2012-12-12ENGR00232530 Refine VPU suspend/resume according to open_countHongzhang Yang
1. Refine VPU suspend/resume according to open_count to completely fix bug: ENGR00230203 [Android_MX6DL_SD] Gallery: System hang after resume from suspend during video playback. 20% open_count == 0 case can be simplified because VPU is released (all instances are freed), so - clock is already off - context is no longer needed - power is already off on MX6 VPU reset is removed from resume because power is ensured to be off before entering resume on MX6 by calling regulator API. 2. Fix bug: VPU always busy after suspend/resume Error log (VPU refused to suspend due to VPU busy): pm_op(): platform_pm_suspend+0x0/0x54 returns -11 PM: Device mxc_vpu failed to suspend: error -11 PM: Some devices failed to suspend Root cause: - Suspend happened during vpu_Init(), somewhere after VPU lib started to download FW (when PC == 0), but before run FW. (BIT_BUSY_FLAG=1, BIT_CODE_RUN=1). - In such case, VPU resume downloaded FW and run VPU to idle because suspend was triggered after VPU was opened (active). - vpu_Init run VPU again with BIT_BUSY_FLAG=1. So VPU was trapped in idle loop but BIT_BUSY_FLAG was never cleared. VPU lib regarded VPU as always busy. Solution (in VPU resume): - run VPU FW only if VPU was opened and PC before suspend is not 0 - restore host register is required - download FW is required, because program memory is lost after power off.

2012-11-28ENGR00234401: CAAM: Fix incorrect invalidate call for output ringSteve Cornelius
The job ring driver exhibited a hang condition in the top of caam_jr_dequeue() where a BUG_ON statement looks for a condition where the output ring is said to have valid entries by the ring logic, but the ring entries apparently have NULL descriptor pointers. In the initial ARM port of this driver, the cache flush call of the output ring content occured before the output ring read index register read occurred, exposing a condition where the driver sensed valid output entries, yet the entries written by the ring hardware were not invalidated, and therefore were not visible to the processor, appearing as false NULL entries. This patch relocates the invalidate call to immediately follow the check of the output read index, where it is required.

2012-11-28ENGR00233494 EPDC: Driver only supports 16 LUTsMichael Minnick
This bug was introduced by ENGR00229290 which fixed the problem of greater than 16 LUTs used when 5-bit waveform loaded. The bug is that now the driver is also restricted to using 16 LUTs in 4-bit mode. The fix is to correct the test of the EPDC_FORMAT register used to determine if a 5-bit waveform is loaded. Also removed the while loop in favor of a bitwise OR used to determine if a chosen LUT has yet to be acknowledged by the interrupt handler.

2012-11-16ENGR00233800: CAAM: running sha_speed in cryptodev crashedTerry Lv
The reason is that when switching from SHA1 to SHA256, cryptodev will create a new session. But in this new session, the __ctx in allocated req is not fully initialized. Thus dma_buf in __ctx will be a random value. If the value is 0 or some address in DMA memory, that will be ok, otherwise, it will crashed in dma_unmap_single(). The calling sequence is: ahash_final_ctx=>try_buf_map_to_sec_sg()=>dma_unmap_single() When calling dma_unmap_single(), the parameter buf_dma is invalid in crash case.

2012-11-16ENGR00233780 ASRC: limit output buffer size to avoid kernel dumpChen Liangjun
For ASRC memory to memory transfer, user would send driver input buffer and driver would copy converted output buffer into user's buffer. However, ASRC can't promise the ratio of output buffer size/input buffer size being equal to output sample rate/input sample rate.e.g, for convert from 8k to 48k and 1000 bytes input buffer size, ASRC may pop out 5999 bytes or 6001 bytes. If driver copy all 6001 bytes into user's buffer, kernel dump may happens cause of accessing unexisted buffer. In this patch, if ASRC output buffer size is larger than user's buffer size, discard exact part. Signed-off-by: Chen Liangjun <b36089@freescale.com>

2012-11-15ENGR00233577 ASRC: add spinlock to protect ASRC pair resourceChen Liangjun
when quit from ASRC driver with CTRL + C, driver close() would free output buffer and close clock. However, it is possible that the buffer is accessed by work task(work task is trigger by interrupt and it would not be stopped by CTRL + C). So ASRC driver should promise that its pair resource(buffer, SDMA channel, and clock) would not be accessed after it is released. In this patch, add protect for pair resource.

2012-11-08ENGR00232660 EPDC: Wrong panel loaded at bootMichael Minnick
The wrong EPDC panel can be loaded at boot time if the machine board file has multiple panel entries with the same video mode parameter values. To reproduce, select a particular panel with u-boot kernel command line parameters, for example: video=mxcepdcfb:XYZZY Add panel XYZZY to arch/arm/mach-mx6/board-mx6sl_evk.c after an existing entry. Use the same video mode parameter settings as the existing entry. On boot, the existing panel will be loaded instead of the XYZZY panel because it comes earlier in the list and happens to have the same video mode parameter values. Solution: If the video mode parameter settings specified in the call to msc_epdc_fb_set_par() match those of the panel already loaded by mxc_epdc_fb_probe(), don't execute a search for a new matching panel.

