[U-Boot] [PATCH v2 0/4] ti: dwc3: Enable USB clocks on-demand

[U-Boot] [PATCH v2 0/4] ti: dwc3: Enable USB clocks on-demand

[Kishon Vijay Abraham I]

Patch series adds APIs to enable/disable USB clocks and then uses
these APIs to enable clocks when dwc3 is used and disable clocks
when it is inactive.

Changes from v1:
*) Rebased to latest u-boot
*) removed #ifdef's in header files

This patch series is split from [1] to contain only enabling and disabling
clocks.

[U-Boot] [PATCH v2 4/4] ARM: OMAP5/AM43xx: remove enabling USB clocks from enable_basic_clocks()

[Kishon Vijay Abraham I]

Now that we have separate function to enable USB clocks, remove
enabling USB clocks from enable_basic_clocks(). Now board_usb_init()
should take care to invoke enable_usb_clocks() for enabling
USB clocks.
