From 3adc11e5fc5fc0925aa298c8ef327224459f80bf Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Wed, 27 Apr 2022 08:51:25 +0200 Subject: [PATCH] net: lan966x: Add registers used to configure the PTP pin Add registers that are used to configure the PTP pins. These registers are used to enable the interrupts per PTP pin and to set the waveform generated by the pin. Signed-off-by: Horatiu Vultur Signed-off-by: David S.
