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

2018-04-24drm/rockchip: psr: Sanitize semantics of allow/inhibit APITomasz Figa
Currently both rockchip_drm_psr_activate() and _deactivate() only set the boolean "active" flag without actually making sure that hardware state complies with it. Since we are going to extend the usage of this API to properly lock PSR for the duration of atomic commits, we change the semantics in following way: - a counter is used to track the number of inhibit requests, - PSR is actually disabled in hardware on first inhibit request, - PSR enable work is scheduled on last allow request. The above allows using the API as a way to deterministically synchronize PSR state changes with other DRM events, i.e. atomic commits and cursor updates. As a nice side effect, the naming is sorted out and we have "inhibit" for stopping the software logic and "enable" for hardware state.

2018-04-24drm/rockchip: Restore psr->state when enable/disable psr failedzain wang
If we failed disable psr, it would hang the display until next psr cycle coming. So we should restore psr->state when it failed.

2018-03-08drm/rockchip: analogix_dp: set psr activate/deactivate when enable/disable ↵zain wang
bridge There's a race between when bridge_disable and when vop_crtc_disable are called. If the flush timer triggers a new psr work between these, we will operate eDP without power shutdowned by bridge_disable. In this case, moving activate/deactivate to enable/disable bridge to avoid it.

2016-09-21drm/rockchip: Don't key off vblank for psrSean Paul
Instead of keying off vblank for psr, just flush every time we get an atomic update. This ensures that cursor updates will properly disable psr (without turning vblank on/off), and unifies the paths between fb_dirty and atomic psr enable/disable.

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.
