commit c7c06a1532f3fe106687ac82a13492c6a619ff1c upstream.
Family 16h Model 30h SMBus controller needs the same port selection fix
as described and fixed in commit 0fe16195f891 ("i2c: piix4: Fix SMBus port
selection for AMD Family 17h chips")
commit 6befa3fde65f ("i2c: piix4: Support alternative port selection
register") also fixed the port selection for Hudson2, but unfortunately
this is not the exact same device and the AMD naming and PCI Device IDs
aren't particularly helpful here.
The SMBus port selection register is common to the following Families
and models, as documented in AMD's publicly available BIOS and Kernel
Developer Guides:
50742 - Family 15h Model 60h-6Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
55072 - Family 15h Model 70h-7Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
52740 - Family 16h Model 30h-3Fh (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS)
The Hudson2 PCI Device ID (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) is shared
between Bolton FCH and Family 16h Model 30h, but the location of the
SmBus0Sel port selection bits are different:
51192 - Bolton Register Reference Guide
We distinguish between Bolton and Family 16h Model 30h using the PCI
Revision ID:
Bolton is device 0x780b, revision 0x15
Family 16h Model 30h is device 0x780b, revision 0x1F
Family 15h Model 60h and 70h are both device 0x790b, revision 0x4A.
The following additional public AMD BKDG documents were checked and do
not share the same port selection register:
42301 - Family 15h Model 00h-0Fh doesn't mention any
42300 - Family 15h Model 10h-1Fh doesn't mention any
49125 - Family 15h Model 30h-3Fh doesn't mention any
48751 - Family 16h Model 00h-0Fh uses the previously supported
index register SB800_PIIX4_PORT_IDX_ALT at 0x2e

This endless clk warnings behaviour is well explained by Andrey Smirnov:
"Allocating DMA after registering I2C adapter can lead to infinite
probing loop, for example, consider the following scenario:
1. i2c_imx_probe() is called and successfully registers an I2C
adapter via i2c_add_numbered_adapter()
2. As a part of i2c_add_numbered_adapter() new I2C slave devices
are added from DT which results in a call to
driver_deferred_probe_trigger()
3. i2c_imx_probe() continues and calls i2c_imx_dma_request() which
due to lack of proper DMA driver returns -EPROBE_DEFER
4. i2c_imx_probe() fails, removes I2C adapter and returns
-EPROBE_DEFER, which places it into deferred probe list
5. Deferred probe work triggered in #2 above kicks in and calls
i2c_imx_probe() again thus bringing us to step #1"
So revert commit e1ab9a468e3b ("i2c: imx: improve the error handling in
i2c_imx_dma_request()") and restore the old behaviour, in order to
avoid regressions on existing setups.

[ Upstream commit 9f2e244d0a39eb437f98324ac315e605e48636db ]
Cypress USB Type-C CCGx controller firmware version 3.1.10
(which is being used in many NVIDIA GPU cards) has known issue of
not triggering interrupt when a USB device is hot plugged to runtime
resume the controller. If any GPU card gets latest kernel with runtime
pm support but does not get latest fixed firmware then also it should
continue to work and therefore a workaround is required to check for
any connector change event
The workaround is to request runtime resume of i2c client
which is UCSI Cypress CCGx driver. CCG driver will call the ISR
for any connector change event only if NVIDIA GPU has old
CCG firmware with the known issue.

This commit adds DMA mode transfer support for better performance.
Only AST2500 supports DMA mode under some limitations:
I2C is sharing the DMA H/W with UHCI host controller and MCTP
controller. Since those controllers operate with DMA mode only, I2C
has to use buffer mode or byte mode instead if one of those
controllers is enabled. Also make sure that if SD/eMMC or Port80
snoop uses DMA mode instead of PIO or FIFO respectively, I2C can't
use DMA mode.

Byte mode currently this driver uses makes lots of interrupt call
which isn't good for performance and it makes the driver very
timing sensitive. To improve performance of the driver, this commit
adds buffer mode transfer support which uses I2C SRAM buffer
instead of using a single byte buffer.

Currently we only create an I2C bus for the ports listed in the
device-tree for that master. There's no real reason for this since
we can discover the number of ports the master supports by looking
at the port_max field of the status register.
This patch re-works the bus add logic so that we always create buses
for each port, unless the bus is marked as unavailable in the DT. This
is useful since it ensures that all the buses provided by the CFAM I2C
master are accessible to debug tools.

The devm_gpiod_request_gpiod() call will add "-gpios" to
any passed connection ID before looking it up.
I do not think the reset GPIO on this platform is named
"reset-gpios-gpios" but rather "reset-gpios" in the device
tree, so fix this up so that we get a proper reset GPIO
handle.
Also drop the inclusion of the legacy GPIO header.

This driver does not support reading more than 255 bytes at once because
the register for storing the number of bytes to read is only 8 bits. Add
a max_read_len quirk to enforce this.
This was found when using this driver with the SFP driver, which was
previously reading all 256 bytes in the SFP EEPROM in one transaction.
This caused a bunch of hard-to-debug errors in the xiic driver since the
driver/logic was treating the number of bytes to read as zero.
Rejecting transactions that aren't supported at least allows the problem
to be diagnosed more easily.

Fix wrong order in probing routine initialization - field `base_addr'
is used before it's initialized. Move assignment of 'priv->base_addr`
to the beginning, prior the call to mlxcpld_i2c_read_comm().
Wrong order caused the first read of capability register to be executed
at wrong offset 0x0 instead of 0x2000. By chance it was a "good
garbage" at 0x0 offset.

i2c_new_dummy is typically called from the probe function of the
driver for the primary i2c client. It requires calls to
i2c_unregister_device in the error path of the probe function and
in the remove function.
This can be simplified by introducing a device-managed version.
Note the changed error case return value type: i2c_new_dummy returns
NULL whilst devm_i2c_new_dummy_device returns an ERR_PTR.
