2022-01-05net: gemini: allow any RGMII interface modeRussell King (Oracle)
The four RGMII interface modes take care of the required RGMII delay configuration at the PHY and should not be limited by the network MAC driver. Sadly, gemini was only permitting RGMII mode with no delays, which would require the required delay to be inserted via PCB tracking or by the MAC. However, there are designs that require the PHY to add the delay, which is impossible without Gemini permitting the other three PHY interface modes. Fix the driver to allow these.

2022-01-05net: phy: marvell: configure RGMII delays for 88E1118Russell King (Oracle)
Corentin Labbe reports that the SSI 1328 does not work when allowing the PHY to operate at gigabit speeds, but does work with the generic PHY driver. This appears to be because m88e1118_config_init() writes a fixed value to the MSCR register, claiming that this is to enable 1G speeds. However, this always sets bits 4 and 5, enabling RGMII transmit and receive delays. The suspicion is that the original board this was added for required the delays to make 1G speeds work. Add the necessary configuration for RGMII delays for the 88E1118 to bring this into line with the requirements for RGMII support, and thus make the SSI 1328 work. Corentin Labbe has tested this on gemini-ssi1328 and gemini-ns2502.

2022-01-05mlxsw: pci: Avoid flow control for EMAD packetsDanielle Ratson
Locally generated packets ingress the device through its CPU port. When the CPU port is congested and there are not enough credits in its headroom buffer, packets can be dropped. While this might be acceptable for data packets that traverse the network, configuration packets exchanged between the host and the device (EMADs) should not be subjected to this flow control. The "sdq_lp" bit in the SDQ (Send Descriptor Queue) context allows the host to instruct the device to treat packets sent on this queue as "local processing" and always process them, regardless of the state of the CPU port's headroom. Add the definition of this bit and set it for the dedicated SDQ reserved for the transmission of EMAD packets. This makes the "local processing" bit in the WQE (Work Queue Element) redundant, so clear it.

Currently PF and VF use two sets of command code for modules to interact with firmware. These codes values are same espect the macro names. It is redundent to keep two sets of command code for same functions between PF and VF. So this patch firstly creates a unified command code for PF and VF module. We keep the macro name same with the PF command code name to avoid too many meaningless modifications. Secondly the new common command codes are used to replace the old ones in VF and deletes the old ones. Signed-off-by: Jie Wang <wangjie125@huawei.com> Signed-off-by: David S.

2022-01-05can: netlink: report the CAN controller mode supported flagsVincent Mailhol
Currently, the CAN netlink interface provides no easy ways to check the capabilities of a given controller. The only method from the command line is to try each CAN_CTRLMODE_* individually to check whether the netlink interface returns an -EOPNOTSUPP error or not (alternatively, one may find it easier to directly check the source code of the driver instead...) This patch introduces a method for the user to check both the supported and the static capabilities. The proposed method introduces a new IFLA nest: IFLA_CAN_CTRLMODE_EXT which extends the current IFLA_CAN_CTRLMODE. This is done to guaranty a full forward and backward compatibility between the kernel and the user land applications. The IFLA_CAN_CTRLMODE_EXT nest contains one single entry: IFLA_CAN_CTRLMODE_SUPPORTED. Because this entry is only used in one direction: kernel to userland, no new struct nla_policy are introduced. Below table explains how IFLA_CAN_CTRLMODE_SUPPORTED (hereafter: "supported") and can_ctrlmode::flags (hereafter: "flags") allow us to identify both the supported and the static capabilities, when masked with any of the CAN_CTRLMODE_* bit flags: supported & flags & Controller capabilities CAN_CTRLMODE_* CAN_CTRLMODE_* ----------------------------------------------------------------------- false false Feature not supported (always disabled) false true Static feature (always enabled) true false Feature supported but disabled true true Feature supported and enabled Link: https://lore.kernel.org/all/20211213160226.56219-5-mailhol.vincent@wanadoo.fr Signed-off-by: Vincent Mailhol <mailhol.vincent@wanadoo.fr> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
2022-01-05can: dev: add sanity check in can_set_static_ctrlmode()Vincent Mailhol
Previous patch removed can_priv::ctrlmode_static to replace it with can_get_static_ctrlmode(). A condition sine qua non for this to work is that the controller static modes should never be set in can_priv::ctrlmode_supported (c.f. the comment on can_priv::ctrlmode_supported which states that it is for "options that can be *modified* by netlink"). Also, this condition is already correctly fulfilled by all existing drivers which rely on the ctrlmode_static feature. Nonetheless, we added an extra safeguard in can_set_static_ctrlmode() to return an error value and to warn the developer who would be adventurous enough to set to static a given feature that is already set to supported. The drivers which rely on the static controller mode are then updated to check the return value of can_set_static_ctrlmode().

