f8f34e91da Check that the pin function exists before setting it.

30068a1de9 Add support for interrupts, sensors and GPIO for AXP209 PMIC.
Pressing the PEK (power enable key) will shutdown the board.
Some events are reported to devd via system "PMU" and subsystem
"Battery", "AC" and "USB" such as connected/disconnected.
Some sensors values (power source voltage/current) are reported via
sysctl (dev.axp209_pmu.X.)
It also expose a gpioc node usable in kernel and userland. Only 3 of
the 4 GPIO are exposed (The GPIO3 is different and mostly unused on
boards). Most popular boards uses GPIO1 as a sense pin for OTG power.
Add a dtsi file that adds gpio-controller capability to the device as
upstream doesn't defined it and include it in our custom DTS.

627c360fa7 Enable USB PHY regulators when requested by the host controller driver.
Previously the USB PHY driver would enable all regulators at attach time.
This prevented boards from booting when powered by the USB OTG port, as
it didn't take VBUS presence into consideration.

9d6672e13b Fix the deciKelvin to Celsius conversion in kernel.
After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.

This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.

343044c43b Add Allwinner A83T thermal sensor controller support.
The A83T thermal sensor controller has three sensors. Sensor 0 corresponds
to CPU cluster 0, sensor 1 to CPU cluster 1, and sensor 2 to the GPU. This
driver exports the temperature sensor readings via sysctl.

Calibration data is obtained from SRAM found in the Secure ID module.

4b9a54a9fc Add a driver for the Allwinner Reduced Serial Bus (RSB).
The RSB controller speaks a simplified two wire protocol at speeds up to

RSB isn't really I2C or SMBus, but the driver exposes an iicbus interface

RSB and I2C connectivity).

cd642c88a1 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

dec4873723 Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc.  This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).

(Thanks to jilles@ for providing the vital clue about the kernel linker.)
