[PATCH V2 2/2] arch: arm64: imx93-wevk: Add i.MX93 Wireless EVK board support
Posted by Sherry Sun 2 weeks, 3 days ago 
i.MX93 Wireless SiP is created by integrating i.MX93 and IW610 WLCSP
(Wi-Fi + BLE + 802.15.4). And i.MX93 Wireless EVK board with the i.MX93
Wireless SiP basically reuse the i.MX93 11x11 EVK board, with some minor
functional and pin connection differences.

Here are the detailed differences between i.MX93 Wireless EVK and i.MX93
11x11 EVK board.

Function differences:
Function	i.MX93W EVK			i.MX93 EVK
WIFI/BT		IW610 in i.MX93W		IW612 M.2 module
MQS		N				Y
PDM MIC		N				Y
M.2		N				Y
RPi 40-pin HDR	Limited support(pin conflict) 	Y

Pin connection differences:
Function  Signal name	i.MX93W EVK		i.MX93 EVK
WIFI/BT	  SPI_FRM	SAI1_TXFS (spi1.PCS0)	GPIO_IO08 (spi3.PCS0)
	  SPI_TXD	SAI1_TXC (spi1.SIN)	GPIO_IO09 (spi3.SIN)
	  SPI_RXD	SAI1_RXD0 (spi1.SOUT)	GPIO_IO10 (spi3.SOUT)
	  SPI_CLK	SAI1_TXD0 (spi1.SCK)	GPIO_IO11 (spi3.SCK)
	  SPI_INT	CCM_CLKO1		on-board IO expander
	  NB_WAKE_IN	PDM_CLK			on-module IO expander
	  WL_WAKE_IN	PDM_BIT_STREAM0		on-module IO expander
	  IND_RST_WL	PDM_BIT_STREAM1		on-module IO expander
	  IND_RST_NB	GPIO_IO28		on-module IO expander
	  PDn		GPIO_IO29		on-module IO expander
	  NB_WAKE_OUT	GPIO_IO14		on-board IO expander
	  WL_WAKE_OUT	GPIO_IO15		CCM_CLKO1
I2C3	  I2C3_SDA	GPIO_IO00		GPIO_IO28
	  I2C3_SCL	GPIO_IO01		GPIO_IO29

If you remove nodes then clearly you do not share a common design, thus
you should not include other DTSI... and definitely even more confusing
to include other DTS.

Kind of same here.

It's poor practice to include DTS inside DTS, some platforms disallow
this. Is it acceptable pattern in NXP/iMX?

Why do you remove so much?

Do you understand how inclusion works? You claim here you have common
parts. Removing them means they are not common.

Some old platform used it. It is discouraged for new platform.
