Subject: [RFC PATCH 0/7] reset: make RESET_CONTROLLER a select'ed option

When I was implementing a new reset controller for my SoCs,
I struggled to make my sub-menu shown under the reset
controller menu.
I noticed the Kconfig in reset sub-system are screwed up due to two
config options (ARCH_HAS_RESET_CONTROLLER and RESET_CONTROLLER).

I think only the former should be select'ed by relevant SoCs,
but in fact the latter is also select'ed here and there.
Mixing "select" to a user-configurable option is a mess.

Finally, I started to wonder whether it could be more simpler?

The first patch drops ARCH_HAS_RESET_CONTROLLER.
RESET_CONTROLLER should be directly selected by SoCs.

The rest of this series are minor clean ups in other
sub-systems.
I can postpone them if changes over cross sub-systems
are not preferred.



Masahiro Yamada (7):
  reset: drop ARCH_HAS_RESET_CONTROLLER
  spi: sunxi: remove redundant "depends on RESET_CONTROLLER"
  spi: tegra: remove redundant "depends on RESET_CONTROLLER"
  pinctrl: sunxi: remove redundant "depends on RESET_CONTROLLER"
  drm/sti: replace "select RESET_CONTROLLER" with "depends on ..."
  drm/rockchip: remove redundant "depends on RESET_CONTROLLER"
  drm/tegra: tegra: remove redundant "depends on RESET_CONTROLLER"
