As a result on Apalis iMX8 USB HSIC comes up in a +state were it does not recognize our USB3503 hub correctly. + +Refer to the SCFW doc file sc_fw_port.pdf for more info on the various +sc_reboot*, sc_reset* functionalities. + +Upstream-Status: Inappropriate [configuration] + +Related-to: ELB-2702 +Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> +--- + plat/imx/common/imx8_psci.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/plat/imx/common/imx8_psci.c b/plat/imx/common/imx8_psci.c +index bf0b2f6b1..310f81c2e 100644 +--- a/plat/imx/common/imx8_psci.c ++++ b/plat/imx/common/imx8_psci.c +@@ -21,7 +21,7 @@ void __dead2 imx_system_off(void) + + void __dead2 imx_system_reset(void) + { +- sc_pm_reboot(ipc_handle, SC_PM_RESET_TYPE_COLD); ++ sc_pm_reset(ipc_handle, SC_PM_RESET_TYPE_BOARD); + wfi(); + ERROR("system reset failed.\n"); + panic(); +-- +2.20.1 + |
