From f8251f1dfda9e1200545bf19270d9df2273bdfa1 Mon Sep 17 00:00:00 2001 From: Phil Reid Date: Wed, 25 Jan 2017 09:31:06 +0800 Subject: i2c: mux: pca954x: Add missing pca9542 definition to chip_desc The spec for the pca954x was missing. This chip is the same as the pca9540 except that it has interrupt lines. While the i2c_device_id table mapped the pca9542 to the pca9540 definition the compatible table did not. In preparation for irq support add the pca9542 definition.
