Use platform_get_resource() to fetch the memory resource instead of acpi_walk_resources() and devm_ioremap_resource() for mapping the resources. PS: We cannot use resource_size() here because it adds an extra byte to round off the size. In the case of PMF ResourceTemplate(), this rounding is already handled within the _CRS. Using resource_size() would increase the resource size by 1, causing a mismatch with the length field and leading to issues. Therefore, simply use end-start of the ACPI resource to obtain the actual length.

This driver provides support for the AMD Platform Management Framework.
|
|
The goal is to enhance end user experience by making AMD PCs smarter,
|
|
quiter, power efficient by adapting to user behavior and environment.
|
|
|
|
To compile this driver as a module, choose M here: the module will
|
|
be called amd_pmf.
|
|
|
|
config AMD_PMF_DEBUG

|
|
Enabling this option would give more debug information on the OEM fed
|
|
power setting values for each of the PMF feature. PMF driver gets this
|
|
information after evaluating a ACPI method and the information is stored
|
|
in the PMF config store.

|
Say Y here to enable more debug logs and Say N here if you are not sure.
