This change fixes the random garbage lines when showing NV12 frames decoded by VPU with V4L2 output on XGA@60 display's overlay framebuffer. V4L2 output uses MEM_PP_MEM to do 180 degree rotation.

2011-09-07ENGR00155880 USB device: Fix RNDIS Full Speed hang during initializationAnish Trivedi
When setup irq is received, the status phase of the transfer is primed on ep0 before the data phase. The usb requests are added to the list of transfer descriptors (maintained by driver) in reverse of their expected completion order. Completion order is data followed by status, however the list of tds contains status followed by data. Upon completion of the data request, the irq handler proceeds to check the 1st td in the list -- the status request. In full speed mode, the status phase has not yet completed at this time, so the td's ACTIVE bit is still set. This leads irq handler to ignore the completion interrupt without checking the actual td for the data request that caused the interrupt. In high speed mode, this issue does not bear itself out because the status request also completes by the time the irq handler goes to process the data completion interrupt. The simple fix for this issue is to prime the status request AFTER the data request, so that the list of tds maintained by the driver contains the tds in the order of expected completion.

2011-09-01ENGR00155638 mx53 power: Add DDR float pin operation when system idleWayne Zou
1. Add DDR self-refresh mode and float pin operation when system idle For audio playback use case on android r10.3, it can save 10mA@1.54V about 15mW on DDRIO+ memory power, and 6.6mA@2.5V -16.5mW on VDD_REG It can reduce more memory power consumption if cpu idle time is longer 2. remove the L1/L2 cache operation during suspend for mx53 The L1/L2 cache are powered by VDDA/VDDAL1 and they should be supplied according to iMX53 datasheet, there is also no EMPG on MX53, so it can be removed to improve system performance and power. 3. remap the suspend_iram_base as MT_MEMORY_NONCACHED instead of MT_HIGH_VECTORS If the IRAM page is marked as Cacheable, the ARM cache controller will attempt to flush dirty cache lines to DDR, so it can fill those lines with IRAM instruction code. The problem is that the DDR is in self-refresh mode and HighZ DDR IO PADs during system idle or suspend, so any DDR access causes the ARM MPU subsystem to hang. It needs to cherry-pick two patches(5a4aeb9f6,7c8d972d8) from community. 4. Add DDR self-refresh mode and float pin operation for mx53 ARD board, and mx53 QS/Ripley board This patch can resovle ramdom suspend/resume issue, since the early code didn't consider the TLB missing case during suspend. It needs to save all the M4IF/IO MUX registers firstly to make sure the page table entried into TLB, and then enter DDR self-refresh mode. Signed-off-by: Wayne Zou <b36644@freescale.com>

This patch populates the L1 entries for MT_MEMORY and MT_MEMORY_NONCACHED types so that at boot-up, we can map memories outside system memory at page level granularity Previously the mapping was limiting to section level, which creates unnecessary additional mapping for which physical memory may not present. On the newer ARM with speculation, this is dangerous and can result in untraceable aborts.

2011-08-30Do not call flush_cache_user_range with mmap_sem heldDima Zavin
[ARM] Do not call flush_cache_user_range with mmap_sem held We can't be holding the mmap_sem while calling flush_cache_user_range because the flush can fault. If we fault on a user address, the page fault handler will try to take mmap_sem again. Since both places acquire the read lock, most of the time it succeeds. However, if another thread tries to acquire the write lock on the mmap_sem (e.g. mmap) in between the call to flush_cache_user_range and the fault, the down_read in do_page_fault will deadlock. Also, since we really can't be holding the mmap_sem while calling flush_cache_user_range AND vma is actually unused by the flush itself, get rid of vma as an argument.

2011-08-26ENGR00155292 usb-host: do not clear RS bit when usb bus goes to suspendPeter Chen
The standard EHCI design will clear RS bit after usb bus goes to suspend, but it causes some remote wakeup issues, like remote-wakeup featured device will be reset after resuming. According to usb 2.0 spec, the SOF need to be sent out within 3ms after resume signal ends, or device may consider host disconnects with device. Freescale's USB Controller (Chipidea's core) will ends up resume signal automatically within 21ms after it recevices remote wakeup signal. So, if software does not set RS bit within 21ms after it recevices remote wakeup signal, the problem described above will be occurred. Signed-off-by: Peter Chen <peter.chen@freescale.com>
