[PATCH V2 0/2] Add i.MX93 Wireless EVK board support

[PATCH V2 0/2] Add i.MX93 Wireless EVK board support

[Sherry Sun]

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.

Add device tree and dt-binding for i.MX93 Wireless EVK.

---
Changes in V2:
1. Rename the compatible string to fsl,imx93-wireless-evk which is more
   clearer and better aligned with the naming convention used on previous
   NXP boards.
2. Impreove the patch#1 commit message to add more info.

[PATCH V2 1/2] dt-bindings: arm: fsl: Add i.MX93 Wireless EVK board

[Sherry Sun]

Add DT compatible string for NXP i.MX93 Wireless EVK board.

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.

The detailed differences between i.MX93 Wireless EVK and i.MX93 11x11
EVK board can be found in i.MX93 Wireless EVK DTS patch commit message.

[PATCH V2 2/2] arch: arm64: imx93-wevk: Add i.MX93 Wireless EVK board support

[Sherry Sun]

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)

I will leave it to the platform maintainer whether SiP deserves its own
compatible. I imagine that yes, but don't insist so:

Drop. Do not reference other patches in terms what do they provide - it
serves little purpose in git history.

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.

Hi Krzysztof,
Ok, it seems I should mark these nodes as disabled instead of delete them, will fix, thanks!

Will fix in V3.

Perhaps I should simply use the DTS overlay for i.MX93 Wireless EVK, or
extract their common parts, such as imx93-11x11-evk-common.dtsi, not sure
which is better?

Will avoid such changes.

Ok, will fix. Thanks!

Still wrong. How component present in the board can be missing in the
same time? You included other DTS for a reason which means this board
grows on the previous design.
