From 280df6b3c3ad777a91f1011cd98d50df891bfef8 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Fri, 20 May 2011 00:40:19 -0600 Subject: basic_mmio_gpio: split into a gpio library and platform device Allow GPIO_BASIC_MMIO_CORE to be used to provide an accessor library for implementing GPIO drivers whilst abstracting the register access detail. Based on a patch from Anton Vorontsov[1] and adapted to allow bgpio_chip to be embedded in another structure. Changes since v1: - Register the gpio_chip in the platform device probe 1. https://lkml.org/lkml/2011/4/19/401 Signed-off-by: Anton Vorontsov Signed-off-by: Jamie Iles Signed-off-by: Grant Likely --- drivers/gpio/Kconfig | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'drivers/gpio/Kconfig') diff --git a/drivers/gpio/Kconfig b/drivers/gpio/Kconfig index 44235bd4f9d..b57ec09af89 100644 --- a/drivers/gpio/Kconfig +++ b/drivers/gpio/Kconfig @@ -70,8 +70,14 @@ config GPIO_MAX730X comment "Memory mapped GPIO drivers:" +config GPIO_BASIC_MMIO_CORE + tristate + help + Provides core functionality for basic memory-mapped GPIO controllers. + config GPIO_BASIC_MMIO tristate "Basic memory-mapped GPIO controllers support" + select GPIO_BASIC_MMIO_CORE help Say yes here to support basic memory-mapped GPIO controllers. -- cgit v1.2.3-18-g5258
