There is quite a bit of net addition of code for each platform being added to the pinctrl subsystem. But the payback comes later when adding new boards can be done by only providing new device trees instead."

| | * pinctrl/nomadik: implement pin configurationLinus Walleij2012-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements the pin configuration interface for the Nomadik pin controller. As part of the exercise we add a bit in the pin_cfg_t for the Nomadik pinctrl driver that indicates if the pin should be forced into GPIO mode. This is not done to go behind the back of the GPIO subsystem, but to ensure that default modes can be set by hogs on boot and system suspend/resume states. It was used implicitly by the old code defining all config settings and modes in a single config word but we now have a split between pinmux and pinconf leading to the need to have this. We also add a bit for explicitly setting sleepmode of the pin. This was previously handled by custom calls with the _sleep() suffix, but we now have one single interface into the configuration so we replace this with a bit indicating that the pin shall be configured into sleep mode. Some of the configuration can be refactored later to use less custom fields on the pin_cfg_t but we are currently leaving the old function calls in place so we stay compatible. ChangeLog v1->v2: - Drop a hunk changing pinmuxing for GPIO and move it over to the preceding pinmux patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a scratch pin control interface to the Nomadik pinctrl driver, and defines the pins and groups in the DB8500 ASIC. We define GPIO ranges to cover the pins exposed. The DB8500 has more pins than this but we restrict the driver to the pins that can be controlled from the combined GPIO and pin control hardware to begin with. ChangeLog v1->v2: - Base on the latest pinctrl development from pinctrl-mergebase-20120418 so we can get rid of legacy group count mechanism. Also drop the range checks for group index, this is handled by the core now. Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

That said, the mxs device drivers can only get pinctrl state from pinctrl subsystem when the drivers get probed from device tree. Before converting the whole mxs platform support over to device tree, we need to enable pinctrl dummy states for those non-DT board files to ensure the pinctrl API adopted by mxs device drivers will work for both DT and non-DT probe. Instead of calling pinctrl_provide_dummies() directly in every board file, the patch introduces soc specific calls mx23_soc_init() and mx28_soc_init() for boards' .init_machine hook to invoke, so that any soc specific setup for non-DT boot only can be added there.

Ventana's pin mux table needed some edits on top of the basic format conversion, since some mux options that were previously marked as reserved are now valid in the new pinctrl driver. Attempting to use the old reserved names will result in a failure. Specifically, groups lpw0, lpw2, lsc1, lsck, and lsda were changed from function rsvd4 to displaya, and group pta was changed from function rsvd2 to hdmi. All boards' pin mux tables needed some edits on top of the based format conversion, since function i2c was split into i2c1 (first general I2C controller) and i2cp (power I2C controller) to better align function definitions with HW blocks. Due to the split of mux tables into pure mux and pull/tristate tables, many entries in the separate Seaboard/Ventana tables could be merged into the common table, since the entries differed only in the portion in one of the tables, not both. Most pin groups allow configuration of mux, tri-state, and pull. However, some don't allow pull configuration, which is instead configured by new groups that only allow pull configuration. This is a reflection of the true HW capabilities, which weren't fully represented by the old pinmux driver. This required adding new pull table entries for those new groups, and setting many other entries' pull configuration to TEGRA_PINCONFIG_DONT_SET.

Tied to both the Emma Mobile EV2 and the KZM9D board due to the need to switch on board in platsmp.c and the newly introduced need for static mappings. The static mappings are needed to allow hardware acces early during boot when SMP is initialized. This early requirement forces us to also map in the SMU registers.
