* treewide: convert gpio-export to platform driverRené van Dorst2018-08-041-7/+4
| | | | | | | | | | | | Without this patch you will get an error "gpio-export probe deferral not supported" when you try to export i2c expander gpio pins. gpio-export is probed long before i2c-bus and i2c expander are created and it doesn't retry it so none pins are exported.

* ath79: really fix TP-Link Archer C7 v2 MAC addressMathias Kresin2018-08-042-2/+1
| | | | | | | | | | | | | | | | | | | | Revert 290c54473ead ("ath79: fix TP-Link Archer C7 v2 wlan1 MAC address") which obviously aims to have a distinct MAC address per interface. Unfortunally it doesn't match what is used by the stock firmware and we shouldn'z use MAC Adresses not reserverd for/assigned to a particular board. The correct MAC adress increments for this board are: wlan0 (5GHz) : -1 wlan1 (2.4GHz) : 0 eth1 (LAN) : 0 eth0 (WAN) : 1 Fixes: FS#408 Signed-off-by: Mathias Kresin <dev@kresin.me>

* ath79: Forward port support for CR3000Daniel F. Dickinson2018-08-014-3/+194
| | | | | | | | | | | | | | | | | | | | | | | | The PowerCloud Systems CR3000 was a cloud-managed CPE for a now defunct NaaS offering. It was previously supported under the ar71xx branch and this forward ports that support with some notable differences: 1) Since reverting to stock firmware is now irrelevant there is is only a single openwrt image generated which uses the entire flash rather than preserving PowerCloud-specific partitions that are unneeded to openwrt-- those partitions will be erased and used by the openwrt image. 2) Rather than use a non-standard probe order for the ethernet devices, this image uses a set of 'ip link set ethX name ethY' commands very early in preinit (before the network is used at all), in order to have the the switch and Wan use the same ethernet names as in previous images. 3) /etc/config/wireless will need to be regenerated as the path to the wireless device has changed due to differences in ath79 DT for ar93x compared to ar71xx images. 4) eth0 is wan and eth1 is lan (switch) Signed-off-by: Daniel F.

* ath79: fix irq assignment for pci-ar71xx driverMatt Merhar2018-07-301-3/+7
| | | | | | | | | | | | | | | | | | In the new DT-based pci-ar71xx driver, ar71xx_pci_irq_init() was being called before populating the PCI controller's device_node struct member. This led to no IRQ being assigned to connected PCI devices (e.g. ath9k cards) and caused them to be non-functional aside from simply being detected. The previous errors encountered in dmesg were: "irq: no irq domain found for /ahb/apb/pcie-controller@180c0000 !". /proc/interrupts listed an IRQ of 0 for the cards. While this has been only been tested on a yet-to-be-merged RouterStation Pro target, it should also fix the broken wifi people have reported for the ath79 WNDR3800 target.

Since the builtin switch is an independent device, setting mac address of gmac1 to builtin switch isn't a good idea and this makes it impossilbe to split builtin switch apart as an independent platform device.

* ath79: Port PowerCloud Systems CAP324 supportDaniel F. Dickinson2018-07-305-0/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CAP324 was an AP for a NaaS offering that is now defunct. While previously supported in the ar71xx arch, there were some errata (to be fixed shortly). Notable differences from ar71xx support: 1) The method of getting the ath9k firmware for the PCIe 2ghz wifi has changed (due to changes in how the arch handles this), since this device doesn't use the EEPROM except to get the MAC address of the wifi. 2) /etc/config/wireless will need to be regenerated as the path(s) to the wireless device(s) have changed. 3) ath79 OpenWrt firmware no longer supports build an image that allows reverting to stock firmware (as the cloud service no longer exists, the stock firmware is useless), instead using all of the flash for image and overlay (less u-boot/env and art). 4) Initial network config treats the ethernet port as a Lan port with the standard default address (192.168.1.1 unless changed in .config --e.g. via menuconfig) instead of using DHCP (this was the default for the stock firmware, however for openwrt use this is rather confusion and counter-productive as the user has a harder time finding the device on the network.

* ath79: Port PowerCloud Systems CR5000 supportDaniel F. Dickinson2018-07-304-0/+246
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add ath79 arch support for PowerCloud Systems CR5000. Previously supported under ar71xx (however there are some errors in that support; to be fixed shortly). Info: * This board is based on the Atheros DB120 reference design, but doesn't use the on-board switch. Instead it attachs GMAC0 to an AR8327 switch. * It only uses GMAC0 and the WAN is simply a VLAN in the stock firmware. * It has 64MB RAM and 8MB flash. * In the dts version we get rid of using 'open-drain' for the AR8327 LED controls. * As with the platform data version we disable JTAG as this conflicts with one of the pair of GPIO's required for the power/status LED (GPIO2 and GPIO4 are used for this LED). * The pcie card wifi has an EEPROM but gets it's MAC address from the ART partition. * The SoC wifi (2.4 GHz) is all from the ART. * The USB is support comes from the SoC. NB. This is actually an AR9342 rather than AR9344 but we use the 9344 definitions because there are no relevant differences for this board. NB: Building only images that don't support reverting to the old cloud-based firmware as the Skydog cloud service for the CR5000 no longer exists. Signed-off-by: Daniel F.

* kernel: only optimized for size if small_flashMathias Kresin2018-07-121-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me>

NOTE: The U-Boot won't boot with the serial attached. Boot the device without serial attached and attach it after 3 seconds. Tested and working: - Ethernet - 2.4 GHz WiFi - 5 GHz WiFi - TFTP boot from ramdisk image - Installation via ramdisk image - OpenWRT sysupgrade - Buttons - LEDs Installation seems to be possible only through booting an OpenWRT ramdisk image. Hold down the reset button while powering on the device. It will load a ramdisk image named 'raccoon-uImage-initramfs-lzma.bin' from 192.168.100.8. Note: depending on the present software, the device might also try to pull a file called 'raccoon-uimage-factory'. Only the name differs, it is still used as a ramdisk image. Wait for the ramdisk image to boot. OpenWRT can be written to the flash via sysupgrade or mtd. Due to the flip-flop bootloader which we not (yet) support, you need to set the partition the bootloader is selecting. It is possible from the initramfs image with > fw_setenv bootcmd run bootcmd_1 Afterwards you can reboot the device. Signed-off-by: David Bauer <mail@david-bauer.net>
