Samsung DTS ARM64 changes for v6.20

1. ExynosAutov920:
 - Add MFD clock controller node.

2. Google GS101:
 - Add True Random Number Generator (TRNG) and OTP nvmem nodes.
 - Correct the PMU (Power Management Unit) compatibles by dropping
   fallback to syscon.  The PMU on Samsung devices serves the role of
   syscon, however on GS101 it cannot be used via standard Linux syscon
   interface, because register accesses require custom regmap.  It was
   simply never correctly working with "syscon" compatible fallback.
 - Add phandles to System Registers SYSREG blocks in clock controllers,
   necessary for enabling automatic clock control later.

Add support for the TRNG found on GS101. It works well with the current
exynos850 TRNG support.

The TRNG controller can be part of a power domain, allow the relevant
property 'power-domains'.

   - Drop obsolete db8500-thermal.txt

   - Treewide clean-up of extra blank lines and inconsistent quoting

     helpers and convert users treewide

   - Fix bounds checking of address properties in FDT code. Rework the
     code to have a single implementation of the bounds checks.

   - Rework of_irq_init() to ignore any implicit interrupt-parent (i.e.
     in a parent node) on nodes without an interrupt. This matches the

e00fc3d6e7 dt-bindings: rng: add binding for Rockchip RK3588 RNG
The Rockchip RK3588 SoC has two hardware RNGs accessible to the
non-secure world: an RNG in the Crypto IP, and a standalone RNG that is
new to this SoC.

Add a binding for this new standalone RNG. It is distinct hardware from
the existing rockchip,rk3568-rng, and therefore gets its own binding as
the two hardware IPs are unrelated other than both being made by the
same vendor.

The RNG is capable of firing an interrupt when entropy is ready.

The reset is optional, as the hardware does a power-on reset, and
functions without the software manually resetting it.

 - The vmgenid driver can now be bound using device tree, rather than

  dt-bindings: rng: Add vmgenid support
  virt: vmgenid: change implementation to use a platform driver
2024-05-18 10:51:35 -07:00
Sudan Landge
a4aded1ff5 dt-bindings: rng: Add vmgenid support
Virtual Machine Generation ID driver was introduced in commit
af6b54e2b5 ("virt: vmgenid: notify RNG of VM fork and supply
generation ID"), as an ACPI only device.

VMGenID specification http://go.microsoft.com/fwlink/?LinkId=260709
defines a mechanism for the BIOS/hypervisors to communicate to the
virtual machine that it is executed with a different configuration (e.g.
snapshot execution or creation from a template).  The guest operating
system can use the notification for various purposes such as
re-initializing its random number generator etc.

As per the specs, hypervisor should provide a globally unique
identified, or GUID via ACPI.

This patch tries to mimic the mechanism to provide the same
functionality which is for a hypervisor/BIOS to notify the virtual
machine when it is executed with a different configuration.

As part of this support the devicetree bindings requires the hypervisors
or BIOS to provide a memory address which holds the GUID and an IRQ
which is used to notify when there is a change in the GUID.  The memory
exposed in the DT should follow the rules defined in the vmgenid spec
mentioned above.

Reason for this change: Chosing ACPI or devicetree is an intrinsic part
of an hypervisor design.  Without going into details of why a hypervisor
would chose DT over ACPI, we would like to highlight that the
hypervisors that have chose devicetree and now want to make use of the
vmgenid functionality cannot do so today because vmgenid is an ACPI only
device.  This forces these hypervisors to change their design which
could have undesirable impacts on their use-cases, test-scenarios etc.

The point of vmgenid is to provide a mechanism to discover a GUID when
the execution state of a virtual machine changes and the simplest way to
do it is pass a memory location and an interrupt via devicetree.  It
would complicate things unnecessarily if instead of using devicetree, we
try to implement a new protocol or modify other protocols to somehow
provide the same functionility.

We believe that adding a devicetree binding for vmgenid is a simpler,
better alternative to provide the same functionality and will allow such
hypervisors as mentioned above to continue using devicetree.

More references to the vmgenid specs are found below.

02ec75edaa dt-bindings: treewide: add access-controllers description
access-controllers is an optional property that allows a peripheral to
refer to one or more domain access controller(s).

Description of this property is added to all peripheral binding files of
the peripheral under the STM32 firewall controller. It allows an accurate
representation of the hardware, where various peripherals are connected
to a firewall bus. The firewall can then check the peripheral accesses
before allowing its device to probe.

d7e8c41016 dt-bindings: rng: omap_rng: Drop requirement for clocks
For K3 devices the clock fed into the RNG module is shared with the rest
of the Crypto module, it is not dedicated to the RNG module and cannot be
controlled by the RNG driver. The driver does not require this clock to
always be defined and the DT binding should not force it either.

Remove this so we can start dropping out the clock properties as needed.

4e71ed9853 dt-bindings: Fix properties without any type
Now that the schema tools can extract type information for all
properties (in order to decode dtb files), finding properties missing
any type definition is fairly trivial though not yet automated.

Fix the various property schemas which are missing a type. Most of these
tend to be device specific properties which don't have a vendor prefix.
A vendor prefix is how we normally ensure a type is defined.
