Subject: [PATCH] ARM: OMAP: hwmod: AM33xx/43xx: Add HWMOD_INIT_NO_IDLE flag to tptc

In Linux we do not have driver for TPTCs of eDMA3 since there is no need to
do any configuration within TPTC for the eDMA3 to be operational. All
configuration is via the TPCC.
To prevent the omap_device_late_idle() to disable the TPTCs when they are
no longer bind with the edma driver, the HWMOD_INIT_NO_IDLE need to be
added.

Vinod, Olof,

This patch somehow got lost in my working branch. It was mixed within the patches
I will have for 4.5 while it should have been within the new eDMA3 binding
series..

Regards,
Peter
