Make the entire combination of plls to be one single clock. The parents used
for bypasses are specified each as an index in the parents list.
The determine_rate does a lookup throughout all the possible combinations
for all the divs and returns the best possible 'setup' which in turn is used
by set_rate later to set up all the divs and bypasses.

On NXP's i.MX SoCs with system controller inside, CPU frequency
scaling can ONLY be done by system controller firmware, and it
can ONLY be requested from secure mode, so Linux kernel has to
call ARM SMC to trap to ARM-Trusted-Firmware to request system
controller firmware to do CPU frequency scaling.

This patch adds i.MX system controller CPU frequency scaling support,
it reuses cpufreq-dt driver and implement the CPU frequency scaling
inside SCU clock driver.

When we add a new GENEVE device with IPv6 remote, checking only for
IS_ENABLED(CONFIG_IPV6) is not enough as we may disable IPv6 in the

cause a NULL pointer dereference.

v2:
- don't mix declarations and code (reported by Stefano Brivio, Eric Dumazet)
- there's no need to use in6_dev_get() as we only need to check that

There was a divergence between Linux and ACPICA on the definition of
ACPI_DEBUG_DEFAULT. This divergence was solved by taking ACPICA's
definition in 4c1379d7. After resolving the divergence, it was
clear that Linux users wanted to use their old set of debug flags.
This change fixes the divergence by setting these debug flags during
acpi_early_init() rather than during global variable initialization
in acpixf.h (owned by ACPICA).

There are at least four different parts with the same Vendor and Device
ID ([16c3:abcd]):

  1) Synopsys HAPS USB3 controller
  2) Synopsys PCIe Root Port in Freescale/NXP i.MX6Q (reported by Lucas)
  3) Synopsys PCIe Root Port in Freescale/NXP i.MX6QP (reported by Lukas)
  4) Synopsys PCIe Root Port in Freescale/NXP i.MX7D (reported by Trent)

The HAPS USB3 controller has a Class Code of PCI_CLASS_SERIAL_USB_XHCI,
which means the XHCI driver would normally claim it.  Previously,
quirk_synopsys_haps() changed the Class Code of all [16c3:abcd] devices,
including the Root Ports, to PCI_CLASS_SERIAL_USB_DEVICE to prevent the
XHCI driver from claiming them so dwc3-haps can claim them instead.

Changing the Class Code of the Root Ports prevents the PCI core from
handling them as bridges, so devices below them don't work.

Restrict the quirk so it only changes the Class Code for devices that start
with the PCI_CLASS_SERIAL_USB_XHCI Class Code, leaving the Root Ports
alone.

bio_trim() has an early return, which makes it _not_ idempotent, if the
offset is 0 and the bio's bi_size already matches the requested size.
Prior to DM, all users of bio_trim() were fine with this.  But DM has
exposed the fact that bio_trim()'s early return is incompatible with a
cloned bio whose integrity payload must be trimmed via
bio_integrity_trim().

Fix this by reverting DM back to doing the equivalent of bio_trim() but
in an idempotent manner (so bio_integrity_trim is always performed).

Follow-on work is needed to assess what benefit bio_trim()'s early
return is providing to its existing callers.
