From e4245bbca91da17c7e8c026d2aecf10687519a2b Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Sun, 14 Jun 2020 21:10:38 +0200 Subject: [PATCH] dt-bindings: can: flexcan: remove ack_grp and ack_bit from fsl,stop-mode Since commit: 048e3a34a2e7 can: flexcan: poll MCR_LPM_ACK instead of GPR ACK for stop mode acknowledgment the driver polls the IP core's internal bit MCR[LPM_ACK] as stop mode acknowledge and not the acknowledgment on chip level. This means the 4th and 5th value of the property "fsl,stop-mode" isn't used anymore. It will be removed from the driver in the next patch, so remove it from the binding documentation.
