2018-07-09ARM: dts: BCM5301X: Make USB 3.0 PHY use MDIO PHY driverVivek Unune1-0/+4
Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which requires register range "ccb-mii" <0x18003000 0x1000>. This range overlaps with MDIO cmd and param registers (<0x18003000 0x8>). Essentially, the platform driver partly acts like a MDIO bus driver, hence to use of this register range. In some Northstar devices like Linksys EA9500, secondary switch is connected via external MDIO. The only way to access and configure the external switch is via MDIO bus. When we enable the MDIO bus in it's current state, the MDIO bus and any child buses fail to register because of the register range overlap. On Northstar, the USB 3.0 PHY is connected at address 0x10 on the internal MDIO bus. This change moves the usb3_phy node and makes it a child node of internal MDIO bus. Thanks to Rafał Miłecki's commit af850e14a7ae ("phy: bcm-ns-usb3: add MDIO driver using proper bus layer") the same USB 3.0 platform driver can now act as USB 3.0 PHY MDIO driver.

2018-05-07ARM: dts: BCM5301X: Relicense Buffalo files to the GPL 2.0+ / MITRafał Miłecki1-2/+1
This matches licensing used by other BCM5301X files and is preferred as: 1) GPL 2.0+ makes is clearly compatible with Linux kernel 2) MIT is also permissive but preferred over ISC These files were created and ever touched by a group of four people only: Felix, INAGAKI, Hauke and me.

2017-03-09ARM: dts: BCM5301X: Don't use nonexistent "default-off" LED triggerRafał Miłecki1-8/+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>
2017-01-18ARM: 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.

2016-10-19ARM: BCM5301X: Enable UART on Netgear R8000Rafał Miłecki1-1/+1
It was tested by LEDE users, all we need is to adjust clock frequency. While we're at it create a separated DTS include file to share code with other BCM4709 devices easier. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
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 Miłecki1-0/+5
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>
