From 3d1a9b44b9dcd2c0f5d54c09596c96c0524d8340 Mon Sep 17 00:00:00 2001 From: Gregory Hermant Date: Tue, 13 Nov 2012 11:47:41 +0100 Subject: [PATCH] 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 Signed-off-by: Gregory Hermant --- 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 1bef2a0..532fb9e 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 { -- 1.7.9.5
