net: dsa: Move KS8995 to the DSA subsystem

2025-08-19T00:26:09+00:00

By reading the datasheets for the KS8995 it is obvious that this is a 100 Mbit DSA switch. Let us start the refactoring by moving it to the DSA subsystem to preserve development history. Verified that the chip still probes the same after this patch provided CONFIG_HAVE_NET_DSA, CONFIG_NET_DSA and CONFIG_DSA_KS8995 are selected.

sysfs: treewide: switch back to bin_attribute::read()/write()

2025-06-17T08:44:13+00:00

The bin_attribute argument of bin_attribute::read() is now const. This makes the _new() callbacks unnecessary. Switch all users back.

net: phy: ks8995: constify 'struct bin_attribute'

2024-12-18T03:00:44+00:00

The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications.

net: phy: ks8995: drop of_match_ptr for ID table

2023-03-15T08:11:02+00:00

The driver will match mostly by DT table (even thought there is regular ID table) so there is little benefit in of_match_ptr (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/net/phy/spi_ks8995.c:156:34: error: ‘ks8895_spi_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S.

net: phy: spi_ks8895: switch to using gpiod API

2022-09-15T09:43:51+00:00

This patch switches the driver away from legacy gpio/of_gpio API to gpiod API, and removes use of of_get_named_gpio_flags() which I want to make private to gpiolib.

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
