[U-Boot] [PATCH v6 00/11] Add support for DM_USB and DM_USB_DEV for TI's DRA7 EVMs and AM57 EVMs platforms.
Moving to DM_USB and DM_USB_DEV brings some benefits: - it is required to support DM_ETH and USB network adapters with the same binary. - support for USB3 on AM57x comes almost for free - removal of platform code related to USB
Tested on: - dra76 evm - AM572 evm
This series applies on top of the master branch of the u-boot USB tree (git://git.denx.de/u-boot-usb.git master)
Changes in v6: - ti-pipe3-phy: take PLL out of IDLE in pipe3_init(). The PLL may have been put into idle by pipe3_exit() - DRA7 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of DWC3_OF_SIMPLE. disable non DM USB options - AM57 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of DWC3_OF_SIMPLE. disable non DM USB options - Supports DM USB for peripherals - Removed DTS changes that disabled USB1 on DRA7 because DM_USB_DEV is now supported
Changes in v5: - Rebased on latest u-boot - Removed patches that have already been merged
Changes in v4: - Fix word missing in commit log - Remove dependency on MISC - Renamed the commit (DM_USB is already enabled, the only missing option is for the USB2 phy driver) - Remove dependency on MISC - Remove omap specific glue layer and use dwc3-of-simple glue layer
Changes in v3: - in syscon_regmap_lookup_by_phandle(), use dev_dbg() instead of printf() - added unit test for syscon_regmap_lookup_by_phandle()
Changes in v2: - Add USB3 support to ti-pipe3-phy driver - omap-usb2-phy: Implement power_on and power_off callbacks - am57xx boards: when DM_USB is used, turn on the required USB clocks - split dts changes in 2 commits: one for binding the children of ocp2scp@4a080000, and one to disable USB1 on all DRA7 EVMs - Enable DM_USB in am57xx_evm_defconfig. USB3 (super speed) is supported.
Jean-Jacques Hiblot (9): syscon: dm: Add a new method to get a regmap from DTS phy: Add a new driver for OMAP's USB2 PHYs dwc3-generic: Add support for the TI DWC3 glue board: ti: dra7xx-evm: turn on USB clocks in late init stage dts: dra7x: make ocp2scp@4a080000 compatible with simple-bus configs: enable DM_USB and DM_USB_DEV for all DRA7 platforms configs: am57xx_evm: Enable DM_USB and DM_USB_DEV board: ti: dra7-evm: remove USB platform code board: ti: am57xx: remove USB platform code
Vignesh R (2): phy: ti-pip3-phy: Add support for USB3 PHY board; ti: am57xx: turn on USB clocks

syscon_regmap_lookup_by_phandle() can be used to get the regmap of a syscon device from a reference in the DTS. It operates similarly to the linux version of the namesake function.

If the above function returns 0, then dev is valid. Also an error is never returned in 'dev'. So you should drop these two lines.
