2011-10-03OMAPDSS: DISPC: zorder support for DSS overlaysArchit Taneja2-0/+96
Add zorder support on OMAP4, this feature allows deciding the visibility order of the overlays based on the zorder value provided as an overlay info parameter or a sysfs attribute of the overlay object. Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER if the caps are not available. Ensure that all overlays that are enabled and connected to the same manager have different zorders. Swapping zorders of 2 enabled overlays currently requires disabling one of the overlays.

2011-10-03OMAPDSS/OMAP_VOUT: Fix incorrect OMAP3-alpha compatibility settingArchit Taneja5-35/+46
On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. On OMAP4, alpha blending is always enabled by default, if the above bits are set, we switch to an OMAP3 compatibility mode where the zorder values in the pipeline attribute registers are ignored and a fixed priority is configured. Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4 alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is expected to check for the ZORDER cap, if an overlay doesn't have this cap, the user is expected to set the parameter partial_alpha_enabled. If the overlay has ZORDER cap, the DSS2 user can assume that alpha blending is already enabled. Don't support OMAP3 compatibility mode for now. Trying to read/write to alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits. Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha blending or not. Replace this with checks for VIDEO1 pipeline.

dispc_mgr_pclk_rate() is used to calculate minimum required functional clock for scaling in calc_fclk() and calc_fclk_five_taps(). This function returns the correct pixel clock for LCD and LCD2 managers, but not for TV manager. Extend this function so that it gets the correct pixel clock for TV manager. This also prevents the crash we get when we try to scale overlays connected to TV manager. The current code leads to a BUG() being executed if we call dispc_mgr_pclk_rate() for the TV manager.

2011-09-30OMAP: DSS2: HDMI: make set_timing sanerTomi Valkeinen2-8/+12
Currently the set_timings code for hdmi is quite strange. The display is disabled in hdmi_omap4_panel.c before setting timings, and enabled in hdmi.c after setting the timings. Furthermore, the timings were not permanent, and disabling and enabling the display would lose them. This patch makes the set_timings handling a bit better.

2011-09-30OMAP: DSS2: HDMI: improve hdmi output enableTomi Valkeinen1-2/+2
Enabling HDMI output often causes sync lost errors, and almost always causes timeout errors being printed from dispc_mgr_enable_digit_out(). The sync lost problem seems to go lessen greatly if we first enable the HDMI output, and only then enable the DISPC output. However, as this is only based on observations, the fix may not be perfect as the problem may lie somewhere else. Nevertheless, HDMI works better with this patch. This will also fix the dispc's dispc_mgr_enable_digit_out(), as the code waits for two VSYNCs after enabling the output. If the HDMI output is disabled (as it was previously), there are no VSYNCs and dispc_mgr_enable_digit_out() will print timeout errors.

regn divider is currently programmed to the registers without change, but when calculating clock frequencies it is used as regn+1. To make this similar to how DSI handles the dividers this patch changes the regn value to be used as such for calculations, but the value programmed to registers is regn-1. This simplifies the clock frequency calculations, makes it similar to DSI, and also allows us to use regn value 0 as undefined.

2011-09-30OMAP: DSS2: DISPC: Fix minimum PCD valueTomi Valkeinen3-4/+14
The current driver had a hardcoded minimum value of 2 for pixel clock divisor (PCD). This doesn't seem to be right. OMAP4 TRM says that PCD can be 1 when not downscaling, and inverted pixel clock (IPC) is off. OMAP3 TRM says the same, but also in the register descriptions that PCD value 1 is invalid. OMAP2 TRM says PCD 2 is the minimum. OMAP2 is still untested, but for both OMAP3 and OMAP4 PCD of 1 seems to work fine. This patch adds a new DSS feature, FEAT_PARAM_DSS_PCD, which is used to find the minimum and maximum PCD. The minimum is set to 2 for OMAP2, and 1 for OMAP3/4.

2011-09-30OMAP4: DSS2: HDMI: Function pointer approach to callMythri P K4-9/+58
HDMI IP fundamentally has replaceable core PHY and PLL blocks. These blocks might vary across OMAP's but the end functionality such as to enable or disable PLL, PHY, function to read EDID would remain the same. Thus to make the current hdmi DSS driver compatible with different OMAP's having different IP blocks( A combination of different core, PHY, PLL blocks), function pointer approach is introduced. With function pointer, relevant IP dependent functions are mapped to the generic functions used by DSS during the initialization based on the OMAP compiled. Thus making hdmi DSS driver IP agnostic.

The current function tries to set 2 different modes(io pad mode and stall mode) based on a parameter omap_parallel_interface_mode which loosely corresponds to the panel interface type. This isn't correct because a) these 2 modes are independent to some extent, b) we are currently configuring gpout0/gpout1 for DSI panels which is unnecessary, c) a DSI Video mode panel won't get configured correctly.
