2010-10-27ENGR00132894 usb: clk_get should not be called at IRQ contextPeter Chen
The old implementation will clk_get/clk_put for each clk on/off operation. As some clk on/off operation would be IRQ context. So, it will ocurr the error like "schedule at atomic context". The new implementation will only call clk_get at usb initialization, and clk_put at usb de-initialization. The driver's clock on/off will only call clk_enable/clk_disable.

2010-10-21ENGR00132874 Mx50: Donot change Vcc votlage in LPAPM modeRanjani Vaidyanathan
Vcc voltage needs to be increased before increasing the frequency when exiting from LPAPM mode. Some drivers are initiating the frequency/voltage change request (via clk_enable/clk_disable) in an ISR or tasklet context. Since the regulator API code uses SPI that can sleep during its transactions, the system will crash when sleep is called in an ISR/tasklet context. Hence the current solution is to remove the voltage change code. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>

2010-10-19ENGR00132153 sgtl5000: do not enforce symmetry if rate is unknownAlan Tull
If a playback and a record stream are started together, the alsa userspace may not not do the necessary ioctl calls for the audio driver stack to know the sample rate and sample size of the first stream before starting the second stream, i.e.: arecord -D plughw:0 -d 10 -f S16_LE -r 44100 -c 2 -traw | aplay -D plughw:0 -f S16_LE -r 44100 -c 2 -traw Normally we want to the driver to make sure that the second stream does not request a different playback rate/bit size from the first stream. But at that point, the driver thinks that the sample rate and sample size are 0. So in that case do not enforce constraints. This still allows for usecases where play is started first and then record is started after a delay while playback continues. Signed-off-by: Alan Tull <alan.tull@freescale.com>
2010-10-19ENGR00132649 SAHARA test causes ext3 file system crashAnish Trivedi
During kernel upgrade, replaced deprecated functions: dmac_clean_range() with clean_dcache_area() and, dmac_inv_range() with invalidate_kernel_vmap_range(), but that results in some test case failures when file system is on the SD card instead of NFS. Quite possibly the cache coherency problems were not showing up during NFS testing. Corrected this by using the proper replacements: dmac_clean_range() replaced by dmac_map_area() and, dmac_inv_range() replaced by dmac_unmap_area(). This fixes the cache coherency issues and all tests pass with file system on SD card as well mounted over NFS. Signed-off-by: Anish Trivedi <anish@freescale.com>
2010-10-19ENGR00132761 MX51: correct the debug early uart's clockXinyu Chen

During data transfer between pc and imx board, if unplug the cable, the udc will enter low power mode and the gadget class driver is disconnected from the udc driver with the ep->desc cleared, this is done in udc irq handler which may interrupte the current udc queue operation, so when queue operation can continue it's work, the ep->desc may be NULL which will cause the NULL pointer exception in kernel.
