Xingyu Chen bdb369e1e9 reset: add support for the Meson-A1 SoC Reset Controller
The number of RESET registers and offset of RESET_LEVEL register for
Meson-A1 are different from previous SoCs, In order to describe these
differences, we introduce the struct meson_reset_param.

Martin Blumenstingl 320da785db reset: meson: enable level reset support on Meson8b
Commit a5a10afe04 ("reset: meson: add level reset support for GX SoC
family") only enabled the level resets for the newer GX SoC family.
However, the older 32-Meson SoCs (Meson8, Meson8b and Meson8m2) also
support level resets using the same offset as the newer GX SoCs.

This removes the separation between Meson8b and the GX SoCs from the
reset-meson driver to enable the level resets also on Meson8b.

Neil Armstrong 7e8838fe59 reset: meson: remove unneeded check in meson_reset_reset
The if (bank >= REG_COUNT) is not need since already checked
by the default rcdev->of_xlate implementation which guarantees that
id < rcdev->nr_resets.

Neil Armstrong a5a10afe04 reset: meson: add level reset support for GX SoC family
The Amlogic GX SoC family embeds alternate registers to drive the reset
levels next to the pulse registers.

This patch adds support for level reset handling on the GX family only.

The Meson8 family has an alternate way to handle level reset.

Paul Gortmaker 8290924e68 reset: meson: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

arch/arm/mach-meson/Kconfig:menuconfig ARCH_MESON
arch/arm/mach-meson/Kconfig:    bool "Amlogic Meson SoCs"

arch/arm64/Kconfig.platforms:config ARCH_MESON
arch/arm64/Kconfig.platforms:   bool "Amlogic Platforms"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
