Yeah, but I believe Tegra 2 aka T20 with its rather special pin group
arrangement has never really been properly converted to using
funcmux_select() other than for DISP, KBC, NDFLASH, SDMMC, SPI and USB.

As a matter of fact even the Tegra video driver uses pinmux_set_func()
which BTW is hard-coded to a specific PWM in there!

[user at host u-boot] $ cat drivers/video/tegra.c | grep PWM
STAGE_PWM,
debug("%s: Unable to request PWM channel\n", __func__);
case STAGE_PWM:
/* Enable PWM at 15/16 high, 32768 Hz with divider 1 */
pinmux_set_func(PMUX_PINGRP_GPU, PMUX_FUNC_PWM);
