2013-05-15pinctrl/lantiq: Free mapping configs for both pin and groupsLaurent Pinchart
When creating mappings from DT both pin config and group config mappings are allocated. Free them both when destroying the mappings.

2013-03-07pinctrl: Declare operation structures as constLaurent Pinchart
The pinconf, pinctrl and pinmux operation structures hold function pointers that are never modified. Declare them as const. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-02-05pinctrl/lantiq: fix pin number in ltq_pmx_gpio_request_enableJohn Crispin
The mapping logic inside ltq_pmx_gpio_request_enable() was broken. This only effected Falcon SoC. Signed-off-by: Thomas Langer <thomas.langer@lantiq.com> Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-02-05pinctrl/lantiq: add pin_config_group_set supportJohn Crispin
While converting all the boards supported by OpenWrt to OF I noticed that this feature is missing. Adding it makes the devicetrees more readable. Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-11-11pinctrl: lantiq: Staticize non-exported symbolsAxel Lin
Both ltq_pinctrl_dt_node_to_map() and ltq_pinctrl_dt_free_map() are not referenced outside of this file. Make them static. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: John Crispin <blogic@openwrt.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-11-11pinctrl: lantiq: Remove ltq_pmx_disable() functionAxel Lin
Current code adds empty ltq_pmx_disable() because pinmux_check_ops() requires this callback to be defined. This is not required since commit 02b50ce4cb1 "pinctrl: make pinmux disable function optional". Thus remove ltq_pmx_disable() function.

2012-09-13OF: pinctrl: MIPS: lantiq: implement lantiq/xway pinctrl supportJohn Crispin
Implement support for pinctrl on lantiq/xway socs. The IO core found on these socs has the registers for pinctrl, pinconf and gpio mixed up in the same register range. As the gpio_chip handling is only a few lines, the driver also implements the gpio functionality. This obseletes the old gpio driver that was located in the arch/ folder.
