Subject: [PATCH 13/17] dt-bindings: can: flexcan: remove ack_grp and ack_bit from fsl,stop-mode
Date: Wed, 7 Oct 2020 23:31:55 +0200 [thread overview]
Message-ID: <20201007213159.1959308-14-mkl@pengutronix.de> (raw)
In-Reply-To: <20201007213159.1959308-1-mkl@pengutronix.de>
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.

gpr is the phandle to general purpose register node.
req_gpr is the gpr register offset of CAN stop request.
