Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd:
- build fix to export the clk_bulk_prepare() symbol
- suspend fix for Samsung Exynos SoCs where we need to keep clks on
across suspend
- two critical clk markings for clks that shouldn't ever turn off on
Rockchip SoCs
- a fix for a copy-paste mistake on Rockchip rk3128 causing some clks
to touch the same bit and trample over one another
* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
clk: samsung: exynos4: Enable VPLL and EPLL clocks for suspend/resume cycle

clk: rockchip: add sclk_timer5 as critical clock on rk3128
clk: rockchip: fix up rk3128 pvtm and mipi_24m gate regs error
clk: rockchip: add pclk_pmu as critical clock on rk3128
