2020-07-09usb: mtu3: mtu3_debug: Add forward declaration of 'struct ssusb_mtk'Lee Jones1-0/+2
Without it, the build system complains that it was declared inside the parameter list. Fixes the following W=1 kernel build warning(s): In file included from drivers/usb/mtu3/mtu3_trace.c:11: drivers/usb/mtu3/mtu3_debug.h:29:36: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration 29 | void ssusb_dev_debugfs_init(struct ssusb_mtk *ssusb); | ^~~~~~~~~ drivers/usb/mtu3/mtu3_debug.h:30:35: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration 30 | void ssusb_dr_debugfs_init(struct ssusb_mtk *ssusb); | ^~~~~~~~~ drivers/usb/mtu3/mtu3_debug.h:31:39: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration 31 | void ssusb_debugfs_create_root(struct ssusb_mtk *ssusb); | ^~~~~~~~~ drivers/usb/mtu3/mtu3_debug.h:32:39: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration 32 | void ssusb_debugfs_remove_root(struct ssusb_mtk *ssusb); | ^~~~~~~~~ Cc: Chunfeng Yun <[email protected]> Cc: [email protected] Signed-off-by: Lee Jones <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2020-04-16USB: mtu3: Use the correct style for SPDX License IdentifierNishad Kamdar1-1/+1
This patch corrects the SPDX License Identifier style in header files related to MediaTek USB3 Dual Role controller. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

2019-03-26usb: mtu3: add tracepoints to help debugChunfeng Yun1-0/+8
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 <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2019-03-26usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.cChunfeng Yun1-0/+2
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 <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2019-03-26usb: mtu3: add debugfs interface filesChunfeng Yun1-0/+40
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 <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
