ARM: dts: dra7xx-clocks: Fixup IPU1 mux clock parent source
The IPU1 functional clock is the output of a mux clock (represented by ipu1_gfclk_mux previously) and the clock source for this has been updated to be sourced from dpll_core_h22x2_ck in commit 39879c7d963e ("ARM: dts: dra7xx-clocks: Source IPU1 functional clock from CORE DPLL"). ipu1_gfclk_mux is an obsolete clock now with the clkctrl conversion, and this clock source parenting is lost during the new clkctrl layout conversion. Remove this stale clock and fix up the clock source for this mux clock using the latest equivalent clkctrl clock. This restores the previous logic and ensures that the IPU1 continues to run at the same frequency of IPU2 and independent of the ABE DPLL. Fixes: b5f8ffbb6fad ("ARM: dts: dra7: convert to use new clkctrl layout") Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
