I have some questions:
What about the other clocks acquired in drivers/mfd/omap-usb-host.c? Shouldn't
all of those be provided by via the DT phandle?
Should the clk_get be changed to of_clk_get()/of_clk_get_by_name() in the
driver? This would potentially remove the need of the init_60m_fclk name.
$ grep clk_get drivers/mfd/omap-usb-host.c
omap->ehci_logic_fck = clk_get(dev, "ehci_logic_fck");
omap->utmi_p1_gfclk = clk_get(dev, "utmi_p1_gfclk");
omap->utmi_p2_gfclk = clk_get(dev, "utmi_p2_gfclk");
omap->xclk60mhsp1_ck = clk_get(dev, "xclk60mhsp1_ck");
omap->xclk60mhsp2_ck = clk_get(dev, "xclk60mhsp2_ck");
omap->init_60m_fclk = clk_get(dev, "init_60m_fclk");
omap->utmi_clk[i] = clk_get(dev, clkname);
omap->hsic480m_clk[i] = clk_get(dev, clkname);
omap->hsic60m_clk[i] = clk_get(dev, clkname);
