Subject: [PATCH] mfd: syscon: support skip reset control for syscon devices
|
|
|
|
Some platform device drivers(e.g. ag71xx) expect exclusive reset
|
|
control. Fetching reset controller for syscon[1] will break these
|
|
drivers. This patch introduces a new property 'syscon-no-reset'
|
|
to skip it.
