Subject: PCF857x and 16-bit GPIO expanders

Hi,

has anyone ever successfully using gpio-pcf857x.c driver with 16-bit
gpio expanders ? We're having some issues here where toggling the last
gpio pin (gpio 15) on a PCF8575 device causes platform to hang and I
can't come up with any explanation of why would it hang...

Any hints ?

cheers
