match table needs to be accessible in that function, which would require

as well should the need arise.

This version of the patch has been tested on an M1 Ultra Mac Studio,

Writes from I2C bus often fail when testing the i2c-designware-slave.c
with the slave-eeprom backend. The same writes work correctly when
testing with a real 24c02 EEPROM chip.

In the tests below an i2c-designware-slave.c instance with the
slave-eeprom backend is configured to act as a simulated 24c02 at
address 0x65 on an I2C host bus 6.

1. i2cset -y 6 0x65 0x00 0x55

Single byte 0x55 write into address 0x00. No data goes into simulated
EEPROM. Debug prints from the i2c_dw_irq_handler_slave():

0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4

2. i2ctransfer -y 6 w9@0x65 0x00 0xff-

Write 8 bytes with decrementing value starting from 0xff at address 0x00
and forward. Only some of the data goes into arbitrary addresses.
Content is something like below but varies:

00000000  f9 f8 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000050  00 00 00 00 00 00 ff fe  00 00 00 00 00 00 00 00  |................|
000000f0  00 00 00 00 00 00 00 00  00 00 00 00 00 fc fb fa  |................|

In this case debug prints were:

0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x1 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x714 : INTR_STAT=0x204
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x514 : INTR_STAT=0x4
0x1 STATUS SLAVE_ACTIVITY=0x0 : RAW_INTR_STAT=0x510 : INTR_STAT=0x0

Both cases show there is more data coming from the receive FIFO still
after detecting the STOP condition. This can be seen from interrupt
status bits DW_IC_INTR_STOP_DET (0x200) and DW_IC_INTR_RX_FULL (0x4).

Perhaps due interrupt latencies the receive FIFO is not read fast
enough, STOP detection happens synchronously when it occurs on the I2C
bus and the DW_IC_INTR_RX_FULL keeps coming as long as there are more
bytes in the receive FIFO.

Fix this by reading the receive FIFO completely empty whenever
DW_IC_INTR_RX_FULL occurs. Use RFNE, Receive FIFO Not Empty bit in the
DW_IC_STATUS register to loop through bytes in the FIFO.

While at it do not test the return code from i2c_slave_event() for the
I2C_SLAVE_WRITE_RECEIVED since to my understanding this hardware cannot
generate NACK to incoming bytes and debug print itself does not have
much value.

Some read types from I2C bus don't work correctly when testing the
i2c-designware-slave.c with the slave-eeprom backend. The same reads
work correctly when testing with a real 24c02 EEPROM chip.

In the following tests an i2c-designware-slave.c instance with the
slave-eeprom backend is configured to act as a simulated 24c02 at
address 0x65 on an I2C host bus 6:

1. i2cdump -y 6 0x65 b (OK)
   Random read. Each byte are read using a byte address write with a
   current address read in a same message.
2. i2cdump -y 6 0x65 c (OK, was NOK before commit 3b5f7f10 when it
                        was repeating the 1st byte)
   Repeated current address read. One byte address write message
   followed by repeated current address read messages.
3. i2cdump -y 6 0x65 i (NOK, each 32 byte block repeats the 1st byte of
                        block)
   Sequential read using SMBus Block Read. For each 32 byte block a byte
   address write followed by 32 sequental reads in a same message.

These findings are explained because the implementation has had a
mismatch between hardware interrupts and what I2C slave events should be
sent after those interrupts. Despite that the case 1 happened to have
always the I2C slave events sent to a right order with a right data
between backend and the I2C bus.

Hardware generates the DW_IC_INTR_RD_REQ interrupt when another host is
attempting to read and for sequential reads after. DW_IC_INTR_RX_DONE
occurs when host does not acknowledge a transmitted byte which is an
indication the end of transmission.

Those interrupts do not match directly with I2C_SLAVE_READ_REQUESTED and
I2C_SLAVE_READ_PROCESSED events which is how the code was and is
practically using them. The slave-eeprom backend increases the buffer
index with the I2C_SLAVE_READ_PROCESSED event and returns the data from
current index when receiving only the I2C_SLAVE_READ_REQUESTED event.

That explains the repeated bytes in case 3 and also case 2 before
commit 3b5f7f10 ("i2c: designware: slave should do WRITE_REQUESTED
before WRITE_RECEIVED").

Patch fixes the case 3 while keep cases 1 and 2 working with following
changes:

- First DW_IC_INTR_RD_REQ interrupt will change the state machine to
  read in progress state, send I2C_SLAVE_READ_REQUESTED event and
  transmit the first byte from backend
- Subsequent DW_IC_INTR_RD_REQ interrupts will send
  I2C_SLAVE_READ_PROCESSED events and transmit next bytes from backend
- STOP won't change the state machine. Otherwise case 2 won't work since
  we cannot distinguish current address read from sequentiel read
- DW_IC_INTR_RX_DONE interrupt is needless since there is no mechanism
  to inform it to a backend. It cannot be used to change state machine
  at the end of read either due the same reason than above
- Next host write to us will change the state machine from read to write
  in progress state
- STATUS_WRITE_IN_PROGRESS and STATUS_READ_IN_PROGRESS are considered
  now to be status flags not the state of the driver. This is how we
  treat them in i2c-designware-master.c

While at it do not test the return code from i2c_slave_event() for
I2C_SLAVE_READ_REQUESTED and I2C_SLAVE_READ_PROCESSED since it returns
always 0.
