cp2112_i2c_xfer() only supports a single i2c_msg and only
reads up to 61 bytes. More than one message at a time
and longers reads just return errors.
This is a serious limitation. For example, the at24 eeprom driver
generates paired write and read messages (for eeprom address and data).

Please submit this as a completely new series, obsoleting the previous
patch.

I've separated out the cp2112_i2c_xfer() bug fix from the patch. Should
I submit it as v2 or a new patch altogether?
Thanks.

That's true, but instead of returning short, the old

According to I2C spec, max SCL rate is 100 kHz, but SCx200/CS5536
controller is currently driving it at 214 kHz according to my math.
SCL is derived from an input clock of 48 MHz, which must be divided
by 480 (240 cycles for each SCL high/low state) to be within spec.

This is a proxy I2C driver for APM X-Gene SoC. It uses the mailbox driver
to tunnel i2c transactions via the SLIMpro processor.
V3 Change:
- Add ACPI support
- Fix previous comments.

The driver uses pinctrl directly and thus should include the appropriate
header. Sort the headers while we are here to have a better view what is
included and what is not.

Those symlinks are created for the mux_dev, so we need to remove it from
there. Currently, it breaks for muxes where the mux_dev is not the device
of the parent adapter like this:
