2019-12-18drm/bridge: lvds-codec: Simplify panel DT node localisationFabrizio Castro
The probe function needs to get ahold of the panel device tree node, and it achieves that by using a combination of of_graph_get_port_by_id, of_get_child_by_name, and of_graph_get_remote_port_parent. We can achieve the same goal by replacing those calls with a call to of_graph_get_remote_node these days.

2019-12-18udmabuf: fix dma-buf cpu accessGurchetan Singh
I'm just going to put Chia's review comment here since it sums the issue rather nicely: "(1) Semantically, a dma-buf is in DMA domain. CPU access from the importer must be surrounded by {begin,end}_cpu_access. This gives the exporter a chance to move the buffer to the CPU domain temporarily. (2) When the exporter itself has other means to do CPU access, it is only reasonable for the exporter to move the buffer to the CPU domain before access, and to the DMA domain after access. The exporter can potentially reuse {begin,end}_cpu_access for that purpose. Because of (1), udmabuf does need to implement the {begin,end}_cpu_access hooks. But "begin" should mean dma_sync_sg_for_cpu and "end" should mean dma_sync_sg_for_device. Because of (2), if userspace wants to continuing accessing through the memfd mapping, it should call udmabuf's {begin,end}_cpu_access to avoid cache issues."

2019-12-17drm/mcde: Some fixes to handling video modeLinus Walleij
The video DSI mode had not really been tested. These fixes makes it more likely to work on real hardware: - Put the active width (x width) in the right bits and the VSA (vertical sync active) in the right bits (those were swapped). - Calculate the packet sizes in bytes as in the vendor driver, rather than in bits. Test the calculations agains a spreadsheet and confirmed by debug prints to be reasonable. - Also verified the register values with relative confidence to register dumps from the Samsung GT-I8190 boot loader graphics. We are not identical but not off by far either. - Error out if the current mode and refresh frequency doesn't work out. (In the future we may simply want to scale down the vrefresh.) - Handle negative result in front/back/sync packages and fall back to zero like in the vendor driver. - Put in lots of clarifying comments and references to the documentation where the code is hard to understand. - Set the DSI_VID_VCA_SETTING2 field DSI_VID_VCA_SETTING2_MAX_LINE_LIMIT to blkline_pck - 6 as in the vendor driver and mask the field properly. - Set the DSI_VID_VCA_SETTING1 field DSI_VID_VCA_SETTING1_MAX_BURST_LIMIT to blkeol_pck - 6 to blkeol_duration - 6 as in the vendor driver.

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).

2019-12-16drm/modes: parse_cmdline: Allow specifying stand-alone optionsHans de Goede
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.

2019-12-16drm/modes: parse_cmdline: Set bpp/refresh_specified after successful parsingHans de Goede
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.

2019-12-16drm/modes: parse_cmdline: Accept extras directly after mode combined with ↵Hans de Goede
options 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.

2019-12-16drm/modes: parse_cmdline: Stop parsing extras after bpp / refresh at ', 'Hans de Goede
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).

2019-12-16drm/modes: parse_cmdline: Fix possible reference past end of stringHans de Goede
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.

2019-12-16drm/rockchip: add ability to handle external dphys in mipi-dsiHeiko Stuebner
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: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-5-heiko@sntech.de
