[PATCH v4 2/4] ARM: at91/dt: define sam9x5 clocks
Boris BREZILLON

Tue May 13 07:51:24 PDT 2014
Define sam9x5 clocks in sam9x5 dt files and make use of them in peripheral
definitions.

Hello,
Sorry for the noise, I modified the wrong compatible property (main_clk
instead of main_osc_clk).
This version revert the modification introduced in v3 and fix the
main_osc_clk compatible property.
Best Regards,
Boris
Changes since v3:
- revert v2 fix and fix main osc clk compatible string
Changes since v2:
- fix main clk compatible string
