Next version of patch for Kamil's patch:
[PATCH v6 4/8] dts: Add usb2phy to Exynos 5250
https://lkml.org/lkml/2014/1/29/302
Based on 'for-next' branch of Kgene's linux-samsung tree.
Tested with driver side patches:
[PATCH 0/2] usb: ehci/ohci-exynos: Move to generic phy framework
https://www.mail-archive.com/[email protected]/msg41246.html
Changes from v6:
- Splitted the patch into two:
adding syscon nodes to Exynos5250 and Exynos5420 in first;
and phy entry change in the second.
- Changed the name of phandle for usb2phy from 'usb2_phy_new'
to 'usb2_phy_gen' indicating generic phy.
- Using clock macros in dt entries.
