Subject: ppc/pnv/occ: Update pstate frequency tables
X-Git-Tag: v10.0.0-rc0~10^2~59
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fedbab2c512e8685c2ae87a05f8862e5e83f81ed;p=thirdparty%2Fqemu.git

ppc/pnv/occ: Update pstate frequency tables

OCC pstate frequencies are in kHz, so the OCC data was 3-4MHz. Upgrade
to GHz. Make each pstate have a different frequency.
