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).

2019-07-11arm: mach-omap2: am33xx: Init pinmux before clockMarek Vasut
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>

Parse these registers during SPL boot and jump to the kernel resume vector if the device is waking up from RTC-only modewith DDR in Self-refresh. The RTC scratch register layout used is: SCRATCH0 : bits00-31 : kernel resume address SCRATCH1 : bits00-15 : RTC magic value used to detect valid config SCRATCH1 : bits16-31 : board type information populated by bootloader During the normal boot path the SCRATCH1 : bits16-31 are updated with the eeprom read board type data. In the rtc_only boot path the rtc scratchpad register is read and the board type is determined and correspondingly ddr dpll parameters are set. This is done so as to avoid costly i2c read to eeprom.

The ti816x/am389x SoC is the first generation in what U-Boot calls the "am33xx" family. In the first generation of this family the DDR initialization sequence is quite different from all of the subsequent generations. Whereas with ti814x (second generation) we can easily work the minor differenced between that and am33xx (third generation), our attempts to do this for ti816x weren't sufficient. Rather than add a large amount of #ifdef logic to make this different sequence work we add a new file, ti816x_emif4.c to handle the various required undocumented register writes and sequence and leverage what we can from arch/arm/mach-omap2/am33xx/ddr.c still. As DDR2 has similar problems today but I am unable to test it, we drop the DDR2 defines from the code rather than imply that it works by leaving it. We also remove a bunch of other untested code about changing the speed the DDR runs at. Signed-off-by: Tom Rini <trini@konsulko.com>
