Then use phandle-array syntax - see examples. Explain in description the purpose of this register in the context of *this* device. Best regards, Krzysztof

Then use phandle-array syntax - see examples. No this is not one register only. PA_STATS is a set of registers. My bad I should have mentioned *registers* in the commit description. Just like MII_RT and MII_G_RT modules, PA_STATS is also a set of registers where different statistics are dumped by ICSSG firmware. Moduling this as syscon will help the driver read/write those statistics using regmap_read() / write() just like the driver currently read / write registers from mii_rt and mii_g_rt regmaps. I have tried to describe this node *ti,pa-stats* the same way as "ti,mii-g-rt" and "ti,mii-rt" > Explain in description the purpose of this register in the context of > *this* device. > Sure will do that. > Best regards, > Krzysztof >

Add documentation for ti,pa-stats property which is syscon regmap for PA_STATS register. This will be used to dump statistics maintained by ICSSG firmware.
