From 4d0030bdb47b703bebe4796d5c16beb776c6950f Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 12 Sep 2019 16:26:13 +0300 Subject: clk: ti: am33xx: drop idlest polling from pruss clkctrl clock The PRUSS module on AM33xx SoCs has a hardreset line and is controlled by a PRCM reset line. Any clkctrl enable/disable operations cannot be checked for module enabled/disabled status independent of the reset operation, and this causes some unwanted timeouts in the kernel and unbalanced states for the PRUSS clocks. These details should be handled by the driver integration code itself. Add the CLKF_NO_IDLEST flag to the PRUSS clkctrl clock so that these module status checks are skipped.
