+This causes the function to wrongly program some clock domains

+Subject: [PATCH 4/6] OMAP2+: PM: idle clkdms only if already in idle
+
+The omap_set_pwrdm_state function forces clockdomains
+to idle, without checking the existing idle state
+programmed, instead based solely on the HW capability
+of the clockdomain to support idle.
+This is wrong and the clockdomains should be idled
+post a state_switch *only* if idle transitions on the
+clockdomain were already enabled.
