Now that we are "extracting" the cdclk frequency on ILK-IVB we can also simplify ilk_get_aux_clock_divider() to calculate the divider based on cdclk instead of hardcoding the values.

We don't currently have cdclk extraction code for 965g,snb,ivb. Let's assume 400 MHz until we know better. That seems to match hints in various vague documents. Whether that's good enough is not entirely clear.

Based on the BIOS DP A AUX 2x clock divider the cdclk frequency on ILK is 450Mhz. At least that holds on my ILK and it matches how we program the divider. Supposedly cdclk is 400MHz on SNB and IVB, again based on the AUX 2x clock divider. Note that I don't have a SNB or IVB machine with eDP so I couldn't verify what the BIOS used, so this notion is purely based on our current code, Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

ns2501 requires the DVO 2x clock before it will respond to i2c access, so make sure the clock is enabled when we try to initialize the encoder.

After the GPU has wedged we can't turn on the overlay anymore. Only mark it as active if we succeed in allocating ring space. This prevents a WARN (previous;y a BUG) during driver unload if we attempted to use the overlay after the GPU had already wedged.

Pull ARM SoC fixes from Olof Johansson: "The latest and greatest fixes for ARM platform code. Worth pointing out are: - Lines-wise, largest is a PXA fix for dealing with interrupts on DT that was quite broken. It's still newish code so while we could have held this off, it seemed appropriate to include now - Some GPIO fixes for OMAP platforms added a few lines. This was also fixes for code recently added (this release). - Small OMAP timer fix to behave better with partially upstreamed platforms, which is quite welcome. - Allwinner fixes about operating point control, reducing overclocking in some cases for better stability. plus a handful of other smaller fixes across the map" * tag 'armsoc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64: juno: Fix misleading name of UART reference clock ARM: dts: sunxi: Remove overclocked/overvoltaged OPP ARM: dts: sun4i: a10-lime: Override and remove 1008MHz OPP setting ARM: socfpga: dts: fix spi1 interrupt ARM: dts: Fix gpio interrupts for dm816x ARM: dts: dra7: remove ti,hwmod property from pcie phy ARM: OMAP: dmtimer: disable pm runtime on remove ARM: OMAP: dmtimer: check for pm_runtime_get_sync() failure ARM: OMAP2+: Fix socbus family info for AM33xx devices ARM: dts: omap3: Add missing dmas for crypto ARM: dts: rockchip: disable gmac by default in rk3288.dtsi MAINTAINERS: add rockchip regexp to the ARM/Rockchip entry ARM: pxa: fix pxa interrupts handling in DT ARM: pxa: Fix typo in zeus.c ARM: sunxi: Have ARCH_SUNXI select RESET_CONTROLLER for clock driver usage

The UART reference clock speed is 7273.8 kHz, not 72738 kHz. Dots aren't usually used in node names even though ePAPR permits them. However, this can easily be avoided by expressing the frequency in Hz, not kHz. This patch changes the name to refclk7273800hz, reflecting the actual clock speed.

To allow for views where the view type is not defined by the view type only, like it is in stereo or rotated 90 degree view, change the semantic to require the whole view structure for comparison when we match a GGTT view. This allows including parameters like offset to be included in the view which is useful for eg. partial views. v3: - Rely on ggtt_view type being 0 for non-GGTT vma's, which equals to I915_GGTT_VIEW_NORMAL. (Daniel Vetter) - Do not use potentially slower comparison when we only want to know if something is or is not a normal view. - Rebase on top of rotated view patches. Add rotated view singleton. - If one view is missing in comparison they're equal only if both are missing. v4: - Use comparison helper in obj_to_ggtt_view too. (Tvrtko Ursulin) - Do WARN_ON if one view is NULL.
