Merge series from Robert Hancock <robert.hancock@calian.com>:

There are drivers in mainline for the Xilinx Audio Formatter and Xilinx
I2S IP cores. However, because of a few issues, these were only really
usable with Xilinx's xlnx_pl_snd_card top-level driver, which is not in
mainline (and not suitable for mainline).

The fixes in this patchset, for the simple-card layer as well as the
Xilinx drivers, now allow these drivers to be properly used with
simple-card without any out-of-tree support code.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

After the first firmware boot, the firmware is capable of
saving/restoring its context to/from IMR (Isolated Memory Region, set
aside by BIOS on startup). This capability improves the resume speed.

Due to an unexplained issue on Up2 boards, this capability is disabled
on ApolloLake.

For backwards compatibility, the regular boot flow is used with older
firmware. For added peace of mind, a kernel module parameter is
provided to force the regular boot flow - this shouldn't be necessary
since we've been testing these patches for 6+ months.

First patch reduces number of prints we get from failure.
Second allos TLV controls to be either read or write which should be

Last one cleanups after refactoring of memory handling.

Add a new system-clock-fixed flag, which can be used to specify that the
driver cannot or should not allow the clock frequency of the mapped clock
to be modified. This behavior is also implied if the system-clock-frequency
parameter is set explicitly - the flag is meant for cases where a clock is
mapped to the DAI but which is, or should be treated as, fixed.

When mclk-fs is also specified, this causes a PCM constraint to be added
which enforces that only the corresponding valid sample rate can be used.

If an mclk-fs value was provided in the device tree configuration, the
calculated MCLK was fed into the downstream codec DAI and CPU DAI,
however set_sysclk was not being called on the platform device. Some
platform devices such as the Xilinx Audio Formatter need to know the MCLK
as well.

Call snd_soc_component_set_sysclk on each component in the stream to set
the proper sysclk value in addition to the existing call of
snd_soc_dai_set_sysclk on the codec DAI and CPU DAI. This may end up
resulting in redundant calls if one of the snd_soc_dai_set_sysclk calls
ends up calling snd_soc_component_set_sysclk itself, but that isn't
expected to cause any significant harm.

This driver previously only handled the set_clkdiv divider callback when
setting the SCLK Out Divider field in the I2S Timing Control register.
However, when using the simple-audio-card driver, the set_sysclk function
is called but not set_clkdiv. This caused the divider not to be set,
leaving it at an invalid value of 0 and resulting in a very low SCLK
output rate.

Handle set_clkdiv and store the sysclk (MCLK) value for later use in
hw_params to set the SCLK Out Divider such that:
MCLK/SCLK = divider * 2

  ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.
