2011-07-07ENGR00152681 - EPDC fb: Updates may be shifted right by 1 columnDanny Nold
- Fixed PxP input left coordinate value. Was previously being incorrectly computed such that the value would be incorrect when using 16bpp RGB and an X coordinate that is offset from 4-pixel alignment by 1 (e.g. x=1, x=5). The resulting effect was that updates meeting this criteria would be drawn to the EPD panel shifted to the right by 1 pixel. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-06-23ENGR00151896 - EPDC fb: Fix bug preventing suspend when powerdown disabledDanny Nold
- With FB_POWERDOWN_DISABLE is set as the powerdown delay (disabling the EPDC driver from powering down), the EPDC driver was having problems going into suspend. Any request to blank the EPDC driver would result in a timeout and an error status. And subsequent attempts to send updates to the driver would fail, as the driver's power state was incorrect. This patch prompts the EPDC driver to be disabled when the blanking state is changed to FB_BLANK_POWERDOWN and FB_POWERDOWN_DISABLE is set. Resultingly, the correct driver power state is maintained and suspend/resume works correctly. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-06-21ENGR00151822 - EPDC fb: Prevent endless collision by managing FULL mode updatesDanny Nold
When using SNAPSHOT update scheme, submitting FULL mode updates can easily lead to an endlessly looping sequence of collisions if any updates are active when the new FULL mode update is submitted. Thus, we must first flush any updates out before submitting a new FULL mode update. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-06-22ENGR00151494-1 vpu: remove the code for vpu of mx32/mx37 platformsSammy He
The vpu code in driver for mx32/mx37 is out of date already, and we won't support the platforms, so clean the code for removing it. Signed-off-by: Sammy He <r62914@freescale.com>
2011-06-16ENGR00151639 - EPDC fb: Memory for PxP workaround buffers may be reducedDanny Nold
- This patch changes the way that buffers are allocated and used for the case where PxP alignment limitations are not met (a copy from the update source buffer into a temporary buffer before initiating the PxP processing task is required). Previously, a buffer was allocated on a per-update basis, resulting in a large number of copy buffers. Now, we allocate just one copy buffer that can be reused any time the PxP alignment workaround is required. This is okay because it is assured that only one PxP transaction can be prepared at a time. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-06-09ENGR00142098 - EPDC fb: Fix slow mode transitions when powerdown delay disabledDanny Nold
- When the powerdown delay is set to FB_POWERDOWN_DISABLE, the mxc_epdc_fb_flush_updates() function does not execute correctly, always resulting in a time out while waiting to receive a completion that signals that all updates have completed. This causes long delays when changing the FB mode, since a mode change will always result in a call to mxc_epdc_fb_flush_updates(). Fixed this bug by creating a new mxc_epdc_fb_data variable to track whether all active updates have completed. mxc_epdc_fb_flush_updates() now keys off of this variable to determine whether to wait for all active updates to complete. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-06-01ENGR00144358 - EPDC fb: Fix race condition in how EPDC status is captured in ISTDanny Nold
- Capture EPDC status registers up front in IST, rather than when-needed during IST, to prevent potential race conditions where the status changes mid-IST. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-06-01ENGR00144136 - EPDC fb: Add TCE underrun workaround timeoutDanny Nold
- When synching update submission to EPDC end of frame (when tce_prevent is defined), we should wait using wait_for_completion_timeout to prevent hang/deadlock in case we don't receive completion. - Added call in IST to disable end of frame interrupt upon receiving the interrupt.

2011-05-31ENGR00144306-1 VPU: remove VPU IRAM config and add iram info to plat data.Sammy He
One kernel image is requested, however, we need to enable iram for performance improvement on mx53, and disable it on mx51 due to known issue. So use platform data to pass vpu iram disable/enable flag. And considering requested iram size also can be different per requirement, iram size is also set in platform data.

2011-05-24ENGR00142551-3 MXC V4L2:Change IPU interface for triple bufferLiu Ying
This patch changes IPU interface for MXC V4L2 to align with IPUv3 triple buffer support. When V4L2 is used, we'll change to use double buffer for display channel via internal framebuffer interface.

2011-05-24ENGR00142551-2 IPUv3 FB:Support HW triple bufferLiu Ying
This patch supports HW triple buffer for IPUv3 framebuffer. 1) Remove buf ready check in EOF irq handler, as we think the swap logic will not fail for HW triple buffer case. 2) When V4L2 output/overlay are used, switch to double buffer mode. 3) Changes IPU interface for IPUv1 framebuffer to pass building.
