In case of any error occurs after enabling the PM runtime framework
for the fsl-spdif-dai device, the next probing generates the
warning:
"fsl-spdif-dai 2004000.spdif: Unbalanced pm_runtime_enable!"
Add the error handling path to keep the PM runtime usage counter balanced.

Each spdif sample is qualified by the validity bit.
The bit shall be logic '0' if the audio sample is valid.
This commit configures the transmitter to always send '0' rather
than always send '1'.

The call flow:

- clk_prepare()
- clk_pm_runtime_get()

which impact the power consumption.
So we can't bind clock with regmap, then explicitly enable
clock when using. As we already enable all clock in
pm_runtime_resume, so only need to enable clock in probe.

Same as commit ce492b3b8f99cf9d2f807ec22d8805c996a09503
Subject: drm/fsl-dcu: use flat regmap cache
Using flat regmap cache instead of RB-tree to avoid the following
lockdep warning on driver load:
WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128
DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))
The RB-tree regmap cache needs to allocate new space on first
writes. However, allocations in an atomic context (e.g. when a
spinlock is held) are not allowed. The function regmap_write
calls map->lock, which acquires a spinlock in the fast_io case.
Since the driver uses MMIO, the regmap bus of type regmap_mmio
is being used which has fast_io set to true.

Since commit 035a61c314eb ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers. That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get(). This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place. The net change here is before commit
035a61c314eb the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.
That said, the struct clk pointer comparing in the code doesn't work any
more. Call helper function clk_is_match() instead to fix the problem.
