* video: sunxi: de2: switch to public uclass functionsJernej Skrabec2021-04-241-19/+10
| | | | | | | | | | | Currently DE2 driver uses functions which are defined in internal headers. They are not meant to be used outside of uclass framework. Switch DE2 driver to public ones. This has additional benefit that device_probe doesn't need to be called manually.

* video: sunxi: dw-hdmi: read source_id laterJernej Skrabec2021-04-241-4/+2
| | | | | | | | | | | | There is no real need to read source_id at probe time. It also doesn't make sense to store it in driver private data since it's already stored in class platform data. While this looks like cleanup (and it is), it's also important for DE2 driver rework because this info will be filled later (after probe is already executed).

* video: sunxi: Use DW-HDMI hpd functionJernej Skrabec2021-04-241-28/+6
| | | | | | | | | | | | | | It turns out that there are two ways how hot plug detection can be done. One is standard way for DW HDMI controller - checking bit 2 in 0x3004 register. Another way is applicable only to Allwinner custom PHY - by checking bit 19 in register 0x10038. Both methods are equally good as far as we know. Use standard method in order to reduce amount of custom code.

* video: sunxi_display: Convert to DM_VIDEOJagan Teki2021-03-031-115/+153
| | | | | | | | | | | | | | | | | | | | | | | | | DM_VIDEO migration deadline is already expired, but around 80 Allwinner boards are still using video in a legacy way: ===================== WARNING ====================== This board does not use CONFIG_DM_VIDEO Please update the board to use CONFIG_DM_VIDEO before the v2019.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ==================================================== Convert the legacy video driver over to the DM_VIDEO framework. This is a minimal conversion: it doesn't use the DT for finding its resources, nor does it use DM clocks or DM devices for the outputs (LCD, HDMI, CVBS). Tested in Bananapi M1+ Plus 1920x1200 HDMI out.

* dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()Simon Glass2021-01-053-3/+3
| | | | | | | | | | | | | | | | | | | | The current macro is a misnomer since it does not declare a device directly. Instead, it declares driver_info record which U-Boot uses at runtime to create a device. The distinction seems somewhat minor most of the time, but is becomes quite confusing when we actually want to declare a device, with of-platdata. We are left trying to distinguish between a device which isn't actually device, and a device that is (perhaps an 'instance'?) It seems better to rename this macro to describe what it actually is. The macros is not widely used, since boards should use devicetree to declare devices. Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is declaring a new driver_info record, not a device. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-132-2/+2
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module.

* sunxi: video: HDMI: Fix clock setupJernej Skrabec2019-03-281-25/+37
| | | | | | | | | | | | | | | | | | | | | | Currently, HDMI driver doesn't consider minimum and maximum allowed rate of pll3 (video PLL). It works most of the time, but not always. Consider monitor with resolution 1920x1200, which has pixel clock rate of 154 MHz. Current code would determine that pll3 rate has to be set to 154 MHz. However, minimum supported rate is 192 MHz. In this case video output just won't work. The reason why the driver is written in the way it is, is that at the time HDMI PHY and clock configuration wasn't fully understood. But now we have needed knowledge, so the issue can be fixed. With this fix, clock configuration routine uses full range (1-16) for clock divider instead of limited one (1, 2, 4, 11). It also considers minimum and maximum allowed rate for pll3.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-079-19/+9
| | | | | | | | | | | | | | | | | | | | 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>
