Subject: [PATCH v8 0/3] riscv: sophgo: add dmamux support for Sophgo CV1800/SG2000 SoCs
Date: Fri, 12 Apr 2024 15:06:26 +0800 [thread overview]
Message-ID: <IA1PR20MB495359880A3A8C4947702BB5BB042@IA1PR20MB4953.namprd20.prod.outlook.com> (raw)
Add dma multiplexer support for the Sophgo CV1800/SG2000 SoCs.
As the syscon device of CV1800 have a usb phy subdevices. The
binding of the syscon can not be complete without the usb phy
is finished. As a result, the binding of syscon is removed
and will be evolved in its original series after the usb phy
binding is fully explored.
Changed from v7:
1. remove unused variable
Changed from v6:
1. fix copyright time.
2. driver only output mapping info in when debugging.
3. remove dma-master check in the driver init since the binding
always require it.
Changed from v5:
1. remove dead binding header.
2. make "reg" required so the syscon binding can have the same
example node of the dmamux binding.
Changed from v4:
1. remove the syscon binding since it can not be complete (still
lack some subdevices)
2. add reg description for the binding,
3. remove the fixed channel assign for dmamux binding
3. driver adopt to the binding change. Now the driver allocates all the
channel when initing and maps the request chan to the channel dynamicly.
Changed from v3:
1. fix dt-binding address issue.
Changed from v2:
1. add reg property of dmamux node in the binding of patch 2
Changed from v1:
1. fix wrong title of patch 2.
