From 4f4322dd68575402e099e2dfda057687388f064e Mon Sep 17 00:00:00 2001 From: Nathaniel Roach Date: Sat, 10 Nov 2018 08:34:44 +0800 Subject: lenovo/h8,thinkpads: Re-do USB Always On Re-write the UAO handling code as it had stopped working (#171) (the flag was not getting read from the RTC properly in SMM) Remove the SMM code as it's not needed (but EC flag won't be set upon entering S3 now) Set the EC flags on boot the same way other flags are set Document bitwise operators for clarity Propagate changes to other Thinkpads (updated X201 to have 2 bits for the flag as it only had 1) Per Nicola Corna's previous commits, 0x0d is set for "AC only" "AC only" does exhibit different behaviour - the USB port is turned on a few seconds after entering S3, rather than < 1 sec, regardless of AC status Tested on X220 Change-Id: If812cd1ef8fb1a24d7fadbe834f574b40cbcd56a Signed-off-by: Nathaniel Roach Reviewed-on: https://review.coreboot.org/c/29565 Tested-by: build bot (Jenkins) Reviewed-by: Philipp Deppenwiese --- src/mainboard/lenovo/l520/smihandler.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'src/mainboard/lenovo/l520') diff --git a/src/mainboard/lenovo/l520/smihandler.c b/src/mainboard/lenovo/l520/smihandler.c index fa038ed92b..982233d4bc 100644 --- a/src/mainboard/lenovo/l520/smihandler.c +++ b/src/mainboard/lenovo/l520/smihandler.c @@ -73,8 +73,6 @@ int mainboard_smi_apmc(u8 data) void mainboard_smi_sleep(u8 slp_typ) { - h8_usb_always_on(); - if (slp_typ == 3) { u8 ec_wake = ec_read(0x32); /* If EC wake events are enabled, enable wake on EC WAKE GPE. */ -- cgit v1.2.3
