* ar71xx: rb91x: fix ethernet packet loss issuesGabor Juhos2014-04-131-0/+19
| | | | | | | | | | | | | | The RB91x boards are suffering from ethernet packet loss after a cold boot. The cause of the problem is that the AR8035 PHYs requires special register settings to work reliably on these boards. Enable the RGMII TX, RX delays and disable SmartEE functionality of the AR8035 PHYs. Also enable the RXD delay in the ETH_CFG register to fix the issue.

* ar71xx: rb91x: add SPI device for the serial shift registerGabor Juhos2014-02-231-2/+62
| | | | | | | | | | | | | The RB91x boards are using a serial shift register connected to the SPI bus to drive some of the LEDs. Rework the board setup code to register a SPI device for that. This makes it possible to use the 'spi-74x164' driver to control the device.
