f2f5cf78a3 ARM: at91: pm: add support for sama5d2 secure suspend
When running with OP-TEE, the suspend control is handled securely.
Suspend can be entered using PSCI support. Since the sama5d2 supports
multiple suspend modes, add a new CONFIG_ATMEL_SECURE_PM which will
send a SMC call to select the suspend mode at init time.

"atmel.pm_modes" boot argument is still supported for compatibility
purposes but the standby value is actually ignored since PSCI suspend
is used and it only support one mode (suspend).

0c9fd82117 ARM: at91: add code to handle secure calls
Since OP-TEE now has a more complete support for sama5d2, add necessary
code to perform SMC calls. The detection of OP-TEE is based on a
specific device-tree node path (/firmware/optee) such has done by some
other SoC. A check is added to avoid doing SMC calls without having
OP-TEE.

b7fc72c633 ARM: at91: pm: add quirks for pm
SoCs supporting ULP0 or ULP1 modes and variants of Cadence Ethernet IP
(controlled by macb driver) may behave buggy when Wake-on-Lan (WoL) is
configured and WoL packet is received while in ULP0/ULP1. On some SoCs
Ethernet interface is not working after resume. On other SoCs the CPU
goes to abort on resume path when switching execution from internal SRAM
to DRAM. For ULP1 + WoL the issue is related a particular restart
sequence of the internal clocks when resuming. These clocks are
automatically managed by PMC and may happen that GMAC peripheral clock
is restarted few clock cycles before internal clocks causing blocking
of Ethernet's DMA. As a consequence Ethernet TX transactions are stopped
and RX transactions are partially stopped (packets are received by MAC,
RX counters incremented but the data is not transferred to DRAM). The
workaround for this is to disable Ethernet's peripheral clock when
going to ULP1. Same behavior has been reproduced on ULP0 for some
platforms (SAMA5D2, SAMA5D3) and the same workaround solves the issue.

The problem has been solved on pm.c as quirk to avoid polluting the
MACB driver with AT91 specific issues as this driver is generic to
multiple vendors.

At probe pointers to struct device_node are retrieved and on the
at91_pm_enter() the quirk specifics are applied: for all Ethernet
interfaces that were parsed the peripheral clocks are disabled. A
special handling is done for modes in dns_modes mask as these are
considered modes that blocks the system if WoL packet are received
but for which applying quirk will lead to not waking up on WoL
packets: in situation where Ethernet interface(s) has suspend mode
in dns_modes mask and Ethernet interface(s) is the only available
wakeup source the suspend is canceled.

4e8988c634 soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0
The mmsys routing table of mt8195 vdosys0 has 2 DITHER components,
so mmsys need to add DDP_COMPONENT_DITHER1 and change all usages of
DITHER enum form DDP_COMPONENT_DITHER to DDP_COMPONENT_DITHER0.

But its header need to keep DDP_COMPONENT_DITHER enum
until drm/mediatek also changed it.

81c5a41d10 dt-bindings: arm: mediatek: mmsys: add mt8195 SoC binding
In the SoC before, such as mt8173, it has 2 pipelines binding to one
mmsys with the same clock driver and the same power domain.

In mt8195, there are 4 pipelines binding to 4 different mmsys, such as
vdosys0, vdosys1, vppsys0 and vppsys1.
Each mmsys uses different clock drivers and different power domain.

Since each mmsys has its own mmio base address, they could be identified
by their different address during probe time.

  - The @cpu member of struct cpuhp_cpu_state is initialized when the CPU
    hotplug thread for the upcoming CPU is created. That's too late because
    the creation of the thread can fail and then the following rollback
    operates on CPU0. Get rid of the CPU member and hand the CPU number to

Merge tag 'random-5.18-rc3-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator fixes from Jason Donenfeld:

 - Per your suggestion, random reads now won't fail if there's a page
   fault after some non-zero amount of data has been read, which makes
   the behavior consistent with all other reads in the kernel.

 - Rather than an inconsistent mix of random_get_entropy() returning an
   unsigned long or a cycles_t, now it just returns an unsigned long.

 - A memcpy() was replaced with an memmove(), because the addresses are
   sometimes overlapping. In practice the destination is always before
   the source, so not really an issue, but better to be correct than
   not.

* tag 'random-5.18-rc3-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random:
  random: use memmove instead of memcpy for remaining 32 bytes
  random: make random_get_entropy() return an unsigned long
  random: allow partial reads if later user copies fail
