Merge branch 'clk-ti' into clk-next
* clk-ti:
clk: ti: Prepare for remove of OF node name
clk: Clean up suspend/resume coding style
clk: ti: Add functions to save/restore clk context
clk: clk: Add clk_gate_restore_context function
clk: Add functions to save/restore clock context en-masse
clk: ti: dra7: add new clkctrl data
clk: ti: dra7xx: rename existing clkctrl data as compat data
clk: ti: am43xx: add new clkctrl data for am43xx
clk: ti: am43xx: rename existing clkctrl data as compat data
clk: ti: am33xx: add new clkctrl data for am33xx
clk: ti: am33xx: rename existing clkctrl data as compat data
clk: ti: clkctrl: replace dashes from clkdm name with underscore
clk: ti: clkctrl: support multiple clkctrl nodes under a cm node
dt-bindings: clock: dra7xx: add clkctrl indices for new data layout
dt-bindings: clock: am43xx: add clkctrl indices for new data layout
dt-bindings: clock: am33xx: add clkctrl indices for new data layout
