[PATCH v2 0/2] ARM: dts: imx6: phytec-mira: phyBOARD-Mira fixes

[Primoz Fiser]

Two small fixes for the PHYTEC phyBOARD-Mira-i.MX6 boards:

- Since commit 888e5fad9b78 ("Input: stmpe - add axis inversion and
  swapping capability") landed, the touchscreen axis inversion these
  boards need can be described in devicetree instead of userspace (2/2).
- Fix uart3 CTS/RTS pinmuxing since pins were swapped.

Link to v1: https://lore.kernel.org/all/20260930103425.2315286-1-primoz.fiser@norik.com/

Changes in v2:
- Drop patch #1 from v1 
- Add new patch #2 (CTS/RTS swap fix)

[PATCH v2 1/2] ARM: dts: imx6qdl-phytec-mira: Add touchscreen-inverted properties

[Primoz Fiser]

Since commit 888e5fad9b78 ("Input: stmpe - add axis inversion and
swapping capability") we can handle touchscreen x- and y-axis inversion
directly in the kernel instead of user-space on phyBOARD-Mira-i.MX6.

[PATCH v2 2/2] ARM: dts: imx6qdl-phytec-mira: Fix uart3 CTS/RTS pinmuxing

[Primoz Fiser]

The pin muxing of the UART3 CTS and RTS pins on the phyBOARD-Mira is
wrong. They are swapped. Pad EIM_EB3 has to be muxed as RTS and pad
EIM_D23 as CTS.

Shouldn't they have a Fixes tag, then?

For patch #1 it think it is pointless because those properties didn't
exist until aforementioned commit 888e5fad9b78 ("Input: stmpe - add axis
inversion and swapping capability"). So it is an addition not a fix as
commit message suggests.

For patch #2 I could add:

Fixes: 800d595151bb ("ARM: dts: imx6: Add initial support for
phyBOARD-Mira")

in v3 if you want?

BR,
Primoz
