Subject: clk: reverse default clk provider initialization order in of_clk_init()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3f6d439f202243a1594f2e1b86620af0d342bbe6;p=linux-beck.git

clk: reverse default clk provider initialization order in of_clk_init()

This restores the default clocks registration order as parsed from
devicetree, i.e. as before commit 1771b10d605d26ccee771a7fb4b08718
"clk: respect the clock dependencies in of_clk_init", for when there
is no explicit parent clock dependencies between clock providers
specified in the device tree.

It prevents regressions (boot failure, division by 0 errors) on
imx and exynos platforms.
