2018-02-16reset: meson: enable level reset support on Meson8bMartin Blumenstingl
Commit a5a10afe04ef ("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.

2017-10-17reset: meson: remove unneeded check in meson_reset_resetNeil Armstrong
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.

2017-10-17reset: meson: add level reset support for GX SoC familyNeil Armstrong
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. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-03-08reset: meson: make it explicitly non-modularPaul Gortmaker
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.
