From: Jacob Keller Date: Wed, 9 Nov 2022 23:09:44 +0000 (-0800) Subject: ptp: convert remaining drivers to adjfine interface X-Git-Tag: v6.6.7~3913^2~232^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2bd9c76c89fbe25df351fc5902cbbcca6a7d372;p=platform%2Fkernel%2Flinux-starfive.git ptp: convert remaining drivers to adjfine interface Convert all remaining drivers that still use .adjfreq to the newer .adjfine implementation. These drivers are not straightforward, as they use non-standard methods of programming their hardware. They are all converted to use scaled_ppm_to_ppb to get the parts per billion value that their logic depends on.
