From 14193ea2bfee7bcd1c0e3aa1cbc4e09e15887847 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 16 Oct 2020 18:02:15 +0200 Subject: can: mcp251xfd: mcp251xfd_chip_timestamp_init(): factor out into separate function This patch factors out the timestamp initialization from the clock initialization. This is a preparation patch for the PLL support, where clock and timestamp init must be done separately.
