| | | | | | Backported from Code Aurora QSDK Signed-off-by: Vittorio Gambaletta <openwrt@vittgam.net>
* ar71xx: convert mikrotik routerboard support to UBIFelix Fietkau2017-02-013-3/+3
| | | | | | | | | | Remove the wget2nand script, drop the need for manual installation, use sysupgrade instead. There are now two different NAND images, one for 64 MiB flashes, the other for >= 128 MiB Signed-off-by: Felix Fietkau <nbd@nbd.name>
* ar71xx: disable sub-page writes on routerboard nand driversFelix Fietkau2017-01-113-0/+3

* ar71xx: fix RB4xx CPLD SPI device mode setupFelix Fietkau2017-01-111-1/+1
| | | | | | | | Commit af79fdbe4af3 changed the code to use tx_nbits for dual SPI tx transfers, however the SPI stack only allows this when the device mode includes the relevant bit as well Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ar71xx: remove AP83 reference design board supportFelix Fietkau2016-12-121-283/+0
| | | | | | | | This board is very old and unlikely to still be relevant today. Support for it contains a significant amount of device specific baggage which is worth getting rid of. Signed-off-by: Felix Fietkau <nbd@nbd.name>

* ar71xx: spi-rb4xx fix.Sergey Sergeev2016-07-021-1/+1
| | | | | | | | In new kernels we should use clk_prepare_enable instead of clk_enable since clk_enable does not make proper initialization that leads to rise WARN_ON messages and not working spi bus on the device. Signed-off-by: Sergey Sergeev <adron@yapic.net>
