72bb8275a3 reset: amlogic: aux: drop aux registration helper 
Having the aux registration helper along with the registered driver is not
great dependency wise. It does not allow the registering driver to be
properly decoupled from the registered auxiliary driver.

Drop the registration helper from the amlogic auxiliary reset driver.
This will be handled in the registering clock driver to start with while
a more generic solution is worked on.

ccfba09cee reset: amlogic: aux: get regmap through parent device 
Get regmap directly from the parent device registering the
auxiliary reset driver, instead of using device data attached
to the auxiliary device.

This simplifies the registration a bit.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {

fb4c31587a reset: amlogic: add auxiliary reset driver support 
Add support for the reset controller present in the audio clock
controller of the g12 and sm1 SoC families, using the auxiliary bus.

This is expected to replace the driver currently present directly
within the related clock driver.
