From 17689367d5ed24f20145f8a68414d34da039bb79 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Tue, 24 Nov 2020 10:33:00 -0700 Subject: mb/google/volteer: Make use of fw_config_is_provisioned() In cases when a volteer device is unprovisioned, the safest thing to do for GPIOs that will normally be used for audio codec buses is to leave them disabled (configured as PAD_CFG_NC). This patch adds support for that. BUG=none TEST=add debug print to new if branch; remove fw_config from CBI and see print on console Change-Id: I8efd101174f6e3d7233d2bf803b680673cada81a Signed-off-by: Tim Wawrzynczak Reviewed-on: https://review.coreboot.org/c/coreboot/+/47972 Reviewed-by: Furquan Shaikh Reviewed-by: Nick Vaccaro Reviewed-by: Duncan Laurie Tested-by: build bot (Jenkins) --- src/mainboard/google/volteer/fw_config.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/mainboard/google') diff --git a/src/mainboard/google/volteer/fw_config.c b/src/mainboard/google/volteer/fw_config.c index c444b4c15a..1025119658 100644 --- a/src/mainboard/google/volteer/fw_config.c +++ b/src/mainboard/google/volteer/fw_config.c @@ -72,6 +72,13 @@ static const struct pad_config sd_power_enable_pads[] = { static void fw_config_handle(void *unused) { + if (!fw_config_is_provisioned()) { + gpio_configure_pads(i2s_disable_pads, ARRAY_SIZE(i2s_disable_pads)); + gpio_configure_pads(dmic_disable_pads, ARRAY_SIZE(dmic_disable_pads)); + gpio_configure_pads(sndw_disable_pads, ARRAY_SIZE(sndw_disable_pads)); + return; + } + if (fw_config_probe(FW_CONFIG(AUDIO, NONE))) { printk(BIOS_INFO, "Configure GPIOs for no audio.\n"); gpio_configure_pads(i2s_disable_pads, ARRAY_SIZE(i2s_disable_pads)); -- cgit v1.2.3
