2019-07-26drm/rockchip: Use the helpers for PSRSean Paul
Instead of rolling our own implementation for tracking when PSR should be [in]active, use the new self refresh helpers to do the heavy lifting. Changes in v2: - updated to reflect changes made in the helpers Changes in v3: - use the new atomic hooks to inspect crtc state instead of needing conn state (Daniel) Changes in v4: - Use Laurent's get_new_connector_for_encoder helper (Daniel) - Exit vop disable early if it's already off Changes in v5: - Rebase on latest drm-misc-next - Resolve conflict with s/edp_vsc_psr/dp_sdp/ rename - Resolve conflict with drm_atomic.h header inclusion Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-4-sean@poorly.run Link to v2: https://patchwork.freedesktop.org/patch/msgid/20190326204509.96515-3-sean@poorly.run Link to v3: https://patchwork.freedesktop.org/patch/msgid/20190502194956.218441-9-sean@poorly.run Link to v4: https://patchwork.freedesktop.org/patch/msgid/20190508160920.144739-9-sean@poorly.run Cc: Zain Wang <wzz@rock-chips.com> Cc: Tomasz Figa <tfiga@chromium.org> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Heiko Stuebner <heiko@sntech.de> [seanpaul resolved some conflicts with drmP.h work and Helen's async fixes] Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190611160844.257498-9-sean@poorly.run
2019-07-26drm/rockchip: Check for fast link training before enabling psrSean Paul

2019-07-26drm/panel: jh057n00900: Move panel DSI init to enable()Guido Günther
If the panel is wrapped in a panel_bridge it gets prepar()ed before the upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks are not enabled yet). To avoid this move the panel's first DSI access to enable() so the upstream bridge can prepare the DSI host controller in it's pre_enable(). This is also in line with other panel drivers.

2019-07-26drm/i915/gt: Add to timeline requires the timeline mutexChris Wilson
Modifying a remote context requires careful serialisation with requests on that context, and that serialisation requires us to take their timeline->mutex. Make it so. Note that while struct_mutex rules, we can't create more than one request in parallel, but that age is soon coming to an end. v2: Though it doesn't affect the current users, contexts may share timelines so check if we already hold the right mutex.

There may be cases (like in panel-simple.c) where we have a sane fallback if no timings are specified in the device tree. Let's get rid of the unconditional pr_err(). We can add error messages in individual drivers if it makes sense. NOTE: we'll still print errors if the node is present but there are problems parsing the timings.

We need to drop everything we remove from the tree, whether mnt_has_parent() is true or not. Usually the bug manifests as a slow memory leak (leaked struct mount for initramfs); it becomes much more visible in mount_subtree() users, such as btrfs. There we leak a struct mount for btrfs superblock being mounted, which prevents fs shutdown on subsequent umount.

Thus the caller still see its "cached_state" to be NULL and never free the state allocated under btrfs_lock_and_flush_ordered_range(). As a result, we will see massive state leak with e.g. fstests btrfs/005. Fix this bug by properly handling the pointers.
