The Allwinner SoCs all have an ADC that can also act as a touchscreen controller and a thermal sensor. This patch adds the ADC driver which is based on the MFD for the same SoCs ADC. This also registers the thermal adc channel in the iio map array so iio_hwmon could use it without modifying the Device Tree. This registers the driver in the thermal framework. The thermal sensor requires the IP to be in touchscreen mode to return correct values. Therefore, if the user is continuously reading the ADC channel(s), the thermal framework in which the thermal sensor is registered will switch the IP in touchscreen mode to get a temperature value and requires a delay of 100ms (because of the mode switching), then the ADC will switch back to ADC mode and requires also a delay of 100ms. If the ADC readings are critical to user and the SoC temperature is not, this driver is capable of not registering the thermal sensor in the thermal framework and thus, "quicken" the ADC readings. This driver probes on three different platform_device_id to take into account slight differences (registers bit and temperature computation) between Allwinner SoCs ADCs. Signed-off-by:

Due to RST rework, the reference to i2c/trivial-devices was changed, but the result is broken. However, let's just drop the whole reference, since it doesn't make sense in the first place to reference this "global" file for a single driver.

The camera code has an explicit cache flush operation which is not portable. Now that vc04_services is using portable DMA APIs that already do the cache flushing, explicit flushes should no longer be needed. The one call to __cpuc_flush_dcache_area has been removed. Testing: The offical V2 camera for the RPI was tested on a RPI 3 running in 32 bit mode(armhf). The cheese application and ffmpeg was used to view and stream video from the camera. Nothing new seems to be broken without the cache flushing. Signed-off-by:

The structures and the macros in the header file are not used anywhere inside the kernel (verified by using grep). The structures and macros were leftover from the patch 341f1f0a "staging: lustre: remove remote client support". Also, removed the include statements for lustre_eacl.h. Signed-off-by:

The structure is used as an argument to module_param macro. This macro calls a bunch of other macros and finally assigns the instance of the kernel_param_ops structure to the const struct kernel_param_ops* field of a variable of type kernel_param. Hence, const can be added to the structure.

Using LINUXINCLUDE is a very old hack, and doesn't play well with building objects in a different directory than the kernel source is in. So fix up the include file references to be relative to make it obvious we are pulling in local include files, which need to get fixed up. Reported-by:

udelay is impelmented using a busy-wait loop and consumes CPU cycles while usleep_range is implemented using interrupts.cls_flush_uart_write() is called after a channel lock is acquired i.e. an atomic context. Hence delay in this method should use udelay instead of usleep_range. Signed-off-by:
