* | pinctrl: fix Kconfig dependenciesSascha Hauer2014-09-154-12/+29
|/ | | | | | | | | | | | | | | | | - Remove OFDEVICE dependency from PINCTRL. It won't do much then, so add a comment to Kconfig when PINCTRL is selected without OFDEVICE - Let Architectures only select PINCTRL instead of the particular driver. Change the drivers to 'default y if $SOC' to make sure the drivers are still compiled if the corresponding SoC is selected This fixes Kconfig warnings like: warning: (PINCTRL_ARMADA_370 && PINCTRL_ARMADA_XP && PINCTRL_DOVE && PINCTRL_KIRKWOOD) selects PINCTRL which has unmet direct dependencies (OFDEVICE) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | Instead of requiring a device pointer, add a functions to select the pinctrl state based on a device node. The AM33xx cpsw devicetree description has several subdevices with pinctrl information attached to them. In barebox we do not handle the subdevices as distinct devices, so the pinctrl is never configured correctly and the mdio bus subdevice stops working. This patch makes it possible to configure the pinctrl without having a device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | This switches the iomux-v3 (found on i.MX25,35,51,53,6) to pinctrl support. The old SoC specific API is kept for compatibility. The pinctrl devicetree support is enabled automatically when OFDEVICE support is available. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add initial pinctrl supportSascha Hauer2013-04-233-0/+162
This is a massively stripped down pinctrl support. The upper API consists of only of: int pinctrl_select_state(struct device_d *dev, const char *state); This is used to setup the pinmux for a device to a certain state. This function normally does not need to be called manually. The device core will setup the default state before probing a device. The pinctrl core has the job of handling the devicetree. It parses the pinctrl phandles for a device from devicetree, finds the correct pinctrl device and calls its set_state callback with the pinctrl setup device node. The simplicity of this pinctrl framework comes from the fact that we: - Limit usage to devicetree only for now. For non devicetree use the old legacy SoC specific APIs still can be used. - Do not parse the devicetree into internal data structures which are used by the drivers later. This adds the overhead that we may parse the devicetree multiple times for more dynamic setups, but on the other hand we do not need to parse devices from the devicetree we don't use in barebox - Do not detect resource conflicts. Since the framework mainly is a devicetree parser this would be hard to implement. It should be easy for board maintainers to avoid resource conflicts though.
