2016-08-24io-mapping: Fixup for different names of writecombineDaniel Vetter
Somehow architectures can't agree on this. And for good measure make sure we have a fallback which should work everywhere (fingers crossed). v2: Make it compile properly, needs a defined() for the #elif.

2016-08-24io-mapping.h: s/PAGE_KERNEL_IO/PAGE_KERNEL/Chris Wilson
PAGE_KERNEL_IO is an x86-ism. Though it is used to define the pgprot_t used for the iomapped region, it itself is just PAGE_KERNEL. On all other arches, PAGE_KERNEL_IO is undefined so in a general header we must refrain from using it. v2: include pgtable for pgprot_combine() Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Fixes: cafaf14a5d8f ("io-mapping: Always create a struct to hold metadata about the io-mapping") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: linux-mm@kvack.org Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20160823155024.22379-1-chris@chris-wilson.co.uk (cherry picked from commit ac96b5566926af83463ddcf4655856033c092f26)
2016-08-24drm/gma500: remove unnecessary config_enabled() guardMasahiro Yamada
Commit d112a8163f83 ("gma500/cdv: Add eDP support") replaced the code inside this if-conditional with gma_backlight_set(), which becomes a nop stub if CONFIG_BACKLIGHT_CLASS_DEVICE is disabled. So, there is no need to guard the caller with config_enabled(). Note: This is one of remaining TODOs to deprecate config_enabled() macro.

2016-08-24drm/doc: Document uapi requirements in DRMDaniel Vetter
Everyone knows them, except all the new folks joining from the ARM side haven't lived through all the pain of the past years and are entirely surprised when I raise this.

2016-08-23drm/rockchip: add an common abstracted PSR driverYakir Yang
The PSR driver have exported four symbols for specific device driver, and it's safe to call them in interrupt context: - rockchip_drm_psr_register() - rockchip_drm_psr_unregister() - rockchip_drm_psr_enable() - rockchip_drm_psr_disable() - rockchip_drm_psr_flush() Encoder driver should call the register/unregister interfaces to hook itself into common PSR driver, encoder have implement the 'psr_set' callback which use the set PSR state in hardware side. Crtc driver would call the enable/disable interfaces when vblank is enable/disable, after that the common PSR driver would call the encoder registered callback to set the PSR state. Fb driver would call the flush interface in 'fb->dirty' callback, this helper function would force all PSR enabled encoders to exit from PSR for 3 seconds.
