2020-11-27mfd: sun4i: Drop of_match_ptr from of_device_id tableKrzysztof Kozlowski1-1/+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>
2020-11-19mfd: sun4i-gpadc: Constify static struct resourceRikard Falkeborn1-1/+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>

2016-11-29mfd: sun4i-gpadc: Fix 'cast from pointer to integer of different size' warningLee Jones1-1/+1
When building for X86 using COMPILE_TEST we get this warning: ../drivers/mfd/sun4i-gpadc.c: In function ‘sun4i_gpadc_probe’: ../drivers/mfd/sun4i-gpadc.c:110:10: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] Since an integer and a pointer are difference sizes on 64bit architectures. Convert to case to a long instead. Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-11-29mfd: Add support for Allwinner SoCs ADCQuentin Schulz1-0/+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.
