* ath79: reduce spi-max-frequency to 50 MHzAdrian Schmutzler2020-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The introduction of ebf0d8dadeca ("ath79: add new ar934x spi driver") made the SPI memory unusable on devices with very high spi-max-frequency (104 MHz). Here's how the actual clock is calculated: (AHB_CLK/((CLOCK_DIVIDER+1)*2)) where AHB_CLK is a fixed clock (e.g. 200MHz on AR9331) and CLOCK_DIVIDER is the parameter we can set. Highest clock according to this formula is AHB_CLK/2 (100MHz, but that didn't work in device tests). The next possible value is AHB_CLK/4 (50MHz). Speeds between 50 MHz and 100 MHz will be rounded down, so using values higher than 50 MHz does not provide any benefit. Consequently, this patch reduces spi-max-frequency for all devices with values higher than 50 MHz to 50 MHz (effectively, this only affects devices with 104 MHz before this patch). Tested on GL.inet GL-AR150: Boot fails with 104 MHz but is successful with both 50 MHz and 80 MHz (fast-read), where the latter two yield identical read speeds.

* ath79: remove redundant mtd-mac-address for wmacAdrian Schmutzler2019-10-271-1/+0
| | | | | | | | | | | | | | For several devices, wmac MAC address is set from art 0x1002 explicitly by using mtd-mac-address although mtd-cal-data is pulled from art 0x1000. With the MAC address in 0x1002, the driver should automatically use it when reading caldata from 0x1000. Thus, remove the redundant mtd-mac-address for those devices.

* ath79: provide label MAC addressAdrian Schmutzler2019-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the label MAC address for several devices in ath79. Some devices require setting the MAC address in 02_network: For the following devices, the netif device can be linked in device tree, but the MAC address cannot be read: - alfa-network,ap121f - avm,fritz300e - ubnt-xm devices For the following devices, label MAC address is tied to lan or wan, so no node to link to exists in device tree: - adtran,bsap1800-v2 - adtran,bsap1840 - dlink,dir-842-c1/-c2/-c3 - engenius,ecb1750 - iodata,etg3-r - iodata,wn-ac1167dgr - iodata,wn-ac1600dgr - iodata,wn-ac1600dgr2 - iodata,wn-ag300dgr - nec,wg800hp - nec,wg1200cr - trendnet,tew-823dru Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
