Hi,
This series of patches adds,
a) Multi instances support in musb driver
b) DT support for musb_dsps glue layer
c) DT support for NOP transceiver
AM33xx and TI81xx has dual musb controller and has two usb PHY of same type.
This patch series uses 'phandle' based API devm_usb_get_phy_by_phandle()
Moved global variable "musb_debugfs_root" and static variable
"old_state" to 'struct musb' to help support multi instance of
musb controller as present on AM335x platform.
Also removed the global variable "orig_dma_mask" and filled the
dev->dma_mask with parent device's dma_mask.
