Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd:
"A few more clk driver fixes:
- Set the max_register member of the spreadtrum regmap so that reads
don't go off the end of the I/O space
- Avoid a clk parent error in the i.MX imx6ul driver when the
selector is unknown
- Fix an oops due to REGCACHE_NONE usage by the Renesas 9-series
driver"
