Comment(by pgf):
thanks. i suspected as much. i'll look into that.
looking further ahead: this "resend" idea might not work out -- it seems
like a fragile undertaking. we should reconnect the keyboard to the EC --
i.e., populate both paths. the EC will hopefully never have use of that
line, but "just in case".
one possible scenario, mentioned above, which would avoid fully returning
to the old "EC fully in charge" ways: the EC would ignore KBDCLK except
when the system sleeps. during that time (SOC_SLEEP asserted), it would
respond to KBDCLK activity by immediately asserting KBDCLK itself, as flow
control. when ready, the SoC would instruct the EC to release the flow
control.
