pinctrl: nomadik: move all Nomadik drivers to subdir

2014-07-11T13:01:35+00:00

We have a bunch of Nomadik family pin control drivers, so let's move them into their own subdirectory. Signed-off-by: Linus Walleij

pinctrl: nomadik: move platform data handling into driver

2013-11-26T20:01:58+00:00

This decomissions the platform data header (which is no longer in use after the systems using this driver were switched to a pure device-tree config path) and merges the result into the driver file or local driver header. Signed-off-by: Linus Walleij

pinctrl/nomadik: support other alternate-C functions

2012-10-10T06:36:59+00:00

Upgrade nomadik pinctrl driver to enable selection of other alternate-C[1-4] functions on some specific ux500 SoC pins. Handling of those functions is done thanks to PRCM GPIOCR registers. This was previously managed in PRCMU driver and it was not really convenient. Idea is to provide a common way to control all alternate functions. Note that this improvement does not support the old-fashioned way used to control nomadik pins, namely the "nmk_config_pin()" function and its derivatives.

pinctrl/nomadik: implement pin multiplexing

2012-05-11T09:14:16+00:00

Implements basic pinmux for the Nomadik pin controller. The plan is to split the existing singular pin config interface nmk_config_pin(), nmk_config_pins(), that will configure muxing and other settings at the same time, into two interfaces by splitting the code in pinmux and pinctrl and eventually deleting the old interface and its helper functions when all users are gone. nmk_gpio_set_mode() and nmk_gpio_get_mode() are two older interfaces for just configuring muxing/altfunctions that will also be replaced in the end. We take some extra care to handle the glitch-avoidance here, but it is simpler now since there is only one altsetting per pingroup so we know immediately if we need to avoid altfunc C glitches for a certain group. As part of the makeover implement the .request() and .free() calls on the GPIO chips and have them call back into the pinctrl layer to reserve GPIOs. ChangeLog v1->v2: - Rebased on pinctrl-mergebase-20120418 so we get the latest driver infrastructure where function count is done by a fixed value and we can drop a few range checks since this is now handled by the core. - Include a GPIO muxing hunk erroneously part of the pin config patch.

pinctrl/nomadik: basic Nomadik pinctrl interface

2012-05-11T09:14:14+00:00

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 Signed-off-by: Linus Walleij
