Merge tag 'sunxi-clk-fixes-for-5.4-1' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-fixes

clk: sunxi-ng: a80: fix the zero'ing of bits 16 and 18
clk: sunxi: Fix operator precedence in sunxi_divs_clk_setup
Commit 3d8598fb9c ("clk: ti: clkctrl: use fallback udelay approach if
timekeeping is suspended") added handling for cases when timekeeping is
suspended. But looks like we can still get occasional "failed to enable"
errors on the PM runtime resume path with udelay() returning faster than
expected.
With ti-sysc interconnect target module driver this leads into device
failure with PM runtime failing with "failed to enable" clkctrl error.
Let's fix the issue with a delay of two times the desired delay as in
often done for udelay() to account for the inaccuracy.

The existing width field used to check divider validity does not provide
enough protection against bad values. For example, if max divider value
is 4, the smallest all-1 bitmask that can hold this value is 7, which
allows values higher than 4 to be used. This typically causes
unpredictable results with hardware. So far this issue hasn't been
noticed as most of the dividers actually have maximum values which fit
the whole bitfield, but there are certain clocks for which this is a
problem, like dpll4_m4 divider on omap3 devices.
Thus, convert the whole validity logic to use min,max and mask values
for determining if a specific divider is valid or not. This prevents
the odd cases where bad value would otherwise be written to a divider
config register.

During cpu frequency switching the main "CLK_ARM" is reparented to an
intermediate "step" clock. On imx8mm and imx8mn the 24M oscillator is
used for this purpose but it is extremely slow, increasing wakeup
latencies to the point that i2c transactions can timeout and system
becomes unresponsive.
Fix by switching the "step" clk to SYS_PLL1_800M, matching the behavior
of imx8m cpufreq drivers in imx vendor tree.
This bug was not immediately apparent because upstream arm64 defconfig
uses the "performance" governor by default so no cpufreq transitions
happen.

As the .round_rate() callback returns a long clock rate, it cannot
return clock rates that do not fit in signed long, but do fit in
unsigned long. Hence switch the SD clocks on R-Car Gen3 from the old
.round_rate() callback to the newer .determine_rate() callback, which
does not suffer from this limitation.
This includes implementing range checking.

Similar to MMP2, which this patch is based on. Known differencies from MMP2
are:
* Two PJ4B cores instead of one PJ4
* Tauros 3 L2 cache controller instead of Tauros 2
* A GIC interrupt controller optionally used instead of the MMP one
* A TWD local timer
* Different USB2 PHY
* A USB3 SS controller
* More interrupt muxes
Hard to tell what else is different, because documentation is not
available.

Add sm1 support the axg audio clock controllers. This new version is
indeed derived from the previous generation, as always, adding a few
new clocks to the mix.
The number of gates now exceeds 32 and do not fit in a single register.
Unfortunately, designers chose to introduce the new gate register
immediately after the original one, at the beginning of the register
space, shifting all the master clock register offsets.
The sm1 also introduce a few mux and divider on the top clock path,
possibly to lower the peripheral clocks of the audio blocks if
necessary.

The peripheral clock on the sm1 goes through some muxes
and dividers before reaching the audio gates. To model that,
without repeating our self too much, the "top" clock signal
is introduced and will serve as a the parent of the gates.
On the axg and g12a, the top clock is just a pass-through to
the audio peripheral clock provided by the main controller.

Rearrange the macro definition of the clocks of the axg-audio
controller. Also, the sm1 variant will feature tiny modification
of different blocks in this controller. Because of that, we need
to fallback to the old way of defining parent for some of the
clocks, using signal name.

Armada 3700 PCIe IP relies on the PCIe clock managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their registers at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().
Device link support in the clock framework enforce that the clock
driver's resume() callback will be called before the PCIe
driver's. But, any resume_noirq() callback will be called before all
the registered resume() callbacks.
The solution to support PCIe resume operation is to change the
"priority" of this clock driver PM callbacks to "_noirq()".

Here are fixes for omaps to deal with few regressions, and to fix
more boot time errors and warnings:
- The recent ti-sysc interconnect target module driver changes had
incorrect clock bits for both clocks and dts that cause warnings
- For omap3-gta04, gpio changes caused the LCD to break a while back,
and after discussing things the right fix is to set spi-cs-high
- Recent omapdrm changes to use generic panels caused tfp410 to be
disabled as we now must enable the generic support for it in
defconfig
- Recent omapdrm and backlight changes also finally made droid4 LCD
to work, so let's enable it in the defconfig it can be used out
of the box. This is not strictly a fix, but we still also have the
older CONFIG_MFD_TI_LMU options available so this cuts down the
confusion for trying to guess which display and which backlight
is needed
- Recent ti-sysc interconnect target module changes need the gpio
module disabled on some boards, but this now needs to happen at
the module level, not at the gpio driver level
- Recent changes to probe system timers with ti-sysc caused warnings
about mismatch in syconfig registers, so let's configure the option
for RESET_STATUS as available in the TRMs
- Recent changes to probe LCDC with ti-sysc caused warnings about
mismatch in sysconfig registers, so let's configure the missing
idlemodes for both platform data and dts as documented in TRMs
- Since we moved mach-omap2 to probe with device tree, we've been
getting voltage controller warnings. Turns out this code is no
longer needed, so let's just remove omap2_set_init_voltage() to
get rid of the pointless warnings
- Configure am4372 dispc memory bandwidth to avoid underflow errors
