The TXFQS register is read first to check if the fifo is full and then immediately again to get the putidx. This is unnecessary and adds significant overhead if read requests are done over a slow bus, for example SPI with tcan4x5x. Add a variable to store the value of the register.

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: The goal of this series is to report the firmware version, the bootloader version and the hardware revision of ETAS ES58x devices. These are already reported in the kernel log but this isn't best practice. Remove the kernel log and instead export all these through devlink. The devlink core automatically exports the firmware and the bootloader version to ethtool, so no need to implement the ethtool_ops::get_drvinfo() callback anymore. Patch one and two implement the core support for devlink (at device level) and devlink port (at the network interface level). Patch three export usb_cache_string() and patch four add a new info attribute to devlink.h. Both are prerequisites for patch five. Patch five is the actual goal: it parses the product information from a custom usb string returned by the device and expose them through devlink. Patch six removes the product information from the kernel log. Finally, patch seven add a devlink documentation page with list all the information attributes reported by the driver. * Sample outputs following this series * | $ devlink dev info | usb/1-9:1.1: | serial_number 0108954 | versions: | fixed: | board.rev B012/000 | running: | fw 04.00.01 | fw.bootloader 02.00.00 | $ devlink port show can0 | usb/1-9:1.1/0: type eth netdev can0 flavour physical port 0 splittable false | $ ethtool -i can0 | driver: etas_es58x | version: 6.1.0-rc7+ | firmware-version: 04.00.01 02.00.00 | expansion-rom-version: | bus-info: 1-9:1.1 | supports-statistics: no | supports-test: no | supports-eeprom-access: no | supports-register-dump: no | supports-priv-flags: no * Changelog * v4 -> v5: https://lore.kernel.org/all/20221130174658.29282-1-mailhol.vincent@wanadoo.fr * [PATH 2/7] add devlink port support. This extends devlink to the network interface. * thanks to devlink port, 'ethtool -i' is now able to retrieve the firmware version from devlink. No need to implement the ethtool_ops::get_drvinfo() callback anymore: remove one patch from the series. * [PATCH 4/7] A new patch to add a new info attribute for the bootloader version in devlink.h. This patch was initially sent as a standalone patch here: https://lore.kernel.org/netdev/20221129031406.3849872-1-mailhol.vincent@wanadoo.fr Merging it to this series so that it is both added and used at the same time. * [PATCH 5/7] use the newly info attribute defined in patch 4/7 to report the bootloader version instead of the custom string "bl". * [PATCH 5/7] because the series does not implement ethtool_ops::get_drvinfo() anymore, the two helper functions es58x_sw_version_is_set() and es58x_hw_revision_is_set() are only used in devlink.c. Move them from es58x_core.h to es58x_devlink.c. * [PATCH 5/7] small rework of the helper function es58x_hw_revision_is_set(): it is OK to only check the letter (if the letter is '\0', it will not be possible to print the next numbers). * [PATCH 5/7 and 6/7] add reviewed-by Andrew Lunn tag. * [PATCH 7/7] Now, 'ethtool -i' reports both the firmware version and the bootloader version (this is how the core export the information from devlink to ethtool). Update the documentation to reflect this fact. * Reoder the patches. v3 -> v4: https://lore.kernel.org/all/20221126162211.93322-1-mailhol.vincent@wanadoo.fr * major rework to use devlink instead of sysfs following Andrew's comment. * split the series in 6 patches. * [PATCH 1/6] add Acked-by: Greg Kroah-Hartman v2 -> v3: https://lore.kernel.org/all/20221113040108.68249-1-mailhol.vincent@wanadoo.fr * patch 2/3: do not spam the kernel log anymore with the product number. Instead parse the product information string, extract the firmware version, the bootloadar version and the hardware revision and export them through sysfs. * patch 2/3: rework the parsing in order not to need additional fields in struct es58x_parameters. * patch 3/3: only populate ethtool_drvinfo::fw_version because since commit edaf5df2 ("ethtool: ethtool_get_drvinfo: populate drvinfo fields even if callback exits"), there is no need to populate ethtool_drvinfo::driver and ethtool_drvinfo::bus_info in the driver. v1 -> v2: https://lore.kernel.org/all/20221104171604.24052-1-mailhol.vincent@wanadoo.fr * was a single patch.

"renesas,r9a07g043-canfd" compatible string will be used on the RZ/Five SoC so to make this clear, update the comment to include RZ/Five SoC. No driver changes are required as generic compatible string "renesas,rzg2l-canfd" will be used as a fallback on RZ/Five SoC. Signed-off-by:

Add support for devlink port which extends the devlink support to the network interface level. For now, the etas_es58x driver will only rely on the default features that devlink port has to offer and not implement additional feature ones. Signed-off-by:

IMX93 do not contain a GPR to config the stop mode, it will set the flexcan into stop mode automatically once the ARM core go into low power mode (WFI instruct) and gate off the flexcan related clock automatically. But to let these logic work as expect, before ARM core go into low power mode, need to make sure the flexcan related clock keep on. To support stop mode and wakeup feature on imx93, this patch add a new fsl_imx93_devtype_data to separate from imx8mp. Signed-off-by:

Since commit 0166dc11 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. Signed-off-by:

Biju Das <biju.das.jz@bp.renesas.com> says: The CAN FD IP found on RZ/G2L SoC has some HW features different to that of R-Car. For example, it has multiple resets, dedicated channel tx and error interrupts, separate global rx and error interrupts compared to shared irq for R-Car. it does not s ECC error flag registers and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels whereas other SoCs has only 2 channels. Currently all the HW differences are handled by comparing with chip_id enum. This patch series aims to replace chip_id with struct rcar_canfd_hw_info to handle the HW feature differences and driver data present on both IPs. The changes are trivial and tested on RZ/G2L SMARC EVK. This patch series depend upon [1].

Xin Long says: ==================== net: eliminate the duplicate code in the ct nat functions of ovs and tc The changes in the patchset: "net: add helper support in tc act_ct for ovs offloading" had moved some common ct code used by both OVS and TC into netfilter. There are still some big functions pretty similar defined and used in each of OVS and TC. It is not good to maintain such big function in 2 places. This patchset is to extract the functions for NAT processing from OVS and TC to netfilter. To make this change clear and safe, this patchset gets the common code out of OVS and TC step by step: The patch 1-4 make some minor changes in OVS and TC to make the NAT code of them completely the same, then the patch 5 moves the common code to the netfilter and exports one function called by each of OVS and TC. v1->v2: - Create nf_nat_ovs.c to include the nat functions, as Pablo suggested. v2->v3: - fix a typo in subject of patch 2/5, as Marcelo noticed. - fix in openvswitch to keep OVS ct nat and TC ct nat consistent in patch 3/5 instead of in tc, as Marcelo noticed. - use BIT(var) macro instead of (1 << var) in patch 5/5, as Marcelo suggested. - use ifdef in netfilter/Makefile to build nf_nat_ovs only when OVS or TC ct action is enabled in patch 5/5, as Marcelo suggested. v3->v4: - add NF_NAT_OVS in netfilter/Kconfig and add select NF_NAT_OVS in OVS and TC Kconfig instead of using ifdef in netfilter/Makefile, as Pablo suggested. ==================== Signed-off-by:
