Fix commit '46a30aca7f5c MLK-20052 L2 Cache TEE/Linux shared mutex' when CONFIG_OPTEE is not defined. Compiler warning: | arch/arm/mm/cache-l2x0.c:151:12: warning: ‘l2c_set_mutex’ defined but not used [-Wunused-function] fns.set_mutex and l2c_set_mutex() are guarded by CONFIG_OPTEE.

2020-02-12drm/mxsfb: don't manipulate with clock inside ISROleksandr Suvorov
iMX8 manages clocks with system controller (sc) using RPC. Using RPC procedures from interrupt context leads kernel crash. Remove enabling/disabling clock in interrupt handler. Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
2020-02-12drm/mxsfb: grab the pm->sync() reference on probingOleksandr Suvorov
The mxsfb driver doesn't have a real consumer. This leads the power domains of eLCDIF to off right after device probing. It is required to get the reference counter to prevent this behavior. Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

2020-02-12drm/atomic: make drm_atomic_helper_wait_for_vblanks more agressiveLucas Stach
drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.

2020-02-12drm/vblank: Allow dynamic per-crtc max_vblank_countVille Syrjälä
On i965gm we need to adjust max_vblank_count dynamically depending on whether the TV encoder is used or not. To that end add a per-crtc max_vblank_count that takes precedence over its device wide counterpart. The driver can now call drm_crtc_set_max_vblank_count() to configure the per-crtc value before calling drm_vblank_on(). Also looks like there was some discussion about exynos needing similar treatment. v2: Drop the extra max_vblank_count!=0 check for the WARN(last!=current), will take care of it in i915 code (Daniel) WARN_ON(!inmodeset) (Daniel) WARN_ON(dev->max_vblank_count) Pimp up the docs (Daniel) Cc: stable@vger.kernel.org Cc: Inki Dae <inki.dae@samsung.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181127182004.28885-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
