155 total contributions across Linux 6.7 through 7.0-rc6, with 76 commits fully authored. The work breaks down into a few clear stories:

The Snapdragon 845 marathon. The heaviest lifting is enabling mainline Linux on real consumer hardware. The Google Pixel 3 and Pixel 3 XL got full device-tree support from scratch. OnePlus 6/6T gained proper display pinctrl, panel regulators, a framebuffer, a notification LED, and WiFi calibration. Similar treatment went to the Xiaomi Mi MIX 2S, Pocophone F1, SHIFT6mq, and Samsung Galaxy S9.

Display driver overhaul. Two panel drivers — sofef00 (OnePlus 6 display) and sw43408 — were significantly refactored: cleaner regulator handling, split command sequences, better compatible strings, and a proper reset function. On top of that, a brand-new S6E3FC2X01 driver landed for the OnePlus 6T's AMOLED panel.

IIO light sensor cleanup. The Dyna Image AL3010, AL3320a, and AL3000a drivers got a thorough polish — regmap migration, better error handling with dev_err_probe, splitting the power toggle into on/off helpers, and removing leftover DRV_NAME definitions.

Device-tree schema work. A generic wireless-controller.yaml was introduced and adopted by three wireless drivers. Several old .txt bindings (ad5820, gpio-fan, iommu-v0) were converted to proper YAML schemas, and cross-platform DTS bugs were fixed across Rockchip, i.MX8, Marvell, and Freescale targets.

Bug hunting. Seven reported bugs, including triggering a revert series of USB gadget NCM regressions that had broken Ethernet-over-USB functionality.
