* ipq40xx: remove support for kernel 4.19Adrian Schmutzler2020-10-191-225/+0
| | | | | | | | | | The target uses 5.4 as default kernel since 03/2020. Kernel 4.19 support is not really maintained anymore, it does not seem to be needed, and removing it will make upcoming driver updates easier. Thus, remove it. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ipq40xx: mdio: remove support for phy-reset-gpioDENG Qingfang2019-11-071-65/+2
| | | | | | | | | | | | | Commit 6f6c00cfc95f ("ipq40xx: Add support for Unielec U4019") has introduced support for `phy-reset-gpio` DT property, which isn't needed as the MDIO already supports `reset-gpios`[1] which could be used instead. 1. https://elixir.bootlin.com/linux/v4.19.81/source/Documentation/devicetree/bindings/net/mdio.txt Ref: PR#2511 Signed-off-by: DENG Qingfang <dengqf6@mail2.sysu.edu.cn> [commit title and description facelift] Signed-off-by: Petr Štetiar <ynezz@true.cz>

* ipq40xx: fix ethernet probe abort on missing phy-resetDavid Bauer2019-10-231-1/+1
| | | | | | | This commit completely fixes the abortion of the ipq40xx ethernet driver probe in case no phy-reset is defined. Signed-off-by: David Bauer <mail@david-bauer.net>

* ipq40xx: Add support for Unielec U4019Kristian Evensen2019-10-211-4/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the 32MB storage/512MB RAM version of the U4019 IPQ4019-based board from Unielec. The board has the following specifications: * Qualcomm IPQ4019 (running at 717MHz) * 512MB DDR3 RAM (optional 256MB/1GB) * 32MB SPI NOR (optional 8/16MB or NAND) * Five gigabit ports (Qualcomm QCA8075) * 1x 2.4 GHz wifi (QCA4019 hw1.0) * 1x 5 Ghz wifi (QCA4019 hw1.0) * 1x mini-PCIe slot (only USB-pins connected) * 1x SIM slot (mini-SIM) * 1x USB2.0 port * 1x button * 1x controllable LED * 1x micro SD-card reader Working: * Ethernet * Wifi * USB-port * mini-PCIe slot + SIM slot * Button * Sysupgrade Not working: * SD card slot (no upstream support) Installation instructions: In order to install OpenWRT on the U4019, you need to go via the initramfs-image. The installation steps are as follows: * Connect to board via serial (header exposed and clearly marked). * Interrupt bootloader by pressing a button. * Copy the initramfs-image to your tftp folder, call the file C0A80079.img. * Give the network interface connected to the U4019 the address 192.168.0.156/24. * Start your tftp-server and run tftpboot on the board. * Run bootm when the file has been transferred, to boot OpenWRT. * Once OpenWRT has booted, copy the sysupgrade-image to the device and run sysupgrade to install OpenWRT on the U4019. Notes: - Since IPQ4019 has been moved to 4.19, I have not added support for kernel 4.14. - There is a bug with hardware encryption on IPQ4019, causing poor performance with TCP and ipsec (see for example FS#2355). In order to improve performance, I have disabled hardware encryption in the DTS. We can enable hw. enc. once/if bug is fixed. - In order for Ethernet to work, the phy has to be reset by setting gpio 47 low/high. Adding support for phy reset via gpio required patching the mdio-driver, and the code added comes from the vendor driver. I do not know if patching the driver is an acceptable approach or not. v1->v2: * Do not use wildcard as identifier in the board.d-scripts (thanks Adrian Schmutzler).

* ipq40xx: remove redundant PHY_POLL set codeChristian Lamparter2019-08-021-6/+1
| | | | | | | | The [devm_]mdiobus_alloc[_size()] functions are creating the array of interrupt numbers as well as initializing them to POLLING. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
* ipq40xx: decouple mdio-ipq40xx and ar40xxChristian Lamparter2019-08-021-0/+230
This makes it possible to delete the ar40xx driver in the future by just removing the file. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
