2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-19drm: Allow drivers to modify plane_state in prepare_fb/cleanup_fbChris Wilson
The drivers have to modify the atomic plane state during the prepare_fb callback so they track allocations, reservations and dependencies for this atomic operation involving this fb.

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

The tv-out crtc has 1024 element gamma table (with 10bit precision) in HW, but current Xorg server does not accept anything else but 256 elements so that is used for all CRTCs.

The workaround sets up a minimal LCD setup with GFX plane and waits for one vertical sync irq before disabling the setup and continuing with the context restore. The physical outputs are gated during the operation.

2016-06-07drm/omapdrm: Add gamma table support to DSS dispcJyri Sarha
Add gamma table support to DSS dispc. DSS driver initializes the default gamma table at component bind time and holds a copy of all gamma tables in its internal data structure. Each call to dispc_mgr_set_gamma() updates the internal table and triggers write to the HW, if it is enabled. The tables are restored to HW in PM resume callback. The drivers internal data structure match the HW tables in size and in number of significant bits per color component. The dispc_mgr_set_gamma() converts the size of any given table for the internal data structure using linear interpolation. Default gamma table is restored if NULL is given in place of gamma lut. dispc_mgr_gamma_size() gives HW gamma table size for the channel and returns 0 if gamma table is not supported by the HW or the DSS driver.

2016-06-06drm/omap: remove unnecessary pitch round-upTomi Valkeinen
omapdrm checks if the pixel stride is divisible by 8. This is meant to ensure that the byte stride is 32, which is required by SGX. The check is not correct, as it checks for pixels, not bytes, and thus needlessly increases the stride for, e.g., NV12. Also, SGX driver is not supported in the mainline, and the TI's SGX driver nowadays does the memory allocation itself and doesn't rely on omapdrm to figure out the correct pitch. So we can just remove the whole roundup. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The omapfb stach is using video/omapfb_dss.h so this change will complete the separation of the two driver implementation. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
2016-06-03drm/omap: Do not include video/omapdss.h directly in driversPeter Ujfalusi
All drivers to include the omapdrm/dss/omapdss.h header file. This header includes the <video/omapdss.h> Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
2016-06-03omapdss: hdmi audio: Make header file independent of video/omapdss.hPeter Ujfalusi
Clean up the header files regarding to hdmi audio so the omap-hdmi-audio.h file will only need to include the platform_data/omapdss.h file.

2016-06-03drm/omap: Remove reference to pdata->default_devicePeter Ujfalusi
The default_device is no longer used, it is a leftower from legacy. The else if (pdata->default_device) is always going to be false. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
2016-06-03drm/omap: connector-analog-tv: Support only Composite type in legacy bootPeter Ujfalusi
In legacy mode (non DT mode) support only composite connector type. The only user for this is rx51, using composite type. Dropping the connector_type selection via pdata will allow cleanups in omapdss (drm vs fbdev). Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>
2016-06-03drm/omap: displays: Do not include video/omap-panel-data.h if not neededPeter Ujfalusi
Some panel/encoder/connector driver includes omap-panel-data.h but they do not need it. Remove the inclusion of video/omap-panel-data.h from these drivers. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com>

2016-05-31drm/omap: include gpio/consumer.h where neededArnd Bergmann
A lot of the display drivers for OMAP use the gpio descriptor functions that are only available in linux/gpio.h if GPIOLIB is enabled and otherwise produce a build error: drivers/gpu/drm/omapdrm/displays/encoder-opa362.c: In function 'opa362_enable': drivers/gpu/drm/omapdrm/displays/encoder-opa362.c:101:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration] drivers/gpu/drm/omapdrm/displays/panel-dpi.c: In function 'panel_dpi_probe_pdata': drivers/gpu/drm/omapdrm/displays/panel-dpi.c:189:23: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration] drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c: In function 'sharp_ls_enable': drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c:120:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration] This replaces the existing linux/gpio.h with linux/gpio/consumer.h where needed. In case of panel-lgphilips-lb035q02.c however, we also have to include linux/gpio.h to get the definition of gpio_is_valid and gpio_set_value_cansleep that are used for the non-DT case.

2016-05-31drm/omap: include linux/seq_file.h where neededArnd Bergmann
The omapdrm driver relies on this header to be included implicitly, but this does not always work, and I get this error in randconfig builds: gpu/drm/omapdrm/dss/hdmi_phy.c: In function 'hdmi_phy_dump': gpu/drm/omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] gpu/drm/omapdrm/dss/hdmi_wp.c: In function 'hdmi_wp_dump': gpu/drm/omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] gpu/drm/omapdrm/dss/hdmi_pll.c: In function 'hdmi_pll_dump': gpu/drm/omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration] This adds the #include statements in all files that have a seq_printf statement.

2016-05-31Revert "drm/omap: no need to select OMAP2_DSS"Peter Ujfalusi
This reverts commit 1c278e5e3718d15475ec08ee2135f37a6b13361c. If DRM_OMAP does not select OMAP2_DSS it is possible to build a kernel with DRM_OMAP only and not selecting OMAP2_DSS. Since omapdrm depends on OMAP2_DSS this will result on broken kernel build. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2016-05-31drm/omap: Remove regulator API abusePeter Ujfalusi
regulator_can_change_voltage() is deprecated and it's use is not necessary as commit: 6a0028b3dd67b regulator: Deprecate regulator_can_change_voltage() describers it clearly. Also, regulator_set_voltage() is misused in the driver, as it is supposed to be used only in cases where the regulator voltage needs to be changed dynamically at runtime. In DSS's case, we always want a fixed voltage, set in the .dts files. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
