This corrects the use of depricated chipid and clock names, for which
support was finally dropped from the driver. It also ensures that the
DSI PLL is fed by the correct clock, now that it's being migrated to not

With commit c709135e ("pinctrl: at91-pio4: add support for slew-rate")
and commit cbde6c82 ("pinctrl: at91-pio4: Fix slew rate disablement")
the slew-rate is enabled by default for each configured pin. The datasheet
specifies at chapter "Output Driver AC Characteristics" that HSIO
drivers (use in SDMMCx and QSPI0 peripherals), don't have a slewrate
setting but are rather calibrated against an external 1% resistor mounted
on the SDMMCx_CAL or QSPI0_CAL pins. Depending on the target signal
frequency and the external load, it is possible to adjust their target
output impedance. Thus set slew-rate = <0> for SDMMC (QSPI is not enabled
at the moment in device tree).

GMAC's MDIO pins should be configured with slew-rate enabled, while the

In suspend/resume procedure for AT91 architecture different controllers
(PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings
for power saving. Commit f0bbf179 ("ARM: at91: pm: add self-refresh
support for sama7g5") introduced the access to RAMC PHY controller for
SAMA7G5. The access to this controller is done after RAMC ports are
closed, thus any TLB walk necessary for RAMC PHY virtual address will
fail. In the development branch this was not encountered. However, on
current kernel the issue is reproducible.

To solve the issue the previous mechanism of pre-loading the TLB with
the RAMC PHY virtual address has been used. However, only the addition
of this new pre-load breaks the functionality for ARMv5 based
devices (SAM9X60). This behavior has been encountered previously
while debugging this code and using the same mechanism for pre-loading
address for different controllers (e.g. pin controller, the assumption
being that other requested translations are replaced from TLB).

To solve this new issue the TLB flush + the extension of pre-loading
the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The
rest of the controllers should have been pre-loaded previously, anyway.

SAMA7G5-EK board has DDR3L type of memory soldered. This needs 1.35V. The
1.35V for DDR3L rail at run-time is selected by the proper configuration
on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended
the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of
configuration registers to provide proper voltages on its rail. Run-time
configuration registers could be configured differently than suspend
configuration register for MCP16502 (VSEL2 affects only run-time
configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK
switches to self-refresh. Even on self-refresh it needs to be powered by
a 1.35V rail. Thus, make sure the PMIC is configured properly when system
is suspended.

Commit 078fb7aa ("arm: dts: vexpress: Fix addressing issues with
'motherboard-bus' nodes") broke booting on a couple of 32-bit VExpress
boards. The problem is #address-cells size changed, but interrupt-map
was not updated. This results in the timer interrupt (and all the
other motherboard interrupts) not getting mapped.

As the 'interrupt-map' properties are all just duplicates across boards,
just move them into vexpress-v2m.dtsi and vexpress-v2m-rs1.dtsi.
Strictly speaking, 'interrupt-map' is dependent on the parent
interrupt controller, but it's not likely we'll ever have a different
parent than GICv2 on these old platforms. If there was one,
'interrupt-map' can still be overridden.

The 'motherboard-bus' node in Arm Ltd boards fails schema checks as
'simple-bus' child nodes must have a unit-address. The 'ranges' handling is
also wrong (or at least strange) as the mapping of SMC chip selects should
be in the 'arm,vexpress,v2m-p1' node rather than a generic 'simple-bus'
node. Either there's 1 too many levels of 'simple-bus' nodes or 'ranges'
should be moved down a level. The latter change is more simple, so let's do
that. As the 'ranges' value doesn't vary for a given motherboard instance,
we can move 'ranges' into the motherboard dtsi files.

Backup area is now switched to VDDIN33 at boot (with the help of
bootloader). When switching to backup mode we need to switch backup area

The 28NM DSI PLL driver for msm8960 calculates with a 27MHz reference
clock and should hence use PXO, not CXO which runs at 19.2MHz.

Note that none of the DSI PHY/PLL drivers currently use this "ref"
clock; they all rely on (sometimes inexistant) global clock names and
usually function normally without a parent clock.  This discrepancy will
be corrected in a future patch, for which this change needs to be in
place first.

Pull CPU hotplug updates from Thomas Gleixner:
 "Updates for the SMP and CPU hotplug:

   - Remove DEFINE_SMP_CALL_CACHE_FUNCTION() which is a left over of the
     original hotplug code and now causing trouble with the ARM64 cache
     topology setup due to the pointless SMP function call.

     It's not longer required as the hotplug callbacks are guaranteed to
     be invoked on the upcoming CPU.

   - Remove the deprecated and now unused CPU hotplug functions

   - Rewrite the CPU hotplug API documentation"

Pull misc driver fix from Greg KH:
 "Here is a single patch for 5.15-rc1, for the lkdtm misc driver.

  It resolves a build issue that many people were hitting with your
  current tree, and Kees and others felt would be good to get merged
  before -rc1 comes out, to prevent them from having to constantly hit
  it as many development trees restart on -rc1, not older -rc releases.

  It has NOT been in linux-next, but has passed 0-day testing and looks
  'obviously correct' when reviewing it locally :)"
