Without it, all LEDs turn off during S3. + +Change-Id: Ic0d887f75be13c3fb9f6df62153ac458895e0283 +Signed-off-by: Nicholas Chin <nic.c3.14@gmail.com> +--- + src/mainboard/dell/e7240/smihandler.c | 9 +++++++++ + src/mainboard/dell/gm45_latitude/smihandler.c | 9 +++++++++ + src/mainboard/dell/snb_ivb_latitude/smihandler.c | 9 +++++++++ + 3 files changed, 27 insertions(+) + create mode 100644 src/mainboard/dell/e7240/smihandler.c + create mode 100644 src/mainboard/dell/gm45_latitude/smihandler.c + create mode 100644 src/mainboard/dell/snb_ivb_latitude/smihandler.c + +diff --git a/src/mainboard/dell/e7240/smihandler.c b/src/mainboard/dell/e7240/smihandler.c +new file mode 100644 +index 0000000000..00e55b51db +--- /dev/null ++++ b/src/mainboard/dell/e7240/smihandler.c +@@ -0,0 +1,9 @@ ++/* SPDX-License-Identifier: GPL-2.0-only */ ++ ++#include <cpu/x86/smm.h> ++#include <ec/dell/mec5035/mec5035.h> ++ ++void mainboard_smi_sleep(u8 slp_typ) ++{ ++ mec5035_smi_sleep(slp_typ); ++} +diff --git a/src/mainboard/dell/gm45_latitude/smihandler.c b/src/mainboard/dell/gm45_latitude/smihandler.c +new file mode 100644 +index 0000000000..00e55b51db +--- /dev/null ++++ b/src/mainboard/dell/gm45_latitude/smihandler.c +@@ -0,0 +1,9 @@ ++/* SPDX-License-Identifier: GPL-2.0-only */ ++ ++#include <cpu/x86/smm.h> ++#include <ec/dell/mec5035/mec5035.h> ++ ++void mainboard_smi_sleep(u8 slp_typ) ++{ ++ mec5035_smi_sleep(slp_typ); ++} +diff --git a/src/mainboard/dell/snb_ivb_latitude/smihandler.c b/src/mainboard/dell/snb_ivb_latitude/smihandler.c +new file mode 100644 +index 0000000000..00e55b51db +--- /dev/null ++++ b/src/mainboard/dell/snb_ivb_latitude/smihandler.c +@@ -0,0 +1,9 @@ ++/* SPDX-License-Identifier: GPL-2.0-only */ ++ ++#include <cpu/x86/smm.h> ++#include <ec/dell/mec5035/mec5035.h> ++ ++void mainboard_smi_sleep(u8 slp_typ) ++{ ++ mec5035_smi_sleep(slp_typ); ++} +-- +2.39.5 + |
