* host_command: Change host command return value to enum ec_statusTom Hughes2019-10-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the host command handler callback function returns an int, it's easy to accidentally mix up the enum ec_error_list and enum ec_status types. The host commands always expect an enum ec_status type, so we change the return value to be of that explicit type. Compilation will then fail if you accidentally try to return an enum ec_error_list value. Ran the following commands and then manually fixed up a few remaining instances that were not caught: git grep --name-only 'static int .*(struct host_cmd_handler_args \*args)' |\ xargs sed -i 's#static int \(.*\)(struct host_cmd_handler_args \*args)#\ static enum ec_status \1(struct host_cmd_handler_args \*args)##' git grep --name-only 'int .*(struct host_cmd_handler_args \*args)' |\ xargs sed -i 's#int \(.*\)(struct host_cmd_handler_args \*args)#\ enum ec_status \1(struct host_cmd_handler_args \*args)##' BRANCH=none BUG=chromium:1004831 TEST=make buildall -j Cq-Depend: chrome-internal:1872675 Change-Id: Id93df9387ac53d016a1594dba86c6642babbfd1e Signed-off-by: Tom Hughes <tomhughes@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1816865 Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org> Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>
* common: Add uptime host commandTom Hughes2019-09-031-0/+41
This moves the EC_CMD_GET_UPTIME_INFO command from behind the CONFIG_CMD_AP_RESET_LOG config in chipset.c into the generic common/uptime.c file, so that all boards in the codebase can use it. If CONFIG_CMD_AP_RESET_LOG is enabled, the "AP reset stats" will be filled. Otherwise, ap_reset_stats is a no-op and recent_ap_reset is filled with zero.
