Communicating with the Raspberry Pi firmware is currently handled by each driver calling into the mbox driver, however the device tree is structured such that they should be calling into a firmware driver. Add a driver for this node with an interface to communicate to the firmware via the mbox interface. There is a sysctl to get the firmware revision. This is a unix date so can be parsed with: root@generic:~ # date -j -f '%s' sysctl -n dev.bcm2835_firmware.0.revision Tue Nov 19 16:40:28 UTC 2019 Reviewed by: manu Sponsored by: Innovate UK Differential Revision: https://reviews.freebsd.org/D25572 |
