2016-05-19drm/omap: cleanup DPI clock source handlingTomi Valkeinen1-30/+18
We can clean up the DPI driver's clock source handling by using the dss_clk_source instead of only a dss_pll pointer. This will also make it possible to use additional clock sources, like PLL1_3 or HDMI_PLL, which the code did not support earlier. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2016-05-19drm/omap: add PLL helper funcsTomi Valkeinen2-0/+55
Add two PLL helper functions: dss_pll_find_by_src() which returns the dss_pll for the given dss_clk_source. dss_pll_get_clkout_idx_for_src() which returns the clkout index for the given dss_clk_source. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2016-05-19drm/omap: clean up the LCD clk mux codeTomi Valkeinen3-51/+141
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.

2016-05-19drm/omap: add field for PLL typeTomi Valkeinen4-0/+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 <tomi.valkeinen@ti.com>

2016-05-19drm/omap: rename dss_clk_source enumsTomi Valkeinen5-55/+54

2016-05-19drm/omap: remove dss_feat_get_clk_source_name()Tomi Valkeinen5-59/+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 <tomi.valkeinen@ti.com>

2016-05-19drm/i915: Allow mmio updates on all platforms, v2.Maarten Lankhorst2-93/+7
With intel_pipe_update begin/end we ensure that the mmio updates don't run during vblank interrupt, using the hw counter we can be sure that when current vblank count != vblank count at the time of pipe_update_end the mmio update is complete. This allows us to use mmio updates on all platforms, using the update_plane call. With Chris Wilson's patch to skip waiting for vblanks for legacy_cursor_update this potentially leaves a small race condition, in which update_plane can be called with a freed crtc_state.

After drm_gem_object_lookup() was changed along with all its callers, we have several drivers that have unused variables: drm/armada/armada_crtc.c: In function 'armada_drm_crtc_cursor_set': drm/armada/armada_crtc.c:900:21: error: unused variable 'dev' [-Werror=unused-variable] drm/nouveau/nouveau_gem.c: In function 'validate_init': drm/nouveau/nouveau_gem.c:371:21: error: unused variable 'dev' [-Werror=unused-variable] drm/nouveau/nv50_display.c: In function 'nv50_crtc_cursor_set': drm/nouveau/nv50_display.c:1308:21: error: unused variable 'dev' [-Werror=unused-variable] drm/radeon/radeon_cs.c: In function 'radeon_cs_parser_relocs': drm/radeon/radeon_cs.c:77:21: error: unused variable 'ddev' [-Werror=unused-variable] This fixes all the instances I found with ARM randconfig builds so far.

2016-05-18drm/tegra: Fix crash caused by reference count imbalanceJon Hunter1-4/+11
Commit d2307dea14a4 ("drm/atomic: use connector references (v3)") added reference counting for DRM connectors and this caused a crash when exercising system suspend on Tegra114 Dalmore. The Tegra DSI driver implements a Tegra specific function, tegra_dsi_connector_duplicate_state(), to duplicate the connector state and destroys the state using the generic helper function, drm_atomic_helper_connector_destroy_state(). Following commit d2307dea14a4 ("drm/atomic: use connector references (v3)") there is now an imbalance in the connector reference count because the Tegra function to duplicate state does not take a reference when duplicating the state information. However, the generic helper function to destroy the state information assumes a reference has been taken and during system suspend, when the connector state is destroyed, this leads to a crash because we attempt to put the reference for an object that has already been freed. Fix this by calling __drm_atomic_helper_connector_duplicate_state() from tegra_dsi_connector_duplicate_state() to ensure that we take a reference on a connector if crtc is set. Note that this will also copy the connector state a 2nd time, but this should be harmless. By fixing tegra_dsi_connector_duplicate_state() to take a reference, although a crash was no longer seen, it was then observed that after each system suspend-resume cycle, the reference would be one greater than before the suspend-resume cycle. Following commit d2307dea14a4 ("drm/atomic: use connector references (v3)"), it was found that we also need to put the reference when calling the function tegra_dsi_connector_reset() before freeing the state. Fix this by updating tegra_dsi_connector_reset() to call the function __drm_atomic_helper_connector_destroy_state() in order to put the reference for the connector.
