From 57f57201360e443e7ec36124861a2e025d3d39ba Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 19 Nov 2020 14:24:29 +0200 Subject: [PATCH] clk: ti: dra7: Drop idlest polling from IVA clkctrl clocks Similar to what we've done for IPU and DSP let's ignore the status bit for the IVA clkctrl register. The clkctrl status won't change unless the related rstctrl is deasserted, and the rstctrl status won't change unless the clkctrl is enabled.
