	select DRM_MIPI_DSI
	help
	  Dummy config option used to enable hidden DRM configs.
	  These are normally selected implicitely when including a
	  DRM module, but for GKI, the modules are built out-of-tree.

config GKI_HIDDEN_REGMAP_CONFIGS
	bool "Hidden Regmap configs needed for GKI"
	select REGMAP_IRQ
	select REGMAP_MMIO
	help
	  Dummy config option used to enable hidden regmap configs.
	  These are normally selected implicitely when a module
	  that relies on it is configured.

config GKI_HIDDEN_SND_SOC_CONFIGS
	bool "Hidden SND_SOC configs needed for GKI"
	select SND_SOC_GENERIC_DMAENGINE_PCM if (SND_SOC && SND)
	select SND_PCM_IEC958
	help
	  Dummy config option used to enable hidden SND_SOC configs.
	  These are normally selected implicitely when a module
	  that relies on it is configured.

	select PINCTRL_SINGLE if (PINCTRL && OF && HAS_IOMEM)
	select GPIO_PL061 if (HAS_IOMEM && ARM_AMBA && GPIOLIB)
	help
	  Dummy config option used to enable hidden GPIO configs.
	  These are normally selected implicitely when a module
	  that relies on it is configured.

# LEGACY_WEXT_ALLCONFIG Discussed upstream, soundly rejected as a unique
# problem for GKI to solve.  It should be noted that these extensions are
# in-effect deprecated and generally unsupported and we should pressure
# the SOC vendors to drop any modules that require these extensions.

	bool "Hidden wireless extension configs needed for GKI"
	select WIRELESS_EXT
	select WEXT_CORE

	select WEXT_SPY
	select WEXT_PRIV
	help
	  Dummy config option used to enable all the hidden legacy wireless
	  extensions to the core wireless network functionality used by
	  add-in modules.

	  If you are not building a kernel to be used for a variety of
	  out-of-kernel built wireless modules, say N here.

# Atrocities needed for
# a) building GKI modules in separate tree, or
# b) building drivers that are not modularizable
#
# All of these should be reworked into an upstream solution
# if possible.

	  Dummy config option used to enable core functionality used by
	  modules that may not be selectable in this config.

	  Unless you are building a GKI kernel to be used with modules
	  built from a different config, say N here.
