* video/omap: fix build dependenciesArnd Bergmann2011-10-031-3/+6
| | | | | | | | | | | Four of the LCD panel drivers depend on the backlight class, so add the dependency in Kconfig. Selecting the BACKLIGHT_CLASS_DEVICE symbol does not generally work since it has other dependencies.

* OMAP4: 4430SDP: Add picodlp support to board fileTomi Valkeinen2011-09-301-0/+52
| | | | | | | | | | | | | | | An on-board projector named picodlp is available for OMAP4430 SDP. Entry for this picodlp as a panel is being added in dss_devices array to the board file. It needs 4 GPIO pins for interfacing with host processor and these are defined and two of them are configured in board file. Two GPIOs power_on and display_select are configured here. picodlp also needs an i2c client over i2c controller-2 at address 0x1b.

* OMAP4: 4430SDP: Add panel support to board fileTomi Valkeinen2011-09-301-2/+128
| | | | | | | | | | | | | | | | | | | | | | | 4430SDP has two Taal DSI panels, connected to DSI 1 and DSI 2 modules. The panels use a common PWM backlight, which will be implemented later when the PWM driver has been improved to support the backlight. Until the PWM driver has been improved, the following hack added to arch/arm/mach-omap2/board-4430sdp.c can be used to set the backlight to max: static int omap_4430sdp_hack_backlight(void) { twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2OFF); twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2ON); twl_i2c_write_u8(TWL6030_MODULE_ID1, 0x30, TWL6030_TOGGLE3); return 0; } late_initcall(omap_4430sdp_hack_backlight); Signed-off-by: Archit Taneja <archit@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAPDSS: remove vaddr from overlay infoTomi Valkeinen2011-09-303-16/+5Star
| | | | | | | | | | | | | | | overlay_info struct, used to configure overlays, currently includes both physical and virtual addresses for the pixels. The vaddr was added to support more exotic configurations where CPU would be used to update a display, but it is not currently used and there has been no interest in the feature. Using CPU to update a screen is also less interesting now that OMAP4 has two LCD outputs. This patch removes the vaddr field, and modifies the users of omapdss accordingly. This makes the use of omapdss a bit simpler, as the user doesn't need to think if it needs to give the vaddr. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAPDSS: Add N800 panel driverTomi Valkeinen2011-09-304-0/+770
| | | | | | | | | | | | | | | | | This is a driver for N800's display, ported from the old omapfb. This is a slightly lighter version of the driver as not all features of the old driver can be ported without big changes to DSS2, and also because some of the HW features used in the old driver are unclear (e.g. the power management part). That said, the new driver works fine for basic use. Architecturally the driver is not as neat as it could be. N800's display HW consists of a display buffer chip and a panel, and ideally they would be represented by separate, independent drivers. This is not currently possible, and this driver contains both buffer chip and panel driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* OMAPDSS: Taal: remove external backlight supportTomi Valkeinen2011-09-302-52/+32Star
| | | | | | | | | | | | | | | | | Taal panel driver supports two kinds of backlight control: 1) using DSI commands sent to the panel to control the backlight, 2) calling function pointers going to the board file to control the backlight. The second option is a bit hacky, and will no longer be needed when the PWM driver supports the backlight features. After that we can use the standard PWM backlight driver. This patch removes the second backlight control mechanism, and adds a boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the board file can use to inform whether the panel driver should use DSI commands to control the backlight.

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

* OMAP: DSS2: HDMI: improve hdmi output enableTomi Valkeinen2011-09-301-2/+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.
