net: ethernet: xilinx: Drop kernel doc comment about return value

2023-10-01T13:00:27+00:00

During review of the patch that became 2e0ec0afa902 ("net: ethernet:
xilinx: Convert to platform remove callback returning void") in
net-next, Radhey Shyam Pandey pointed out that the change makes the
documentation about the return value obsolete. The patch was applied
without addressing this feedback, so here comes a fix in a separate
patch.

net: ethernet: xilinx: Convert to platform remove callback returning void

2023-09-20T08:06:41+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() is renamed to .remove().

Trivially convert these drivers from always returning zero in the remove
callback to the void returning variant.

net: ll_temac: fix error checking of irq_of_parse_and_map()

2023-08-01T21:38:17+00:00

Most kernel functions return negative error codes but some irq functions
return zero on error.  In this code irq_of_parse_and_map(), returns zero
and platform_get_irq() returns negative error codes.  We need to handle
both cases appropriately.

net: Explicitly include correct DT includes

2023-07-28T03:33:16+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.

net: axienet: Move reset before 64-bit DMA detection

2023-06-24T22:39:38+00:00

64-bit DMA detection will fail if axienet was started before (by boot
loader, boot ROM, etc). In this state axienet will not start properly.
XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
is used to fetch the first descriptor. So iowrite32()/ioread32() trick
to this register to detect 64-bit DMA will not work.
So move axienet reset before 64-bit DMA detection.

net: phylink: pass neg_mode into phylink_mii_c22_pcs_config()

Convert fman_dtsec, xilinx_axienet and pcs-lynx to pass the neg_mode
into phylink_mii_c22_pcs_config(). Where appropriate, drivers are
updated to have neg_mode passed into their pcs_config() and
pcs_link_up() functions. For other drivers, we just hoist the call
to phylink_pcs_neg_mode() to their pcs_config() method out of
phylink_mii_c22_pcs_config().

net: Use of_property_read_bool() for boolean properties

2023-03-16T17:41:28+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.
Convert reading boolean properties to of_property_read_bool().
