Subject: [PATCH 05/19] powerpc: dts: mpc8315e: Disable peripherals by
default
From: "J. Neuschäfer" <j.ne@...teo.net>
Peripherals with a connection to the outside of the chip aren't
necessarily used on all board designs, so disable them by default,
and enable them per-board.
Signed-off-by: J. Neuschäfer <j.ne@...teo.net>
