Unit testing this in VKMS shows that passing 0 into this function returns -1, which is highly counter- intuitive. Fix it by checking whether the input is >= 0 instead of > 0. Fixes: 64566b5e ("drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil") Signed-off-by:

The Solomon SSD133x controllers (such as the SSD1331) are used by RGB dot matrix OLED panels, add a modesetting pipeline to support the chip family. The SSD133x controllers support 256 (8-bit) and 65k (16-bit) color depths but only the 256-color mode (DRM_FORMAT_RGB332) is implemented for now. Signed-off-by:

Commit 2d23e7d6 ("dt-bindings: display: Add SSD132x OLED controllers") used the wrong properties for width and height, instead of the correct "solomon,width" and "solomon,height" properties. Fix this by adding the vendor prefix to the width and height properties. Fixes: 2d23e7d6 ("dt-bindings: display: Add SSD132x OLED controllers") Reported-by:

inno_hdmi_reset is only ever called when initializing the controller. At this point it’s completely uneccessary to power up the PHY, since all what has to work at this point is the DDC bus. The phy will be powered up correctly when a mode is set in inno_hdmi_encoder_enable and disabled in inno_hdmi_encoder_disable. Set it to LOWER_PWR after resetting the controller. Signed-off-by:

The display controller will always give full range RGB regardless of the mode set, but HDMI requires certain modes to be transmitted in limited range RGB. This is especially required for HDMI sinks which do not support non-standard quantization ranges. This enables color space conversion for those modes and sets the quantization range accordingly in the AVI infoframe. Signed-off-by:

The code to upload infoframes to the controller uses a weird construct which, based on the previous function call return code, will either disable or enable that infoframe. In order to get rid of that argument, let's split the function to disable the infoframe into a separate function and make it obvious what we are doing in the error path. Signed-off-by:

The tmds_rate field in the inno_hdmi structure is used mostly to configure the internal i2c controller divider through a call to the inno_hdmi_i2c_init() function. We can simply make that rate an argument to that function, which also removes a workaround to initialize the divider at probe time when we don't have a mode yet. Signed-off-by:

The controller wants the difference between *total and *sync_start in the HDMI_VIDEO_EXT_*DELAY registers. Otherwise the signal is very unstable for certain non-VIC modes. See downstream commit [0].

In contrast to RK3036, RK312x SoCs have multiple output channels such as RGB (i.e. LVDS TTL), LVDS, DSI and HDMI. In order to support that, this splits output from RK3036 and defines an separate one for RK3126 with the registers required to enable the appropriate output and setup the correct polarity.

These panels are used by Mediatek MT8173 Chromebooks, and they used to work with the downstream v4.19 kernel without any specified delay. Back in the v4.19 kernel, they used the "little white lie" approach, which is making the devicetree claim a specific panel's compatible string for many different panels. That was a common solution before the generic edp-panel driver. After we uprevved the device to a newer kernel and used the edp-panel driver, we saw multiple devices reporting warnings of using an unknown panel and falling back to the conservative timings, which means that they turn on/off much more slowly than they should. We tried to fill in the timings for those panels, but we failed to find all the data sheets for them. Therefore, instead of having them use the default conservative timings, update them with less-conservative timings from other panels of the same vendor. The panels should still work under those timings, and we can save some delays and suppress the warnings. Signed-off-by:

The original rationale for commit cd456f8d ("drm: Restrict stackdepot usage to builtin drm.ko") was that depot_save_stack() (which is what we used back then) wasn't exported. stack_depot_save() (which is what we use now) is exported however, so relax the dependency allow CONFIG_DRM_MM_DEBUG with DRM=m.

The current documentation of drm_atomic_state says that it's the "global state object". This is confusing since, while it does contain all the objects affected by an update and their respective states, if an object isn't affected by this update it won't be part of it. Thus, it's not truly a "global state", unlike object state structures that do contain the entire state of a given object. Reviewed-by:

Commits 63e83c1d ("drm: Consolidate connector arrays in drm_atomic_state"), b8b5342b ("drm: Consolidate plane arrays in drm_atomic_state") and 5d943aa6 ("drm: Consolidate crtc arrays in drm_atomic_state") moved the object pointer and their state pointer to an intermediate structure storing both. The CRTC commit didn't update the doc of the crtcs field to reflect that, and the doc for the planes and connectors fields mention that they are pointers to an array of structures with per-$OBJECT data. The private_objs field was added later on by commit b430c27a ("drm: Add driver-private objects to atomic state") reusing the same sentence than the crtcs field, probably due to copy and paste. While these fields are indeed pointers to an array, each item of that array contain a pointer to the object structure affected by the update, and its old and new state. There's no per-object data there, and there's more than just a pointer to the objects. Let's rephrase those fields a bit to better match the current situation. Acked-by:
