usb: mtu3: fix EXTCON dependency

2019-03-26T07:48:56Z

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: add missing SPDX lines to Kconfig and Makefiles

2019-01-22T08:08:17Z

There are a few remaining drivers/usb/ files that do not have SPDX identifiers in them, all of these are either Kconfig or Makefiles. Add the correct GPL-2.0 identifier to them to make scanning tools happy. Signed-off-by: Greg Kroah-Hartman

usb: mtu3: fix dbginfo in qmu_tx_zlp_error_handler

Fixes gcc '-Wunused-but-set-variable' warning: drivers/usb/mtu3/mtu3_qmu.c: In function 'qmu_tx_zlp_error_handler': drivers/usb/mtu3/mtu3_qmu.c:385:22: warning: variable 'req' set but not used [-Wunused-but-set-variable] It seems dbginfo original intention is print 'req' other than 'mreq' Acked-by: Chunfeng Yun Signed-off-by: YueHaibing Signed-off-by: Felipe Balbi

usb: mtu3: clear SOFTCONN when clear USB3_EN if work as HS mode

2018-12-05T09:12:28Z

When the controller supports SS mode, but works as HS mode, the SOFTCONN will not be cleared automatically when clear USB3_EN by default, this cause an issue that can't disconnect from host, so clear SOFTCONN when clear USB3_EN when the class driver want to disable the D+ pullup.

usb: mtu3: enable SETUPENDISR interrupt

2018-12-05T09:12:25Z

If the controller receives a new SETUP during SETUP data stage, and will generate SETUPENDISR interrupt, the driver should abort the current SETUP command and process the new one. Signed-off-by: Chunfeng Yun Signed-off-by: Felipe Balbi

usb: mtu3: fix the issue about SetFeature(U1/U2_Enable)

2018-12-05T09:12:23Z

Fix the issue: device doesn't accept LGO_U1/U2: 1. set SW_U1/U2_ACCEPT_ENABLE to eanble controller to accept LGO_U1/U2 by default; 2. enable/disable controller to initiate requests for transition into U1/U2 by SW_U1/U2_REQUEST_ENABLE instead of SW_U1/U2_ACCEPT_ENABLE; Signed-off-by: Chunfeng Yun Signed-off-by: Felipe Balbi

usb: mtu3: enable hardware remote wakeup from L1 automatically

2018-12-05T09:12:19Z

Enable hardware remote wakeup from L1 automatically based on the FIFO status, instead of manual way. Signed-off-by: Chunfeng Yun Signed-off-by: Felipe Balbi

usb: mtu3: remove QMU checksum

2018-12-05T09:12:16Z

The QMU checksum calculation is redundant, mostly used by debug, so remove it here. Signed-off-by: Chunfeng Yun Signed-off-by: Felipe Balbi

usb/mtu3: power down device ip at setup

2018-12-05T09:12:02Z

Originally, when dr_mode is USB_DR_MODE_HOST, it didn't power down device ip, so host ip sleep will fail at ssusb_host_disable. Power down device ip at ssusb_host_setup. Acked-by: Chunfeng Yun Signed-off-by: Hsin-Yi, Wang Signed-off-by: Felipe Balbi
