That'll be these 3 branches then:

otg-for-v3.9 (bugfix for v3.9):
6bef020 USB otg: use try_module_get in all usb_get_phy functions and add missing module_put

otg-for-v3.10 (depends on otg-for-v3.9):
a0e17f5 USB: move bulk of otg/otg.c to phy/phy.c
a6fc0d1 USB: add devicetree helpers for determining dr_mode and phy_type
8a4c9f8 USB mxs-phy: Register phy with framework

chipidea-for-v3.10 (most patches depend on otg-for-v3.10):
15c930e USB chipidea: ci13xxx-imx: create dynamic platformdata
9466e85 USB chipidea: add PTW and PTS handling
ad2cc0d USB chipidea: introduce dual role mode pdata flags
8e7f1bb USB chipidea i.MX: introduce dr_mode property
5d83722 USB chipidea i.MX: use devm_usb_get_phy_by_phandle to get phy
