In drm_dev_init, parent is checked for NULL via assert after checked in devm_drm_dev_init(). The patch removes the duplicate check and replaces the assertion with WARN_ON. Further, it returns -EINVAL consistent with the usage in devm_drm_dev_init. Signed-off-by:

Add new struct drm_device based logging macros modeled after the core kernel device based logging macros. These would be preferred over the drm printk and struct device based macros in drm code, where possible. We have existing drm specific struct device based logging functions, but they are too verbose to use for two main reasons: * The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS(). * The use of struct device over struct drm_device is too generic for most users, leading to an extra dereference. For example: DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n"); vs. drm_dbg_kms(drm, "Hello, world\n"); It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be less readable than lowercase. Some names are changed from old DRM names to be based on the core kernel logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG -> dbg. Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use (DRM_DEBUG is used widely in drivers though it's supposed to be a core debugging category), they are named as drm_dbg_core and drm_dbg, respectively. The drm_err and _once/_ratelimited variants no longer include the function name in order to be able to use the core device based logging macros. Arguably this is not a significant change; error messages should not be so common to be only distinguishable by the function name. Ratelimited debug logging macros are to be added later.

fb_get_options() will return fb_mode_option if no video=<connector-name> argument is present on the kernel commandline, so there is no need to also do this in drm_mode_parse_command_line_for_connector() as our only caller uses fb_get_options() to get the mode_option argument.

Sometimes we want to override a connector's panel_orientation from the kernel commandline. Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).

Some options which can be specified on the commandline, such as margin_right=..., margin_left=..., etc. are applied not only to the specified mode, but to all modes. As such it would be nice if the user can simply say e.g. video=HDMI-1:margin_right=14,margin_left=24,margin_bottom=36,margin_top=42 This commit refactors drm_mode_parse_command_line_for_connector() to add support for this, and as a nice side effect also cleans up the function a bit.

Hans de Goede authored
drm_connector_get_cmdline_mode() calls drm_mode_parse_command_line_for_connector() with &connector->cmdline_mode as mode argument, so anything which we store in the mode arguments gets kept even if we return false. Avoid storing a possibly false-postive bpp/refresh_specified setting in connector->cmdline_mode by moving the setting of these to after successful parsing of the bpp/refresh parts of the video= argument.

Before this commit it was impossible to combine an extra mode argument specified directly after the resolution with an option, e.g. video=HDMI-1:720x480e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted. This commit fixes this by setting parse_extras to true in this case, so that drm_mode_parse_cmdline_res_mode() parses the extra arguments directly after the resolution. Acked-by:

Before this commit it was impossible to add an extra mode argument after a bpp or refresh specifier, combined with an option, e.g. video=HDMI-1:720x480-24e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted. This commit fixes this by fixing the length calculation if extras_ptr is set to stop the extra parsing at the start of the options (stop at the ',' options_ptr points to). Acked-by:

Hans de Goede authored
Before this commit, if the last option of a video=... option is for example "rotate" without a "=<value>" after it then delim will point to the terminating 0 of the string, and value which is sets to <delim + 1> will point one position past the end of the string. This commit fixes this by enforcing that the contents of delim equals '=' as it should be for options which take a value, this check is done in a new drm_mode_parse_cmdline_int helper function which factors out the common integer parsing code for all the options which take an int.

While the common case is that the dsi controller uses an internal dphy, accessed through the phy registers inside the dsi controller, there is also the possibility to use a separate dphy from a different vendor. One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy, so add the support for handling such a constellation, including the pll also getting generated inside that external phy. changes in v5: - rebased on top of 5.5-rc1 - merged with dsi timing change to prevent ordering conflicts Signed-off-by:

If implementation-specific phy_ops need to be defined they probably should be enabled before trying to talk to the panel and disabled only after the panel was disabled. Right now they are enabled last and disabled first, so might make it impossible to talk to some panels - example for this being the px30 with an external Innosilicon dphy that needs the phy to be enabled to transfer commands to the panel. So move the calls appropriately. changed in v5: - rebased on top of 5.5-rc1 - merged with dsi timing change to prevent ordering conflicts Signed-off-by:

Heiko Stuebner authored
The timing values for dw-dsi are often dependent on the used display and according to Philippe Cornu will most likely also depend on the used phy technology in the soc-specific implementation. To solve this and allow specific implementations to define them as needed add a new get_timing callback to phy_ops and call this from the dphy_timing function to retrieve the necessary values for the specific mode. Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling according to the phy speed, while STM seems to be ok with static values. changes in v5: - rebase on 5.5-rc1 - merge into px30 dsi series to prevent ordering conflicts changes in v4: - rebase to make it directly fit on top of drm-misc-next after all changes in v3: - check existence of phy_ops->get_timing in __dw_mipi_dsi_probe() - emit actual error when get_timing() call fails - add tags from Philippe and Yannick changes in v2: - add driver-specific handling, don't force all bridge users to use the same timings, as suggested by Philippe Suggested-by:
