Hello All and especially Dan Murphy, Reading thru the mailing list Dan seems to have worked on usb3503a + LAN9730 enumeration wrt the OMAP5. Hence, I seek his help and anyone else!
This is with regards to an odroid-u2. It is Exynos 4412 prime based. It has a usb3503a hub and also a LAN 9730 - I am guessing pretty much like the omap5.
From the clock source and the PMIC perspective I do see that the usb3503a is powered up and gets a REF_CLK. (I can verify this as I can read and write via I2C to the usb3503a and get/set its configuration.
Did you also check the basic host operation, if you have any external port coming out of USB2.0 PHY (not HSIC phy) where you can connect a mass storage device or n/w device may be and see if that's getting enumerated.
Also, I do have the correct GPIO pins for the INT_N, RESET_N and HUB_CONNECT wrt the usb3503a.
So are you doing a proper reset of USB3503 hub using RESET_N line ? Basically what i could see from Linaro's git also and they are doing a pull-down followed by pull-up of RESET_N and HUB_CONNECT gpios when setting up the HSIC phy.
Please have a look at following patch if this helps: https://launchpadlibrarian.net/122816176/0001-DRIVERS-USB-Initialize-HSIC-PH...
In the platform based ehci-exynos.c I do initialize the the USB_PHY, HSIC_1_PHY and HSIC2_PHY that is present in the Exynos 4412 SoC. These I have copied over from the Linux kernel (which has full usb support and works). Once this is done, I can see that the values for hccr and hcor appear correct as reported by Linux too.
Can you attach the patch here which you are using for setting up the required PHY settings. In the first look there's PHY that is to be suspected.
When it comes to starting up usb via usb start, I seem to hit the below sequence - with debug on ... The u-boot is quite an older u-boot, but I have ported most of the usb code over from the arndale port over at insignal - which seems to have usb working (they too have a usb3503a but with exynos5)
My question is how do I debug this to get it working. Looks like the hcd does not see the usb3503a, am I correct? ---------------------------- 8< ---------------------------- (Re)start USB...
