[PATCH v3 0/7] USB support for DRA7-evm

[PATCH v3 0/7] USB support for DRA7-evm

[Roger Quadros]

Hi,

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

NOTE: USB1 port is hard coded to work in peripheral mode and USB2 port
in host mode. This is due to missing ID pin interrupt in pre ver.E boards.

USB1 port doesn't in peripheral mode out of the box due to missing VBUS detection
and mailbox write. To test this I had to do a manual write to enable VBUSVALID
in the USB_UTMI_OTG_STATUS register.
	omapconf set bit 0x48880084 1

USB2 port works well in host mode.

Patches are based on 3.15-rc3.

cheers,
-roger

Changelog:

v3:
-Rearraged patches. PHY related stuff first.
-Addressed backward compatibility issue for phy-omap-usb2.

v2:
-Rebased on v3.15-rc3

[PATCH v3 1/7] phy: omap-usb2: Use generic clock names "wkupclk" and "refclk"

[Roger Quadros]

As clocks might be named differently on multiple platforms, use a generic
name in the driver and allow device tree node to specify the platform
specific clock name.

[PATCH v3 6/7] ARM: dts: dra7: Add USB related nodes

[Roger Quadros]

Add nodes for the Super Speed USB controllers, omap-control-usb,
USB2 PHY and USB3 PHY devices.

Remove ocp2scp1 address space from hwmod data as it is
now provided via device tree.

Re: [PATCH v3 6/7] ARM: dts: dra7: Add USB related nodes

[Roger Quadros]

Tony,

This patch will need to be updated for IRQ crossbar changes.

I will send a revised version of just this patch based on crossbar changes [1]

[1] - http://article.gmane.org/gmane.linux.documentation/23293

cheers,
-roger

[PATCH v4 6/7] ARM: dts: dra7: Add USB related nodes

[Roger Quadros]

Add nodes for the Super Speed USB controllers, omap-control-usb,
USB2 PHY and USB3 PHY devices.

Use IRQ crossbar for interrupts.

Remove ocp2scp1 address space from hwmod data as it is
now provided via device tree.

Hi Kishon,

Could you please pick the first 2 patches in this series for phy-next?
They are independent of the rest. Thanks.

[PATCH v3 4/7] ARM: dts: dra7-clock: Add "l3init_960m_gfclk" clock gate

[Roger Quadros]

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

Reference: DRA75x_DRA74x_ES1.1_NDA_TRM_vO.pdf, pg. 900,
Table 3-812. CM_COREAON_L3INIT_60M_GFCLK_CLKCTRL

Use l3init_960m_gfclk as parent of usb_otg_ss1_refclk960m and
usb_otg_ss2_refclk960m.

Got myself to download the latest copy of the TRM, so this patch looks 
valid.
