Subject: [PATCH] ARM: bcm283x: Extend the WDT DT node out to cover the
|
2019-07-09 18:32:28 +00:00
|
|
|
whole PM block. (v4)
|
|
|
|
|
|
|
|
|
|
It was covering part of the PM block's range, up to the WDT regs. To
|
|
|
|
|
support the rest of the PM block's functionality, we need the full
|
|
|
|
|
register range plus the AXI Async Bridge regs for PM sequencing.
|
|
|
|
|
|
|
|
|
|
This doesn't convert any of the consumers over to the new binding yet,
|
|
|
|
|
since we will need to be careful in coordinating our usage of firmware
|
|
|
|
|
services that might power domains on and off versus the bcm2835-pm
|
|
|
|
|
driver's access of those same domains.
