Subject: [PATCH] phy: usb: Get all drivers that use USB clks using correct
|
|
enable/disable
|
|
|
|
The BRCM USB Phy, ohci, ehci and xhci drivers all use the USB clocks
|
|
but not all drivers use the clk_prepare_enable/clk_disable_unprepare
|
|
versions to enable/disable the clocks. This change gets all drivers
|
|
using the prepare version.
