* mfd: Explicitly include correct DT includesRob Herring2023-08-181-2/+2
| | | | | | | | | | | | | | | 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: sun4i-gpadc: Use devm_platform_get_and_ioremap_resource()Ye Xingchen2023-04-261-3/+1
| | | | | | | | | | Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

* mfd: sun4i-gpadc: Replace irqchip mask_invert with unmask_baseAidan MacDonald2022-12-071-2/+1
| | | | | | | | | | | Remove use of the deprecated mask_invert flag. Inverted mask registers (where a '1' bit enables an IRQ) can be described more directly as an unmask register.

* mfd: sun4i: Drop of_match_ptr from of_device_id tableKrzysztof Kozlowski2020-11-271-1/+1
| | | | | | | | | | | | The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here). This fixes compile warning (!CONFIG_OF on x86_64): drivers/mfd/sun4i-gpadc.c:79:34: warning: ‘sun4i_gpadc_of_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: sun4i-gpadc: Constify static struct resourceRikard Falkeborn2020-11-191-1/+1
| | | | | | | | | Constify adc_resources[]. The only usage is to assign its address to the resources field of the mfd_cell struct. This allows the compiler to put it in read-only memory. Done with the help of Coccinelle. Signed-off-by: Rikard Falkeborn <rikard.falkeborn@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* mfd: Add support for Allwinner SoCs ADCQuentin Schulz2016-11-291-0/+181
The Allwinner SoCs all have an ADC that can also act as a touchscreen controller and a thermal sensor. For now, only the ADC and the thermal sensor drivers are probed by the MFD, the touchscreen controller support will be added later.
