* pinctrl: Explicitly include correct DT includesRob Herring2023-07-201-2/+2
| | | | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

* pinctrl: imx: use struct imx_pinctrl_soc_info as a constStefan Agner2018-01-111-2/+1
| | | | | | | | | | | | | | | | For some SoCs the struct imx_pinctrl_soc_info is passed through of_device_id.data which is const. Most variables are already const or otherwise not written. However, some fields are modified at runtime. Move those fields to the dynamically allocated struct imx_pinctrl.

| | | | | | | | | | | | | | Various IMX platforms may have different imx_pmx_ops.gpio_set_direction implementations, so let's make it platform specific callbacks instead of the fixed common one. Currently only VF610 platform implements it. No function level changes.

* pinctrl: imx: add soc specific mux_mode mask and shift propertyDong Aisheng2017-05-221-0/+2
| | | | | | | | | | | | | | | | | | MX7ULP MUX mode mask and shift bit is different from VF610. Let's make it a platform specific property for the later easy of adding MX7ULP support. One trick in exist code that Vybrid hardcoded the config part as 0xffff because its mux_config register BIT[15-0] are all configs part. But it's not true in ULP, so use mux_mask instead to address the difference.

* pinctrl: vf610: make it explicitly non-modularPaul Gortmaker2016-06-291-10/+0
| | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/pinctrl/freescale/Kconfig:config PINCTRL_VF610 drivers/pinctrl/freescale/Kconfig: bool "Freescale Vybrid VF610 pinctrl driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init wasn't in use by this driver, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

* pinctrl: freescale: add ZERO_OFFSET_VALID flag for vf610 pinctrlShawn Guo2015-12-101-1/+1
| | | | | | | | | | | | | | | | | | | To support i.MX7D Low Power State Retention IOMUXC, commit e7b37a522aa9 ("pinctrl: freescale: imx: allow mux_reg offset zero") changes the way of zero mux_reg offset support with a new flag ZERO_OFFSET_VALID. But, unfortunately, it forgot to add this flag for vf610 pinctrl which has zero mux_reg offset be valid as well, and hence breaks the vf610 support. Fix the regression by adding flag ZERO_OFFSET_VALID for vf610 pinctrl driver.

* pinctrl: imx: detect uninitialized pinsStefan Agner2014-09-231-1/+1
| | | | | | | | | | | | | | 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.
