* pinctrl: tegra: add support for rcv-sel and drive typePritesh Raithatha2013-01-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | NVIDIA's Tegra114 added two more configuration parameter in pinmux i.e. rcv-sel and drive type. rcv-sel: Select between High and Normal VIL/VIH receivers. RCVR_SEL=1: High VIL/VIH RCVR_SEL=0: Normal VIL/VIH drv_type: Ouptput drive type: 33-50 ohm driver: 0x1 66-100ohm driver: 0x0 Add support of these parameters to be configure from DTS file. Tegra20 and Tegra30 does not support this configuration and hence initialize their pinmux structure with reg = -1. Originally written by Pritesh Raithatha. Changes by ldewangan: - remove drvtype_width as it is always 2. - Better describe the change.

* Drivers: pinctrl: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* pinctrl: tegra: refactor probe handlingStephen Warren2012-04-181-3/+37
| | | | | | | | | | | | | | Rather than having a single tegra-pinctrl driver that determines whether it's running on Tegra20 or Tegra30, instead have separate drivers for each that call into utility functions to implement the majority of the driver. This change is based on review feedback of the SPEAr pinctrl driver, which had originally copied to Tegra driver structure. This requires that the two drivers have unique names. Update a couple spots in arch/arm/mach-tegra for the name change. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: add a driver for NVIDIA TegraStephen Warren2012-03-061-0/+3726
This adds a driver for the Tegra pinmux, and required parameterization data for Tegra20 and Tegra30. The driver is initially added with driver name and device tree compatible value that won't cause this driver to be used. A later change will switch the pinctrl driver to use the correct values, switch the old pinmux driver to be disabled, and update all code that uses the old pinmux APIs to use the new pinctrl APIs.
