Name:   sx150x

Info:   Configures the Semtech SX150X I2C GPIO expanders.

Load:   dtoverlay=sx150x,<param>=<val>

Params: sx150<x>-<n>-<m>        Enables SX150X device on I2C#<n> with slave

                                address <m>. <x> may be 1-9. <n> may be 0 or 1.

                                Permissible values of <m> (which is denoted in

                                hex) depend on the device variant. For SX1501,

                                SX1502, SX1504 and SX1505, <m> may be 20 or 21.

                                For SX1503 and SX1506, <m> may be 20. For

                                SX1507 and SX1509, <m> may be 3E, 3F, 70 or 71.

                                For SX1508, <m> may be 20, 21, 22 or 23.



        sx150<x>-<n>-<m>-int-gpio

                                I2C#<n> with slave address <m>, specifies

                                the GPIO pin to which NINT output of SX150X is

                                connected.
