This is a Q8 format 7 inch tablet with an Allwinner A13 SoC. It has 512MB DRAM, 4GB NAND flash, an accelerometer, camera, RTL8188-based WiFi, and micro SD slot for external storage. It is likely made by a subsidiary of Hanns.G (Hannstar). Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

The current GPL only licensing on the DTSI makes it very impractical for other software components licensed under another license. In order to make it easier for them to reuse our device trees, relicense our DTSI first under a GPL/X11 dual-license. Hopefully, the DTS will follow soon.

This was caused by commit 5a8da524 ("ARM: dts: exynos5420: add dsi node"), which conflicted with d51cad7d ("ARM: dts: remove display power domain for exynos5420"). The DTS addition should never have been merged through the DRM tree in the first place, and it lacked an ack from the platform maintainer (who would have known that the disp_pd reference got removed).

Due to recent consolidation of Exynos suspend and cpuidle code, some parts of suspend and resume sequences are executed two times, once from exynos_pm_syscore_ops and then from exynos_cpu_pm_notifier() and thus it breaks suspend, at least on Exynos4-based boards. In addition, simple core power down from a cpuidle driver could, in case of CPU 0 could result in calling functions that are specific to suspend and deeper idle states. This patch fixes the issue by moving those operations outside the CPU PM notifier into suspend and AFTR code paths. This leads to a bit of code duplication, but allows additional code simplification, so in the end more code is removed than added.

Load purgatory code in RAM and relocate it based on the location. Relocation code has been inspired by module relocation code and purgatory relocation code in kexec-tools. Also compute the checksums of loaded kexec segments and store them in purgatory. Arch independent code provides this functionality so that arch dependent bootloaders can make use of it. Helper functions are provided to get/set symbol values in purgatory which are used by bootloaders later to set things like stack and entry point of second kernel etc. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Cc: Borislav Petkov <bp@suse.de> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: H.
