2020-09-09net: cavium: Fix a bunch of kerneldoc parameter issuesWang Hai1-5/+5
Rename ptp to ptp_info. Fix W=1 compile warnings (invalid kerneldoc): drivers/net/ethernet/cavium/common/cavium_ptp.c:94: warning: Excess function parameter 'ptp' description in 'cavium_ptp_adjfine' drivers/net/ethernet/cavium/common/cavium_ptp.c:141: warning: Excess function parameter 'ptp' description in 'cavium_ptp_adjtime' drivers/net/ethernet/cavium/common/cavium_ptp.c:163: warning: Excess function parameter 'ptp' description in 'cavium_ptp_gettime' drivers/net/ethernet/cavium/common/cavium_ptp.c:185: warning: Excess function parameter 'ptp' description in 'cavium_ptp_settime' drivers/net/ethernet/cavium/common/cavium_ptp.c:208: warning: Excess function parameter 'ptp' description in 'cavium_ptp_enable' Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Wang Hai <wanghai38@huawei.com> Signed-off-by: David S.

2020-04-02net: cavium: Fix build errors due to 'imply CAVIUM_PTP'YueHaibing1-1/+1
If CAVIUM_PTP is m and THUNDER_NIC_VF is y, build fails: drivers/net/ethernet/cavium/thunder/nicvf_main.o: In function 'nicvf_remove': nicvf_main.c:(.text+0x1f0): undefined reference to 'cavium_ptp_put' drivers/net/ethernet/cavium/thunder/nicvf_main.o: In function `nicvf_probe': nicvf_main.c:(.text+0x557c): undefined reference to 'cavium_ptp_get' THUNDER_NIC_VF imply CAVIUM_PTP, which allow the config now, Use IS_REACHABLE() to avoid the vmlinux link error for this case.

2020-03-02net: cavium: Register driver with PCI subsys IDsPrakash Brahmajyosyula1-1/+9
Across Cavium's ThunderX and Marvell's OcteonTx2 silicons the PTP timestamping block's PCI device ID and vendor ID have remained same but the HW architecture has changed. Hence added PCI subsystem IDs to the device table to avoid this driver from being probed on OcteonTx2 silicons.

2019-10-15net: cavium: Use the correct style for SPDX License IdentifierNishad Kamdar1-1/+1
This patch corrects the SPDX License Identifier style in header files related to Cavium Ethernet drivers. 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.

2019-08-18net: cavium: fix driver nameStephen Hemminger1-1/+1
The driver name gets exposed in sysfs under /sys/bus/pci/drivers so it should look like other devices. Change it to be common format (instead of "Cavium PTP"). This is a trivial fix that was observed by accident because Debian kernels were building this driver into kernel (bug).
