From 84d2e03f9d629fe3796d577d4759388699b926ad Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Fri, 1 Apr 2011 16:53:18 -0500 Subject: mpc83xx: restrict UTMI PHY configuration to 831x parts i.e, to those parts that have PHY_CLK_VALID bits in their USB CONTROL registers: mpc8308 WU_INT, PHY_CLK_SEL, USB_EN, WU_INT_EN, ULPI_INT_EN mpc831x PHY_CLK_VALID, WU_INT, CLKIN_SEL, PHY_CLK_SEL, UTMI_PHY_EN, PLL_RESET, REFSEL, OTG_PORT, KEEP_OTG_ON, LSF_EN, USB_EN, ULPI_INT_EN mpc834x USB_EN, ULPI_INT1_EN (MPH only), ULPI_INT0_EN mpc837x USB_EN, ULPI_INT_EN (mpc832x, mpc8360 don't have a USB_EHCI_FSL compatible controller) this prevents non-831x parts from never completing cpu_init_f(), because the (non-existent) PHY_CLK_VALID bit never gets set.
