From: Haavard Skinnemoen Date: Fri, 2 May 2008 13:21:40 +0000 (+0200) Subject: avr32: Rename pm_init() as clk_init() and make SoC-specific X-Git-Tag: v1.3.4-rc1~114^2~23^2~8 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=3ace2527ba80bd2fe1bceaab50d0b3c4fb5dd020;p=u-boot avr32: Rename pm_init() as clk_init() and make SoC-specific pm_init() was always more about clock initialization than anything else. Dealing with PLLs, clock gating and such is also inherently SoC-specific, so move it into a SoC-specific directory.
