Add a freestanding function argument to drm_mode_parse_cmdline_options() similar to how drm_mode_parse_cmdline_extra() already has this. This is a preparation patch for allowing parsing of stand-alone options without a mode before them, e.g.: video=HDMI-1:margin_right=14,... Acked-by:

Refactor drm_mode_parse_cmdline_options() so that it takes a pointer to the first option, rather then a pointer to the ',' before the first option. This is a preparation patch for allowing parsing of stand-alone options without a mode before them, e.g.: video=HDMI-1:margin_right=14,... Acked-by:

Hans de Goede authored
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:

We are not supposed to modify the passed in string, make char pointers used in drm_mode_parse_cmdline_options() const char * where possible. 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:

Some dw-mipi-dsi instances in Rockchip SoCs use external dphys. In these cases the needs clock will also be generated externally so these don't need the ref-clock as well. 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:

The GMA500 driver is using the legacy GPIO API to fetch three optional display control GPIO lines from the SFI description used by the Medfield platform. Switch this over to use GPIO descriptors and delete the custom platform data. We create three new static locals in the tc35876x bridge code but it is hardly any worse than the I2C client static local already there: I tried first to move it to the DRM driver state container but there are workarounds for probe order in the code so I just stayed off it, as the result is unpredictable. People wanting to do a more throrugh and proper cleanup of the GMA500 driver can work on top of this, I can't solve much more since I don't have access to the hardware, I can only attempt to tidy up my GPIO corner.

Thomas Zimmermann authored
Udl has a single display pipeline with a primary plane; perfect for simple-pipe helpers. Convert it over. The old encoder and CRTC code becomes unused and obsolete. Exported formats for the primary plane are RGB565 and XRGB8888, with the latter being emulated. The 16-bit format is the default and what is used when communicating with the device. This patch enables atomic modesetting for udl devices. v3: * remove unused field crtc from struct udl_device * set crtc_state->no_vblank at beginning of enable() v2: * move suspend/resume changes into separate patch * remove non-atomic code Signed-off-by:
