2017-10-02ARM: exynos_defconfig: Enable UAS support for Odroid HC1 boardMarek Szyprowski
Odroid HC1 board has built-in JMicron USB to SATA bridge, which supports UAS protocol. Compile-in support for it (instead of enabling it as module) to make sure that all built-in storage devices are available for rootfs. The bridge itself also supports fallback to standard USB Mass Storage protocol, but USB Mass Storage class doesn't bind to it when UAS is compiled as module and modules are not (yet) available.

2017-07-18ARM: exynos_defconfig: Enable locking test optionsKrzysztof Kozlowski
exynos_defconfig, beside serving as a reference config for Exynos-based devices, is used by developers during regular development work. Enabling options responsible for locking tests allows to discover bugs in drivers and mach code earlier. This enables: 1. Detection of sleeping in atomic sections (DEBUG_ATOMIC_SLEEP), 2. Full lockdep (DEBUG_LOCK_ALLOC and PROVE_LOCKING which makes other lock debug entries unneeded), 3. Detection of soft, kernel lockups (SOFTLOCKUP_DETECTOR).

2017-03-07ARM: exynos_defconfig: Increase CONFIG_CMA_SIZE_MBYTES to 96Shuah Khan
Current CMA size of 64 Mbytes is right on the edge of being small when several drivers need to allocate large CMA buffers. For example, if the s5p-mfc driver needs to pre-allocate CMA memory to decode a H.264 1080p video, then there won't be enough CMA memory left for other drivers, such as the exynos-drm driver that may need to allocate GEM buffers for the display manager. Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases such as these.

2016-12-29ARM: exynos_defconfig: Enable IP multicastRobie Basak
Prior to Nikolay's commit dcd87999d, libnss-mdns (eg. to resolve "foo.local" on the LAN using mDNS) worked without CONFIG_IP_MULTICAST defined, but dcd87999d caused it to stop working without having CONFIG_IP_MULTICAST defined explicitly. Since exynos_defconfig did not previously define CONFIG_IP_MULTICAST, mDNS used to work for users building with just exynos_defconfig, but stopped working from dcd87999d.

2015-11-03ARM: exynos_defconfig: enable Exynos DRM Mixer driverAndrzej Hajda
Mixer driver is selected by CONFIG_DRM_EXYNOS_HDMI option. Since Exynos5433 HDMI does not require Mixer. There will be separate options to select Mixer and HDMI. Adding new option to defconfig before Kconfig will allow to keep bisectability.

2015-10-24ARM: exynos_defconfig: Enable WiFi-Ex as a module instead built-inJavier Martinez Canillas
The Marvell WiFi-Ex driver tries to load a firmware on probe. So if the driver is built-in and probed before a firmware is available, this is not loaded and the chip does not work. This happens for example if an initramfs isn't used since the driver is probed before the root filesystem is mounted. Change the default config since the driver isn't needed for machines to boot and is more convenient to have it enabled as a module to avoid requiring an initramfs or to have the firmware built into the kernel.

2015-10-24ARM: exynos_defconfig: Disable simplefb supportJavier Martinez Canillas
The simplefb driver allows the kernel to render on a pre-allocated buffer that's been initialized by firmware before the kernel boots. This option was enabled to have display working on the Exynos5250 Snow Chromebook by commit da9d0fbf5e9a ("ARM: exynos: defconfig update") since proper DRM/KMS support did not exist at that time. But now that the Exynos DRM driver has support for this hardware, there is no need to have simplefb enabled. In fact, if a user has a u-boot that injects the simplefb dev node to the FDT before pass it to the kernel, display won't be properly initialized and only a blank screen will be shown since there isn't a proper handoff from the simplefb driver to the Exynos DRM driver.
