Subject: clk: uniphier: use devm_get_addr() to get base address
X-Git-Tag: v2016.05-rc1~114
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=45a3b1fd6ca524bebf5b9ce771ad1fb12f3514ce;p=u-boot

clk: uniphier: use devm_get_addr() to get base address

Currently, fdtdec_get_addr_size() does not support the address
translation, so it cannot handle device trees with non-straight
"ranges" properties.  (This would be a problem with DTS for UniPhier
ARMv8 SoCs.)
