From 120d54402d03944f32230ccfbb943a6707a16676 Mon Sep 17 00:00:00 2001 From: Tom Hughes Date: Fri, 26 Feb 2021 15:00:42 -0800 Subject: docs/fingerprint: Update power numbers for dartmonkey https://crrev.com/c/2689101 is needed in order to configure the sleep GPIOs correctly on icetower, so the change was cherry-picked to the release branch to perform the measurement.
