| * | drm/omap: add field for PLL typeTomi Valkeinen2016-05-194-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DSS uses two types of PLLs, type A (DSI & Video) and type B (HDMI). The two types behave slightly differently, but we don't have the type of the PLL available anywhere for the driver. This patch adds an enum for the PLL type and a field in the PLL's HW data to store it. Signed-off-by: Tomi Valkeinen <[email protected]>

| | | | | | | | | | | | | | | | | | | | | The names of the enum dss_clk_source's values are legacy names, only correct for OMAP3 DSS. Rename the names to more generic ones. Signed-off-by: Tomi Valkeinen <[email protected]>
| * | drm/omap: rename dss_get_generic_clk_source_name()Tomi Valkeinen2016-05-194-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | Now that there is no "non-generic" version of the function to get the clock source name, lets rename dss_get_generic_clk_source_name() to dss_get_clk_source_name(). Signed-off-by: Tomi Valkeinen <[email protected]>
| * | drm/omap: remove dss_feat_get_clk_source_name()Tomi Valkeinen2016-05-195-59/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have two functions to return a name for clock sources for debugging purposes: dss_feat_get_clk_source_name() and dss_get_generic_clk_source_name(). The former is supposed to return a DSS IP version specific name for the clock source, and the latter is supposed to return a more generic name. All this seems a bit pointless, so let's remove the former one. Signed-off-by: Tomi Valkeinen <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | At the moment 'enum omap_dss_clk_source' is in omapdss.h, shared by omapdrm and omapfb. We're about to improve the omapdrm clock code, so we need to make a separate copy of the enum for each driver. Signed-off-by: Tomi Valkeinen <[email protected]>
| * | drm/omap: video-pll: add missing data for clkout2 & 3Tomi Valkeinen2016-05-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Video pll hw data is missing bitfield definitions for clkout2 and clkout3. We don't use those clkouts at the moment, so this has not caused any issues. Add the bitfields. Signed-off-by: Tomi Valkeinen <[email protected]>

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

* | drm/omap: Remove regulator API abusePeter Ujfalusi2016-05-313-27/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>
* | OMAPDSS: HDMI5: Change DDC timingsJim Lodes2016-05-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The DDC scl high and low times were set to the minimum values from the i2c specification, but the i2c specification takes into account the rise time and fall time to calculate the frequency. To pass HDMI certification DDC can not exceed 100kHz therefore in a system where the rise times and fall times are negligible the high and low times for scl need to be 10us.

* | drm/omap: fix OMAP4 hdmi_core_powerdown_disable()Tomi Valkeinen2016-05-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hdmi_core_powerdown_disable() is supposed to disable HDMI core's power-down mode. However, the function sets the power-down bit to 0, which means "enable power-down". This hasn't caused any issues as the PD seems to affect only interrupts from HDMI core, and none of those interrupts are used at the moment. CEC functionality requires core interrupts, and the PD mode needs to be fixed. This patch fixes hdmi_core_powerdown_disable() to actually disable the PD mode.

* drm/omap: remove use of omapdss_find_mgr_from_display()Tomi Valkeinen2016-03-031-18/+0
| | | | | | | | | | | | | | | In order to remove uses of 'struct omap_overlay_manager' we need to get rid of using omapdss_find_mgr_from_display() when initializing omapdrm. Instead of using omapdss_find_mgr_from_display() and mgr->id to find the dispc channel used for the given display, we can instead use omapdss_find_output_from_display(), and get the output->dispc_channel from there. We can also remove omapdss_find_mgr_from_display() as it's no longer used. Signed-off-by: Tomi Valkeinen <[email protected]>

* drm/omap, omapfb: move exported dispc function declarations to omapdrm/omapfbTomi Valkeinen2016-03-032-0/+63
| | | | | | | | | | | | | | | | omapdrm and omapfb still share the same include/video/omapdss.h. We need to change that so that we can proceed with omapdrm work. However, it's not trivial to make separate omapfb and omapdrm versions of omapdss.h, as that file is also included in other places like arch code, audio code and omap_vout code. So we'll do it piece by piece. This patch makes private versions of all the dispc function declarations that are in omapdss.h. For omapdrm we create a new file, drivers/gpu/drm/omapdrm/dss/omapdss.h, which will contain headers meant to be visible outside omapdss. Signed-off-by: Tomi Valkeinen <[email protected]>
* drm/omap: move dss_suspend/resume_all to core.cTomi Valkeinen2016-03-033-15/+13

* drm/omap: fix suspend/resume handlingTomi Valkeinen2016-03-033-67/+0
| | | | | | | | | | | | | | | | For legacy reasons omapdss handles system suspend/resume via PM notifier callback, where the driver disables/resumes all the outputs. This doesn't work well with omapdrm. What happens on suspend is that the omapdss disables the displays while omapdrm is still happily continuing its work, possibly waiting for an vsync irq, which will never come if the display output is disabled, leading to timeouts and errors sent to userspace. This patch moves the suspend/resume handling to omapdrm, and the suspend/resume is now done safely inside modeset lock. Signed-off-by: Tomi Valkeinen <[email protected]>
