Subject: ath79: convert pcs,cap324 calibration to nvmem
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=79fc4dba6014cf653bf43099e6742028b222f6f5;p=openwrt%2Fstaging%2Fnbd.git

ath79: convert pcs,cap324 calibration to nvmem

Userspace handling is deprecated.

Also fix a bug with userspace handling where the wrong calibration data
was being used for the PCI card. The dts was correct but userspace was
not.
