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>
before relocation pinctrl data BSS is overlapping DT area, when .data is using uninitialized global variable, imx6_pinctrl_soc_info. So assign them flags ZERO_OFFSET_VALID to prevent BSS overlap Suggested-by: Lokesh Vutla <lokeshvutla@ti.com> Reported-by: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
To i.MX7ULP, we need to create two info instances for iomux0 and iomux1 respectively, otherwise iomuxc0/1 will share one info instance and use one base, because imx_pinctrl_probe will use info to store base address and etc. But iomuxc0/1 actually have different base address.

when using SHARE_MUX_CONF_REG, wrong mask is used for writing config value, which causes mux value is cleared. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Simon Glass <sjg@chromium.org> Cc: Stefano Babic <sbabic@denx.de>
It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>
Each time set_state is called, a new piece memory will be allocated for pin_data, but not freed, this will incur memory leak. When error, the devm API could not free memory automatically. So need call devm_kfree when error.

At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

Add CX9020 board based on mx53loco. Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse serial_mxc with DTE and prepare for device tree migration of other functions and imx53 devices. The CX9020 differs from i.MX53 Quick Start Board by: - use uart2 instead of uart1 - DVI-D connector instead of VGA - no audio - CCAT FPGA connected to emi - enable rtc Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>
