2017-04-11drm/i915/dp: do not limit rate seek when not neededJani Nikula
In link training fallback, we're trying to find a rate that we know is in a sorted array of common link rates. We don't need to limit the array using the max rate. For test request, the DP CTS doesn't say we should limit the rate based on earlier fallback. This lets us get rid of intel_dp_link_rate_index() and use intel_dp_rate_index() instead.

2017-04-11drm/i915/dp: cache common rates with sink ratesJani Nikula
Now that source rates are static and sink rates are updated whenever DPCD is updated, we can do and cache the intersection of them whenever sink rates are updated. This reduces code complexity, as we don't have to keep calling the functions to intersect. We also get rid of several common rates arrays on stack. Limiting the common rates by a max link rate can be done by picking the first N elements of the cached common rates. v2: get rid of the local common_rates variable (Manasi) v3: don't clobber cached eDP rates on short pulse (Ville) Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/e3b287e8cb6559b1f8fd4e80b78a8d22f1802eb7.1491485983.git.jani.nikula@intel.com

Since the sandybridge_pcode_read() may be called from skl_pcode_request() inside an atomic context (with preempt disabled), we should avoid hitting any sleeping paths. Currently is being called with a 500ms timeout, irrespective of being inside an atomic context or not. This is reduced down to 500us to play nice with the atomic context, and that appears to be sufficient to keep BAT happy (we have a DRM_ERROR should it timeout), i.e. we do not see any 500us pcode timeouts for normal use. So leave it as a pure spin without having to introduce new code paths to separate atomic/normal contexts.

2017-04-11pinctrl: cherryview: Add a quirk to make Acer Chromebook keyboard work againMika Westerberg
After commit 47c950d10202 ("pinctrl: cherryview: Do not add all southwest and north GPIOs to IRQ domain") the driver does not add all GPIOs to the irqdomain. The reason for that is that those GPIOs cannot generate IRQs at all, only GPEs (General Purpose Events). This causes Linux virtual IRQ numbering to change. However, it seems some CYAN Chromebooks, including Acer Chromebook hardcodes these Linux IRQ numbers in the ACPI tables of the machine. Since the numbering is different now, the IRQ meant for keyboard does not match the Linux virtual IRQ number anymore making the keyboard non-functional. Work this around by adding special quirk just for these machines where we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell based machines will not be affected by the change.

The following warning results from holding a lane spinlock, preempt_disable(), or the btt map spinlock and then trying to take the reconfig_mutex to walk the poison list and potentially add new entries.

2017-04-10drm: dw-hdmi: Implement the mode_fixup drm helperRomain Perier
This helper is supposed to validate or reject the modeline before it applied by the mode setting. Currently this function has been dropped, it was previously set to a dummy function that always returned true. For both cases, this means that userspace can ask for a bad modeline that will be always accepted. On some platforms, like Rockchip, the drm dw_hdmi-rockchip variant driver already implements the atomic_check drm helper, so mode_fixup cannot be handled and implemented there (as drm_atomic_helper relies on either atomic_check or mode_fixup). This commit implements this helper. It only checks that this mode is correct from the connector point of view.
