pinctrl: tegra: Duplicate pinmux functions table The function table is filled with group information based on other instance-specific data at runtime. However, the function table can be shared between multiple instances, causing the ->probe() function for one instance to overwrite the table of a previously probed instance. Fix this by sharing only the function names and allocating a separate function table for each instance.

pinctrl: tegra: Add bitmask support for parked bits Some pin groups have park bits for multiple pins in one register. Support this by turning the parked bit field into a parked bitmask field. If no parked bits are supported, the bitmask can be 0. Update the pingroup table on Tegra210, which is the only generation where this is supported, with the parked bitmask.

pinctrl: tegra: Move drivers registration to arch_init level There is a bug in regards to deferred probing within the drivers core that causes GPIO-driver to suspend after its users. The bug appears if GPIO-driver probe is getting deferred, which happens after introducing dependency on PINCTRL-driver for the GPIO-driver by defining "gpio-ranges" property in device-tree. The bug in the drivers core is old (more than 4 years now) and is well known, unfortunately there is no easy fix for it. The good news is that we can workaround the deferred probe issue by changing GPIO / PINCTRL drivers registration order and hence by moving PINCTRL driver registration to the arch_init level and GPIO to the subsys_init.

pinctrl: tegra: define GPIO compatible node per SoC Tegra 2 uses a different GPIO controller which uses "tegra20-gpio" as compatible string. Make the compatible string the GPIO node is using a SoC specific property. This prevents the kernel from registering the GPIO range twice in case the GPIO range is specified in the device tree.

pinctrl: tegra: clean up modular vs. non-modular distinctions None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get similar changes, so they are handled in batch. We remove module.h from code that isn't doing anything modular at all; if they have __init sections, then replace it with init.h. A couple drivers have module_exit() code that is essentially orphaned, and so we remove that. Quite a few bool drivers (hence non-modular) are converted over to to builtin_platform_driver(). Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

pinctrl: tegra: avoid parked_reg and parked_bank NVIDIA's Tegra210 support the park bit to make pinmux configuration enable/disable. If parked bit is 1 then configuration does not apply and if it is 0 then pinmux configuration applies. This is to support to avoid any glitch in pinmux configurations. The parked bit is part of mux register and mux bank and hence it is not required to have member for the parked_reg and parked bank very similar to other bit field of the same register. Remove the need of the parked register and parked bank and get whether parked function supported or not by parked_bit. This is to make the parked bit handling same as other fields of mux registers.

pinctrl: tegra: clear park bit for all pins Parking bits might not be cleared by the bootloader properly (if for instance it doesn't use the device configured by that pin). Clear the park bits for all the pins during pinctrl probe. This is present on T210 platforms but not earlier ones, so for earlier generations, set parked_reg = -1 to disable. The park bit is used to prevent glitching when reprogramming pinctrl registers.
