pinctrl: tegra: add support for rcv-sel and drive type
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.
