* ramips: fix network setup for various NETGEAR boardsDavid Bauer2019-09-071-11/+6
| | | | | | | | | | | | | | | | | There are currently the following issues present for the Netgear R6220, R6350 and WNDR3700 v5: - LAN and WAN MAC-addresses are inverted - WAN MAC-address is off. It are +2 compared to the LAN MAC-address (R6350 only) - Switchport order is inverted in LuCi This commit fixes both these issues by assigning correct MAC-addresses to LAN and WAN interfaces and defining the switchports with the correct labels.

| | | | | | | | | | This commit switches the default trigger for the WiFi LED from a netdev trigger on "wlan0" to a wireless-phy based trigger. THis allows the LED to work, even when the wireless interface is not named "wlan0" without modifiying the LED settings.

* ramips: disable badblock shifting for MT7621 NANDDavid Bauer2019-09-071-1/+1
| | | | | | | | | | | | | | | | | | The MediaTek MT7621 NAND driver currently intransparently shifts NAND pages when a block is marked as bad. Because of this, offsets for e.g. caldata and MAC-addresses seem to be off. This is, howeer, not a task for the mtd NAND driver, as the flash translation layer is tasked with this. This patch disables this badblock shifting. This fix was originally proposed by Jo-Philipp Wich at https://bugs.openwrt.org/index.php?do=details&task_id=1926 Fixes FS#1926 ("MTD partition offset not correctly mapped when bad eraseblocks present") Signed-off-by: David Bauer <mail@david-bauer.net> (cherry picked from commit 527832e54bf3bc4d699a145ae66f34230246f0a9)

* apm821xx: fix bogus key-presses on bootChristian Lamparter2019-09-041-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | "There are often transient line events when the system is powered up and initialized and it is often necessary for the gpio_chip driver to clear any interrupt flags in hardware before setting up the gpio chip, especially the irqchip portions of it." <http://lists.infradead.org/pipermail/openwrt-devel/2019-June/017630.html> This patch adds a fix for the APM821XX's interrupt controller to clear any bogus pending toggled interrupts that happens on various APM821XX boards on boot. The patch also changes the debouce-interval from the default 5ms debounce interval to 60ms all around. The default setting caused on occasions that the button state became stuck in a pressed state, even though the button was released.

* ar71xx: WNR2200: remove redundant GPIO for WLAN LEDMichal Cieslakiewicz2019-08-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Without this patch, an extra entry appears for AR9287 GPIO that duplicates WLAN LED but in fact drives nothing: gpiochip1: GPIOs 502-511, ath9k-phy0: gpio-502 ( |netgear:blue:wlan ) out hi gpio-503 ( |netgear:amber:test ) out hi gpio-504 ( |netgear:green:power ) out lo gpio-505 ( |rfkill ) in hi gpio-507 ( |wps ) in hi gpio-508 ( |reset ) in hi gpio-510 ( |ath9k-phy0 ) out hi <===! The pin pointed above is default LED GPIO (8) for AR9287. For WNR2200 it is not connected anywhere - pin 0 drives blue WLAN LED instead - but initialization code is missing that information. This fix calls ap9x_pci_setup_wmac_led_pin() function at device setup, forcing WLAN LED pin to be 0 and removing redundant entry. Signed-off-by: Michal Cieslakiewicz <michal.cieslakiewicz@wp.pl>

| | | | | | | | | | | | | The command line enforced by the kernel is harmful, we want to use the command line passed from the device tree. This is especially important for the SQ201, Teltonika RUT and WBD111 which has a console set to 115200n8 and not 19200n8 like all the others, so their consoles will be confusingly changing baudrate between boot loader and kernel.

* lantiq: unify Fritz!Box LED mappingsDavid Bauer2019-08-154-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit unifies the LED mapping of the AVM Fritz!Box routers, which have a combined Power/DSL LED. With the stock firmware, the Power LED has the following characteristics: - Blink when DSL sync is being established - Solid when DSL sync is present We can't completely resemble this behavior in OpenWrt. Currently, the Power LED is completely off, when DSL sync is missing. This is not really helpful, as a user might have the impression, that he bricked his device. Instead, map the Info-LED to the state of the DSL connection. There is no consistent behavior for the Info-LED in the stock firmware, as the user can set it's function by himself. The DSL connection state is one possible option for the Info LED there. Also use the red Power LED to indicate a running upgrade, in case the board has a two-color Power LED.

* ar71xx/ath79: ag71xx: init rings with GFP_KERNELKoen Vandeputte2019-08-091-1/+1
| | | | | | | | | | | | | | | Upstream commit 246902bdf562d45ea3475fac64c93048a7a39f01 Which contains following explanation: -- There is no need to use GFP_ATOMIC here, GFP_KERNEL should be enough. The 'kcalloc()' just a few lines above, already uses GFP_KERNEL. -- Looking at the code, all other descriptors also use plain GFP_KERNEL Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
