[PATCH 0/2] mach-meson: port dwc2_otg usage to CONFIG_DM_USB_GADGET=y

While working on some USB bugs on the VIM3L board, we stumbled upon the fact that mach-meson still uses legacy board_usb_*() functions instead of using DM [1]
This series aim to switch the g12a based boards to use CONFIG_DM_USB_GADGET and removes the board_usb_*() logic.
* The first patch adds mode switching in the dwc3-meson-g12a glue driver whenever the dwc2 otg driver is probed()/removed().
* The second patch enables the config option and cleans up all board_usb_*().
This has been mainly tested with khadas-vim3l_android_defconfig using fastboot:
=> fastboot usb 0
=> # hit Ctrl-c
Other tests: * ums 0 mmc 2 # can list / mount partitions from host * usb start; usb storage # list usb thumb drive * all defconfigs have been build tested

Best regards,

arch/mach-meson has some custom usb logic, in particular: * on board_usb_init(), we force USB_DR_MODE_PERIPHERAL * on board_usb_cleanup(), we force USB_DR_MODE_HOST
With DM_USB_GADGET=y, board_usb_init/cleanup() are no longer used when we call usb_gadget_initialize(). Instead, the generic (from udc-uclass) initialization/release is called, which itself calls the controller driver's probe()/remove().
Therefore, enabling DM_USB_GADGET=y will mean that this mode switching will break.
To prepare for enabling DM_USB_GADGET, perform the mode switching when the "amlogic,meson-g12a-usb" (dwc2) driver is probed()/removed() instead.
This is achieved via the glue driver, which gets notified each time one of its children is probed()/removed.
Note: this change should be harmless without DM_USB_GADGET=y because the amlogic-g12a-usb driver is not probed via driver model.

With CONFIG_DM_USB_GADGET=y, we no longer need any board_usb_*() logic because: * the dwc2 driver is DM compatible, and handles its own clock enabling * the dwc3-meson-g12a glue drivers handles "force mode switching"
Remove all mach-meson/g12a usb code and enable CONFIG_DM_USB_GADGET.
Note: Only configs having both CONFIG_USB_DWC3_MESON_G12A=y *and* USB_GADGET_DWC2_OTG=y have been updated.

I got my hands on an odroid-c4 board and I also tested: => fastboot usb 0 => # hit Ctrl-c # disconnection is ok
And tested "usb start" and could list a usb thumb drive.
Any other tests you would like me to do?

Hi Neil,

I'll run some tests on other G12 boards but so far this looks very good, thanks !
I got my hands on an odroid-c4 board and I also tested: => fastboot usb 0 => # hit Ctrl-c # disconnection is ok
And tested "usb start" and could list a usb thumb drive.
Any other tests you would like me to do?
No it's enough, thx for testing on the C4, this test the Device/Host switch is still working !
Marek, can you take the whole patchset with my Acked-by or should I take it ?

Hi Neil, Marek,
Anything blocking to pick this up? I see it's assigned to Neil on patchwork, but it's mostly usb related.
I've just re-tested the series on top of usb/master, if that helps.
Thanks you, Mattijs

Marek,
I'm ready to merge it, is it ok for you ?

While working on some USB bugs on the VIM3L board, we stumbled upon the fact that mach-meson still uses legacy board_usb_*() functions instead of using DM [1]
This series aim to switch the g12a based boards to use CONFIG_DM_USB_GADGET and removes the board_usb_*() logic.
- The first patch adds mode switching in the dwc3-meson-g12a glue driver whenever the dwc2 otg driver is probed()/removed().
