[PATCH 2/2] powerpc: wii.dts: Add GPIO keys

Sun Jan 13 03:21:24 AEDT 2019


The Wii has POWER and EJECT buttons, which are connected through
normalization logic to the GPIO controller (the length of an assertion
of these signals is always the same, regardless of how long the user
pressed the buttons).
