Signed-off-by: sricharan --- V1: Initial patch V2: Remove flags that were to be used for only testing. V3: Correct the off mode settings. V4: Use the Macro to mux the static pads. arch/arm/mach-omap2/board-3430sdp.c | 102 ++++++++++++++++++++++++++++++++++- 1 files changed, 101 insertions(+), 1 deletions(-) diff --git a/arch/arm/mach-omap2/board-3430sdp.c b/arch/arm/mach-omap2/board-3430sdp.c index 5464bec..b391804 100644 --- a/arch/arm/mach-omap2/board-3430sdp.c +++ b/arch/arm/mach-omap2/board-3430sdp.c @@ -652,6 +652,106 @@ static const struct ehci_hcd_omap_platform_data ehci_pdata __initconst = { static struct omap_board_mux board_mux[] __initdata = { { .reg_offset = OMAP_MUX_TERMINATOR }, }; + +static struct omap_device_pad serial1_pads[] __initdata = { + /* + * Note that off output enable is an active low + * signal.
