Baikal-T1 CCU reference manual says that both xGMAC reference and xGMAC
PTP clocks are generated by two different wrappers with the same constant
divider thus each producing a 156.25 MHz signal. But for some reason both
of these clock sources are gated by a single switch-flag in the CCU
registers space - CCU_SYS_XGMAC_BASE.BIT(0). In order to make the clocks
handled independently we need to define a shared parental gate so the base
clock signal would be switched off only if both of the child-clocks are
disabled.
Note the ID is intentionally set to -2 since we are going to add a one
more internal clock identifier in the next commit.

Most likely due to copy-paste mistake the divider has been set to 10 while
according to the SoC reference manual it's supposed to be 8 thus having
PTP clock frequency of 156.25 MHz.

We have discovered random glitches during the system boot up procedure.
The problem investigation led us to the weird outcomes: when none of the
Renesas 5P49V6901 ports are explicitly enabled by the kernel driver, the
glitches disappeared. It was a mystery since the SoC external clock
domains were fed with different 5P49V6901 outputs. The driver code didn't
seem like bogus either. We almost despaired to find out a root cause when
the solution has been found for a more modern revision of the chip. It
turned out the 5P49V6901 clock generator stopped its output for a short
period of time during the VC5_OUT_DIV_CONTROL register writing. The same
problem was found for the 5P49V6965 revision of the chip and was
successfully fixed in commit fc336ae622df ("clk: vc5: fix output disabling
when enabling a FOD") by enabling the "bypass_sync" flag hidden inside
"Unused Factory Reserved Register". Even though the 5P49V6901 registers
description and programming guide doesn't provide any intel regarding that
flag, setting it up anyway in the officially unused register completely
eliminated the denoted glitches. Thus let's activate the functionality
submitted in commit fc336ae622df ("clk: vc5: fix output disabling when
enabling a FOD") for the Renesas 5P49V6901 chip too in order to remove the
ports implicit inter-dependency.

The PXA168 has a peculiar setup with the AXI clock enable control for
the SDHC controllers. The bits in the SDH0 register control the AXI
clock enable for both SDH0 and SDH1. Likewise, the bits in the SDH2
register control both SDH2 and SDH3. This is modeled with two new
parentless clocks that control the shared bits.
Previously, SDH0 had to be enabled in order for SDH1 to be used, and
when SDH1 was enabled, unused bits in the SDH1 register were being
controlled. This fixes those issues. A future commit will add support
for these new shared clocks to be enabled by the PXA168 SDHC driver.

- TWSI can be 31.2 MHz or 62.4 MHz
- KPC can be 32 kHz, 16 kHz, or 26 MHz
- PWM can be 13 MHz or 32 kHz

- The UART clocks can be 58.5 MHz or the UART PLL. Previously, the first
mux option was being calculated as 117 MHz, confirmed on hardware to
be incorrect.
- The SDHC clocks can be 48 MHz, 52 MHz, or 78 MHz. Previously, 48 MHz
and 52 MHz were swapped. 78 MHz wasn't listed as an option.
- The LCD clock can be 624 MHz or 312 Mhz. Previously, it was being
calculated as 312 MHz or 52 MHz.
- The CCIC clock can be 156 MHz or 78 MHz. Previously, it was being

Context:
1. all_tests_uml.config used to be UML specific back when users to
manually specify CONFIG_VIRTIO_UML=y to enable CONFIG_PCI=y.
2. --alltests used allyesconfig along with a curated list of options to
disable. It's only ever worked for brief periods of time and has
perennially been broken due to compile issues.
Now all_tests_uml.config should work across ~all architectures.
Let's instead use this to implement --alltests.
Note: if anyone was using all_tests_uml.config, this change breaks them.
I think that's unlikely since it was added in 5.19 and was a lot to
type: --kunitconfig=tools/testing/kunit/configs/all_tests_uml.config.
We could make it a symlink to the new name, but I don't think the
caution is warranted here.