Since sdhci_pltfm_data is stored in platform_device_id, but in sdhci_pltfm_remove, it tried to get sdhci_pltfm_data directly from pdev->dev.platform_data. It will result that it could not get the correct sdhci_pltfm_data, so that platform exit will not be called on sdhci module's removal.

There is a USB hang issue when do system suspend/resume test with a USB device plug in. The issue is caused by USB host driver accessing register when clock is off. Currently set HCD_FLAG_HW_ACCESSIBLE bit before open clock in ehci_fsl_bus_resume, it cause accessing register without clock. So we should change the code call order to avoid driver access register without clock. - Set HCD_FLAG_HW_ACCESSIBLE software flag after HW clock turn on - remove some unnecessary code in ehci_fsl_pre_irq Signed-off-by: make shi <b15407@freescale.com>

2012-11-06ENGR00231773-8 ASRC: prevent user app from processing input/output processingChen Liangjun
To finish a buffer convert in ASRC, user should 1. prepare input buffer, 2. prepare output buffer 3. wait for output buffer's completion 4.wait for input buffer's comletion. The flow make user application ugly. In this patch, pack steps above to 1 stop: ASRC_CONVERT. Signed-off-by: Chen Liangjun <b36089@freescale.com>
2012-11-06ENGR00231773-6 SDMA: add event pending trigger interfaceChen Liangjun
When SDMA is use for periphal data transfer, dma request is trigger by FIFO level. If the SDMA is started after the start of periphal, SDMA would miss the first pulse and be not able to trigger itself. In this patch, add interface to trigger a dma request manully.

2012-11-06ENGR00231773-5 ASRC: use poll mode to receive last period of ASRC dataChen Liangjun
ASRC driver use DMA to transfer data from ASRC output FIFO to memory. However, DMA way require the data number in ASRC output FIFO being larger than watermark level. Thus a dma request can trigger a DMA burst. For the last period of output data, its number is possiblely less than output FIFO watermark level. In this case, the output DMA would pending for the last period of output data until timeout. In this patch: 1 divide expected output data length into 2 parts: DMA part and poll part. Using DMA to get the DMA part data and poll mode to get the poll part. 2 to prevent user from processing these 2 parts above, kernel buffers would be untouchable. User application only need send its data buffer address to driver instead of query the kernel buffer. Signed-off-by: Chen Liangjun <b36089@freescale.com>
2012-11-06ENGR00231773-4 ASRC: use scatter list and stall bit for asrc convertChen Liangjun
In the origin code, ASRC driver use cyclic way to process DMA task transfering data to/from ASRC input/output FIFO. In this case, it is necessary that user application should promise that the input buffer flow is continuous. If not, there would be 0 data be inserted into data flow. The output data would be noisy. In this patch, 1 use scatter list instead of cyclic SDMA: with scatter list, SDMA would stop when the applied scatter list nents are finished. 2 set stall bit for ASRC "memory->ASRC->memory" convert to stop ASRC convert when input data is not send into ASRC input FIFO in time.

2012-11-06ENGR00231773-3 ASRC: use kzalloc to allocate buffer to support scatterlistChen Liangjun
For ASRC's "memory -> ASRC -> memory" using, new driver would support model below: user input one buffer into ASRC and an corresponding output buffer would be poped out. There is no timing requirement between this input buffer and next input buffer. Thus driver would not use the cyclic way to config SDMA and scatterlist is used. buffer allocated by dma_alloc_coherent() can't support scatterlist well. In this patch, use kzalloc to allocate buffer to support scatterlist. Signed-off-by: Chen Liangjun <b36089@freescale.com>
2012-11-06ENGR00231773-2 ASRC: add work struct for asrc output data receiveChen Liangjun
SDMA driver can't promise receive all output data generated. Cause when the data in output FIFO is less than ASRC output FIFO watermark, there would be no DMA request generated and thus no SDMA transfer would happens. In this patch, add work struct to support ASRC driver receive last part of data in OUTPUT FIFO in polling way. Signed-off-by: Chen Liangjun <b36089@freescale.com>
2012-11-06ENGR00231773-1 ASRC: remove queue operation in ASRC driverChen Liangjun
According to ASRC memory->ASRC->memory requirement, driver should satisfy the feature below: user application would passed into one buffer and waiting until the output buffer is generated. In this case, only one buffer is on processing and it is no necessary to use the queue to do the convert. What is worse, queue operation would make the ASRC driver hard to understand and maintain. In this patch, remove the queue operation in ASRC driver. Signed-off-by: Chen Liangjun <b36089@freescale.com>

Bluetooth H4 protocol is very susceptible to data reception timeouts. DMA transfer only happen when ICD or AGTIM interrutps are trigger. ICD only happen when a N idle frames are present on rx line and rx FIFO is empty. Meanwhile Aging timer is trigger when data in FIFO was been sitting for a period of 8 frames. This patch enable both in order to dispatch data as fast is possible only when the select uart have enable DMA flag. Signed-off-by: Israel Perez <B37753@freescale.com>
