pmdomain: xilinx: Move Kconfig option to the pmdomain subsystem

2023-10-04T21:41:56+00:00

The Kconfig option belongs closer to the corresponding implementation,
hence let's move it from the soc subsystem to the pmdomain subsystem.

soc: xilinx: Do not check for 0 return after calling platform_get_irq()

2023-08-04T06:53:21+00:00

There is no possible for platform_get_irq() to
return 0. Use the return value from platform_get_irq().

soc: xilinx: Explicitly include correct DT includes

2023-08-04T06:50:05+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

soc: xilinx: Move power-domain driver to the genpd dir

2023-07-14T08:41:59+00:00

To simplify with maintenance let's move the xilinx power-domain driver to
the new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.

driver: soc: xilinx: Convert to platform remove callback returning void

2023-07-10T11:01:09+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 only effect compared to returning
zero is that the core emits an error message. By converting to
.remove_new() (which is semantically equivalent to return 0 in
.remove()) this error message is suppressed which is a good thing as
xlnx_event_manager_remove() already emits an better error message.

driver: soc: xilinx: use _safe loop iterator to avoid a use after free

2023-05-12T11:08:04+00:00

The hash_for_each_possible() loop dereferences "eve_data" to get the
next item on the list.  However the loop frees eve_data so it leads to
a use after free.  Use hash_for_each_possible_safe() instead.

soc: xilinx: Use of_property_present() for testing DT property presence

2023-05-12T11:06:14+00:00

It is preferred to use typed property access functions (i.e.
of_property_read_ functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

driver: soc: xilinx: fix memory leak in xlnx_add_cb_for_notify_event()

2023-01-05T08:46:51+00:00

The kfree() should be called when memory fails to be allocated for
cb_data in xlnx_add_cb_for_notify_event(), otherwise there will be
a memory leak, so add kfree() to fix it.
