We may meet the following errors with a SD3.0 DDR50 cards during reboot test.
mmc0: new ultra high speed DDR50 SDHC card at address aaaa
mmcblk0: mmc0:aaaa SU08G 7.40 GiB
mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0xb00
mmcblk0: retrying using single block read
mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0x0
end_request: I/O error, dev mmcblk0, sector 0
.....
Buffer I/O error on device mmcblk0, logical block 0
mmcblk0: unable to read partition table
The root cause is still unknown.
Since there's an errata of Sandisk eMMC card before that it requires delay for CMD6
for eMMC DDR mode to work stable, we also suspect the SD3.0 DDR requires similar delay.
(Still not confirmed by Sandisk)
By adding the delay, the overnight reboot test(run 2000+ times) did not
show the issue anymore. Originally it can easy show the error after about 20 times of
reboot test.
So this patch would be the temporary workaround for Sandisk SD3.0 DDR50 mode
unstable issue.

- the async reset input need ref clock to sync internally,
when the ref clock comes after reset, internal synced reset
time is too short , cannot meet the requirement
so, ssp_en should be asserted at least 4us after ref clock stable.
- align to the community imx pcie driver, add the about
200us delay to make sure that it can allow the pcie clks
stabilize, when pcie clks are enabled on imx6q/dl/solo.

The root cause is CMA memory configured to be too large.
So system memory is exhausted easily, but it can't trigger lowmemorykiller.
The first step to resolve this is change CMA memory to 384M.
Then reduce CMA pages from free pages when allocate non-movable memory.
Low down minfree to half because it is only for non-movable memory.

Patch "ASoC: fsl_sai: Reset FIFOs after disabling TE/RE" may accidentally

Issue reproduce steps:
1. Boot up without HDMI cable plugin
2. Insert the HDMI cable.
3. echo mem > /sys/power/state , enter suspend,
4. resume it,
System can resume from suspend but display is blank.
Error log:
mxc_sdc_fb fb.31: Unable to allocate framebuffer memory
detected fb_set_par error, error code: -12
In mxc hdmi driver, if system bootup without hdmi cable plugin,
driver will create a default modelist.
In fbcon driver, array fb_display[] initialized when system bootup
and save current mode pointer that point to default modelist.
When hdmi cable is plugin the modelist will rebuild according edid
data, but the pointer of video mode in fb_display[] is not updated.
When system resume, fbcon will use the invalidate pointer to
configured framebuffer, framebuffer will crash.
Add function fb_new_modelist() after modelist is rebuild to fix the
issue.

The code incorrectly attempts to set the parent of periph2_clk to periph2_clk2_sel.
Fix this by calling the clk_set_parent() function with the correct parameters.
Also replace all calls to clk_set_parent() and clk_set_rate() with imx_clk_set_parent()
and imx_clk_set_rate() function that prints out error messages in case of failure.

There are a bunch of clk_enable_prepare, clk_set_parent and clk_set_rate
calls in imx6 clock driver's initialization. They are called without
retunr check. If there is something going wrong with the calls, they
will just fail silently.
The patch creates a set of helper functions imx_clk_enable_prepare,
imx_clk_set_parent and imx_clk_set_rate, and use them instead from clock
initialization to check the return and print error message to tell
failures if any.

396MHz in low power idle.
In low power IDLE mode, CPU needs to be sourced from PLL1 instead of PLL2_PFD0
as PLL2 needs to be in bypass mode to achieve 24MHz DDR frequency.
The original code attempts to relock the PLL1 at frequency that is as close
as possible to 396MHz, which results in PLL1 at 648MHz and the ARM freq turns
out to be 324MHz instead of 396MHz. This causes issues with CPUFREQ as 324MHz is
not a frequency listed in the cpufreq table in the device tree.
This patch attempts to fix this mis-match and maintains CPU freq at 396MHz
in low power idle.

The recent addition of the USB audio mixer suspend/resume may lead to
deadlocks when the driver tries to call usb_autopm_get_interface()
recursively, since the function tries to sync with the finish of the
other calls. For avoiding it, introduce a flag indicating the resume
operation and avoids the recursive usb_autopm_get_interface() calls
during the resume.
