mfd: Use dev_fwnode() instead of of_fwnode_handle()

2025-07-24T10:27:02+00:00

irq_domain_create_simple() takes fwnode as the first argument. It can be extracted from the struct device using dev_fwnode() helper instead of using of_node with of_fwnode_handle(). So use the dev_fwnode() helper. Signed-off-by: "Jiri Slaby (SUSE)" Reviewed-by: Charles Keepax Link: https://lore.kernel.org/r/20250611104348.192092-13-jirislaby@kernel.org Signed-off-by: Lee Jones

mfd: Switch to irq_domain_create_*()

2025-05-16T19:06:10+00:00

irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

mfd: Explicitly include correct DT includes

2023-08-18T20:48:03+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.

mfd: Switch i2c drivers back to use .probe()

2023-06-15T08:19:37+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c 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.

mfd: tps65xxx: Constify static struct resource in OMAP2+ drivers

2020-11-19T08:34:21+00:00

Constify a number of static struct resource. The only usage of the structs are to assign their address to the resources field in the mfd_cell struct. This allows the compiler to put them in read-only memory. Done with the help of Coccinelle. Signed-off-by: Rikard Falkeborn Signed-off-by: Lee Jones

mfd: Replace HTTP links with HTTPS ones

2020-08-13T06:50:59+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

mfd: tps65217: Introduce dependency on CONFIG_OF

2017-10-13T09:42:58+00:00

Currently the driver boots only via device tree hence add a dependency on CONFIG_OF. This leaves with a bunch of unused code so clean that up. This patch also makes use of probe_new function in place of the probe function so as to avoid passing i2c_device_id.
