From 940dd96fe9dec5b6ba4bb7ebc33212ff66db243c Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 11 Oct 2011 16:16:12 -0600 Subject: [PATCH] arm/tegra: Prep boards for gpio/pinmux conversion to pdevs The Tegra GPIO driver will be converted from static registration via postcore_initcall() to be a platform device later in this patch series. A new Tegra pinmux platform device will also be added. Prepare for this by modifying all boards to register the appropriate platform devices before-hand, so that when the drivers are converted, those devices will be probed, and git bisectability will be maintained. v2: Add resource definitions for GPIO and pinmux Signed-off-by: Stephen Warren Signed-off-by: Olof Johansson --- arch/arm/mach-tegra/board-harmony-pinmux.c | 8 ++ arch/arm/mach-tegra/board-paz00-pinmux.c | 8 ++ arch/arm/mach-tegra/board-seaboard-pinmux.c | 9 ++- arch/arm/mach-tegra/board-trimslice-pinmux.c | 7 ++ arch/arm/mach-tegra/devices.c | 84 ++++++++++++++++++++ arch/arm/mach-tegra/devices.h | 2 + 6 files changed, 116 insertions(+), 2 deletions(-) diff --git a/arch/arm/mach-tegra/board-harmony-pinmux.c b/arch/arm/mach-tegra/board-harmony-pinmux.c index 4d63e2e97a8d..e99b45618cd0 100644 --- a/arch/arm/mach-tegra/board-harmony-pinmux.c +++ b/arch/arm/mach-tegra/board-harmony-pinmux.c @@ -20,6 +20,7 @@ #include "gpio-names.h" #include "board-harmony.h" +#include "devices.h" static struct tegra_pingroup_config harmony_pinmux[] = { {TEGRA_PINGROUP_ATA, TEGRA_MUX_IDE, TEGRA_PUPD_NORMAL, TEGRA_TRI_NORMAL}, @@ -140,6 +141,11 @@ static struct tegra_pingroup_config harmony_pinmux[] = { {TEGRA_PINGROUP_XM2D, TEGRA_MUX_NONE, TEGRA_PUPD_NORMAL, TEGRA_TRI_NORMAL}, };
