Subject: [RFC v2 1/3] pinctrl: imx: remove const qualifier of imx_pinctrl_soc_info
Otherwise can't dynamically update fields such as ngroups which can
change over time (with a dt-overlay for instance).
Signed-off-by: Gary Bisson <gary.bisson@...ndarydevices.com>

Hi all,
If this patch isn't applied the compiler gives errors like:
error: increment of member ‘nfunctions’ in read-only object
Regards,
Gary
