From 35decc803c8ad9a84de890c1fea0ba1768666390 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Fri, 29 Dec 2017 15:13:46 -0500 Subject: [PATCH] gpio: Change ISA_BUS_API dependency to selection The ISA_BUS_API Kconfig option enables the compilation of the ISA bus driver. The ISA bus driver does not perform any hardware interaction, and is instead just a thin layer of software abstraction to eliminate boilerplate code common to ISA-style device drivers. Since ISA_BUS_API has no dependencies and does not jeopardize the integrity of the system when enabled, drivers should select it when the ISA bus driver functionality is needed.
