Incremental linking is gone, so rename built-in.o to built-in.a, which
is the usual extension for archive files.
This patch does two things, first is a simple search/replace:
git grep -l 'built-in\.o' | xargs sed -i 's/built-in\.o/built-in\.a/g'
The second is to invert nesting of nested text manipulations to avoid
filtering built-in.a out from libs-y2:
-libs-y2 := $(filter-out %.a, $(patsubst %/, %/built-in.a, $(libs-y)))
+libs-y2 := $(patsubst %/, %/built-in.a, $(filter-out %.a, $(libs-y)))

Following are the major issues in current driver code
1. The current driver simply assumes the transfer completion
whenever its gets any non-error interrupts and then simply do the
polling of available/free bytes in FIFO.
2. The block mode is not working properly since no handling in
being done for OUT_BLOCK_WRITE_REQ and IN_BLOCK_READ_READ.
3. An i2c transfer can contain multiple message and QUP v2
supports reconfiguration during run in which the mode should be same
for all the sub transfer. Currently the mode is being programmed
before every sub transfer which is functionally wrong. If one message
is less than FIFO length and other message is greater than FIFO
length, then transfers will fail.
Because of above, i2c v2 transfers of size greater than 64 are failing
with following error message
i2c_qup 78b6000.i2c: timeout for fifo out full
To make block mode working properly and move to use the interrupts
instead of polling, major code reorganization is required. Following
are the major changes done in this patch
1. Remove the polling of TX FIFO free space and RX FIFO available
bytes and move to interrupts completely. QUP has QUP_MX_OUTPUT_DONE,
QUP_MX_INPUT_DONE, OUT_BLOCK_WRITE_REQ and IN_BLOCK_READ_REQ
interrupts to handle FIFO’s properly so check all these interrupts.
2. Determine the mode for transfer before starting by checking
all the tx/rx data length in each message. The complete message can be
transferred either in DMA mode or Programmed IO by FIFO/Block mode.
in DMA mode, both tx and rx uses same mode but in PIO mode, the TX and
RX can be in different mode.
3. During write, For FIFO mode, TX FIFO can be directly written
without checking for FIFO space. For block mode, the QUP will generate
OUT_BLOCK_WRITE_REQ interrupt whenever it has block size of available
space.
4. During read, both TX and RX FIFO will be used. TX will be used
for writing tags and RX will be used for receiving the data. In QUP,
TX and RX can operate in separate mode so configure modes accordingly.
5. For read FIFO mode, wait for QUP_MX_INPUT_DONE interrupt which
will be generated after all the bytes have been copied in RX FIFO. For
read Block mode, QUP will generate IN_BLOCK_READ_REQ interrupts
whenever it has block size of available data.
6. Split the transfer in chunk of one QUP block size(256 bytes)
and schedule each block separately. QUP v2 supports reconfiguration
during run in which QUP can transfer multiple blocks without issuing a
stop events.
7. Port the SMBus block read support for new code changes.

The BAM mode requires buffer for start tag data and tx, rx SG
list. Currently, this is being taken for maximum transfer length
(65K). But an I2C transfer can have multiple messages and each
message can be of this maximum length so the buffer overflow will
happen in this case. Since increasing buffer length won’t be
feasible since an I2C transfer can contain any number of messages
so this patch does following changes to make i2c transfers working
for multiple messages case.
1. Calculate the required buffers for 2 maximum length messages
(65K * 2).
2. Split the descriptor formation and descriptor scheduling.
The idea is to fit as many messages in one DMA transfers for 65K
threshold value (max_xfer_sg_len). Whenever the sg_cnt is
crossing this, then schedule the BAM transfer and subsequent
transfer will again start from zero.

Currently each message length in complete transfer is being
checked for determining DMA mode and if any of the message length
is less than FIFO length then non DMA mode is being used which
will increase overhead. DMA can be used for any length and it

Currently the i2c error handling in BAM mode is not working
properly in stress condition.
1. After an error, the FIFO are being written with FLUSH and
EOT tags which should not be required since already these tags
have been written in BAM descriptor itself.
2. QUP state is being moved to RESET in IRQ handler in case
of error. When QUP HW encounters an error in BAM mode then it
moves the QUP STATE to PAUSE state. In this case, I2C_FLUSH
command needs to be executed while moving to RUN_STATE by writing
to the QUP_STATE register with the I2C_FLUSH bit set to 1.
3. In Error case, sometimes, QUP generates more than one
interrupt which will trigger the complete again. After an error,
the flush operation will be scheduled after doing
reinit_completion which should be triggered by BAM IRQ callback.
If the second QUP IRQ comes during this time then it will call
the complete and the transfer function will assume the all the
BAM HW descriptors have been completed.
4. The release DMA is being called after each error which
will free the DMA tx and rx channels. The error like NACK is very
common in I2C transfer and every time this will be overhead. Now,
since the error handling is proper so this release channel can be
completely avoided.

The role of FLUSH and EOT tag is to flush already scheduled
descriptors in BAM HW in case of error. EOT is required only
when descriptors are scheduled in RX FIFO. If all the messages
are WRITE, then only FLUSH tag will be used.
A single BAM transfer can have multiple read and write messages.
The EOT and FLUSH tags should be scheduled at the end of BAM HW
descriptors. Since the READ and WRITE can be present in any order
so for some of the cases, these tags are not being written
correctly.
Following is one of the example
READ, READ, READ, READ
Currently EOT and FLUSH tags are being written after each READ.
If QUP gets NACK for first READ itself, then flush will be
triggered. It will look for first FLUSH tag in TX FIFO and will
stop there so only descriptors for first READ descriptors be
flushed. All the scheduled descriptors should be cleared to
generate BAM DMA completion.
Now this patch is scheduling FLUSH and EOT only once after all the
descriptors. So, flush will clear all the scheduled descriptors and
BAM will generate the completion interrupt.

The QUP BSLP BAM generates the following error sometimes if the
current I2C DMA transfer fails and the flush operation has been
scheduled
“bam-dma-engine 7884000.dma: Cannot free busy channel”
If any I2C error comes during BAM DMA transfer, then the QUP I2C
interrupt will be generated and the flush operation will be
carried out to make I2C consume all scheduled DMA transfer.
Currently, the same completion structure is being used for BAM
transfer which has already completed without reinit. It will make
flush operation wait_for_completion_timeout completed immediately
and will proceed for freeing the DMA resources where the
descriptors are still in process.

while on the ast2500 the chip selects are swapped.
Also clear the secondary boot bit during the machine restart operation.

The Nuvoton NPCM750 has a watchdog implemented as a single register
inside the timer peripheral.
This driver exposes that watchdog as a standard watchdog device with
coarse timeout intervals, limited by the combination of prescaler and
counter that is provided by the hardware. The calculation is taken from
the Nuvoton vendor tree.
The watchdog is left running if a bootloader had it going. The rate is
the one specified in the device tree, or the default value (obtained
from the datasheet).
There is a pre-timeout IRQ that is wired up. This timeout always occurs
1024 clocks before the timeout.
