In an attempt to improve the upstream support of devices powered by the i.MX 6 family of processors, Collabora’s developers improved the brcmfmac open source Broadcom Wi-Fi driver by fixing suspend support for devices that try to save battery life by cutting the power during sleep. They also improved the Panfrost open source driver for modern ARM Mali GPUs, the Hantro VPU codec driver, the Chrome Embedded Controller, as well as the virtual media controller driver (vimc), and paved the way for bus format negotiation between DRM pipeline components.
