Subject: ath79: fix spi-max-frequency for wAP G-5HacT2HnD
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9de6bc872af50c80f0ba449422f413cfa613f7e5;p=openwrt%2Fstaging%2Fthess.git

ath79: fix spi-max-frequency for wAP G-5HacT2HnD

The introduction of ebf0d8dade (ath79: add new ar934x spi driver)
made the SPI memory unusable. Reducing the spi-max-frequency to
a smaller value makes it work again.

Tested on two MikroTik RouterBOARD wAP G-5HacT2HnD devices.
