[PATCH v6 3/4] spi: bcm2835: add the auxiliary spi1 and spi2 to the device tree

kernel at martin.sperl.org kernel at martin.sperl.org
Fri Sep 11 04:22:05 PDT 2015


From: Martin Sperl <kernel at martin.sperl.org>

This enables the use of the auxiliary spi1 and spi2 devices
on the bcm2835 SOC.

Note that this requires the use of the new clk-bcm2835-aux to work.

Signed-off-by: Martin Sperl <kernel at martin.sperl.org>
