The Flexcan on i.MX8QM supports CAN FD protocol. Signed-off-by:

The CAN-FD protocol allows the transmission and reception of data at a higher bit rate than the nominal rate used in the arbitration phase when the message's BRS bit is set. The TDC mechanism is effective only during the data phase of FD frames having BRS bit set. It has no effect either on non-FD frames, or on FD frames transmitted at normal bit rate. Signed-off-by:

ISO CAN FD is introduced to increase the failture detection capability than non-ISO CAN FD. The non-ISO CAN FD is still supported by FlexCAN so that it can be used mainly during an intermediate phase, for evaluation and development purposes. Therefore, it is strongly recommended to configure FlexCAN to the ISO CAN FD protocol by setting the ISOCANFDEN field in the CTRL2 register. NOTE: If you only set "fd on", driver will use ISO FD mode by default. You should set "fd-non-iso on" after setting "fd on" if you want to use NON ISO FD mode. Signed-off-by:

This patch adds CAN-FD mode support to the driver, it means that payload size can extend up to 64 bytes. Bit timing always set in the CBT register, not in the CTRL1 register any more. This has an extend range of all CAN bit timing variables (PRESDIV, PROPSEG, PSEG1, PSEG2 and RJW), which will improve the bit timing accuracy. Signed-off-by:

On the i.MX7D in LPSR mode, the controller will be powered off and the configuration state is lost after system resume. Upcoming i.MX8QM/QXP will also completely power off the domain, the controller state is lost and needs restore, too. So we need to set the pinctrl state again and re-start chip to re-configuration after resume. For the wakeup case, it should not set pinctrl to sleep state by pinctrl_pm_select_sleep_state. If the interface is down before suspend, we don't need to re-configure it as it will be configured if the interface is brought up later. Signed-off-by:

This patch implements error handling and propagates the error value of flexcan_chip_stop(). This function will be called from flexcan_suspend() in an upcoming patch in some SoCs which support LPSR mode. Add a new function flexcan_chip_stop_disable_on_error() that tries to disable the chip even in case of errors. Signed-off-by:

commit cdce8448 ("can: flexcan: add vf610 support for FlexCAN") From above commit by Stefan Agner, the patch just disables non-correctable errors interrupt and freeze mode. It still can correct the correctable errors since ECC enabled by default after reset (MECR[ECCDIS]=0, enable memory error correct) if HW supports ECC. commit 5e269324 ("can: flexcan: disable completely the ECC mechanism") From above commit by Joakim Zhang, the patch disables ECC completely (assert MECR[ECCDIS]) according to the explanation of FLEXCAN_QUIRK_DISABLE_MECR that disable memory error detection. This cause correctable errors cannot be corrected even HW supports ECC. The error correction mechanism ensures that in this 13-bit word, errors in one bit can be corrected (correctable errors) and errors in two bits can be detected but not corrected (non-correctable errors). Errors in more than two bits may not be detected. If HW supports ECC, we can use this to correct the correctable errors detected from FlexCAN memory. Then disable non-correctable errors interrupt and freeze mode to avoid that put FlexCAN in freeze mode. This patch adds correctable errors correction when HW supports ECC, and modify explanation for FLEXCAN_QUIRK_DISABLE_MECR. Signed-off-by:

