[PATCH 2/2] ARM: OMAP2+: Add dm816x hwmod support
Tony Lindgren

Tue Jan 13 15:22:35 PST 2015
Add minimal hwmod support that works at least on dm8168. This
is based on the code in the earlier TI CDP tree, and an earlier
patch by Aida Mynzhasova <aida.mynzhasova at skitlab.ru>.
I've set up things to work pretty much the same way as for
am33xx. We are basically using cm33xx.c with a different set
of clocks and clockdomains.
This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches
