firmware: xilinx: Move FIRMWARE_VERSION_MASK to xlnx-zynqmp.h

2024-06-03T11:07:56+00:00

Move FIRMWARE_VERSION_MASK macro to xlnx-zynqmp.h so that other
drivers can use it for verifying the supported firmware version.

firmware: zynqmp: Convert to platform remove callback returning void

2024-01-04T16:01:15+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

firmware: xilinx: Remove clock_setrate and clock_getrate api

2023-12-15T16:27:04+00:00

As per the current code base, PM_CLOCK_SETRATE and PM_CLOCK_GETRATE
APIs are not supported for the runtime operations. In the case of
ZynqMP returning an error from TF-A when there is any request to
access these APIs and for Versal also it is returning an error like
NO_ACCESS from the firmware. So, just removing the unused code to
avoid the confusion around these APIs.

Also, there is no issue with the backward compatibility as these APIs
were never used since implemented. Hence no need to bump up the
version of the feature check API as well.

drivers: soc: xilinx: Fix error message on SGI registration failure

2023-12-07T02:18:29+00:00

Failure to register SGI for firmware event notification is non-fatal error
when feature is not supported by other modules such as Xen and TF-A. Add
_info level log message for such special case.

Also add XST_PM_INVALID_VERSION error code and map it to -EOPNOSUPP Linux
kernel error code. If feature is not supported or EEMI API version is
mismatch, firmware can return XST_PM_INVALID_VERSION = 4 or
XST_PM_NO_FEATURE = 19 error code.

firmware: xilinx: Expand feature check to support all PLM modules

2023-12-07T02:18:28+00:00

To support feature check for all modules, append the module id of the API
that is being checked to the feature check API so it could be routed to
the target module for processing.

There is no need to check compatible string because the board information
is taken via firmware interface.
