X-Git-Tag: v4.10-rc1~161^2~29^2~8
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=30ad3cf00e94f4a77775d851de15549099f0224e;p=uclinux-h8%2Flinux.git

clk: renesas: rcar-gen3-cpg: Always use readl()/writel()

The R-Car Gen3 CPG/MSSR driver uses a mix of clk_readl()/clk_writel()
and readl()/writel() to access the clock registers. Settle on the
generic readl()/writel().
