mfd: Use i2c_get_match_data() in a selection of drivers

2023-11-01T10:02:17+00:00

Use preferred i2c_get_match_data() instead of of_match_device() and i2c driver_data to get the driver match data. With this, adjust the includes to explicitly include the correct headers.

mfd: wm31x: Fix Wvoid-pointer-to-enum-cast warning

2023-08-22T07:07:52+00:00

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1 causes: wm831x-spi.c:36:10: error: cast to smaller integer type 'enum wm831x_parent' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20230810095849.123321-8-krzysztof.kozlowski@linaro.org Signed-off-by: Lee Jones

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.

mfd: wm831x-i2c: Convert to i2c's .probe_new()

2022-12-07T13:27:26+00:00

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Acked-by: Charles Keepax Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-479-uwe@kleine-koenig.org

mfd: wm831x-i2c: Make it explicitly non-modular

2019-02-01T08:21:13+00:00

The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_WM831X_I2C drivers/mfd/Kconfig: bool "Wolfson Microelectronics WM831x/2x PMICs with I2C" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

mfd: wm831x: Add basic device tree binding

2017-03-23T11:45:50+00:00

Add the basic ability to register the device through device tree, more work is needed to get each individual sub-driver functioning correctly but this is enough to get the device to probe from device tree. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones
