This driver provides an access to EEPROM of IDT PCIe-switches. IDT PCIe-
switches expose a simple SMBus interface to perform IO-operations from/to
EEPROM, which is located at private (so called Master) SMBus. The driver
creates a simple binary sysfs-file to have an access to the EEPROM using
the SMBus-slave interface in the i2c-device susfs-directory:
/sys/bus/i2c/devices/<bus>-<devaddr>/eeprom
In case if read-only flag is specified at dts-node of the device, User-space
applications won't be able to write to the EEPROM sysfs-node.
Additionally IDT 89HPESx SMBus interface has an ability to read/write
values of device CSRs. This driver exposes debugfs-file to perform simple
IO-operations using that ability for just basic debug purpose. Particularly
the next file is created in the specific debugfs-directory:
/sys/kernel/debug/idt_csr/
Format of the debugfs-file value is:
$ cat /sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>;
<CSR address>:<CSR value>
So reading the content of the file gives current CSR address and it value.
If User-space application wishes to change current CSR address, it can just
write a proper value to the sysfs-file:
$ echo "<CSR address>" >
/sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>
If it wants to change the CSR value as well, the format of the write
operation is:
$ echo "<CSR address>:<CSR value>" > \
/sys/kernel/debug/idt_csr/<bus>-<devaddr>/<devname>;
CSR address and value can be any of hexadecimal, decimal or octal format.

The at24 driver doesn't check if the chip is functional in its probe
function. This leads to instantiating devices that are not physically
present. For example the cape EEPROMs for BeagleBone Black are defined
in the device tree at four addresses on i2c2, but normally only one of
them is present.
If the userspace doesn't know the location in advance, it will need to
check if reading the nvmem attributes fails to determine which EEPROM
is actually there.
Try to read a single byte in probe() and bail-out with -ENODEV if the
read fails.

Add a new read function to the at24 driver allowing to retrieve the

These chips can be instantiated similarily to the at24cs family,
except that there's no way of having access to both the serial number
and the mac address at the same time - the user must instantiate
either an at24cs or at24mac device as both special memory areas are
accessible on the same slave address.

The chips from the at24cs family have two memory areas - a regular
read-write block and a read-only area containing the serial number.
The latter is visible on a different slave address (the address of the
rw memory block + 0x08). In order to access both blocks the user needs
to instantiate a regular at24c device for the rw block address and a
corresponding at24cs device on the serial number block address.
Add a function that allows to access the serial number and assign it
to at24->read_func if the chip allows serial number read operations
and the driver was passed the relevant flag for this device.

Compatible at93xx46 devices from both Microchip and Atmel expect a
word-based address, regardless of whether the device is strapped for 8-

reading or writing at a specific location is always specified in terms
of bytes.

parameter to account for this difference between a byte offset and a
word-based address.
