2019-01-02rockchip: rk3399: Add improved pinctrl driver.Christoph Muellner
The current pinctrl driver for the RK3399 has a range of qulity issues. E.g. it only implements the .set_state_simple() callback, it does not parse the available pinctrl information from the DTS (instead uses hardcoded values), is not flexible enough to cover devices without 'interrupt' field in the DTS (e.g. PWM), is not written generic enough to make code reusable among other rockchip SoCs... This patch addresses these issues by reimplementing the whole driver from scratch using the .set_state() callback. The new implementation covers all featurese of the old code (i.e. it supports pinmuxing and pullup/pulldown configuration). This patch has been tested on a RK3399-Q7 SoM (Puma).

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
