From 93de83a21e76eda25517562a9e62f7b6a6f38126 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 21 Mar 2019 11:00:21 -0700 Subject: [PATCH] bus: ti-sysc: Manage clocks for the interconnect target module in all cases We are currently not managing interconnect target module clocks in the for legacy platform data based case. This causes a problem for using the platform data based functions when dropping the platform data for the interconnect target module configuration. To avoid a situation where we need to populate the main and optional clocks also for the platform data based functions, let's just manage the clocks directly in ti-sysc driver. This means that until the interconnect target module confugration platform data is dropped our use count for clk_enable() will be 2 instead of 1.
