This moves the implementation of *_pinmux_init() into a single location. The board-specific pinmux data is left in each board's own file. This will allow future changes that set up the pinmux in a more complex fashion to do so without duplicating that code in each board's pinmux file.

Pin group PTA does not support function RSVD3. However, the current pinmux driver doesn't check this when setting RSVD functions, and ends up writing 3 to the HW register. 3 is actually represented by function GMI, so update the pinmux table to request that instead in order to obtain the same register programming without requesting invalid configurations.

Rather than modifying seaboard_pinmux[] using ventana_pinmux[], split seaboard_pinmux[] into common_pinmux[] and seaboard_pinmux[], and then actually apply common_pinmux[] always, followed by the appopriate one of seaboard_pinmux[] or ventana_pinmux[].

The Harmony pinmux table is already set up to mux the PCIe signals onto the appropriate pin groups. Don't manually fiddle with the pinmux in the Harmony PCIe setup code. Merge note: This will have a merge conflict with Peter De Schrijver's "arm/tegra: prepare pinmux code for multiple tegra variants" due to context. When merging the two, make sure to also remove the include of <mach/pinmux-tegra20.h> that his patch added, since it's no longer needed after this patch.

The pinctrl device name is included in the pinctrl map table, and used as a parameter to pin_config_*() functions. Hence, it must be the same for non-DT and DT kernels. Add AUXDATA to cause this. The GPIO device name will be used by the pinmux/GPIO initialization code in a later patch, and needs to stay constant.

*_pinmux_init() register the GPIO and pinmux devices so that they're ready before any other device needs them. *_pinmux_init() are also called by board-dt.c in order to set up the GPIO and pinmux configurations. In this case, if we register the devices, they end up being probed once due to this registration, and a second time due to a device-tree node (or vice-versa). The second probe fails since the memory regions are already requested. Besides, we don't actually want the duplicated devices. To avoid this duplicate registration, modify *_pinmux_init() to check whether it's running on a DT machine. If not, register the pinmux devices. If so, don't register them. Finally, modify board-dt.c to call the *_pinmux_init() after all devices have been instantiated from device-tree. This allows the GPIO and pinmux devices to be instantiated and initialized before calling functions to configure the hardware. This has one disadvantage: The pinmux and GPIO initialization now happens after /all/ devices are instantiated, rather than after just gpio and pinmux but before anything else. So the correct HW configuration is not in place when e.g. the SD/MMC device is probed. Long-term, this should be solved by doing both: a) Initializing the HW state from DT nodes during GPIO and pinmux device probe. b) Using the deferred driver probe mechanism, so that drivers can defer their probe until after the gpio and pinmux drivers have probed. v2: s/int is_dt/bool is_dt/ v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing an explicit parameter into the function from outside.

Without this, the PMC continually detects an interrupt when the PMU_IRQ line is high, causing the tps6686x IRQ handler thread to hog an entire CPU. This change was originally written by Wei Ni <wni@nvidia.com> for Seaboard in the ChromeOS kernel.

Use ioremap to obtain access to registers instead of using static mappings. This reduces the number of users of the static mappings, which will eventually allow them to be removed. Note that on Tegra30, the number of register "banks" will decrease to 2, and the packing of specific bits into registers will change significantly. That's why this change adds the "*_bank" fields to the pingroup tables, rather than implementing some more hard-coded scheme. Also, completely remove the implementation of suspend/resume; Tegra doesn't yet support suspend/resume, and the implementation is complex for the general pinmux driver: * Not all registers are used within each bank, so we probably shouldn't just iterate over every register in the bank, and save/restore it, since that would mean touching undefined registers. * Registers are shared between pingroups, so we can't simply iterate over each pingroup, and save/restore the registers it uses. It'd probably be best have probe() calculate a bitmask of actually-used registers for each bank, and have suspend/resume iterate over those bitmaps. Oh, and Real Soon Now, I should be looking into converting this driver to the new pinmux/pinctrl subsystem, so I didn't want to put too much work into the current incarnation. v2: s/space/bank/ to match comments on reg_* fields in pinmux.h.
