In commit bfb9faab8 we added a workaround for some BXT BIOS that fail to
properly initialize the DDI_A_4_LANES bit of the control register (4
lanes is the only valid configuration on BXT since there is no DDI E to
share with). A recent patch added some additional checks on this
register bit before the workaround gets applied; this breaks eDP on BXT
in some settings. Some minor code shuffling is all we need to restore
the workaround.

The only remaining caller of genpd_poweron() is conditionally compiled
based on CONFIG_PM_GENERIC_DOMAINS_OF, so we get a warning when that is
unset.
By moving the locking/unlocking of the genpd outside genpd_poweron(), thus
to the caller, genpd_poweron() becomes redundant.
Within this context let's then rename the wrapper function,
__genpd_poweron(), to genpd_poweron() as it will then be consistent with
its friend genpd_poweroff().
This change silence the warning about the unused function.

ALSA timer core framework has no sync point at stopping because it's
called inside the spinlock. Thus we need a sync point at close for
avoiding the stray timer task. This is simply done by implementing
the close callback just calling del_timer_sync(). (It's harmless to
call it unconditionally, as the core timer itself cares of the already
deleted timer instance.)

the frac div value 0x00809015 set to the CRU_CLKSEL7_CON will cause

We increase the mclk_fs to 512, will get the mclk = 512 * 8000 =

This patch adds the needed spi node for rk3036 dts.
We have to use the 4 bus emmc to work if someone want to support
the spi devices, since the pins are re-used by emmc data[5-8] and spi.
In some caseswe need to support the spi devices, that will waste the
emmc performance.
Moment, the kylin/evb hasn't the spi devices to work, so maybe we need wait
the new required to enable in kylin/evb board.
Anyway, the spi should be needed land in rk3036 dts.

The clk-vt8500.c driver would previously enter an endless loop
when invalid settings got requested, this was now fixed. However,
the driver will now return uninitialized data for a subset of those
cases instead, as the gcc correctly warns:
clk/clk-vt8500.c: In function 'wm8650_find_pll_bits':
clk/clk-vt8500.c:423:12: error: 'best_div2' may be used uninitialized in this function [-Werror=maybe-uninitialized]
*divisor2 = best_div2;
^
clk/clk-vt8500.c:422:12: error: 'best_div1' may be used uninitialized in this function [-Werror=maybe-uninitialized]
*divisor1 = best_div1;
^
clk/clk-vt8500.c:421:14: error: 'best_mul' may be used uninitialized in this function [-Werror=maybe-uninitialized]
*multiplier = best_mul;
This reworks the error handling in the driver so we now return
-EINVAL from clk_round_rate() and clk_set_rate() when we get
impossible inputs.

Currently, clk_register() never checks a circular parent looping,
but clock providers could register such an insane clock topology.
For example, "clk_a" could have "clk_b" as a parent, and vice versa.
In this case, clk_core_reparent() creates a circular parent list
and __clk_recalc_accuracies() calls itself recursively forever.
The core infrastructure should be kind enough to bail out, showing
an appropriate error message in such a case. This helps to easily
find a bug in clock providers. (uh, I made such a silly mistake
when I was implementing my clock providers first. I was upset
because the kernel did not respond, without any error message.)
This commit adds a new helper function, __clk_is_ancestor(). It
returns true if the second argument is a possible ancestor of the
first one. If a clock core is a possible ancestor of itself, it
would make a loop when it were registered. That should be detected
as an error.

The translation from the index into clk_core is done by
clk_core_get_parent_by_index(). The if-block for num_parents == 1
case is duplicating the code in the clk_core_get_parent_by_index().
Drop the "if (num_parents == 1)" from the special case. Instead,
set the index to zero if .get_parent() is missing.

added a dependency on the compress-cpu-dai channel_min field
which was removed earlier by commit 77095796

The net result was a regression at probe on all Atom platforms

Fix by adding explicit initialization for channel_min to 1
