2017-08-07ARM: dts: BCM5301X: Specify USB ports for USB LEDs of few devicesRafał Miłecki1-0/+3
This uses trigger-sources documented in commit 80dc6e1cd85fc ("dt-bindings: leds: document new trigger-sources property") to specify USB ports. Such an information can be used by operating system to setup LEDs behavior. I updated dts files for 7 devices I own and I was able to test.

2017-03-09ARM: dts: BCM5301X: Don't use nonexistent "default-off" LED triggerRafał Miłecki1-3/+0
Such a trigger doesn't exist in Linux and is not needed as LED is being turned off by default. This could cause errors in LEDs core code when trying to set default trigger. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
2017-01-19ARM: dts: BCM5301X: Specify all RAM by including an extra blockRafał Miłecki1-1/+2
The first 128 MiB of RAM can be accessed using an alias at address 0x0. In theory we could access whole RAM using 0x80000000 - 0xbfffffff range (up to 1 GiB) but it doesn't seem to work on Northstar. For some reason (hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff range can't be used. I reproduced this problem on: 1) Buffalo WZR-600DHP2 (BCM47081) 2) Netgear R6250 (BCM4708) 3) D-Link DIR-885L (BCM47094) So it seems we're forced to access first 128 MiB using alias at 0x0 and the rest using real base address + 128 MiB offset which is 0x88000000.

2017-01-19ARM: dts: BCM5301X: Enable UART by default for BCM4708(1), BCM4709(4) & BCM53012Rafał Miłecki1-4/+0
Every device tested so far got UART0 (at 0x18000300) working as serial console. It's most likely part of reference design and all vendors use it that way. It seems to be easier to enable it by default and just disable it if we ever see a device with different hardware design.

2016-06-01ARM: BCM5301X: Enable SPI-NOR on dual flash devicesRafał Miłecki1-0/+4
Commit 1b47b98acce2 ("ARM: BCM5301X: Add DT entry for SPI controller and NOR flash") enabled SPI-NOR device on routers using serial flash only. However there are also devices with two flash memories: 1) Small SPI attached flash used mostly for booting 2) Bigger NAND used mostly for storing firmware On such devices we still need SPI-NOR e.g. to access NVRAM data.

2016-04-13ARM: BCM5301X: Set vcc-gpio for USB controllers of few devicesRafał Miłecki1-11/+4
There are few devices that have USB power controlled using GPIO. Linux USB host driver (bcma-hcd) already supports this by reading vcc-gpio from DT. Set it properly for all known devices. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>

Add GPIO number which is needed to activate the USB power supply. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
2015-07-08ARM: BCM5301X: Enable UART0 on tested devicesRafał Miłecki1-10/+4
There are two possible UARTs so we have (both of) them disabled by default. Override uart0 status on devices that were verified to use it. In case of Netgear R6250 also drop an old (and invalid) overwrite. It doesn't have uart1 connected.
