• 348d1bf75   pinctrl: tegra: add support for rcv-sel and drive type ... Browse Code »

  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.

  Now that Tegra's pinmux is configured solely from device tree, there's
  no need for the pinconf types to be defined in arch/arm/mach-tegra/.
  Move it into the pinctrl directory to clean up mach-tegra, as a pre-
  requisite for single-zImage.

  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.

• 971dac712   pinctrl: add a driver for NVIDIA Tegra ... Browse Code »

  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.
