From f1408f95e92772efca79dbdbc26d802a459831d9 Mon Sep 17 00:00:00 2001 From: "ramesh.chandrasekaran" Date: Mon, 1 Oct 2012 09:50:34 +0530 Subject: trace-debug[stm]: Fix for BT/WLAN instability Pins under mop500_ske_pins array are used for different functionalities in snowball. Ex: GPIO161 pin configured for keypad here must stay configured as GPIO alternate function for operating PMU_EN pin of BT/WLAN chip in snowball. So forbid configuring these pins, for snowball Signed-off-by: Rajanikanth H.V --- arch/arm/mach-ux500/board-mop500-stm.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/arch/arm/mach-ux500/board-mop500-stm.c b/arch/arm/mach-ux500/board-mop500-stm.c index 1bef2a01873..532fb9efcfa 100644 --- a/arch/arm/mach-ux500/board-mop500-stm.c +++ b/arch/arm/mach-ux500/board-mop500-stm.c @@ -121,7 +121,9 @@ static int stm_ste_disable_ape_on_mipi60(void) if (retval) STM_ERR("Failed to disable MIPI60\n"); else { - retval = nmk_config_pins(ARRAY_AND_SIZE(mop500_ske_pins)); + if (!machine_is_snowball()) + retval = nmk_config_pins( + ARRAY_AND_SIZE(mop500_ske_pins)); if (retval) STM_ERR("Failed to enable SKE gpio\n"); } @@ -314,7 +316,8 @@ static int stm_ste_connection(enum stm_connection_type con_type) /* Enable altC3 on GPIO70-74 (STMMOD) and GPIO75-76 (UARTMOD) */ prcmu_enable_stm_mod_uart(); /* Enable APE on MIPI60 */ - retval = nmk_config_pins_sleep(ARRAY_AND_SIZE(mop500_ske_pins)); + if (!machine_is_snowball()) + retval = nmk_config_pins_sleep(ARRAY_AND_SIZE(mop500_ske_pins)); if (retval) STM_ERR("Failed to disable SKE GPIO\n"); else { -- cgit v1.2.3
