ARM: davinci: da8xx: Fix sleeping function called from invalid context
Everytime the usb20 phy is enabled, there is a
"sleeping function called from invalid context" BUG.
In addition, there is a recursive locking happening
because of the recurse call to clk_enable().
clk_enable() from arch/arm/mach-davinci/clock.c uses
spin_lock_irqsave() before to invoke the callback
usb20_phy_clk_enable(). usb20_phy_clk_enable() uses
clk_get() and clk_enable_prepapre() which may sleep.
Replace clk_prepare_enable() by davinci_clk_enable().
