The binding definition for the PCF857x GPIO expanders doesn't mention a "ti,pcf8575" compatible string. This is apparently because TI is only a second source - there is no functional difference between PCF8575 chips manufactured by TI and NXP, and the same board might be populated with either depending on availability.
As a practical matter, the gpio-pcf857x driver doesn't match this string, so this device tree currently won't work.
