From 46de3adb5240f33b6dbf89ca0dc4ba5c86abebb1 Mon Sep 17 00:00:00 2001 From: Eddie James Date: Mon, 3 Aug 2020 09:50:55 -0500 Subject: leds: pca955x: Add an IBM software implementation of the PCA9552 chip IBM created an implementation of the PCA9552 on a PIC16F microcontroller. The I2C device addresses are different from the hardware PCA9552, so add a new compatible string and associated platform data to be able to probe this device.
