If IC_EMPTYFIFO_HOLD_MASTER_EN parameter is 0, "Stop" and "Repeated Start"
bits in command register do not exist, thus it is impossible to send
several consecutive write messages in a single hardware batch. The
existing implementation worked with such configuration incorrectly:
all consecutive write messages are joined into a single message without
any Start/Stop or Repeated Start conditions. For example, the following
command:
i2ctransfer -y 0 w1@0x55 0x00 w1@0x55 0x01
does the same as
i2ctransfer -y 0 w2@0x55 0x00 0x01
In i2c_dw_msg_is_valid(), we ensure that we do not have such sequence
of messages requiring a RESTART, aborting the transfer on controller
that cannot emit them explicitly.
This behavior is activated by compatible entries because the state of
the IC_EMPTYFIFO_HOLD_MASTER_EN parameter cannot be detected at runtime.
The new flag emptyfifo_hold_master reflects the state of the parameter,
it is set to true for all controllers except those found in Mobileye
SoCs. For now, the controllers in Mobileye SoCs are the only ones known
to need the workaround. The behavior of the driver is left unmodified
for other controllers.
There is another possible problem with this controller configuration:
When the CPU is putting commands to the FIFO, this process must not be
interrupted because if FIFO buffer gets empty, the controller finishes
the I2C transaction and generates STOP condition on the bus.
If we continue writing the remainder of the message to the FIFO, the
controller will start emitting a new transaction with those data. This
turns a single message into multiple I2C transactions. To protect against
FIFO underrun, two changes are done:
First we flag the interrupt with IRQF_NO_THREAD, to prevent it from
running in a thread on PREEMPT-RT kernel. This ensures that we are
not interrupted when filling the FIFO as it is very time-senstive. For
example, being preempted after writing a single byte in the FIFO with
a 1MHz bus gives us only 18µs before an underrun. DMA would allow us
to keep the interrupt threaded but it is not available on Mobileye SoC
for I2C.
Second in i2c_dw_process_transfer(), we abort if a STOP is detected
while a read or a write is in progress. This can occur when processing
a message larger than the FIFO. In that case the message is processed in
parts, and rely on the TX EMPTY interrupt to refill the FIFO when it gets
below a threshold. If servicing this interrupt is delayed for too long,
it can trigger a FIFO underrun, thus an unwanted STOP.

Add the support of the I2C_M_STOP flag in i2c_msg by splitting
i2c_dw_xfer() in two: __i2c_dw_xfer_one_part() for the core transfer logic
and i2c_dw_xfer() for handling the high-level transaction management.
In detail __i2c_dw_xfer_one_part() starts a transaction and wait for its
completion, either with a STOP on the bus or an error. i2c_dw_xfer()
loops over the messages to search for the I2C_M_STOP flag and calls
__i2c_dw_xfer_one_part() for each part of the messages up to a STOP or
the end of the messages array.
i2c_dw_xfer() takes care of runtime PM and holds the hardware lock on
the bus while calling __i2c_dw_xfer_one_part(), this allows grouping
multiple accesses to device that support a STOP in a transaction when
done via i2c_dev I2C_RDWR ioctl.
Also, now that we have a lookup of the messages in i2c_dw_xfer() prior
to each transaction, we use it to make sure the messages are valid for
the transaction, via a new function i2c_dw_msg_is_valid(). We check
that the target address does not change before starting the transaction
instead of aborting the transfer while it is happening, as it was done
in i2c_dw_xfer_msg(). The target address can only be changed after an
I2C_M_STOP flag, i.e after a STOP on the i2c bus.
The I2C_FUNC_PROTOCOL_MANGLING flag is added to the list of
functionalities supported by the controller, except for the AMD NAVI
i2c controller which uses its own xfer() function and is left untouched.

The DesignWare I2C can not be operated as I2C master and
I2C slave simultaneously, but that does not actually mean
master and slave modes can not be supported at the same
time. It just means an explicit mode swap needs to be
executed when the mode is changed. The DesignWare I2C
documentation actually describes a couple of cases where the
mode is excepted to be changed.
The I2C master will now always be supported. Both modes are
now always configured in i2c_dw_configure(), but the slave
mode will continue to be available only when the Kconfig
option I2C_SLAVE is enabled.
The driver will now start in master mode and then swap to
slave mode when a slave device is registered. After a slave
device is registered, the controller is swapped to master
mode when a transfer in master mode is started and then back
to slave mode again after the transfer is completed.
The DesignWare I2C can now be used with protocols such as
MCTP (drivers/net/mctp/mctp-i2c.c) and IPMI
(drivers/char/ipmi/) that require support for both I2C
master and I2C slave. It is now also possible to support the
SMBus Host Notification Protocol as I2C master if needed.

On i.MX8QXP/8QM SoCs, both the lvds/mipi and lvds/mipi-lpi2c power domains
must enter low-power mode during runtime suspend to achieve deep power
savings.
LPI2C resides in the lvds-lpi2c/mipi-lpi2c power domain, while its IRQ is
routed through an irqsteer located in the lvds/mipi power domain. The LPI2C
clock source comes from an LPCG within the lvds-lpi2c domain.
For example, the hierarchy for lvds0 and lvds0-lpi2c0 domains is:
┌───────────────────────┐
│ pm-domain : lvds0 │
│ │
│ ┌──────────────┐ │
│ │ irqsteer │ │
│ └───────▲──────┘ │
│ │irq │
│ │ │
└────────────┼──────────┘
┌────────────┼──────────┐
│ ┌───┼───┐ │
│ │lpi2c0 │ │
│ └───┬───┘clk │
│ ┌────────┼───────┐ │
│ │ LPCG │ │
│ └────────────────┘ │
│pm-domain:lvds0-lpi2c0 │
└───────────────────────┘
To allow these domains to power down in system runtime suspend:
- All irqsteer clients must release IRQs.
- All LPCG clients must disable and unprepare clocks.
Thus, LPI2C must:
- Free its IRQ during runtime suspend and re-request it on resume.
- Disable and unprepare all clocks during runtime suspend and prepare
and rne ble them on resume.
This enables the lvds/mipi domains to enter deep low-power mode,
significantly reducing power consumption compared to active mode.

catch all such issues going forward.

Commit 7bfe3b8ea6 ("Drivers: hv: Introduce mshv_vtl driver") added a
new generated header file for the offsets into the mshv_vtl_cpu_context
structure to be used by the low-level assembly code. But it didn't add
the .gitignore file to go with it, so 'git status' and friends will
mention it.
Let's add the gitignore file before somebody thinks that generated
header should be committed.
