Merge branch 'clk-ti' into clk-next

* clk-ti: clk: Remove CLK_IS_BASIC clk flag clk: ti: dra7: disable the RNG and TIMER12 clkctrl clocks on HS devices clk: ti: dra7x: prevent non-existing clkctrl clocks from registering ARM: omap2+: hwmod: drop CLK_IS_BASIC flag usage clk: ti: export the omap2_clk_is_hw_omap call
