From 6a6f9e73dd65f9201bee911d2fae8595f86c093b Mon Sep 17 00:00:00 2001 From: Mauri Sandberg Date: Thu, 21 May 2020 09:59:52 +0300 Subject: packages: kernel: add gpio-nxp-74hc153 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit NXP 74HC153 is a GPIO expander. Its original source cide sits in ar71xx architecture tree. It has been slightly modified to get GPIO pin configuration from the device tree rather than a MACH file. Changes to the source file: - Remove struct nxp_74hc153_config - in nxp_74hc153_probe(), fetch GPIO configuration from device tree - allow GPIO framework decide the base number by passing -1 to it - remove support for kernel versions below 4.5.0 - add OF device compatibility string Create a package for inclusion in image.
