[PATCH 00/12] Add USB2.0 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
