[PATCH] ARM: dts: imx25-pinfunc: add MX25_PAD_KPP_ROW3__UART1_RI

[Uwe Kleine-König]

Funny side note: When uart1 is used in dte mode (where RI is an input)
the RIIN bit in uart1's USR2 register reflects the input level of
MX25_PAD_KPP_ROW3 even if this pad is muxed to a different function.
The same seems to hold for some other pads, too.

Hello,

I think the appropriate action for the "funny" side note is that we must
introduce dt-properties like

	fsl,mask-ri;

or something similar (maybe positive logic?) that prevents an uart1 RI irq
whenever uart3.CTS toggles.

Best regards
Uwe
