This series adds USB 2.0 support for the RZ/G1C SoC. RZ/G1C SoC is similar to R-Car Gen2 SoC, but there are some differences - It has a shared pll reset register for hsusb0/hsusb1 and this register reside in hsusb0 block. - Each USB host needs to deassert the pll reset of hsusb block apart from initializing interrupt enable,OVC detection timer and suspend/resume timer register. To address the above scenarios, created a ehci-r8a77470 host controller driver. This patchset is based on linux_next next-20190401 branch.
