pinctrl: pinconf-generic: Allow driver to specify DT params
Additionally to the generic DT parameters, allow drivers to provide driver-specific DT parameters to be used with the generic parser infrastructure. To achieve this 'struct pinctrl_desc' is extended to pass custom pinconf option to the core. In order to pass this kind of information, the related data structures - 'struct pinconf_generic_dt_params', 'pin_config_item' - are moved from pinconf internals to the pinconf-generic header. Additionally pinconfg-generic is refactored to not only iterate over the generic pinconf parameters but also take the parameters into account that are provided through the driver's 'struct pinctrl_desc'. In particular 'pinconf_generic_parse_dt_config()' and 'pinconf_generic_dump' helpers are split into two parts each. In order to have a more generic helper that can be used to process the generic parameters as well as the driver-specific ones. v2: - fix typo - add missing documentation for @conf_items member in struct - rebase to pinctrl/devel: conflict in abx500 - rename _pinconf_generic_dump() to pinconf_generic_dump_one() - removed '_' from _parse_dt_cfg() - removed BUG_ONs, error condition is handled in if statements - removed pinconf_generic_dump_group() & pinconf_generic_dump_pin helpers - fixed up corresponding call sites - renamed pinconf_generic_dump() to pinconf_generic_dump_pins() - added kernel-doc to pinconf_generic_dump_pins() - add kernel-doc - more verbose commit message Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
