Merge tag 'phy-for-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy into usb-next
Kishon writes: phy: for 4.2 merge window *) new Broadcom SATA3 PHY driver for Broadcom STB SoCs *) new phy API to get PHY by index which is used in EHCI and OHCI controller drivers *) support specifying supply at port level used for multi-port PHYs *) sparse warning fixes in miphy PHYs *) fix pm_runtime issues in twl4030 driver Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
