We are experiencing a problem with the i.MX I2C controller when
communicating with SMBus devices. We are seeing devices time-out because
the time between sending/receiving two bytes is too long, and the SMBus
device returns to the idle state. This happens because the i.MX I2C
controller sends and receives byte by byte. When a byte is sent or
received, we get an interrupt and can send or receive the next byte.
The current implementation sends a byte and then waits for an event
generated by the interrupt subroutine. After the event is received, the
next byte is sent and we wait again. This waiting allows the scheduler
to reschedule other tasks, with the disadvantage that we may not send
the next byte for a long time because the send task is not immediately
scheduled. For example, if the rescheduling takes more than 25ms, this
can cause SMBus devices to timeout and communication to fail.
This patch changes the behavior so that we do not reschedule the
send/receive task, but instead send or receive the next byte in the
interrupt subroutine. This prevents rescheduling and drastically reduces
the time between sending/receiving bytes. The cost in the interrupt
subroutine is relatively small, we check what state we are in and then
send/receive the next byte. Before we had to call wake_up, which is even
less expensive. However, we also had to do some scheduling, which
increased the overall cost compared to the new solution. The wake_up
function to wake up the send/receive task is now only called when an
error occurs or when the transfer is complete.

According to the i.MX8M Mini reference manual chapter "16.1.4.2
Generation of Start" it is only necessary to poll for bus busy and
arbitration lost in multi master mode. This helps to avoid rescheduling
while the i2c bus is busy and avoids SMBus devices to timeout. For
backward compatibility, the single-master property needs to be
explicitly set to disable the bus busy polling.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/i2c to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

It is common practice in the downstream and upstream CCI dt to set CCI
clock rates to 19.2 MHz. It appears to be fairly common for initial code to
set the CCI clock rate to 37.5 MHz.
Applying the widely used CCI clock rates from downstream ought not to cause
warning messages in the upstream kernel where our general policy is to
usually copy downstream hardware clock rates across the range of Qualcomm
drivers.
Drop the warning it is pervasive across CAMSS users but doesn't add any
information or warrant any changes to the DT to align the DT clock rate to
the bootloader clock rate.

If not clearing the BB (bus busy) condition in the BER (bus error)
interrupt, the driver causes a timeout and hence the i2c core
doesn't do the i2c transfer retry but returns the driver's return
value to the upper layer instead.
Clear the BB condition in the BER interrupt and a software flag is
used. The driver does an i2c recovery without causing the timeout
if the flag is set.

Originally the driver uses the XMIT bit in SMBnST register to decide
the upcoming i2c transaction. If XMIT bit is 1, then it will be an i2c
write operation. If it's 0, then a read operation will be executed.
In slave mode the XMIT bit can simply be used directly to set the state.
XMIT bit can be used as an indication to the current state of the state
machine during slave operation. (meaning XMIT = 1 during writing and
XMIT = 0 during reading).
In master operation XMIT is valid only if there are no bus errors.
For example: in a multi master where the same module is switching from
master to slave at runtime, and there are collisions, the XMIT bit
cannot be trusted.
However the maser already "knows" what the bus state is, so this bit
is not needed and the driver can just track what it is currently doing.

- Implementing mechanisms for registering and deregistering I2C slave

- Providing support for data transfer operations over ASF.
Additionally, include a 'select' Kconfig entry as the current patch

The AMD ASF controller is presented to the operating system as an ACPI
device. The AMD ASF driver can use ACPI to obtain information about the
ASF controller's attributes, such as the ASF address space and interrupt
number, and to handle ASF interrupts.
Currently, the piix4 driver assumes that a specific port address is
designated for AUX operations. However, with the introduction of ASF, the
same port address may also be used by the ASF controller. Therefore, a
check needs to be added to ensure that if ASF is advertised and enabled in
ACPI, the AUX port should not be configured.

Export the following i2c_piix4 driver functions as a library so that the
AMD ASF driver can utilize these core functionalities from the i2c_piix4
driver:
- piix4_sb800_region_request(): Request access to a specific SMBus region
on the SB800 chipset.
- piix4_sb800_region_release(): Release the previously requested SMBus
region on the SB800 chipset.
- piix4_transaction(): Handle SMBus transactions between the SMBus
controller and connected devices.
- piix4_sb800_port_sel(): Select the appropriate SMBus port on the SB800
chipset.
By making these functions available as a library, enable the AMD ASF
driver to leverage the established mechanisms in the i2c_piix4 driver,
promoting code reuse and consistency across different drivers.

Currently, `piix4_transaction()` accepts only one parameter, which is the
`i2c_adapter` information. This approach works well as long as SB800 SMBus
port accesses are confined to the piix4 driver. However, with the
implementation of a separate ASF driver and the varying address spaces
across drivers, it is necessary to change the function parameter list of
`piix4_transaction()` to include the port address. This modification
allows other drivers that use piix4 to pass the specific port details they
need to operate on.

Rework the read and write code paths in the driver to support operation
in atomic contexts in master mode. This change does not apply to slave
mode because there is no way to handle interruptions in that context.
Adjust the message timeout to include some extra time. For non-atomic
contexts, 500 ms is added to the timeout. For atomic contexts,
2000 ms is added because transfers happen in polled mode, requiring
more time to account for the polling overhead.
Similar changes have been implemented in other drivers, including:

They both have been in linux-next for a while with no reported
problems"
