2011-09-20Revert "HACK: OMAP: DSS2: clk hack for OMAP2/3"Tomi Valkeinen1-4/+1
This reverts commit 9ede365aa6f74428a1f69c21ca1cf21213167576. The hack is no longer needed, as the HWMOD data has been fixed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-08-01HACK: OMAP: DSS2: clk hack for OMAP2/3Tomi Valkeinen1-1/+4
The HWMOD data for OMAP2 and 3 are currently not up to date regarding DSS (OMAP4 HWMOD data is fine). This patch makes the DSS driver to get the opt clocks needed for OMAP2/3 with the old clock names, thus allowing DSS driver to use runtime PM. The HWMOD databases should be fixes ASAP, and this patch can be reverted after that. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-07-25OMAP: DSS2: Use PM runtime & HWMOD supportTomi Valkeinen1-23/+142
Use PM runtime and HWMOD support to handle enabling and disabling of DSS modules. Each DSS module will have get and put functions which can be used to enable and disable that module. The functions use pm_runtime and hwmod opt-clocks to enable the hardware. Acked-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-07-01OMAP: DSS2: Add FEAT_VENC_REQUIRES_TV_DAC_CLKTomi Valkeinen1-6/+10
OMAP3430 requires an 96MHz clock to VENC's DAC, but no other OMAP needs it. Add a new feature, FEAT_VENC_REQUIRES_TV_DAC_CLK, which tells if the clock is needed on this platform, and use that feature in venc.c to decide if the clock needs enabling.

2011-07-01OMAP: DSS2: remove update_mode from omapdssTomi Valkeinen1-17/+0
Remove the whole update_mode stuff from omapdss driver. If automatic update for manual update displays is needed, it's better implemented in higher layers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-05-11OMAP: DSS2: VENC: Add missing start/stop_device callsTomi Valkeinen1-0/+12
VENC code was missing omap_dss_start/stop_device calls. This didn't cause any problems as VENC could not be compiled as a module, but nevertheless it's better to add the calls. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-05-11OMAP: DSS2: VENC: Remove sleeps at venc enable/disableTomi Valkeinen1-6/+0
VENC code had 50ms sleep after enabling the output and 100ms sleep after disabling the output. I don't see any reason for these sleeps. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-05-11OMAP: DSS2: VENC: make 20ms venc bug-fix sleep optionalTomi Valkeinen1-0/+3
There's a 20ms sleep after VENC reset. It's unknown what bug this circumvents and on what platforms. Add a Kconfig option to disable the sleep. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-05-11OMAP: DSS2: Move display.h to include/video/Tomi Valkeinen1-1/+1
arch/arm/plat-omap/include/plat/display.h is an include for the OMAP DSS driver. A more logical place for it is in include/video. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-14HACK: OMAP: DSS2: VENC: disable VENC on OMAP4 to prevent crashTomi Valkeinen1-0/+6
Something seems to be wrong with OMAP4 & VENC, and register access fails in omap_venchw_probe(). This patch skips venc driver registration on OMAP4, thus circumventing the problem for now. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-11OMAP: DSS2: Delay regulator_get() callsTomi Valkeinen1-18/+13
DSS submodules DPI/SDI/DSI/VENC require a regulator to function. However, if the board doesn't use, say, SDI, the board shouldn't need to configure vdds_sdi regulator required by the SDI module. Currently the regulators are acquired when the DSS driver is loaded. This means that if the kernel is configured with SDI, vdds_sdi regulator is needed for all boards. This patch changes the DSS driver to acquire the regulators only when a display of particular type is initialized. For example, vdds_sdi is acquired when sdi_init_display() is called.

2011-03-11OMAP2PLUS: DSS2: Generalize naming of PRCM related clock enums in DSS driverArchit Taneja1-4/+4
enum dss_clock structure is replaced with generic names that could be used across OMAP2420, 2430, 3xxx, 44xx platforms. Signed-off-by: Sumit Semwal <sumit.semwal@ti.com> Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-11OMAP2,3: DSS2: Use platform device to get baseaddrSenthilvadivu Guruswamy1-3/+8
DSS, DISPC, DSI, RFBI, VENC baseaddr can be obtained from platform_get_resource(). This API in turn picks the right silicon baseaddr from the hwmod database. So hardcoding of base addr could be removed.

2011-03-11OMAP2, 3: DSS2: VENC: create platform_driver, move init, exit to driverSenthilvadivu Guruswamy1-40/+76
Hwmod adaptation design requires each of the DSS HW IP to be a platform driver. So a platform_driver for VENC is created and init exit methods are moved from core.c to its driver probe,remove. pdev member has to be maintained by its own drivers. Also, venc_vdda_dac reading is moved to venc.c. VENC platform driver is registered from inside omap_dss_probe, in the order desired.

2010-02-12OMAP: DSS2: enable VDDS_DSI when using DPITomi Valkeinen1-3/+1
It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly. This has not been confirmed from TI, but looking at figure 15-1 "Display subsystem highlight" from the TRM, some data pins come near the DSI and SDI blocks. This is not very hard evidence, but the fact remains that with the power on, pixels are ok, and with the power off, pixels are not ok. It may also be that VDDS_SDI is needed to power some pins, but as normally both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't been shown. It seems that a single driver can only get a regulator once. This patch solves it by getting all the required regulators in one place, and from which the submodules then get the regulators they need.
