* PCA9548, PCA9846, PCA9847, PCA9848 and PCA9849.
*
* These chips are all controlled via the I2C bus itself, and all have a
* single 8-bit register. The upstream "parent" bus fans out to two,
* four, or eight downstream busses or channels; which of these
* are selected is determined by the chip type and register contents. A
* mux can select only one sub-bus at a time; a switch can select any
* combination simultaneously.

/*
* I2C EEPROMs from most vendors are inexpensive and mostly interchangeable.
* Differences between different vendor product lines (like Atmel AT24C or
* MicroChip 24LC, etc) won't much matter for typical read/write access.
* There are also I2C RAM chips, likewise interchangeable. One example
* would be the PCF8570, which acts like a 24c02 EEPROM (256 bytes).
*
* However, misconfiguration can lose data. "Set 16-bit memory address"
* to a part with 8-bit addressing will overwrite data. Writing with too
* big a page size also loses data. And it's not safe to assume that the
* conventional addresses 0x50..0x57 only hold eeproms; a PCF8563 RTC
* uses 0x51, for just one example.
*
* Accordingly, explicit board-specific configuration data should be used
* in almost all cases. (One partial exception is an SMBus used to access
* "SPD" data for DRAM sticks. Those only use 24c02 EEPROMs.)
*
* So this driver uses "new style" I2C driver binding, expecting to be
* told what devices exist. That may be in arch/X/mach-Y/board-Z.c or
* similar kernel-resident tables; or, configuration data coming from
* a bootloader.
*
* Other than binding model, current differences from "eeprom" driver are
* that this one handles write access and isn't restricted to 24c02 devices.
* It also handles larger devices (32 kbit and up) with two-byte addresses,
* which won't work on pure SMBus systems.

/*
* I2C EEPROMs from most vendors are inexpensive and mostly interchangeable.
* Differences between different vendor product lines (like Atmel AT24C or
* MicroChip 24LC, etc) won't much matter for typical read/write access.
* There are also I2C RAM chips, likewise interchangeable. One example
* would be the PCF8570, which acts like a 24c02 EEPROM (256 bytes).
*
* However, misconfiguration can lose data. "Set 16-bit memory address"
* to a part with 8-bit addressing will overwrite data. Writing with too
* big a page size also loses data. And it's not safe to assume that the
* conventional addresses 0x50..0x57 only hold eeproms; a PCF8563 RTC
* uses 0x51, for just one example.
*
* Accordingly, explicit board-specific configuration data should be used
* in almost all cases. (One partial exception is an SMBus used to access
* "SPD" data for DRAM sticks. Those only use 24c02 EEPROMs.)
*
* So this driver uses "new style" I2C driver binding, expecting to be
* told what devices exist. That may be in arch/X/mach-Y/board-Z.c or
* similar kernel-resident tables; or, configuration data coming from
* a bootloader.
*
* Other than binding model, current differences from "eeprom" driver are
* that this one handles write access and isn't restricted to 24c02 devices.
* It also handles larger devices (32 kbit and up) with two-byte addresses,
* which won't work on pure SMBus systems.

* This module supports the PCA954x and PCA984x series of I2C multiplexer/switch
* chips made by NXP Semiconductors.
* This includes the:
* PCA9540, PCA9542, PCA9543, PCA9544, PCA9545, PCA9546, PCA9547,
* PCA9548, PCA9846, PCA9847, PCA9848 and PCA9849.
*
* These chips are all controlled via the I2C bus itself, and all have a
* single 8-bit register. The upstream "parent" bus fans out to two,
* four, or eight downstream busses or channels; which of these
* are selected is determined by the chip type and register contents. A
* mux can select only one sub-bus at a time; a switch can select any
* combination simultaneously.
