-Kernel driver spi-sc18is602
-===========================

-Description
------------
-
-This driver provides connects a NXP SC18IS602/603 I2C-bus to SPI bridge to the
-kernel's SPI core subsystem.
-
-The driver does not probe for supported chips, since the SI18IS602/603 does not
-support Chip ID registers. You will have to instantiate the devices explicitly.
-Please see Documentation/i2c/instantiating-devices.rst for details.
-
-
-Usage Notes
------------
-
-This driver requires the I2C adapter driver to support raw I2C messages. I2C
-adapter drivers which can only handle the SMBus protocol are not supported.
-
-The maximum SPI message size supported by SC18IS602/603 is 200 bytes. Attempts
-to initiate longer transfers will fail with -EINVAL. EEPROM read operations and
-similar large accesses have to be split into multiple chunks of no more than
-200 bytes per SPI message (128 bytes of data per message is recommended). This
-means that programs such as "cp" or "od", which automatically use large block
-sizes to access a device, can not be used directly to read data from EEPROM.
-Programs such as dd, where the block size can be specified, should be used
-instead.
