Subject: [PATCH v10 05/15] dt-bindings: soc: amd: amd,pensando-elbasr: Add AMD Pensando SoC System Controller
Date: Sun, 5 Mar 2023 20:07:29 -0800 [thread overview]
Message-ID: <20230306040739.51488-6-blarson@amd.com> (raw)
In-Reply-To: <20230306040739.51488-1-blarson@amd.com>
Support the AMD Pensando SoC Controller which is a SPI connected device
providing a miscellaneous set of essential board control/status registers.
This device is present in all Pensando SoC based designs.
Signed-off-by: Brad Larson <blarson@amd.com>
---
v10 changes:
- Property renamed to amd,pensando-ctrl
- Driver is renamed and moved to soc/drivers/amd affecting binding
- Delete cs property, driver handles device node creation from parent num-cs
fixing schema reg error in a different way
v9 changes:
- Instead of four nodes, one per chip-select, a single
node is used with reset-cells in the parent.
- No MFD API is used anymore in the driver so it made
sense to move this to drivers/spi.
- This driver is common for all Pensando SoC based designs
so changed the name to pensando-sr.c to not make it Elba
SoC specific.
- Added property cs for the chip-select number which is used
by the driver to create /dev/pensr0.<cs>
