2010-08-05OMAP: DSS2: Remove extra return statementArchit Taneja1-1/+0
Remove extra return statement in omapdss_default_get_recommended_bpp from overlay.c Signed-off-by: Archit Taneja <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: adjust YUV overlay width to be evenTomi Valkeinen1-0/+15
An overlay in YUV mode has to have an even input width, because data for each pixel is divided between two adjacent pixels. The algorithm handling manual update overlay adjusting may adjust the overlay width to be odd. This patch adds a check for that situation, and makes the width even. The width is increased by one if it is possible (the unadjusted input width is larger than the width), and decreased by one if increasing is not possible.

2010-08-05OMAP: DSS2: OMAPFB: Fix sysfs mirror input checkJani Nikula1-1/+1
Using bool silently converted input to 0 or 1, making the range check useless. Use unsigned long instead, and convert to bool later. Found by Coverity. Signed-off-by: Jani Nikula <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>

2010-08-05OMAP: DSS2: DSI: detect unsupported update requestsTomi Valkeinen1-0/+6
OMAP DSS HW cannot send updates with odd widths. Normally the widths are made even while preparing the update. This patch adds a BUG_ON() to check if the update width is even. This is to detect broken updates cleanly, as otherwise the OMAP DSS HW will just halt, leading to obscure error situations. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: increase FIFO low thresholdTomi Valkeinen1-1/+1
The current FIFO low threshold was too low, and caused the FIFO to run empty when core domain went to INA state between FIFO fills. This patch increases the low threshold to keep that from happening. The threshold values depend quite much on the HW and the use cases, so this should actually be somehow configurable from board files, perhaps. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: Add error IRQ mask for DSI complexIOTomi Valkeinen1-7/+16
The code presumed that all ComplexIO interrupts are errors. This is not the case. This patch adds proper error mask for CIO interrupt handling. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: Remove BTA after set_max_rx_packet_sizeTomi Valkeinen1-9/+1
SMRPS function always sent BTA after sending the SMRPS packet. This is not needed, and also caused some (buggy) panels to bug. This patch removes the BTA. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: change manual update scaling setupTomi Valkeinen6-35/+50
Currently the update area on manual update displays is automatically enlargened to fully cover scaled overlays. This patch makes that optional, allowing the panel driver to choose if it's used or not. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: use BTA to end the frame transferTomi Valkeinen2-63/+58
Previously a work was started on FRAMEDONE interrupt, and this work either sent a BTA synchronously or looped until TE_SIZE was zero, to wait for the end of the transfer. This patch changes a BTA to be sent asynchronously from FRAMEDONE interrupt, and when a BTA interrupt is received, the transfer is finished. This way we do the whole process asynchronously, and also inside interrupt context. This will give us much better latency to handle the end of the frame than with the previous work based solution. Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: change dsi_vc_config_l4/vp()Tomi Valkeinen1-6/+16
Change dsi_vc_config_l4/vp() to loop for the VC_BUSY flag to change, and return an error if it fails. Busy looping is bad, but there's no interrupt that can be used for all the cases where VC can be busy. So the caller should first try to make sure that the VC is not busy, if possible, and then call dsi_vc_config_l4/vp(). Most notable case when the caller cannot be sure if the VC is busy is after frame has been sent. Usually DSI buffers have been emptied until we need to reconfig the VC, but in some rare cases the VC can still be busy, and this patch will handle that case.

2010-08-05OMAP: DSS2: DSI: Disable interface when disabling the displayVille Syrjälä1-0/+7
Once the DSI PLL is separated from the DSI display a full DSI reset will not be performed every time the display is enabled so the interface and VCs must be disabled when disabling the display. If the VCs are not disabled some register accesses will abort. Signed-off-by: Ville Syrjälä <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]>
2010-08-05OMAP: DSS2: DSI: Wait for DSI PLL clocks to be active before selecting themTomi Valkeinen3-0/+26
The TRM tells us to wait for the DSI PLL derived clocks to become active before selecting them for use. I didn't actually have any issues which this would fix but according to the TRM it seems to be the right thing to do.

Separate USB code into a file separate from asic/asic_devices. Separating the USB code from everything else in asic/asic_devices.c goes a long way toward reducing the use of that file as a dumping ground for everything that didn't seem to fit anywhere else.

2010-08-05MIPS: Octeon: Allow more than 3.75GB of memory with PCIeDavid Daney4-14/+87
We reserve the 3.75GB - 4GB region of PCIe address space for device to device transfers, making the corresponding physical memory under direct mapping unavailable for DMA. To allow for PCIe DMA to all physical memory we map this chunk of physical memory with BAR1. Because of the resulting discontinuity in the mapping function, we remove a page of memory at each end of the range so multi-page DMA buffers can never be allocated that span the range.

2010-08-05MIPS: Clean up notify_die() usage.David Daney1-10/+15
The sixth argument of notify_die() is a signal number, the fifth is a trap number. Instead of passing a signal number in a randomly selected argument, pass it in the sixth. Extract the exception code from regs and pass that as the trap number. Get rid of redundant cast, and remove some gratuitous spaces. Nobody actually does anything with the signal number or trap number, but we might as well populate them with sensible values.
