[PATCH 0/8] USB support for DRA7-evm

[Roger Quadros]

Hi,

This series enables the 2 USB ports on the DRA7-evm.

Patches are based on on 3.14-rc4 with balbi/next, linux-phy/next,
omap-for-v3.15/dt merged and [1] applied.

[PATCH 1/8] CLK: ti: dra7: Initialize USB_DPLL

[Roger Quadros]

USB_DPLL must be initialized and locked at boot so that
USB modules can work.

Also program USB_DLL_M2 output to half rate.

I would rather see this done using the default-rate mechanism provided here:

However, this remains to be commented by Mike whether the patch is okay 
or not.

You can add these directly under the dra7xx-clocks.dtsi file as well, as 
I don't think anybody needs to modify these. And the properties can be 
added directly under the nodes themselves.

However, this patch can't be acked yet as we have no feedback from Mike 
for the default-rate proposal.

OK. I'll wait for the "default-rate" patch to be approved first and then revise this patch based on your
suggestion. Thanks for the review.

Hi,

Resurrecting this patch, as it seems the clock-parenting stuff via DT 
hasn't really moved that much forward.

Thus, this patch has been now queued for 3.17, thanks.

[PATCH 2/8] ARM: dts: dra7-clock: Add "l3init_960m_gfclk" clock gate

[Roger Quadros]

This clock gate description was missing in older Reference manuals.
It is present on the SoC to provide 960MHz reference clock to the
internal USB PHYs.

Use l3init_960m_gfclk as parent of usb_otg_ss1_refclk960m and
usb_otg_ss2_refclk960m.

[PATCH 2/8] ARM: dts: dra7-clock: Add "l3init_960m_gfclk" clock gate

[Roger Quadros]

This clock gate description was missing in older Reference manuals.
It is present on the SoC to provide 960MHz reference clock to the
internal USB PHYs.

Use l3init_960m_gfclk as parent of usb_otg_ss1_refclk960m and
usb_otg_ss2_refclk960m.

Unfortunately it hasn't yet been included in the TRM.
I have the internal defect ID but I don't think it makes any sense here.

[PATCH 6/8] ARM: dts: omap4+: Add clocks to USB2 PHY node

[Roger Quadros]

The USB2 PHY driver expects named clocks for wakeup clock
and reference clock. Provide this information for USB2 PHY
nodes in OMAP4 and OMAP5 SoC DTS.

No we don't. Still the device seems to work without it.
This is supposed to be USB_LFPS_TX_GFCLK or USB3PHY_REF_CLK.

Any idea why it works without that on OMAP5 as well?

This is supposed to be USB_LFPS_TX_GFCLK or USB3PHY_REF_CLK.

Any idea why it works without that on OMAP5 as well?

I think it should be enabled. Did you check the status of this clock in 
CM_L3INIT_CLKSTCTRL? Moreover USB_LFPS_TX_GFCLK is an interface clock, 
so IIUC setting the module mode will enable it.

Btw how did you tell dpll_core_h13x2_ck enables USB_LFPS_TX_GFCLK?

I think it should be enabled. Did you check the status of this clock in 
CM_L3INIT_CLKSTCTRL? Moreover USB_LFPS_TX_GFCLK is an interface clock, 
so IIUC setting the module mode will enable it.

Btw how did you tell dpll_core_h13x2_ck enables USB_LFPS_TX_GFCLK?
