2020-09-21can: spi: Kconfig: remove unneeded dependencies form Kconfig symbolsMarc Kleine-Budde1-2/+0
Since commits 653ee35ce6d5 ("can: hi311x: remove custom DMA mapped buffer") Fixes: df58525df395 ("can: mcp251x: remove custom DMA mapped buffer") both the hi3111x and the mcp251x driver don't make use of the DMA API any more. So we can safely remove the HAS_DMA dependency. While we're here, remove the unneeded CAN_DEV and SPI dependencies from the CAN_HI311X symbol, as the parent menus already have these dependencies.

2020-09-21can: pcan_usb: add support of rxerr/txerr countersStephane Grosjean1-16/+117
This patch adds the support of the rx/tx errors CAN counters to the driver of the PCAN-USB PC-CAN interface from PEAK-System GmbH. The PCAN-USB is capable of giving back the values of the rx/tx errors counters, to provide more details and statistics to the linux-can layer. Getting these values allows the driver to better tune CAN_ERR_CRTL_TX_xxx and CAN_ERR_CRTL_RX_xxx bits in case of the interface enters any CAN_STATE_ERROR_xxx state.

2020-09-21can: pch_can: use generic power managementVaibhav Gupta1-42/+21
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

2020-09-20bnxt_en: return proper error codes in bnxt_show_tempEdwin Peer1-6/+13
Returning "unknown" as a temperature value violates the hwmon interface rules. Appropriate error codes should be returned via device_attribute show instead. These will ultimately be propagated to the user via the file system interface. In addition to the corrected error handling, it is an even better idea to not present the sensor in sysfs at all if it is known that the read will definitely fail. Given that temp1_input is currently the only sensor reported, ensure no hwmon registration if TEMP_MONITOR_QUERY is not supported or if it will fail due to access permissions. Something smarter may be needed if and when other sensors are added.

2020-09-20net: dsa: tag_8021q: add VLANs to the master interface tooVladimir Oltean1-1/+6
The whole purpose of tag_8021q is to send VLAN-tagged traffic to the CPU, from which the driver can decode the source port and switch id. Currently this only works if the VLAN filtering on the master is disabled. Change that by explicitly adding code to tag_8021q.c to add the VLANs corresponding to the tags to the filter of the master interface. Because we now need to call vlan_vid_add, then we also need to hold the RTNL mutex. Propagate that requirement to the callers of dsa_8021q_setup and modify the existing call sites as appropriate. Note that one call path, sja1105_best_effort_vlan_filtering_set -> sja1105_vlan_filtering -> sja1105_setup_8021q_tagging, was already holding this lock.
