2011-07-07ARM: mxc: iomux-v1: Fix build warningFabio Estevam
Fix the following warning: CC arch/arm/plat-mxc/iomux-v1.o arch/arm/plat-mxc/iomux-v1.c: In function 'mxc_gpio_setup_multiple_pins': arch/arm/plat-mxc/iomux-v1.c:160: warning: 'ret' may be used uninitialized in this function arch/arm/plat-mxc/iomux-v1.c:160: note: 'ret' was declared here Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2011-07-07mxc: iomuxv1: Do not use gpio_request when setting the pin as GPIOFabio Estevam
When setting the IOMUX of multiple pins via mxc_gpio_setup_multiple_pins, gpio_request is called and this prevents subsequent calls of gpio_request done by drivers to succeed. Remove gpio_request call from mxc_gpio_setup_multiple_pins function. As gpio_request is removed from mxc_gpio_setup_multiple_pins, there is no need to have mxc_gpio_release_multiple_pins anymore, so remove this function. Tested on a mx27_3ds board and after applying this patch it is possible to define all the IOMUX setup in a static array Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2011-03-07ARM i.MX: iomux v1 initialization away from initcallSascha Hauer
This saves us from soc level dispatching in generic files Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2010-02-24arm/imx/iomux-v1: check for invalid modes in mxc_gpio_modeUwe Kleine-König
mxc_gpio_mode checks for invalid pins and so it returns zero for success, -EINVAL for invalid pins. While at it, remove definitions of GPIO_PORT_MAX removed as they are unused now. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
2010-02-24arm/imx/iomux-v1: rename header fileUwe Kleine-König
Addionally make iomux-mx*.h headers stand-alone and similar to iomux-v3 platform files should include their platform iomux header from now on. For now iomux.h simply includes all iomux-v1 platform headers and so provides compatibility until all files are converted. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
2010-02-24arm/imx/iomux-v1: make base address a runtime choiceUwe Kleine-König
While at it move register modification to static inlines and so make the relevant code more readable. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
