[PATCH v2] ARM: dts: dra7xx: Fix compatible string for PCF8575 chip

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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.

This is not a problem in practice because the I2C core uses
of_modalias_node() before matching drivers and this strips the
manufacturer name.

v2: Correct the claim that this is a practical problem.
