Multiple Intel platforms started using similar GPIO controllers. There was a need to develop a common library driver. Intel Tangier implements the common GPIO functionalities for Elkhart Lake and Merrifield platforms. This patch set introduces: 1. Intel Tangier driver that supports the common GPIO functionalities for Elkhart Lake and Merrifield platforms. 2. Intel Tangier adaptation for Merrifield GPIO driver. 3. GPIO driver for Elkhart Lake PSE GPIO IP.
