	  Enable support for mcux DCNano LCDIF driver.

config MCUX_DCNANO_LCDIF_DOUBLE_FRAMEBUFFER
	bool "Double framebuffer"
	help
	  Enable dual framebuffer for LCDIF peripheral. Two framebuffers
	  will be allocated, and switched between for each frame.
	  Note that for partial display updates, the prior framebuffer must
	  be copied into the next one. This can have significant performance
	  impact.

config MCUX_DCNANO_LCDIF_MAINTAIN_CACHE
	bool "Maintain cache coherency"
	default y
	help
	  Maintain cache coherency for LCDIF framebuffer. This is generally
	  required, unless an external framebuffer is utilized with custom
	  caching settings, or caching is disabled.

config MCUX_DCNANO_LCDIF_EXTERNAL_FB_MEM
	bool "Use external memory for framebuffer"
	imply MEMC
	help
	  Use external memory for framebuffer. Configures the LCDIF to write
	  framebuffer data to a memory mapped external device.

	  Note that no specific linker section is used for this framebuffer, so
	  if the application uses the external memory for other purposes, care
	  should be taken to ensure that the memory allocated for the LCDIF
	  does not overlap with other data. Each allocated LCDIF buffer will
	  utilize (lcd_width * lcd_height * bytes_per_pixel) bytes of data,
	  and buffers will be allocated contiguously.

	help
	  Address of memory mapped external framebuffer.
	  Must be 128 byte aligned
