* ramips: rename pwm kernel moduleMathias Kresin2018-04-081-5/+5
| | | | | | | | | | | | | | With kernel 4.14 the OpenWrt specific module name collides with the upstream added module for Mediatek ARM Socs. During addition of preliminary support for kernel 4.14, the config symbol used by the out of tree driver was already renamed but the ramips kernel package wasn't updated. Fix the build error by updating the config and kernel module name for the kernel package. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: add support for Zorlik ZL5900V2Vianney le Clément de Saint-Marcq2018-04-086-1/+109
| | | | | | | | | | | | | | | | | | | | | | | | The Zorlik ZL5900V2 is an unbranded clone of HAME MPR-A1/2. It is marketed as "3G Wi-Fi Router". Only the PCB has the model name "ZL5900V2" printed on it. Specifications: - Ralink RT5350F (360 MHz) - 32 MB RAM - 8 MB Flash - 802.11bgn 1T1R - 1x 10/100 Mbps Ethernet - 1x USB 2.0 (Type-A) - 5200 mAh battery The ramdisk image (not the squashfs sysupgrade image) can be flashed through the web interface (named "GoAhead") of the factory firmware. However, as the factory firmware does not cleanly unmount the rootfs before flashing, the device may hang instead of rebooting after successful write. Power cycling the device gets you in OpenWrt where the squashfs image may be flashed through normal sysupgrade procedure. Signed-off-by: Vianney le Clément de Saint-Marcq <code@quartic.eu>

* ramips: add dwr-512 jboot firmware configurationGiuseppe Lippolis2018-04-085-15/+19
| | | | | | | | | | | | | | | | | | | | | The previous fw version require the replacement of the stock bootloader with u-boot. This prevent an easy stock restore of the original fw. Now a proper fw util has been developed to manage the stock jboot bootloader. Therefore make sense have a fw image for the stock bootloader. The old fw configuration (u-boot) is not compatible with the new one and will not be supported anymore. So at the end 2 image can be generated: 1) factory image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin 2) sysupgrade image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-sysupgrade.bin Signed-off-by: Giuseppe Lippolis <giu.lippolis@gmail.com>
* ramips: fix usbphy DT nodes on linux 4.14Vianney le Clément de Saint-Marcq2018-04-077-25/+34
| | | | | | | | | | | | | | The Ralink USB PHY driver merged into mainline has a slightly different device tree binding than the patch that was used with linux 4.9. The new driver requires a `ralink,sysctl` node pointing to the `syscon` node. This patch also sets `#phy-cells` to 0, as recommended by the mainline documentation [1].

* ramips: mtk-mmc: don't advertise highmem support.NeilBrown2018-04-052-0/+2
| | | | | | | | | | | | | | | | of_dma_configure() sets a default ->dma_mask of DMA_BIT_MASK(32), claiming devices can DMA from the full 32bit address space. The mtk-mmc driver does not support access to highmem pages, so it is really limited to the bottom 512M (actually 448M due to 64M of IO space). Setting ->dma_mask to NULL causes mmc_setup_queue() to fall-back to using BLK_BOUNCE_HIGH to tell the block layer to use a bounce-buffer for any highmem pages requiring IO.

* ramips: mt7620: eMMC: stop invalid memory access if only one device is definedAndré Draszik2018-04-042-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pdev->id is -1 when only one device exists, and is used: * as an index into drv_mode[] to determine whether to use PIO or DMA mode (via host->id) * as an index into msdc_6575_host[], to store the mmc_priv() data. Obviously, -1 is not a valid index in either case, causing us to read invalid memory, and memory corruption, respectively. The invalid memory read is causing non-deterministic behaviour, in particular in the v4.4 kernel it still picked DMA mode, but in the v4.9 it now always picks PIO mode. Also, PIO mode doesn't work, causing the following: / # echo 3 > /proc/sys/vm/drop_caches [ 3845.249237] sh (128): drop_caches: 3 / # /root/usr/lib/libc.so [ 3846.096070] do_page_fault(): sending SIGSEGV to libc.so for invalid read access from 7f9cb5a0 [ 3846.104758] epc = 779b0ea4 in libc.so[7792f000+c3000] [ 3846.109907] ra = 779a8004 in libc.so[7792f000+c3000] Segmentation fault / # /root/usr/lib/libc.so musl libc (mipsel-sf) Version 1.1.16-git-40-g54807d47 Dynamic Program Loader Usage: /root/usr/lib/libc.so [options] [--] pathname [args] (i.e. initial page-in of any binary causes a segfault, subsequent access works.)

Therefore 5Ghz won' work. Flash instruction: The only way to flash LEDE image in TL-WR902AC v3 is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.0.66/24 and tftp server. 2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with the LAN port, press the reset button, power up the router and keep button pressed for around 6-7 seconds, until device starts downloading the file. 4. Router will download file from server, write it to flash and reboot.

* ramips: fix spurious IRQ7 events when using perf on 4.14Felix Fietkau2018-02-271-0/+15
| | | | | | | | | | | | | Upstream handling of MIPS CPU IRQs is rather hackish and the interrupts are being enabled unconditionally in various places because of legacy code. Performance counter events are routed both through the GIC and through legacy CPU IRQ7 events, causing spurious interrupts. Fix this by disabling IRQ7 when trying to access the performance counter IRQ. Signed-off-by: Felix Fietkau <nbd@nbd.name>
