2018-10-23net: stmmac: dwmac-sun8i: fix OF child-node lookupJohan Hovold1-2/+10
Use the new of_get_compatible_child() helper to lookup the mdio-internal child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the mdio-mux node). Fortunately, this was inadvertently balanced by a failure to drop the mdio-mux reference after lookup. While at it, also fix the related mdio-internal- and phy-node reference leaks.

2018-10-23net: socionext: Add dummy PHY register read in phy_write()Masahisa Kojima1-2/+16
There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E.

2018-10-23net: socionext: Stop PHY before resetting netsecMasahisa Kojima1-4/+15
In ndo_stop, driver resets the netsec ethernet controller IP. When the netsec IP is reset, HW running mode turns to NRM mode and driver has to wait until this mode transition completes. But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver" * tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (116 commits) gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip() gpio: Remove unused 'irqchip' argument to gpiochip_set_cascaded_irqchip() gpio: Drop parent irq assignment during cascade setup mmc: pwrseq_simple: Fix incorrect handling of GPIO bitmap gpio: fix SNPS_CREG kconfig dependency warning gpiolib: Initialize gdev field before is used gpio: fix kernel-doc after devres.c file rename gpio: fix doc string for devm_gpiochip_add_data() to not talk about irq_chip gpio: syscon: Fix possible NULL ptr usage gpiolib: Show correct direction from the beginning pinctrl: msm: Use init_valid_mask exported function gpiolib: Add init_valid_mask exported function GPIO: add single-register GPIO via CREG driver dt-bindings: Document the Synopsys GPIO via CREG bindings gpio: mockup: use device properties instead of platform_data gpio: Slightly more helpful debugfs gpio: omap: Remove set but not used variable 'dev' gpio: omap: drop omap_gpio_list Accept partial 'gpio-line-names' property. gpio: omap: get rid of the conditional PM runtime calls ...

Configure NIX RX flowkey algorithm configuration to support RSS (receive side scaling). Currently support for only L3/L4 2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added. HW supports upto 32 different flowkey algorithms which SW can define, this patch defines 9. NPC RX ACTION has to point to one of these flowkey indices for RSS to work. The configuration is dependent on NPC parse result's layer info.

L3/L4 and L4 CSUM validation will be enabled by PF/VF drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox i.e 'nix_lf_alloc_req->rx_cfg' Also enable setting of NPC_RESULT_S[L2B] when an outer L2 broadcast address is detected. This will help in installing NPC MCAM rules for broadcast packets. Signed-off-by: Sunil Goutham <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2018-10-22octeontx2-af: Broadcast packet replication supportSunil Goutham2-0/+220
Allocate memory for mcast/bcast/mirror replication entry contexts, replication buffers (used by HW) and config HW with corresponding memory bases. Added support for installing MCEs via NIX AQ mbox. For now support is restricted to broadcast pkt replication, hence MCE table size and number of replication buffers allocated are less. Each CGX LMAC mapped RVU PF is assigned a MCE table of size 'num VFs of that PF + PF'. Signed-off-by: Sunil Goutham <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-22octeontx2-af: Config pkind for CGX mapped PFsGeetha sowjanya7-2/+90
For each CGX LMAC that is mapped to a RVU PF, allocate a pkind and config the same in CGX. For a received packet at CGX LMAC interface this pkind is used by NPC block to start parsing of packet.

2018-10-22octeontx2-af: Config NPC KPU engines with parser profileSunil Goutham6-1/+385
This patch configures all 16 KPUs and iKPU (pkinds) with the KPU parser profile defined in npc_profile.h. Each KPU engine has a 128 entry CAM, only CAM entries which are listed in the profile are enabled and rest are left disabled. Also - Memory is allocated for pkind's bitmap and PFFUNC, interface channel mapping. - Added all CSR offsets of NPC HW block. Signed-off-by: Sunil Goutham <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2018-10-22octeontx2-af: Add NPC KPU profileHao Zheng2-0/+5852
NPC block is responsible for parsing and forwarding packets to different NIXLFs. NPC has 16 KPU engines (Kangaroo parse engine) and one iKPU which represents pkinds. Each physical port either CGX/LBK is assigned a pkind and upon receiving a packet HW takes that port's pkind and starts parsing as per the KPU engines config. This patch adds header files which contain configuration profile/array for each of the iKPU and 16 KPU engines.

2018-10-22octeontx2-af: NIX Tx scheduler queue config supportSunil Goutham5-5/+199
This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured.

2018-10-22octeontx2-af: NIX Tx scheduler queues alloc/freeSunil Goutham4-4/+265
Added support for a PF/VF to allocate or free NIX transmit scheduler queues via mbox. For setting up pkt transmission priorities between queues, the scheduler queues have to be contiguous w.r.t their HW indices. So both contiguous and non-contiguous allocations are supported. Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues allocated to sending PFFUNC (PF/VF) will be freed. Selective free is not supported.
