Subject: ARM: davinci: dm365: add new clock init using common clock framework
X-Git-Tag: v4.19~317^2~14^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=21c2f4773dd0c45899a524a4a7f70dd32db4c1a1;p=platform%2Fkernel%2Flinux-rpi.git

ARM: davinci: dm365: add new clock init using common clock framework

This adds the new board-specific clock init in mach-davinci/dm365.c
using the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

Also clean up the #includes since we are adding some here.
