The platform was deprecated in commit 6a5e69c7ddea ("ARM: s3c: mark
as deprecated and schedule removal") and can be removed. This includes
all files that are exclusively for s3c24xx and not shared with s3c64xx,
as well as the glue logic in Kconfig and the maintainer file entries.

Samsung GPIO implementation
|
|
===========================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This outlines the Samsung GPIO implementation and the architecture
|
|
specific calls provided alongside the drivers/gpio core.
|
|
|
|
|
|
GPIOLIB integration
|
|
-------------------
|
|
|
|
The gpio implementation uses gpiolib as much as possible, only providing
|
|
specific calls for the items that require Samsung specific handling, such
|
|
as pin special-function or pull resistor control.
|
|
|
|
GPIO numbering is synchronised between the Samsung and gpiolib system.
|
|
|
|
|
|
PIN configuration
|
|
-----------------
|
|
|
|
Pin configuration is specific to the Samsung architecture, with each SoC
|
|
registering the necessary information for the core gpio configuration
|
|
implementation to configure pins as necessary.
|
|
|
|
The s3c_gpio_cfgpin() and s3c_gpio_setpull() provide the means for a
|
|
driver or machine to change gpio configuration.
|
|
|
|
See arch/arm/mach-s3c/gpio-cfg.h for more information on these functions.
