8cf61051ae drivers: mediatek: Fix error handling in mtk_i2c_do_transfer
Errors were handled only if an I2C transfer timed out
and received a NACK which is very unlikely. This commit
changes the condition such that errors are handled if
an I2C transfer times out or received a NACK.

c5b42e3e9e net: sni_netsec: Add workaround for timeout error
The NETSEC GMAC occasionally falls into a weird state where
MAC_REG_DESC_SOFT_RST has never been cleared and shows errors like the
below when networking commands are issued:

    => ping 192.168.1.1
    ethernet@522d0000 Waiting for PHY auto negotiation to complete... done
    netsec_wait_while_busy: timeout
    Using ethernet@522d0000 device

    ARP Retry count exceeded; starting again
    ping failed; host 192.168.1.1 is not alive

It happens on not only 'ping' but also 'dhcp', 'tftp' and so on.

Luckily, restarting the NETSEC GMAC and trying again seems to fix the
problematic state. So first ensure that we haven't entered the state by
checking MAC_REG_DESC_SOFT_RST to be cleared; otherwise, restarting
NETSEC/PHY and trying again would work as a workaround.

250454c59b i2c: mvtwsi: reset controller if stuck in "bus error" state
The MVTWSI controller can act either as a master or slave device. When
acting as a master, the FSM is driven by the CPU. As a slave, the FSM is
driven by the bus directly. In what is (apparently) a safety mechanism,
if the bus transitions our FSM in any improper way, the FSM goes to a
"bus error" state (0x00). I could find no documented or experimental way
to get the FSM out of this state, except for a controller reset.

Since U-Boot only uses the MVTWSI controller as a bus master, this
feature only gets in the way: we do not care what happened on the bus
previously as long as the bus is ready for a new transaction. So, when
trying to start a new transaction, check for this state and reset the
controller if necessary.

Note that this should not be confused with the "deblocking" technique
(used by the `i2c reset` command), which involves pulsing SCL repeatedly
if SDA is found to be held low, in an attempt to force the bus back to
an idle state. This patch only resets the controller in case something
else had previously upset it, and (in principle) results in no
externally-observable change in behavior.

d7009faa09 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
values for input schmitt setting.

f16a48fec9 arm_ffa: introduce armffa command
Provide armffa command showcasing the use of the U-Boot FF-A support

armffa is a command showcasing how to invoke FF-A operations.
This provides a guidance to the client developers on how to
call the FF-A bus interfaces. The command also allows to gather secure
partitions information and ping these  partitions. The command is also
helpful in testing the communication with secure partitions.

For more details please refer to the command documentation [1].

A Sandbox test is provided for the armffa command.

a09852d862 arm_ffa: introduce sandbox FF-A support
Emulate Secure World's FF-A ABIs and allow testing U-Boot FF-A support

Features of the sandbox FF-A support:

- Introduce an FF-A emulator
- Introduce an FF-A device driver for FF-A comms with emulated Secure World
- Provides test methods allowing to read the status of the inspected ABIs

The sandbox FF-A emulator supports only 64-bit direct messaging.

39d383bdac 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].

718f1d414e usb: gadget: ether: Handle gadget driver registration in probe and remove
Move the ethernet gadget driver registration and removal from ethernet
bind and unbind callbacks into driver DM probe and remove callbacks.
This way, when the driver is bound, which is triggered deliberately
using 'bind' command, the USB ethernet gadget driver is instantiated
and bound to the matching UDC. In reverse, when the driver is unbound,
which is again triggered deliberately using 'unbind' command, the USB
ethernet gadget driver instance is removed.

Effectively, this now behaves like running either 'ums' or 'dfu' or
any other commands utilizing USB gadget functionality.

This also drops use of usb_gadget_release() and moves the use of
usb_gadget_initialize() into usb_ether_init() used only by legacy
platforms that do not use 'bind' command properly yet. Those have
no place in drivers.
