ENGR00176159 video: ipuv3-fb: change to timeout semaphore to wait on irq.

2012-03-06T06:58:07+00:00

change to timeout semaphore to wait on irq.

use no timeout semaphore have below issues:
1. since fbmem.c will hold the console_lock() before call PAN_DISPLAY ioictl,
 if have wrong happens on IPU, IRQ not come, any log printk will not ouput,
 it will become like a system hang, and developer don't know what's wrong.

2. semaphore don't have timeout, here we can't know irq not come,
  so hang it infintly.
3. semaphore lock and unlock in different context is a dangous operation.

To fix these issue, use timedout version to wait on irq.
But for better coding stly to align Kernel Coding Style Doc,
better use complete to wait on irq, use semaphre little ugly.

ENGR00175261 - EPDC fb: Remove warning messages from EPDC init

2012-03-01T16:42:35+00:00

- Remove screen update from probe function.  This update is redundant.
The update in mxc_epdc_fb_fw_handler() will update and show the tux
logo if FB console is added, so this achieves the same effect as the
update invocation that was removed.
- Remove dmaengine_get(), because SDMA driver returns a failure when
cycling through DMA channels.  Since it is not essential to register
with this call, it has been removed.  dmaengine_put() also removed.
- Added hw_inialization variable to track whether HW is in process
of being initialized.  In which case, we do not print an error
message when an update is received.
