Hi Enric, On 2017년 12월 06일 20:10, Enric Balletbo i Serra wrote: > From: Benson Leung <bleung@chromium.org> > > Extend the driver to notify host and device type cables and the presence > of power. > > Signed-off-by: Benson Leung <bleung@chromium.org> > Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> > --- > drivers/extcon/extcon-usbc-cros-ec.c | 142 ++++++++++++++++++++++++++++++++++- > include/linux/mfd/cros_ec_commands.h | 17 +++++ > 2 files changed, 155 insertions(+), 4 deletions(-) Looks good to me. After you uses the BIT() macro as the Lee's comment on v2, I'll merge this patch.
