Subject: platform: zynqmp: Map missing clocks to respective node
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e940636f0807a23107bf6e1e115a4c8c24e25df5;p=people%2Fsstabellini%2Fxen-unstable.git%2F.git

platform: zynqmp: Map missing clocks to respective node

Dom0 requires access of AMS_REF, TOPSW_LSBUS and LPD_LSBUS clock.
Map these clocks to respective node to provide access
if Dom0 has permission to access to those nodes.