2022-01-05can: do not increase tx_bytes statistics for RTR framesVincent Mailhol
The actual payload length of the CAN Remote Transmission Request (RTR) frames is always 0, i.e. no payload is transmitted on the wire. However, those RTR frames still use the DLC to indicate the length of the requested frame. As such, net_device_stats::tx_bytes should not be increased when sending RTR frames. The function can_get_echo_skb() already returns the correct length, even for RTR frames (c.f. [1]). However, for historical reasons, the drivers do not use can_get_echo_skb()'s return value and instead, most of them store a temporary length (or dlc) in some local structure or array. Using the return value of can_get_echo_skb() solves the issue. After doing this, such length/dlc fields become unused and so this patch does the adequate cleaning when needed. This patch fixes all the CAN drivers. Finally, can_get_echo_skb() is decorated with the __must_check attribute in order to force future drivers to correctly use its return value (else the compiler would emit a warning).

The CAN error message frames (i.e. error skb) are an interface specific to socket CAN. The payload of the CAN error message frames does not correspond to any actual data sent on the wire. Only an error flag and a delimiter are transmitted when an error occurs (c.f. ISO 11898-1 section 10.4.4.2 "Error flag"). For this reason, it makes no sense to increment the tx_packets and tx_bytes fields of struct net_device_stats when sending an error message frame because no actual payload will be transmitted on the wire.

2022-01-05can: etas_es58x: es58x_init_netdev: populate net_device::dev_portVincent Mailhol
The field dev_port of struct net_device indicates the port number of a network device [1]. This patch populates this field. This field can be helpful to distinguish between the two network interfaces of a dual channel device (i.e. ES581.4 or ES582.1). Indeed, at the moment, all the network interfaces of a same device share the same static udev attributes c.f. output of: | udevadm info --attribute-walk /sys/class/net/canX The dev_port attribute can then be used to write some udev rules to, for example, assign a permanent name to each network interface based on the serial/dev_port pair (which is convenient when you have a test bench with several CAN devices connected simultaneously and wish to keep consistent interface names upon reboot).

2022-01-05can: ti_hecc: ti_hecc_probe(): use platform_get_irq() to get the interruptLad Prabhakar
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().

2022-01-04Revert "net: wwan: iosm: Keep device at D0 for s2idle case"M Chetan Kumar
Depending on BIOS configuration IOSM driver exchanges protocol required for putting device into D3L2 or D3L1.2. ipc_pcie_suspend_s2idle() is implemented to put device to D3L1.2. This patch forces PCI core know this device should stay at D0. - pci_save_state()is expensive since it does a lot of slow PCI config reads. The reported issue is not observed on x86 platform. The supurios wake on AMD platform needs to be futher debugged with orignal patch submitter [1]. Also the impact of adding pci_save_state() needs to be assessed by testing it on other platforms. This reverts commit f4dd5174e273("net: wwan: iosm: Keep device at D0 for s2idle case").

2022-01-04net: lantiq_xrx200: add ingress SG DMA supportAleksander Jan Bajkowski
This patch adds support for scatter gather DMA. DMA in PMAC splits the packet into several buffers when the MTU on the CPU port is less than the MTU of the switch. The first buffer starts at an offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the offset. Thanks to this patch, the user can still connect to the device in such a situation. For normal configurations, the patch has no effect on performance. Signed-off-by: Aleksander Jan Bajkowski <olek2@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

Add support for external timestamp and periodic signal output. TJA1103 have one periodic signal and one external time stamp signal that can be multiplexed on all 11 gpio pins. The periodic signal can be only enabled or disabled. Have no start time and if is enabled will be generated with a period of one second in sync with the LTC seconds counter. The phase change is possible only with a half of a second. The external timestamp signal has no interrupt and no valid bit and that's why the timestamps are handled by polling in .do_aux_work.

Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason.
