Subject: ath79: increase spi clock for D-Link DIR-842
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=64d088d8f9f2fbca75f3240ced5cf40b721dc3f2;p=openwrt%2Fstaging%2Frobimarko.git

ath79: increase spi clock for D-Link DIR-842

AHB is 258 MHz for this device (CPU_PLL / 3), but there is no difference
between 64 MHz and 50 MHz for spi-max-frequency, thus increase to 50 MHz.

Tested on revisions C1 and C3.