Merge tag 'linux-can-next-for-5.10-20200921' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2020-09-21 this is a pull request of 38 patches for net-next. the first 5 patches are by Colin Ian King, Alexandre Belloni and me and they fix various spelling mistakes. The next patch is by me and fixes the indention in the CAN raw protocol according to the kernel coding style. Diego Elio Pettenò contributes two patches to fix dead links in CAN's Kconfig. Masahiro Yamada's patch removes the "WITH Linux-syscall-note" from SPDX tag of C files. AThe next 4 patches are by me and target the CAN device infrastructure and add error propagation and improve the output of various messages to ease driver development and debugging. YueHaibing's patch for the c_can driver removes an unused inline function. Next follows another patch by Colin Ian King, which removes the unneeded initialization of a variable in the mcba_usb driver. A patch by me annotates a fallthrough in the mscan driver. The ti_hecc driver is converted to use devm_platform_ioremap_resource_byname() in a patch by Dejin Zheng. Liu Shixin's patch converts the pcan_usb_pro driver to make use of le32_add_cpu() instead of open coding it. Wang Hai's patch for the peak_pciefd_main driver removes an unused makro. Vaibhav Gupta's patch converts the pch_can driver to generic power management. Stephane Grosjean improves the pcan_usb usb driver by first documenting the commands sent to the device and by adding support of rxerr/txerr counters. The next patch is by me and cleans up the Kconfig of the CAN SPI drivers. The next 6 patches all target the mcp251x driver, they are by Timo Schlüßler, Andy Shevchenko, Tim Harvey and me. They update the DT bindings documentation, sort the include files alphabetically, add GPIO support, make use of the readx_poll_timeout() helper, and add support for half duplex SPI-controllers. Wolfram Sang contributes a patch to update the contact email address in the mscan driver, while Zhang Changzhong updates the clock handling. The next patch is by and updates the rx-offload infrastructure to support callback less usage. The last 6 patches add support for the mcp25xxfd CAN SPI driver. First the dt-bindings are added by Oleksij Rempel, the regmap infrastructure and the main driver is contributed by me. Kurt Van Dijck adds listen-only support, Manivannan Sadhasivam adds himself as maintainer, and Thomas Kopp himself as a reviewer. ==================== Signed-off-by:

In mt7531_cpu_port_config(), if the variable port is neither 5 nor 6, then variable interface will be used uninitialised. Change the function to return -EINVAL in this case. As the return value of mt7531_cpu_port_config() is never checked (even though it returns an int) add a check in the correct place so that the error can be passed up the call stack. Now that we correctly handle errors thrown in this function, also check the return value of mt7531_mac_config() in case an error occurs here. Also add misisng checks to mt7530_setup() and mt7531_setup(), which are another level further up the call stack.

Currently the backlog status in not exposed to user-space. Since long backlogs (or simply not empty ones) can be a source of noticeable latency, -RT deployments need some way to inspect it. Additionally, there isn't a direct match between 'softnet_stat' lines and the related CPU - sd for offline CPUs are not dumped - so this patch also includes the CPU id into such entry. Signed-off-by:

The PCI vendor IDs in the documentation inaccurately describe the ENA devices. For example, the 1d0f:ec20 can have LLQ support. The driver loads in LLQ mode by default, and a message is printed to the kernel ring if the mode isn't supported by the device, so the device table isn't needed. Also, LLQ can support various entry sizes, so the documentation is updated to reflect that. Interrupt moderation description is also updated to be more accurate. Signed-off-by:

After running Sparse checker on the driver using make C=1 M=drivers/net/ethernet/amazon/ena the only error that is thrown is: sparse: sparse: Using plain integer as NULL pointer about the line struct ena_calc_queue_size_ctx calc_queue_ctx = { 0 }; This patch fixes this warning, thus making our driver free (for now) of Sparse errors/warnings. To make a more complete work, this patch also fixes all static warnings that were found using an internal static checker. Signed-off-by:Ido Segev <idose@amazon.com> Signed-off-by:

The formal name changes to "ENA_ADMIN_RSS_INDIRECTION_TABLE_CONFIG". Indirection is the ability to reference "something" using "something else" instead of the value itself. Indirection table, as the name implies, is the ability to reference CPU/Queue value using hash-to-CPU table instead of CPU/Queue itself. This patch renames the variable keys_num, which describes the number of words in the RSS hash key, to key_parts which makes its purpose clearer in RSS context. Signed-off-by:

Make log prints in ena_netdev use the same log functions as the rest of the driver. For the sake of consistency, all prints in ena_netdev file were converted into netif_* format except where netdev struct isn't yet defined. For these places, dev_* log functions are used (similar to the patch for ena_com files). This commit leaves some corner cases which would be changed in a future patch. Signed-off-by:
