mfd: bcm2835-pm: Add support for BCM2711

2022-07-04T10:42:20Z

In BCM2711 the new RPiVid ASB took over V3D. The old ASB is still present with the ISP and H264 bits, and V3D is in the same place in the new ASB as the old one. As per the devicetree bindings, BCM2711 will provide both the old and new ASB resources, so get both of them and pass them into 'bcm2835-power,' which will take care of selecting which one to use accordingly. Since the RPiVid ASB's resources were being provided prior to formalizing the bindings[1], also support the old DT files that didn't use 'reg-names.'

soc: bcm: bcm2835-pm: Add support for power domains under a new binding.

2019-01-09T15:55:09Z

This provides a free software alternative to raspberrypi-power.c's firmware calls to manage power domains. It also exposes a reset line, where previously the vc4 driver had to try to force power off the domain in order to trigger a reset.

bcm2835-pm: Move bcm2835-watchdog's DT probe to an MFD.

2019-01-09T15:55:06Z

The PM block that the wdt driver was binding to actually has multiple features we want to expose (power domains, reset, watchdog). Move the DT attachment to a MFD driver and make WDT probe against MFD. Signed-off-by: Eric Anholt Reviewed-by: Guenter Roeck Acked-by: Stefan Wahren Signed-off-by: Stefan Wahren
