From e4997a631e129df3d171da16de9504810891744c Mon Sep 17 00:00:00 2001 From: Caveh Jalali Date: Thu, 24 Aug 2017 15:40:58 -0700 Subject: anx3429: read chip firmware version during init fetching the chip firmware version toward the end of the chip anx74xx_tcpm_init() sequence is a good place to do this. we need this info in any case and this is a safe place to access device registers and cache the values. subsequent chip firmware queries typically return the cached value. also, tcpci_tcpm_init() is already structured this way. TEST=verified with follow-up CL that firmware update succeeds and new version is reported BRANCH=none BUG=b:35586895 Change-Id: Ic3fd07bbf8a220bfd506d59d8a1f3ea25b14e94c Signed-off-by: Caveh Jalali Reviewed-on: https://chromium-review.googlesource.com/634513 Reviewed-by: Shawn N --- driver/tcpm/anx74xx.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'driver/tcpm') diff --git a/driver/tcpm/anx74xx.c b/driver/tcpm/anx74xx.c index 74de3ba6b0..e2c1081ceb 100644 --- a/driver/tcpm/anx74xx.c +++ b/driver/tcpm/anx74xx.c @@ -1057,6 +1057,8 @@ static int anx74xx_tcpm_init(int port) if (rv) return EC_ERROR_UNKNOWN; + tcpm_get_chip_info(port, 1, NULL); + return EC_SUCCESS; } -- cgit v1.2.1
