* lantiq: fix sleep with spinlock held in xrx200 network driverAndrea Merello2017-07-202-6/+8
| | | | | | | | | | | | | | | | | | | | | | | In the xrx200_close() function we call napi_disable(), that could sleep, with priv->hw->chan[i].lock held. This could lead to deadlock and causes the kernel to complain. Look at the code I couldn't convince myself about why we need to protect that specific code part with the lock. IMHO there seems no reason to protect the refcount variables, because AFAIK ndo_close() and ndo_open() callbacks are already called with a semaphore held. Neither I could figure out why napi_disable() have to be called with that lock held. The only remaining code part for which I could guess the lock is useful for is ltq_dma_close() function call. This patch reduces the lock to the said function call, avoiding the sleep-with-spinlock-held situation Signed-off-by: Andrea Merello <andrea.merello@gmail.com> [fold into 0025-NET-MIPS-lantiq-adds-xrx200-net.patch, backport to kernel 4.4] Signed-off-by: Mathias Kresin <dev@kresin.me>
* treewide: populate boardname and model earlierMathias Kresin2017-07-151-0/+0
| | | | | | | | | | | | | For targets using the generic board detection and board specific settings in diag.sh, the board name is still unset at the time the set_state() provided by diag.sh is called by 10_indicate_preinit. Change the execution order to ensure the boardname is populated before required the first time. Do the target specific board detection as early as possible, directly followed by the generic one to allow a seamless switch to the generic function for populating /tmp/sysinfo/.

* lantiq: add Netgear DM200 supportThomas Nixon2017-07-074-0/+234
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Netgear DM200 is an inexpensive VDSL modem: CPU: VRX220 MIPS 34Kc 5.6 @ 500Mhz RAM: 64MiB Flash: 8MiB Ethernet: 1x100M DSL: VDSL2+, ADSL2+ reset button, 3x bi-color LEDs Serial port is 115200 baud, on the 4 pin header; pins from the bottom to top are GND, RX, TX. To upgrade from the vendor firmware, upload factory.img The DM200 bootloader supports flashing over TFTP; hold the reset button while powering on the device, and wait for the power light to start flashing green before releasing. The device is now listening on 192.168.0.1/24, and can be sent a factory.img or a netgear image with a TFTP put. Once the image is loaded, it will be written to the flash, and the device will reboot; this will take a few minutes. Thanks to Edward O'Callaghan and Baptiste Jonglez, who implemented their own ports for this device and provided valuable feedback. Signed-off-by: Thomas Nixon <tom@tomn.co.uk>

* lantiq: spi: double time out toleranceHauke Mehrtens2017-05-211-0/+37
| | | | | | | | | | | | | | | | | | | The generic SPI code calculates how long the issued transfer would take and adds 100ms in addition to the timeout as tolerance. On my 500 MHz Lantiq Mips SoC I am getting timeouts from the SPI like this when the system boots up: m25p80 spi32766.4: SPI transfer timed out blk_update_request: I/O error, dev mtdblock3, sector 2 SQUASHFS error: squashfs_read_data failed to read block 0x6e After increasing the tolerance for the timeout to 200ms I haven't seen these SPI transfer time outs any more. The Lantiq SPI driver in use here has an extra work queue in between, which gets triggered when the controller send the last word and the hardware FIFOs used for reading and writing are only 8 words long.

* lantiq: DGN3500: make switch LEDs blink on activityKevin Darbyshire-Bryant2017-04-251-0/+15
| | | | | | | | | | | | | | | | | Make switch port LEDs blink on activity as they do with stock firmware. The u-boot loader sets suitable values in the LED control register that unfortunately get blown away by the linux switch driver init. Restore that value by using driver 'initvals'. 0x0431 is the led control register, the value 0x0960. Each nybble represents each LED's mode (LED3,2,1,0) in this case OFF, 1000LINK+Activity, 100/10LINK+Activity, OFF. Only LED1&2 are physically present. Enabling the blinkenlights exposed the fact that an RRCP packet was being emitted by the switch on all ports every second. Further initvals copied from stock firmware's u-boot driver disabled this 'feature'. Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>

* lantiq: vr9 fxs support: fixed check of SMP state within vpe-mt.cStefan Koch2017-03-171-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | SMP state is generally affected by - CONFIG_SMP build-time kernel configuration option and - 'nosmp' runtime kernel commandline option The SMP state within vpe-mt.c is determined by CONFIG_SMP option. A runtime check is needed if VPE functionality should be used with a kernel image that supports SMP. This fix introduces a check for 'nosmp' command line option if CONFIG_SMP kernel configuration option is enabled. Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP (that activates CONFIG_SMP) is enabled within kernel configuration and the 'nosmp' command line argument is given to disable SMP at runtime. Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS. With this patch setting the 'nosmp' parameter is enough. In general, concurrent usage of FXS and SMP is incompatible and will cause kernel panics. Signed-off-by: Stefan Koch <stefan.koch10@gmail.com>

A runtime check is needed if VPE functionality should be used with a kernel image that supports SMP. This fix introduces a check for 'nosmp' command line option if CONFIG_SMP kernel configuration option is enabled. Note: This patch is needed to use lantiq FXS if CONFIG_MIPS_MT_SMP (that activates CONFIG_SMP) is enabled within kernel configuration and the 'nosmp' command line argument is given to disable SMP at runtime. Without this patch CONFIG_MIPS_MT_SMP must be disabled before using FXS. With this patch setting the 'nosmp' parameter is enough. In general, concurrent usage of FXS and SMP is incompatible and will cause kernel panics. Signed-off-by: Stefan Koch <stefan.koch10@gmail.com>
