To establish a connection between GPIO controllers and pin multiplexor
controller add gpio-ranges properties to all GPIO controllers found
on iMX50, iMX6Q/D, iMX6DL/S, iMX6SL, iMX6SX, iMX6UL and iMX7D/S
SoCs. The change was done after human parsing of output from

% gawk -n '{ sub(/.*__/, ""); if ($1 ~ "^GPIO") print $1, $2/4}' imxXX-pinfunc.h | sort -n

Changes from v2 to v3:
* squashed patches against particular SoCs into one single change
* removed empty lines preceding to the added gpio-ranges property

Changes from v1 to v2:
* in copy-pasted commit messages corrected SoC names

Applied, thanks.

When looking at doing the same for i.MX35 there are a few pin pairs that
are driven by the same GPIO, e.g.:

	$ grep GPIO3_9 imx35-pinfunc.h 
	#define MX35_PAD_CTS1__GPIO3_9					0x194 0x5d8 0x918 0x5 0x0
	#define MX35_PAD_FEC_COL__GPIO3_9				0x2ec 0x750 0x918 0x5 0x1

With this it's not possible to correctly add a gpio-ranges, right?

i.MX1, i.MX21, i.MX25, i.MX27 and i.MX53 could benefit from such a
change though. i.MX35 and i.MX51 have duplicates.

Best regards
Uwe

this is an interesting exceptional case, I don't think that pinctrl
and gpio subsystems are ready to handle it.

If both pads are muxed to the same GPIO, then I presume on output it
behaves like a tee, but do you know what would be the input value,
if one line is driven high and another one is low?

I keep my hands off it, because I don't have any boards powered by
these SoCs to be able to test the change. FWIW I hold one i.MX31
powered board from old times, but I see that i.MX31 has poor DTS
support in general, there is no GPIO controller device node to
add the property.

That depends on the setting of register
IOMUXC_GPIO3_IPP_IND_G_IN_9_SELECT_INPUT at offset 0x918 (third value in
the constants). If it's 0 (fifth value) the value at MX35_PAD_CTS1 is
read, if it's 1 MX35_PAD_FEC_COL is used.

Best regards
Uwe
