2021-12-27video: mxsfb: fix clk_get_by_name() return value checkGiulio Benetti1-2/+2
If clk_get_by_name() returns 0 it means it executed successfully while now we consider it as an error. So let's check if return value is negative to be an error. Otherwise this prevents "axi" and "disp_axi" to be enabled. Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>

2021-06-09video: mxsfb: add enabling of "disp_axi" clockGiulio Benetti1-0/+11
Some SoC needs "disp_axi" clock to be enabled, so let's try to retrieve it and enabling. If it fails it gives only a debug(), but this clock as well as "axi" clock is not mandatory. Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>
2021-06-09video: mxsfb: add enabling of "axi" clock other than "per" clockGiulio Benetti1-7/+18
On some SoC mxsfb needs more than one clock gate(actual "per" clock). So let's introduce "axi" clock that can be provided but it's not mandatory. This is inspired from linux mxsfb driver. Also let's rename "per" clock to "pix" clock for compatibility with already existing .dts lcdif nodes implementation. Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it.

2020-02-06dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-11-12video: mxsfb: Configure the clock after eLCDIF resetFabio Estevam1-3/+3
Running stress reboot test on a i.MX6ULL evk board with a custom LCD can lead to splash screen failure (black screen). After comparing the eLCDIF initialization with the Linux kernel driver, it was noticed that the eLCDIF reset is the first operation that needs to be done. So do like the eLCDIF Linux driver and move the eLCDIF clock frequency configuration after the eLCDIF reset and just prior to setting the RUN bit. With this change applied, no more black screen issues has been found during overnight reboot stress tests. Signed-off-by: Fabio Estevam <festevam@gmail.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.
