TI sysc driver changes for v4.20 merge window
This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device
detection happen mostly only if #define DEBUG is set. Few core devices still
need to be detected to set legacy quirks.
We also add support for booting am335x, am437x and dra7 SoCs with L4 devices
defined in device tree instead of legacy platform data.
And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
and dropping the custom functions that were attempting to work around
issues that really turned out to be child device driver related issues.
Apologies for a late pull request, debugging the suspend issues took a while
and I did not want to send these changes until that got sorted out.

As Grygorii Strashko pointed out, the runtime PM use count of the
children can be whatever at suspend and we should not use it. So
let's just suspend ti-sysc at noirq level and get rid of some code.
Let's also remove the PM_SLEEP ifdef and use __maybe_unused as the
PM code already deals with the ifdefs.

soc: qcom: geni: geni_se_clk_freq_match() should always accept multiples
The geni_se_clk_freq_match() has some strange semantics. Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then
...but callers should always be able to handle a clock that is a
multiple of the requested clock so mode #2 doesn't really make sense.
Let's change the semantics so that the non-exact match can also accept
multiples and then change the code to handle that.
The only caller of this code is the unlanded SPI driver [1] which
currently passes "exact = True", thus it should be safe to change the
semantics in this way. ...and, in fact, the SPI driver should likely
be modified to pass "exact = False" (with the new semantics) since
that will allow it to work with SPI devices that request a clock rate
that doesn't exactly match a rate we can make.

soc: qcom: geni: Don't ignore clk_round_rate() errors in geni_se_clk_tbl_get()
The function clk_round_rate() is defined to return a "long", not an
"unsigned long". That's because it might return a negative error
code. Change the call in geni_se_clk_tbl_get() to check for errors.
While we're at it, get rid of a useless init of "freq".
NOTE: overall the idea that we should iterate over clk_round_rate() to
try to reconstruct a table already present in the clock driver is
questionable. Specifically:
- This method relies on "clk_round_rate()" rounding up.
- This method only works if the table is sorted and has no duplicates.
...this patch doesn't try to fix those problems, it just makes the
error handling more correct.

This macro doesn't work, because it hides a local variable inside of the

Let's change this to be more explicit. Introduce three macros for the
major, minor, and step of the version, and require callers to pass the
version in to get the part of the version out. This way we don't hide
local variables inside macros and things are less evil overall.

Allwinner fixes - round 2
One additional fix regarding HDMI on the R40 SoC.
Based on preliminary tests and code dumps for the R40, it was thought
that the whole HDMI block was the same on the R40 and A64.
Recent tests regarding the A64 showed that this was not the case. The
HDMI PHY on the A64 only has one clock parent. How this occurs at the
hardware level is unclear, as Allwinner has not given any feedback on
this matter. Nevertheless it is clear that the hardware acts differently
between the A64 and R40 in such a way that the R40's HDMI PHY is not
backward compatible with the A64's. As such we need to drop the fallback
compatible string in the R40's device tree. This was added in v4.19-rc1.
