The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too. Signed-off-by:

The ADV7511 has four 256-byte maps that can be accessed via the main I2C ports. Each map has it own I2C address and acts as a standard slave device on the I2C bus. Allow a device tree node to override the default addresses so that address conflicts with other devices on the same bus may be resolved at the board description level. Signed-off-by:

Note that a pile of drivers don't seem to take implicit fencing into account, or at least don't call drm_atoimc_set_fence_for_plane(). Cc'ing relevant people, or at least some. Some drivers also look like they don't disable implicit fencing (e.g. amdgpu) because the explicit fences and implicit fences are handled by entirely independent code paths. I also wonder whether we shouldn't just make the recommended helpers the default ones, since a lot of drivers don't bother to handle the implicit fences at all it seems. The helpers won't blow up even for non-GEM drivers or GEM drivers which don't fill out the gem bo pointers in struct drm_framebuffer. v2: Comments from Eric.

The Lenovo Ideapad Mixx 320 laptop uses a portrait LCD panel, add a quirk for this. While at it instead of duplicating the same drm_dmi_panel_orientation_data for 3 laptops add a generic lcd800x1280_rightside_up orientation_data and use that for all 3 (including the new Mixx 320 entry).

It is not used anymore after last changes and it was not even correct to begin with as it assumed a 1:1 relation between a CRTC and encoder, while in fact a CRTC can be attached to multiple encoders. Signed-off-by:

Currently PSR flush is triggered from CRTC's .atomic_begin() callback, which is executed after modeset disables and enables and before plane updates are committed. Since PSR flush and re-enable can be triggered asynchronously by external sources (input event, delayed work), it can race with hardware programming done in the aforementioned stages. This patch blocks the PSR completely before hardware programming part begins and unblock after it ends. This relies on reference counted PSR disable introduced with previous patch. Cc: Kristian H.

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. Signed-off-by:

The first time after we call rockchip_drm_do_flush() after rockchip_drm_psr_register(), we go from PSR_DISABLE to PSR_FLUSH. The difference between PSR_DISABLE and PSR_FLUSH is whether or not we have a delayed work pending - PSR is off in either state. However psr_set_state() only catches the transition from PSR_FLUSH to PSR_DISABLE (which never happens), while going from PSR_DISABLE to PSR_FLUSH triggers a call to psr->set() to disable PSR while it's already disabled. This triggers the eDP PHY power-on sequence without being shut down first and this seems to occasionally leave the encoder unable to later enable PSR. Let's just simplify the state machine and simply consider PSR_DISABLE and PSR_FLUSH the same state. Signed-off-by:

Some of the platform-specific stuff in rockchip_dp_poweron() needs to happen before the generic code. Some needs to happen after. Let's split the callback in two. Specifically we can't start doing PSR work until _after_ the whole controller is up, so don't set the enable until the end. Cc: Kristian H. Kristensen <hoegsberg@chromium.org> Signed-off-by:

Some encoder have a crc verification check, crc check fail if input and output data is not equal. That means encoder input and output need use same color depth, vop can output 10bit data to encoder, but some panel only support 8bit depth, that would make crc check die. So pre dither down vop data to 8bit if panel's bpc is 8. Signed-off-by:

The comments in analogix_dp_init_aux() claim that we're disabling aux channel retries, but then right below it for Rockchip it sets them to 3. If we actually need 3 retries for Rockchip then we could adjust the comment, but it seems more likely that we want the same retry behavior across all platforms.

The code in analogix_dp_transfer() that was supposed to print out: AUX CH error happened Was actually dead code. That's because the previous check (whether the interrupt status indicated any errors) would have hit for all errors anyway. Let's combine the two error checks so we can actually see AUX CH errors. We'll also downgrade the message to a warning since some of these types of errors might be expected for some displays. If this gets too noisy we can downgrade again to debug.

The current user of the analogix power_off is "analogix_dp-rockchip". That driver does this: - deactivate PSR - turn off a clock Both of these things (especially deactive PSR) should be done before we turn the PHY power off and turn off analog power. Let's move the callback up. Note that without this patch (and with https://patchwork.kernel.org/patch/9553349/ [seanpaul: this patch was not applied, but it seems like the race can still occur]), I experienced an error in reboot testing where one thread was at: rockchip_drm_psr_deactivate rockchip_dp_powerdown analogix_dp_bridge_disable drm_bridge_disable ...and the other thread was at: analogix_dp_send_psr_spd analogix_dp_enable_psr analogix_dp_psr_set psr_flush_handler The flush handler thread was finding AUX channel errors and eventually reported "Failed to apply PSR", where I had a kgdb breakpoint. Presumably the device would have eventually given up and shut down anyway, but it seems better to fix the order to be more correct. Cc: Kristian H. Kristensen <hoegsberg@chromium.org> Signed-off-by:

It's too early to detect fast link training, if other step after it failed, we will set fast_link flag to 1, and retry set_bridge again. In this case we will power down and power up panel power supply, and we will do fast link training since we have set fast_link flag to 1. In fact, we should do full link training now, not the fast link training. So we should move the fast link detection at the end of set_bridge. Cc: Tomasz Figa <tfiga@chromium.org> Signed-off-by:

Enhanced mode is required by the eDP 1.2 specification, and not doing it early could result in a period of time where we have a link transmitting idle packets without it.
