usb: mtu3: fix up undefined reference to usb_debug_root

2019-05-21T08:08:56+00:00

When CONFIG_USB is not set, and CONFIG_USB_GADGET is set, there is an issue: ld: drivers/usb/mtu3/mtu3_debugfs.o: in function 'ssusb_debugfs_create_root': mtu3_debugfs.c:(.text+0xba3): undefined reference to 'usb_debug_root' usb_debug_root is only built when CONFIG_USB is enabled, so here drop it and use NULL instead.

usb: mtu3: get optional clock by devm_clk_get_optional()

2019-04-19T12:24:26+00:00

Use devm_clk_get_optional() to get optional clock instead of optional_clk_get() which uses devm_clk_get() to get clock and checks for -EPROBE_DEFER but not -ENOENT as devm_clk_get_optional() does, in fact, only ignoring -ENOENT will cover more errors, so the replacement doesn't change original purpose.

Merge 5.1-rc3 into usb-next

We want the USB fixes in here as well. Signed-off-by: Greg Kroah-Hartman

usb: mtu3: fix EXTCON dependency

2019-03-26T07:48:56+00:00

When EXTCON is a loadable module, mtu3 fails to link as built-in: drivers/usb/mtu3/mtu3_plat.o: In function `mtu3_probe': mtu3_plat.c:(.text+0x690): undefined reference to `extcon_get_edev_by_phandle' Add a Kconfig dependency to force mtu3 also to be a loadable module if extconn is, but still allow it to be built without extcon.

usb: mtu3: add a function to switch mailbox state to string

usb: mtu3: add tracepoints to help debug

2019-03-26T07:40:14+00:00

This patch implements a few initial tracepoints for the mtu3 driver. More traces can be added as necessary in order to ease the task of debugging. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c

2019-03-26T07:40:14+00:00

Due to the separated debugfs files are added, move vbus and mode debugfs interfaces related with dual-role switch from mtu3_dr.c into mtu3_debugfs.c Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: add debugfs interface files

2019-03-26T07:40:14+00:00

This adds more debugfs consumers. The debugfs entries read some important registers, fifo status, QMU ring, endpoint status, and IPPC probe interface to get internal status. With these entries, users can check the registers, endpoint and GPD used during run time. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: supports new QMU format

usb: mtu3: rebuild qmu_gpd struct to prepare to support new QMU format

2019-03-26T07:40:13+00:00

To support USB3 Gen2 ISOC, the data buffer length need be extended, it's hard to make the current qmu_gpd struct compatible, so here rebuild qmu_gpd struct and make easy to support new QMU format Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman
