2011-02-25ENGR00139755 mxc edid: work around no support interlaced modeJason Chen
Remove interlaced mode from fb modelist before it can be supported. Should revert this patch after interlaced mode support on normal display port. Signed-off-by: Jason Chen <b02280@freescale.com>
2011-02-25fbdev: Fix fb_find_nearest_mode refresh comparisonAndrew Kephart
Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved. Signed-off-by: Andrew Kephart <andrew.kephart@alereon.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org> (cherry picked from commit e504b84805c574cf18d705c610c9e4a8f6e61017)

2011-02-21ENGR00139192 - EPDC fb: Refine merging and workaround missed collisionDanny Nold
Added code to detect the potential for a "missed collision", where an update would cause a collision with an update sitting on the collision list, but does not do so with currently active updates. For this case, we conservatively treat the update as if it has generated a collision. Refined merging algorithm by blocking the merge process upon detecting certain conditions where no further merges should be done. Also added check for a special case where update regions are identical. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-02-12ENGR00138642-2 usb-device: fix spin lock recursion problemPeter Chen
Some functions at setup_received_irq will cause spin lock recursion problem, unlock spin locks before calling these functions, and re-lock spin locks after executing them. Signed-off-by: Peter Chen <peter.chen@freescale.com>
2011-02-11ENGR00139076 - EPDC fb: Pan display may drop key updatesDanny Nold
Instead of dropping updates with a different panning offset than the current framebuffer panning offset, we just process those updates using the current framebuffer panning offset. This ensures that all requested update regions are processed from the latest buffer. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-08ENGR00138820 - EPDC fb: PxP mutex handling may cause race conditionDanny Nold
PxP mutex was being released and retaken while EPDC power turned on. This provides opportunity for a race condition where another thread attempts to being a PxP operation and corrupts the PxP data structures of the EPDC. PxP mutex now held through the EPDC powerup sequence. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-08ENGR00138821 - EPDC fb: Panning may cause missed collisionDanny Nold
- When update is processed, we check against latest panning offset and drop the update if they don't match. This ensures that we always update using the most current buffer location. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-03ENGR00138652 - EPDC fb: Out-of-memory due to alloc/free temp buffersDanny Nold
Statically allocate buffers for each update object, rather than dynamically allocating/freeing buffers per use. These buffers are used when PxP limitations require update content first be copied into a temporary buffer. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-03ENGR00138742 - EPDC fb: Driver may run out of markers after a whileDanny Nold
Markers now cleared once the associated LUT completes. This ensures that markers will always be cleared. The marker does not have to be waited on to be cleared. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-03ENGR00138651 - EPDC fb: Rotation updates clipped incorrectlyDanny Nold
- Corrected the computation of PxP input/output buffer address offsets - Corrected the computation of EPDC input buffer address offset - Expanded cases requiring SW of update contents pre-PxP processing, now covering: - Case where input address offset is not 32-bit aligned and auto-waveform mode selected - Case where input address is not 32-bit aligned and total pixels added per-line to PxP processing task is 8 or more. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-02-03ENGR00138513 - EPDC fb: Auto-waveform selecting wrong waveform modeDanny Nold
- Software workaround for PxP alignment/histogram limitation implemented For updates using auto-waveform selection and using update region dimensions that are not 8x8 multiples, the update region is copied into a temporary buffer and the margins filled with 0s. This buffer becomes the input to the PxP. - PxP/EPDC buffer offsets adjusted to properly handle all rotation cases. Signed-off-by: Danny Nold <dannynold@freescale.com>
