| Subject: [PATCH] net: mscc: ocelot: move resource ioremap and regmap init to
 | |
|  common code
 | |
| 
 | |
| Let's make this ioremap and regmap init code common.  It should not
 | |
| be platform dependent as it should be usable by PCI devices too.
 | |
| Use better names where necessary to avoid clashes.
