Series-changes: 2
- remove RFC
- fixed Codingstyle errors, therefore new patch
powerpc, mpc83xx: fix codingstyle issues for qe_io.c
- moved DM part to drivers/pinctrl
Commit-notes:
Open questions / discussion:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This should be removed if all boards are converted to
DM/DTS.
- Unfortunately linux DTS does not use "pinctrl-"
properties, instead "pio-handle" properties.
Even worser old U-Boot code initializes all pins
defined in "const qe_iop_conf_t qe_iop_conf_tab[]"
table in board code. As linux does the same I decided
to also scan through all subnodes containing "pio-map"
property and initialize them too.
The proper solution would be to check for "pio-handle"
when a device is probed.
