Axel Lin 2ffdc9a648 pwm: Remove a redundant error message when devm_request_and_ioremap fails
The implementation in devm_request_and_ioremap() already shows error message,
so no need to show dev_err again if devm_request_and_ioremap() fails.

Thierry Reding 0134b932a0 pwm: Add NVIDIA Tegra SoC support
This commit adds a generic PWM framework driver for the PWFM controller
found on NVIDIA Tegra SoCs. The driver is based on code from the
Chromium kernel tree and was originally written by Gary King (NVIDIA)
and later modified by Simon Que (Chromium).
