Subject: [PATCH 031/149] OMAP2+: hwmod: Enable module in shutdown to access sysconfig
|
|
|
|
When calling the shutdown, the module may be already in idle.
|
|
Accessing the sysconfig register will then lead to a crash.
|
|
In that case, re-enable the module in order to allow the access
|
|
to the sysconfig register.
