2022-07-26ice: Add support for PPPoE hardware offloadMarcin Szycik
Add support for creating PPPoE filters in switchdev mode. Add support for parsing PPPoE and PPP-specific tc options: pppoe_sid and ppp_proto. Example filter: tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \ 1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR Changes in iproute2 are required to use the new fields. ICE COMMS DDP package is required to create a filter as it contains PPPoE profiles. Added a warning message when loaded DDP package does not contain required profiles.

2022-07-26mmc: mediatek: add support for SDIO eint wakup IRQAxe Yang
Add support for eint IRQ when MSDC is used as an SDIO host. This feature requires SDIO device support async IRQ function. With this feature, SDIO host can be awakened by SDIO card in suspend state, without additional pin. MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC turn off clock and switch SDIO DAT1 pin to GPIO mode. And during resume, switch GPIO function back to DAT1 mode then turn on clock. Some device tree property should be added or modified in MSDC node to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since this feature depends on asynchronous interrupts, "wakeup-source", "keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and the interrupts list should be extended(the interrupt named with sdio_wakeup): &mmcX { ... interrupt-names = "msdc", "sdio_wakeup"; interrupts-extended = <...>, <&pio xxx IRQ_TYPE_LEVEL_LOW>; ... pinctrl-names = "default", "state_uhs", "state_eint"; ... pinctrl-2 = <&mmc2_pins_eint>; ... cap-sdio-irq; keep-power-in-suspend; wakeup-source; ... }; Co-developed-by: Yong Mao <yong.mao@mediatek.com> Signed-off-by: Yong Mao <yong.mao@mediatek.com> Reviewed-by: Chaotian Jing <chaotian.jing@mediatek.com> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Axe Yang <axe.yang@mediatek.com> Link: https://lore.kernel.org/r/20220726062842.18846-4-axe.yang@mediatek.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2022-07-26hwmon: (sht15) Fix wrong assumptions in device remove callbackUwe Kleine-König
Taking a lock at the beginning of .remove() doesn't prevent new readers. With the existing approach it can happen, that a read occurs just when the lock was taken blocking the reader until the lock is released at the end of the remove callback which then accessed *data that is already freed then. To actually fix this problem the hwmon core needs some adaption. Until this is implemented take the optimistic approach of assuming that all readers are gone after hwmon_device_unregister() and sysfs_remove_group() as most other drivers do. (And once the core implements that, taking the lock would deadlock.) So drop the lock, move the reset to after device unregistration to keep the device in a workable state until it's deregistered. Also add a error message in case the reset fails and return 0 anyhow. (Returning an error code, doesn't stop the platform device unregistration and only results in a little helpful error message before the devm cleanup handlers are called.)

After commit b6c02ef54913 ("bridge: Netlink interface fix."), br_fill_ifinfo() started to send an empty IFLA_AF_SPEC attribute when a bridge vlan dump is requested but an interface does not have any vlans configured. iproute2 ignores such an empty attribute since commit b262a9becbcb ("bridge: Fix output with empty vlan lists") but older iproute2 versions as well as other utilities have their output changed by the cited kernel commit, resulting in failed test cases. Regardless, emitting an empty attribute is pointless and inefficient. Avoid this change by canceling the attribute if no AF_SPEC data was added. Fixes: b6c02ef54913 ("bridge: Netlink interface fix.")

2022-07-26dmaengine: sh: rz-dmac: Add device_synchronize callbackBiju Das
Some on-chip peripheral modules(for eg:- rspi) on RZ/G2L SoC use the same signal for both interrupt and DMA transfer requests. The signal works as a DMA transfer request signal by setting DMARS, and subsequent interrupt requests to the interrupt controller are masked. We can re-enable the interrupt by clearing the DMARS. This patch adds device_synchronize callback for clearing DMARS and thereby allowing DMA consumers to switch to interrupt mode.

2022-07-26dmaengine: sprd: Cleanup in .remove() after pm_runtime_get_sync() failedUwe Kleine-König
It's not allowed to quit remove early without cleaning up completely. Otherwise this results in resource leaks that probably yield graver problems later. Here for example some tasklets might survive the lifetime of the sprd-dma device and access sdev which is freed after .remove() returns. As none of the device freeing requires an active device, just ignore the return value of pm_runtime_get_sync().

remove DRV_VERSION" Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: ==================== This is a cleanup series. The patches 1 to 8 get rid of any hardcoded strings and instead relies on the KBUILD_MODNAME macros to get the device name. Patch 9 replaces the ES58X_MODULE_NAME macro with KBUILD_MODNAME in etas_es58x. Finally, also in etas_es58x, patch 10 removes the DRV_VERSION so that the module uses the default behavior and advertise the kernel version instead of a custom version. * Changelog * v1 -> v2: * The patch for esd_usb contained some changes for ems_usb. * v1 assumed that KBUILD_MODNAME could only be used when the file basename and the module had the same name (e.g. vcan.c for the vcan.ko). The fact is that KBUILD_NAME extends to the module name and can thus be used even if the basename is different (e.g. slcan-core.c and slcan.ko) * Add patch #9: can: etas_es58x: replace ES58X_MODULE_NAME with KBUILD_MODNAME v1: https://lore.kernel.org/all/20220725153124.467061-1-mailhol.vincent@wanadoo.fr This series are the first 9 patches of: https://lore.kernel.org/linux-can/20220725133208.432176-1-mailhol.vincent@wanadoo.fr/T/ The initial intent of those 9 patches was to do so cleanup in order to implement ethtool_ops::get_drvinfo but this appeared to be useless: https://lore.kernel.org/linux-can/20220725140911.2djwxfrx3kdmjeuc@pengutronix.de/ Instead, those patch are send as a standalone series. ==================== Drop "[PATCH v2 03/10] can: slcan: use KBUILD_MODNAME and define pr_fmt to replace hardcoded names" to avoid conflicts with Dario Binacchi's work on the slcan driver.

2022-07-26dmaengine: tegra: Add terminate() for Tegra234Akhil R
In certain cases where the DMA client bus gets corrupted or if the end device ceases to send/receive data, DMA can wait indefinitely for the data to be received/sent. Attempting to terminate the transfer will put the DMA in pause flush mode and it remains there. The channel is irrecoverable once this pause times out in Tegra194 and earlier chips. Whereas, from Tegra234, it can be recovered by disabling the channel and reprograming it. Hence add a new terminate() function that ignores the outcome of dma_pause() so that terminate_all() can proceed to disable the channel.
