When the policy of the board is to select lowest voltage providing enough power, the current algorithm ignores the fact that the board input current limit might be lower than the charger maximum current for a particular voltage level leading to the possibility of selected a voltage with a lower available power. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BRANCH=none BUG=none TEST=set a Ryu board with the following configuration : PD_PREFER_LOW_VOLTAGE PD_MAX_POWER_MW 24000 PD_MAX_CURRENT_MA 1000 PD_MAX_VOLTAGE_MV 20000 connect it a Zinger (offering 3A @ 20V, 3A @ 12V and 3A @ 5V), see it selecting 20V rather 12V before the patch.
