| * drm/sun4i: dsi: Handle bus clock via regmap_mmio_attach_clkJagan Teki2019-12-261-8/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | regmap has special API to enable the controller bus clock while initializing register space, and current driver is using devm_regmap_init_mmio_clk which require to specify bus clk_id argument as "bus" But, the usage of clocks are varies between different Allwinner DSI controllers. Clocking in A33 would need bus and mod clocks where as A64 would need only bus clock. Since A64 support only single bus clock, it is optional to specify the clock-names on the controller device tree node. So using NULL on clk_id would get the attached clock. To support clk_id as "bus" and "NULL" during clock enablement between controllers, this patch add generic code to handle the bus clock using regmap_mmio_attach_clk with associated regmap APIs.

| * udmabuf: fix dma-buf cpu accessGurchetan Singh2019-12-181-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * drm/modes: parse_cmdline: Add support for specifying panel_orientation (v2)Hans de Goede2019-12-163-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
