The issue was reported on a am33xx device and was not seen on omap4 or omap5 devices as the hwmod data for both omap4 and omap5 had statically defined
HWMOD_INIT_NO_IDLEandHWMOD_INIT_NO_RESETfor uart3 which happens to be the debug console used on omap4 panda and omap5 uevm boards.The serial driver should be capable of setting this on it's own as it sets up the console.
These flags are used to avoid an early reset that hwmod does to all devices on the SoC and is done much before serial driver is initialized.
