2011-01-27ENGR00138121 Fix system hangs when arecord/aplay continuouslyrel_imx_2.6.35_11.01.00Zeng Zhaoming
Sdma iapi start loading sdma script by write HSTART register as memory. When instruction reorder and IRQ delay may let the next synchronize operation wait forever. We change it by using writel() to access sdma registers, and introduce timeout to show this error. HSTART and STOP_STAT contain bits that are reset by hardware. So if we read-modify-write, we are in danger of setting a bit after SDMA has cleared it. The spec calls these registers "write-ones" register. So the ARM can write a 1 to any bit, but does not need to worry about clearing any bits that were previously set. SDMA hardware keeps track of all bits that were set.

2011-01-27ENGR00138540 mx51: set low bus flag after entering low bus modeLily Zhang
If enabling DVFS core and enter suspend state, FEC resume was failed due to wrong clock. This is because enter_lpapm_mode_mx51 function doesn't set low_bus_freq_mode flag after commit 30f6fc381. It causes the system is in wrong low bus mode. Signed-off-by: Lily Zhang <r58066@freescale.com>

2011-01-25ENGR00138516: MX5X: Initialize CPU working point correctly for DVFS-CORERanjani Vaidyanathan
CPU working point needs to be initialized based on the current CPU frequency in start_dvfs() and should correspond with the correct entry in the cpu_wp_auto table. If its not initialized correctly, DVFS-CORE will fail when PLL-relock results in a frequency that is not the same as set in the cpu_wp_auto table. So fix it by finding the entry that closely matches the CPU frequency. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>
2011-01-25ENGR00138333 MX5x In security drivers use IS_ERR to check for clk pointer errorAnish Trivedi

2011-01-16ENGR00137958-2 Add mx53 smd&loco suspend via i2c commandZhou Jingyu
Add mx53 smd&loco suspend via i2c command Only a maximu 30ms delay before da9053 enter suspend, thus the command is sent out at the latest stage of system suspend operation when all other drivers already suspended and irq disabled. A standalone polling-mode i2c interface is therefor deployed for the suspend command operations. In current solution, mx53 fails to resume from 1GHZ working poing when reduce VDD &VCC to stop mode level. Thus a workaround is added to set mx53 working point to 400MHZ before suspend and restore to previous working point after it resume back. Signed-off-by: Zhou Jingyu <Jingyu.Zhou@freescale.com>
