+config MALI400
+	tristate "Mali-300/400/450 support"
+	depends on ARM || ARM64
+	select DMA_SHARED_BUFFER
+	---help---
+	  This enables support for the ARM Mali-300, Mali-400, and Mali-450
+	  GPUs.
+
+	  To compile this driver as a module, choose M here: the module will be
+	  called mali.
+
+config MALI450
+	bool "Enable Mali-450 support"
+	depends on MALI400
+	---help---
+	  This enables support for Mali-450 specific features.
+
+config MALI470
+	bool "Enable Mali-470 support"
+	depends on MALI400
+	---help---
+	  This enables support for Mali-470 specific features.
+
+config MALI400_DEBUG
+	bool "Enable debug in Mali driver"
+	depends on MALI400
+	---help---
+	  This enabled extra debug checks and messages in the Mali driver.
+
+config MALI400_PROFILING
+	bool "Enable Mali profiling"
+	depends on MALI400
+	select TRACEPOINTS
+	default y
+	---help---
+	  This enables gator profiling of Mali GPU events.
+
+config MALI400_INTERNAL_PROFILING
+	bool "Enable internal Mali profiling API"
+	depends on MALI400_PROFILING
+	default n
+	---help---
+	  This enables the internal legacy Mali profiling API.
+
+config MALI400_UMP
+	bool "Enable UMP support"
+	depends on MALI400
+	---help---
+	  This enables support for the UMP memory sharing API in the Mali driver.
+
+config MALI_DVFS
+	bool "Enable Mali dynamically frequency change"
+	depends on MALI400
+	default y
+	---help---
+	  This enables support for dynamic change frequency of Mali with the goal of lowering power consumption.
+
+config MALI_DMA_BUF_MAP_ON_ATTACH
+	bool "Map dma-buf attachments on attach"
+	depends on MALI400 && DMA_SHARED_BUFFER
+	default y
+	---help---
+	  This makes the Mali driver map dma-buf attachments after doing
+	  attach. If this is not set the dma-buf attachments will be mapped for
+	  every time the GPU need to access the buffer.
+
+	  Mapping for each access can cause lower performance.
+
+config MALI_SHARED_INTERRUPTS
+	bool "Support for shared interrupts"
+	depends on MALI400
+	default n
+	---help---
+	  Adds functionality required to properly support shared interrupts.  Without this support,
+	  the device driver will fail during insmod if it detects shared interrupts.  This also
+	  works when the GPU is not using shared interrupts, but might have a slight performance
+	  impact.
+
+config MALI_PMU_PARALLEL_POWER_UP
+	bool "Power up Mali PMU domains in parallel"
+	depends on MALI400
+	default n
+	---help---
+	  This makes the Mali driver power up all PMU power domains in parallel, instead of
+	  powering up domains one by one, with a slight delay in between. Powering on all power
+	  domains at the same time may cause peak currents higher than what some systems can handle.
+	  These systems must not enable this option.
+
+config MALI_DT
+	bool "Using device tree to initialize module"
+	depends on MALI400 && OF
+	default n
+	---help---
+	  This enable the Mali driver to choose the device tree path to get platform resoures
+	  and disable the old config method. Mali driver could run on the platform which the
+	  device tree is enabled in kernel and corresponding hardware description is implemented
+	  properly in device DTS file.
+
+config MALI_PLAT_SPECIFIC_DT
+	bool "Platform specific Device Tree is being used"
+	depends on MALI_DT
+	default n
+	---help---
+          This is a pragmatic approach for some platforms which make
+          use of a device tree entry that does not strictly comply to
+          what the standard Utgard driver expects to find, but have
+          their platform data implemented the old way.  Such platforms
+          should be converted to using the Device Tree so this
+          configuration option can be removed.
+
+config MALI_QUIET
+	bool "Make Mali driver very quiet"
+	depends on MALI400 && !MALI400_DEBUG
+	default n
+	---help---
+	  This forces the Mali driver to never print any messages.
+
+	  If unsure, say N.
