2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-05-18arm: Don't include common.h in header filesSimon Glass
It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-03-03video: omap: add support for DM/DTSDario Binacchi
Update the driver to support the device tree and the driver model. Timings and panel parameters are now loaded from the device tree. The DM code replaces the am335x_lcdpanel structure with tilcdc_panel_info taken from the linux kernel, as well the management of additional parameters not covered in the legacy code. In addition, the am335x_lcdpanel structure contains parameters and operations that were probably a requirement of the board for which this driver was developed and which, however, were not developed in the linux kernel. All this led to rewrite th DM controller initialization code, except for the pixel clock setting that is executed in a function created in a previous patch with code taken from the legacy am335xfb_init. The patch has been tested on a custom board with u-boot 2018.11-rc2 and the following device-tree configuration: panel { compatible = "ti,tilcdc,panel"; pinctrl-names = "default"; pinctrl-0 = <&lcd_enable_pins>; enable-gpios = <&gpio0 31 0>; backlight = <&backlight>; status = "okay"; u-boot,dm-pre-reloc; panel-info { ac-bias = <255>; ac-bias-intrpt = <0>; dma-burst-sz = <16>; bpp = <16>; fdd = <0x80>; sync-edge = <0>; sync-ctrl = <1>; raster-order = <0>; fifo-th = <0>; }; display-timings { native-mode = <&timing0>; timing0: 800x480 { hactive = <800>; vactive = <480>; hback-porch = <46>; hfront-porch = <210>; hsync-len = <20>; vback-porch = <23>; vfront-porch = <22>; vsync-len = <10>; clock-frequency = <33000000>; hsync-active = <0>; vsync-active = <0>; }; }; }; Signed-off-by: Dario Binacchi <dariobin@libero.it> Tested-by: Dario Binacchi <dariobin@libero.it>

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

The board_early_init_f() inits clock before initing pinmux. However, the clock configuration code might need to adjust PMIC settings of a PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C bus pin muxing is not configured before attempting to communicate with the PMIC, the communication will silently fail and the prcm_init() may configure fast enough CPU clock that the default voltage provided by the PMIC would be insufficient and the platform would become unstable.

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>
