This series adds :
	_ add reset driver
	_ update existing sdhci driver to use reset framework
	_ add usb phy driver
	_ add ehci support
	_ add ohci support
	_ add xhci support
	_ add fastboot support

With all this feature enable, it's now possible to 
	_ boot on usb mass storage device
	_ boot from kernel image and dtb previously loaded using tftp
	_ update mmc partiton using fastboot
	
v2:	_ add Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com> in patches 2,3 and 4
	_ fix remarks done by Marek Vasut :
		_ patch 5 : replace bitfield_replace() by clrsetbits_le32()
		_ patch 6 : update error messages and add remove callback
		_ patch 8 : put board specific defines in a separate patch
		_ patch 7: use setbits_le32() instead of read, modify, write
		  sequence and add missing parenthesis
		_ squash previous patches 7,9,11,12,14,16,17,18,19,20 and 21
		  in patch 14

From: Patrice Chotard <patrice.chotard@st.com>

This patch adds a reset controller implementation for STMicroelectronics
STi family SoCs; it allows a group of related reset like controls found
in multiple system configuration registers to be represented by a single
controller device.

Driver code has been mainly extracted from kernel
drivers/reset/sti/reset-stih407.c

Add support for on-chip DWC3 controller available
on STMicrolectronics STiH407 family SoCs.
On B2260 board, the type AB USB connector is managed
by a DWC3 IP. As USB3 signals are not wired, only USB2
is supported.

From: Patrice Chotard <patrice.chotard@st.com>

This patch adds the ST glue logic to manage the DWC3 HC
on STiH407 SoC family. It configures the internal glue
logic and syscfg registers.

Part of this code been extracted from kernel.org driver
(drivers/usb/dwc3/dwc3-st.c)

v2:	_ use setbits_le32() instead of read, modify, write sequence

Is it possible to replace the above two calls with
uclass_get_device_by_phandle()?

I have send a v3 of this series on 28th April in which i have 
implemented a simple USB PHY UCLASS as you requested in [1]

This function is needed for fastboot feature. When using "fastboot" 
command the do_fastboot() call board_usb_init() implemented in each 
architecture board file.

It will be called from board_usb_init() in board/st/stih410-b2260/board.c

But, please refer to my last series (v3 send on 28th April 2017)

Thanks
