v7.0-rc7 instead of v7.0-rc6 in upstream release candidate logic and Torvalds mirror overrides.
ODROID-M2 Board Support patch/kernel/archive/rockchip64-7.0/board-odroidm2-*.patch	Added USB Type-C OTG support with PD revision and power-role configuration; introduced vu8s display panel device-tree definitions and ILI9881C panel driver extensions for backlight, DSI, touchscreen, and related pinctrl/clock adjustments.
DRM/GEM Sunxi Patches patch/kernel/archive/sunxi-7.0/patches.armbian/drm-*.patch	Updated GEM DMA allocations, SG table generation, and mmap operations to use dedicated DMA device instead of base DRM device; modified sun4i backend/mixer bind logic to set dedicated DMA device conditionally based on interconnects/iommus properties.
USB Serial/Gadget Patches patch/kernel/archive/sunxi-7.0/patches.megous/fixes-7.0/0018-usb-serial-option-*.patch	Added .reset_resume callback to USB WWAN serial driver power-management ops; removed previously applied USB gadget net-device lifecycle patch (0024) that managed bind counts and device reparenting.
Series Configuration patch/kernel/archive/sunxi-7.0/series.conf	Removed USB gadget patch entry (0024) from kernel patch series list.

Poem

🐰 A kernel hops from rc6 to rc7's light,
ODROID screens glow and USB-C feels right,
DMA devices now flow where they should,
Patches pruned clean, as only we would!
One gadget's gone, but the rest sing in code,
Down the build's merry road! ✨

@mlegenovic can you please check if this Outside diff range comment from Rabbit above makes any sense?

[mlegenovic]

That’s a valid point, but what Rabbit obviously doesn’t know or see is the overlay file in which the property is set and node enabled.

From rockchip-rk3588-odroidm2-display-vu8s.dtso:

fragment@4 {
        target = <&dsi0_panel>;

        __overlay__ {
                status = "okay";
                compatible = "odroid,vu8s";
        };
};

The panel node remains "disabled" until it is configured for a specific display, only then driver can be specified. That’s why I’d ignore the comment.
