Subject: [PATCH v2 3/5] gpio: Change ISA_BUS_API dependency to selection
Date: Fri, 29 Dec 2017 15:13:46 -0500	[thread overview]
Message-ID: <1534276cb63d1e9e6dd139b4edceedbe728f65f5.1514578085.git.vilhelm.gray@gmail.com> (raw)
In-Reply-To: <cover.1514578085.git.vilhelm.gray@gmail.com>

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.
