Subject: [PATCH v7 0/4] Marvell HW overlay support for Cadence xSPI
This patch series adds support for the second version of the Marvell
hardware overlay for the Cadence xSPI IP block. The overlay is a hardware
change made around the original xSPI block. It extends xSPI features with
clock configuration, interrupt masking, and full-duplex, variable-length SPI
operations.
These functionalities allow the xSPI block to operate not only with memory
devices but also with simple SPI devices and TPM devices.
Changes:
v7:
Rebase patches to latest sources, changes in "Allow to read basic xSPI configuration
from ACPI"
Removed bugfix, as it was integrated to next tree from v6
v6:
Fix item order in cdns,xspi.yaml
v5:
Rework cdns,xspi.yaml file
Reword commit messages
Move mamory mapping to ACPI patch
Use devm_platform_ioremap_resource instead of two step mapping
v4:
Rename new Marvell registers to keep naming conventions
Rename mrvl,xspi-nor to marvell,cnxx,xspi-nor
Various fixed for cdns,xspi.yaml file:
- Remove unnecesary parameters
- Link register xferbase with marvell,cn10-xspi-nor
- Move default values to .c file from device-tree
Clock configuration optimization
ACPI fixes:
- Remove incorrect ACPI match table
Added .data field to device_id, fixes for matching in ACPI and dtb case
Minor style comment changes
v3:
Removed all kconfig changes
Added device-tree mrvl,xspi-nor tag
v2:
Support for second overlay iteration
v1:
-
v0:
Initial support for v1 overlay
