From: Bastien Curutchet (Schneider Electric) Date: Mon, 5 Jan 2026 13:08:04 +0000 (+0100) Subject: net: dsa: microchip: Use regs[] to access REG_PTP_RTC_SEC X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=776ad30de04e26b705ce2c36d7efe99aa6f12d6f;p=thirdparty%2Fkernel%2Flinux.git net: dsa: microchip: Use regs[] to access REG_PTP_RTC_SEC Accesses to the PTP_RTC_SEC register are done through a hardcoded address which doesn't match with the KSZ8463's register layout. Add a new entry for the PTP_RTC_SEC register in the regs[] tables. Use the regs[] table to retrieve the PTP_RTC_SEC register address when accessing it. Remove the macro defining the address to prevent further use.
