From: Suman Anna Date: Fri, 4 Mar 2016 16:36:39 +0000 (-0600) Subject: ARM: keystone2: K2G: power-off DSP during boot X-Git-Tag: v2016.05-rc1~442 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f2a8279e7647411cfdd694daec7903d60da5a36f;p=u-boot ARM: keystone2: K2G: power-off DSP during boot The DSPs are powered on by default upon a Power ON reset, and they are powered off on current Keystone 2 SoCs - K2HK, K2L, K2E during the boot in u-boot. This is not functional on K2G though. Extend the existing DSP power-off support to the only DSP present on K2G. Do note that the PSC clock domain module id for DSP on K2G differs from that of previous Keystone2 SoCs.
