We added the following initialization of the ULPI at the bottom of
ehci_hcd_init with no result.
reg = ( 1 << 5 ) /* ULPI_FUNC_CTRL_RESET */
/* FUNCTION_CTRL_SET register */
| ( 0x05 << 16 )
/* Write */
| ( 2 << 22 )
/* PORTn */
| ((1 + 1) << 24 )
/* start ULPI access*/
| (1 << 31);
ehci_writel(0x480648A4UL, reg);
The HSB2HS_CLK still is not active as we saw on the oscilloscope. Does
anybody know how to activate the clock signal on this pin?
Help would be great.
regards,
chris.
