* pinctrl: imx: attach iomuxc device to gpr sysconPhilipp Zabel2016-03-081-0/+1
| | | | | | | | | | | | | | | Commit bdb0066df96e ("mfd: syscon: Decouple syscon interface from platform devices") added the possibility to register syscon devices without associated platform device. This also removed regmap debugfs facilities, which don't work without a device. This patch associates the syscon regmap that handles the IOMUX controller's general purpose registers with the pinctrl device so that the GPR registers appear in the regmap debugfs directory again. For example, on i.MX6Q the GPR registers now can be read from /sys/kernel/debug/regmap/20e0000.iomuxc-gpr/registers.

* pinctrl: freescale: imx: fix system crash if enable two pinctl instancesRobin Gong2015-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix system chrash caused by groups whose number is smaller than the number of groups of the last pinctl instance which is not initialized. iMX7D supports two iomux controllers (iomuxc-lpsr and iomuxc) on probing the second instance (iomuxc) the chrash below occurs.

* pinctrl: imx: detect uninitialized pinsStefan Agner2014-09-231-4/+3
| | | | | | | | | | | | | | The pinctrl driver initialized the register offsets for the pins with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl mux register. So far, this was solved using the ZERO_OFFSET_VALID flag which allowed offsets of 0. However, this does not allow to verify whether a pins struct imx_pmx_func was initialized or not. Use signed offset values for register offsets and initialize those with -1 in order to detect uninitialized offset values reliable.

This moves all the Freescale-related drivers (i.MX and MXS) to its own subdirectory to clear the view.
