* drm/omap: fix i886 work-aroundTomi Valkeinen2017-08-23
| | | | | | | | | | | | | | | 7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.

| | | | | | | | | | | | The OMAP implementation of the set_min_bus_tput() API is a no-op. There's no point in forwarding the driver calls to the platform code.

* drm/omap: clean up the LCD clk mux codeTomi Valkeinen2016-05-19
| | | | | | | | | | | | | | | | | The code to set the clock muxes for DISPC's LCD clock inputs is very confusing. Especially on DRA7, there's an additional clock muxing that needs to be done, which at the moment is done in dpi.c using dss_ctrl_pll_set_control_mux(). Clean this all up by: - Using dss_clk_source instead of dss_pll_id, as dss_pll_id doesn't specify the clock source quite correctly. - Splitting the dss_select_lcd_clk_source() up into DSS version specific helper functions. - Using dss_ctrl_pll_set_control_mux() from the helper functions, so that dpi.c doesn't have to call it.

* drm/omap: add field for PLL typeTomi Valkeinen2016-05-19
| | | | | | | | | | | 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.

* drm/omap, omapfb: move exported dispc function declarations to omapdrm/omapfbTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | 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 <tomi.valkeinen@ti.com>

* drm/omap: fix suspend/resume handlingTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | 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 <tomi.valkeinen@ti.com>
* drm/omap: move omapdss & displays under omapdrmTomi Valkeinen2015-12-29
Now that omapfb has its own copy of omapdss and display drivers, we can move omapdss and display drivers which omapdrm uses to omapdrm's directory. We also need to change the main drm Makefile so that omapdrm directory is always entered, because omapdss has a file that can't be built as a module.
