2012-07-23OMAPDSS: DISPC: Read fifo size of Writeback pipelineArchit Taneja
The Writeback pipeline is a block in OMAP4's Display controller which can take input from a pipeline or an overlay manager and feed it back to memory. Hence, it allows to take benefit of the hardware processing available inside the DISPC like color space conversion, rescaling, compositing to perform memory-to-memory transfer with data processing or capturing a displayed frame. The Writeback pipeline has it's own FIFO like the other pipelines. Since Writeback isn't supported in OMAPDSS yet, we can use it's FIFO for some other pipe which needs it. OMAP4 DISPC has a mechanism to share FIFOs among pipes which makes this possible. Add writeback pipeline as a member of omap_plane struct, add register offsets for it's FIFO_SIZE_STATUS register so that the DISPC driver is aware of it's fifo size. This would be used later to transfer the FIFO to another pipe, and have a larger FIFO during fifomerge.

2012-06-22staging: drm/omap: Provide hpd change frrom irq handlerJassi Brar
Currently the drm polls HPD every 10secs. If an unplug-plug cyles completes within that time, we might miss the re-attach of potentially a different display. Also if the display is plugged in immediately after the poll, 10s are quite long for power management of the link,unaware of any change in connection, to possibly change during edid read, hence giving the "operation stopped when reading edid" like errors. Remedy the situation by making omapdrm provide a way for connector drivers to call drm_helper_hpd_irq_event(). Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
2012-06-22OMAPDSS: HDMI: Discard phy_tx_enabled memberJassi Brar
Explicitly maintaining HDMI phy power state using a flag is prone to race and un-necessary when we have a zero-cost alternative of checking the state before trying to set it. Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
2012-06-22OMAP2: DSS: HDMI: Check for either error not bothJassi Brar
Error is either wrong timings code or bad pixel clock. Otherwise, we risk accepting some invalid timings but with valid pixel_clock. Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
2012-06-22OMAPDSS: HDMI: support non-cea non standard VESA formatsMythri P K
If the timings sent to check does not match any of the standard modes, assume that is a custom timing and set it to VESA mode with 0 as code, As CEA standard would need to send CEA code during the AVI info frame and behaviour is a wrong code is sent is not understood currently on VESA (non- Audio) non-standard timing is supported if the max pixel clock requested is less than the maximum pixel clock supported by OMAP for HDMI.

2012-06-22dss: GLOBAL_BUFFER hackRob Clark
For 2d scanout at higher resolutions we need to increase the gfx pipe dma buffer.. since we aren't using writeback pipe, assign it's buffers to gfx.
2012-06-22OMAPDSS: HDMI: HACK: Set idle mode when playing audio.Ricardo Neri
As per design, the HDMI wrapper needs to be set to no idle when playing audio. This is needed as the audio part in the HDMI wrapper uses the interface clock to work. Hence, if not set to no-idle the interface clock may be cut even when the rest of the HDMI module is still on (as it works with the functional clock). This is a HACK as it should be done automatically by the pm framework. A more elegant solution is shall be implemented. Signed-off-by: Ricardo Neri <ricardo.neri@ti.com>
2012-06-22OMAPDSS: HDMI: OMAP5: Write the most signifcant nibble of CTS correctlyRicardo Neri

2012-06-22OMAPDSS: HDMI: Make pio driver a libraryMythri P K
As pio driver is currently a subsidiary of DSS and thus if PIO is made a module it will result in compiler error if DSS is built as a module so make it is a library and call the init function from HDMI driver as currently HDMI is the only driver which is using it.
