2019-07-22ARM: dts: sunxi: Switch from phy to phy-handleMaxime Ripard1-1/+1
The phy device tree property has been deprecated in favor of phy-handle, let's replace it. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
2019-04-04ARM: dts: sunxi: Remove pinctrl groups setting biasMaxime Ripard1-9/+1
So far we've enabled pull-up and pull-down resistors on GPIOs using a pinctrl node. Now that the GPIO binding allows for a flag to declare this, let's switch to it. This brings us closer to removing all the GPIO pinctrl nodes, which will in turn allow us to switch the pinctrl strict mode on.

2019-03-25ARM: sunxi: Fix the USB PHY ID detect GPIO propertiesMaxime Ripard1-1/+1
While the USB PHY Device Tree mandates that the name of the ID detect pin should be usb0_id_det-gpios, a significant number of device tree use usb0_id_det-gpio instead. This was functional because the GPIO framework falls back to the gpio suffix that is legacy, but we should fix this.

2018-02-13ARM: dts: sunxi: Switch MMC nodes away from cd-inverted propertyTuomas Tynkkynen1-2/+1
Using the cd-inverted property is not useful when GPIOs are used as card detects since the polarity can be specified with the usual GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for U-Boot developers, so migrate all sunxi boards away from cd-inverted.

2017-10-13ARM: dts: sun4i: Remove underscores from nodes namesMaxime Ripard1-2/+2
Some GPIO pinctrl nodes cannot be easily removed, because they would also change the pin configuration, for example to add a pull resistor or change the current delivered by the pin. Those nodes still have underscores and unit-addresses in their node names in our DTs, so adjust their name to remove the warnings. Use that occasion to also fix some poorly chosen node-names.

2017-10-13ARM: dts: sun4i: Provide default muxing for relevant controllersMaxime Ripard1-8/+0
The I2C's, MMC0 and EMAC controllers have only one muxing option in the SoC. In such a case, we can just move the muxing into the DTSI, and remove it from the DTS. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2017-10-13ARM: dts: sun4i: Change pinctrl nodes to avoid warningMaxime Ripard1-8/+8
All our pinctrl nodes were using a node name convention with a unit-address to differentiate the different muxing options. However, since those nodes didn't have a reg property, they were generating warnings in DTC. In order to accomodate for this, convert the old nodes to the syntax we've been using for the new SoCs, including removing the letter suffix of the node labels to the bank of those pins to make things more readable.

2015-05-10ARM: sunxi: dt: Split the SPI pinctrl groupsMaxime Ripard1-1/+2
The pinctrl groups for SPI until now were also adding the chip selects in the SPI pinctrl group. This was causing a few issues, since a board was forced to use a random number of chipselects, even though it might use one of these chip selects for another pin. The number of chipselects defined was also not the same from one group to another because of different needs at the time these groups have been introduced, resulting in no clear view from the board DTS on what exactly is being muxed, which even might change in the future. Solve this by creating different pinctrl groups for the chipselects and the standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.

2015-01-21ARM: dts: sun4i: cubieboard: add axp209 regulator nodesChen-Yu Tsai1-4/+31
This patch adds the regulator nodes for the axp209 by including the axp209 dtsi. As the inputs of these regulators are from the axp209's PS output, which is basically just a mux over the 2 inputs, it is considered to be unregulated. Thus we do not provide input supply properties for them. The regulator names and constraints are based on the board schematics and the SoC datasheet. DCDC2 is used as the cpu power supply. This patch also references it from the cpu node. Also get rid of axp209 properties already set in axp209.dtsi.

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...
