pinctrl: rockchip: Fix drive and input schmitt on RK3568

On RK3568 most pins have a configurable drive strength of level 0-5 and
some pins level 0-11. When rk3568_set_drive is called with a strength
value above 7 the drv value written to reg may overflow into the write
enable bits, resulting in a bad configuration.

This cause e.g. ethernet PHY on Radxa CM3-IO board not to work after
drive is configured according to the device tree.

  Could not get PHY for ethernet@fe010000: addr 0

Level 6-11 can be configured using a second reg for some pins, however
the drv value is reused resulting in lower 6 bits being written to reg.

Input schmitt is configured in 2-bit fields on RK3568 compared to
earlier generation and 2'b10 should be used to enable input schmitt.

Change to use regmap_update_bits with a rmask to fix the overflow issue
and closer match the linux driver. Bit shift the drv value used for the
second reg to configure drive strength level 6-11. Also write correct

To quote the author:
Adding support for Arm FF-A v1.0 (Arm Firmware Framework for Armv8-A) [A].

FF-A specifies interfaces that enable a pair of software execution
environments aka partitions to communicate with each other. A partition
could be a VM in the Normal or Secure world, an application in S-EL0, or
a Trusted OS in S-EL1.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed by
the PSCI driver.

   => dm tree

    Class     Index  Probed  Driver                Name
   -----------------------------------------------------------
   ...

    ffa                   0  [   ]   arm_ffa               |   `-- arm_ffa
   ...

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

This implementation of the specification provides support for Aarch64.

The FF-A driver uses the SMC ABIs defined by the FF-A specification to:

    - Discover the presence of secure partitions (SPs) of interest
    - Access an SP's service through communication protocols
      (e.g: EFI MM communication protocol)

The FF-A support provides the following features:

    - Being generic by design and can be used by any Arm 64-bit platform
    - FF-A support can be compiled and used without EFI
    - Support for SMCCCv1.2 x0-x17 registers
    - Support for SMC32 calling convention
    - Support for 32-bit and 64-bit FF-A direct messaging
    - Support for FF-A MM communication (compatible with EFI boot time)
    - Enabling FF-A and MM communication in Corstone1000 platform as a use case
    - A Uclass driver providing generic FF-A methods.
    - An Arm FF-A device driver providing Arm-specific methods and reusing the Uclass methods.
    - A sandbox emulator for Arm FF-A, emulates the FF-A side of the Secure World and provides
      FF-A ABIs inspection methods.
    - An FF-A sandbox device driver for FF-A communication with the emulated Secure World.
      The driver leverages the FF-A Uclass to establish FF-A communication.
    - Sandbox FF-A test cases.
    - A new command called armffa is provided as an example of how to access the
      FF-A bus

how to use the armffa command.

Please find at [D] an example of the expected boot logs when enabling

This feature allows accessing MM partitions services through
EFI MM communication protocol. MM partitions such as StandAlonneMM
or smm-gateway secure partitions which reside in secure world.

An MM shared buffer and a door bell event are used to exchange
the data.

The data is used by EFI services such as GetVariable()/SetVariable()
and copied from the communication buffer to the MM shared buffer.

The secure partition is notified about availability of data in the
MM shared buffer by an FF-A message (door bell).

On such event, MM SP can read the data and updates the MM shared
buffer with the response data.

The response data is copied back to the communication buffer and
consumed by the EFI subsystem.

MM communication protocol supports FF-A 64-bit direct messaging.

We tested the FF-A MM communication on the Corstone-1000 platform.

We ran the UEFI SCT test suite containing EFI setVariable, getVariable and
getNextVariable tests which involve FF-A MM communication and all tests
are passing with the current changes.

We made the SCT test reports (part of the ACS results) public following the

arm_ffa: introduce Arm FF-A support

Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0

The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.

This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.

The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.

All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.

Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.

The driver exports its operations to be used by upper layers.

Exported operations:

- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap

Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).

For more details please refer to the driver documentation [2].
