This v3 version have splited an common PSR driver for Rockchip, which is biggest changes from v2. This thread is based on Mark's RK3399 VOP thread[0] and my RK3399 eDP thread[1]. [0]: https://patchwork.kernel.org/patch/8886041/ [1]: https://patchwork.kernel.org/patch/9204497/ Thanks, - Yakir Changes in v3: - Remove the notify for waiting line_flag event (Daniel) - implement the 'fb->dirty' callback function (Daniel) - avoid to use notify to acqiure for vact event (Daniel) - split the psr flow into an common abstracted PSR driver - Export the 'rockchip_drm_wait_line_flag' symbol, and document it. - Add 'line_flag_num_0' for RK3288/RK3036 - remove psr_active() callback which introduce in v2 - split analogix_dp_enable_psr(), make it more clearly analogix_dp_detect_sink_psr() analogix_dp_enable_sink_psr() - remove some nosie register setting comments - split the common psr logic into a seperate driver, make this to a simple sub-psr device driver. Changes in v2: - Introduce in v2, split VOP line flag changes out - introduce in v2, splite the common Analogix DP changes out - remove vblank notify out (Daniel) - create a psr_active() callback in vop data struct.
