Another two months and a half have passed, Linux Kernel v4.18 has been released, which means it's time to stop along the way and make a little retrospective. This time around, seven Collaborans have contributed to the kernel, authoring 62 commits. Let's take a look at what we've been working on!

Graphics:

• Daniel Stone continued his cleanup work on the DRM framework, specifically in the amdgpu, radeon and tegra drivers.
• Gustavo Padovan continued his effort of supporting async-updates in the DRM atomic API. This time, he contributed a commit which adds async-update support for the vc4 driver for Broadcom devices.
• Emil Velikov fixed a bug in the error path in the msm DRM driver for Snapdragon devices.

Chromebook support:

• As part of our work to improve Linux support for Chromebook devices, Enric Balletbò worked on improving the support for PWM-powered blacklight devices. Enric also submitted a patchset including cleanups, improvements, and bug fixes for Rockchip DRM driver and PSR support.
• Ezequiel Garcia contributed a series to improve the defconfig for Rockchip RK3399 platforms.

Here, there and everywhere:

• Ezequiel Garcia added MMC/SD support on the Creator CI20 board, which is powered by a MIPS JZ4780 SoC.
• Sebastian Reichel fixed a boot regression on GE Healthcare CARESCAPE™ ONE Monitor, caused by an interrupt storm in Atmel's MXT touch driver.
• Sebastian Reichel did cleanup work on NXP/Freescale's serial controller imx driver.
• Sebastian Reichel continued his task of maintaining the power-supply subsystem.
• Tomeu Vizoso contributed a change to the dwc2 USB driver, fixing an issue in the error path.
• Ana Guerrero Lopez, who recently joined our team, tested a patch to support realtek's UVC 1.5 device. This is needed to enable the cameras embedded on some laptops, such as some Dell XPS models.
