48f6693790 ARM: OMAP2+: Remove unused legacy code for McBSP
We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

6b72de4d33 ARM: OMAP2+: Use kcalloc() in sr_set_nvalues()
* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kcalloc".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

98d87eb566 ARM: sunxi: h3-h5: Convert R_CCU raw numbers to macros
Now that the R_CCU device tree binding headers have been merged, we
can convert the raw number references in the device trees to use the
defined macros.

65878b126c ARM: dts: da850-evm: fix tca6416 for use with GPIO hogs
In order GPIOS from this controller to be used with the "gpio-hogs"
property, the tca6416 node has to properly labeled as a gpio-controller,
and use #gpio-cells.

With that, the SEL_A, SEL_B, SEL_C lines that are used to select VPIF
input can be configured using GPIO hogs.

As an example, example, the configuration below selects the analog video
input on the da850-evm UI board:

&tca6416 {
	 status = "okay";

	 sel_a {
		gpio-hog;
		gpios = <7 GPIO_ACTIVE_HIGH>;
		output-high;
		line-name = "ADC_ENn";
	 };
	 sel_b {
		gpio-hog;
		gpios = <6 GPIO_ACTIVE_HIGH>;
		output-high;
		line-name = "CAMERA_ENn";
	 };
	 sel_c {
		gpio-hog;
		gpios = <5 GPIO_ACTIVE_HIGH>;
		output-low;
		line-name = "VIDEO_IN_ENn";
	 };
};
