-Subject: [PATCH] clk: bcm2835: Add a driver for the auxiliary peripheral clock
- gates.
-
-There are a pair of SPI masters and a mini UART that were last minute
-additions. As a result, they didn't get integrated in the same way as
-the other gates off of the VPU clock in CPRMAN.

-updated Makefile to preserve the rasoberry pi architectures
