* video: mark EFI_GOP driver x86-only for nowAhmad Fatoum2024-03-051-0/+1
| | | | | | | | | The driver currently crashes when running barebox on ARM64 Virt under Tianocore. Until that's resolved, mark it x86-only.

* efi: payload: rename CONFIG_EFI_BOOTUP to CONFIG_EFI_PAYLOADAhmad Fatoum2024-03-051-1/+1
| | | | | | | | | | The symbol is internal, so we don't break anything by renaming it. CONFIG_EFI_PAYLOAD is clearer in intent, as BOOTUP doesn't clearly indificate whether barebox would act as EFI payload or as EFI loader.

However, when a monitor is connected, but some other error occurs, barebox is silent. Add a debug message with an error code for this.

* gpio: have gpiod_ functions return and accept pointersAhmad Fatoum2023-06-233-20/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | The gpiod_ (GPIO descriptor) API used with Linux differs from barebox' normal GPIO API: - gpiod handles are opaque pointers and not an integer, which users have an expectation of stability for - gpiod API uses logic levels by default with separate raw API for physical level instead of physical level by default and separate API taking active level into account. The barebox gpiod_ API mimics the latter point, but still uses integers requiring ugly and arguably error prone conversions when porting kernel code. Let's improve upon that by just encoding the integer into a pointer variable for API compatibility. Later commits will switch barebox GPIO support to use actual GPIO descriptors without consulting the numeric indices, but we do this temporary switch here, so we can split up provider and consumer changes.

* | treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-1313-0/+13
|/ | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.

* video: bochs: fix IOMEM usageDenis Orlov2023-05-123-4/+4
| | | | | | | | | | | | | | | | | For the PCI version of the driver, we end up calling IOMEM() twice on both the fb_map and mmio pointers. This happens because we first use pci_iomap() on PCI resources in the bochs_pci_probe() and then explicitly call IOMEM() in the bochs_hw_probe(). However, judging from the parameters of the latter function having __iomem attributes, we should not be remapping them. So, remove those IOMEM calls and instead do explicit remapping in bochs_isa_detect(), which was missing it. Also fix bochs_hw_probe() declaration missing one __iomem.

As barebox display mode handling only supports selecting predefined modes and has no accommodation yet for arbitrary resolution support like on QEMU, for now we just provide a fixed 640x480@XRGB8888 mode.

| | | | | | | | | | | | | | | | | | | | | | To add a compilation check for the omap-fb driver, move the omap-fb.h header to a global location. The "omap_add_display" function is used only for legacy boards, so we will move it to a common place for such calls (omap_devices.c).

* video: add driver for STM32 LCD-TFT Display ControllerAhmad Fatoum2022-02-074-0/+475
| | | | | | | | | | | | | This driver has been tested on a STM32F429 connected to an Ilitek 9341 Display for which support is added in a follow-up commit. The same driver can be used (but wasn't tested) for the STM32MP1 as well. The official ST evaluation kits all use MIPI-DSI for which we still lack support. The LXA MC-1 has a parallel display connected to the LTDC, but I didn't have one readily available to test.

* video: ssd1307fb: add spi supportMichael Tretter2022-01-032-7/+57
| | | | | | | | | | | | | The Solomon display drivers also support SPI in addition to the I2C. Add SPI support to the driver that already supports I2C by implementing the bus write function for SPI and registering an SPI driver. While the driver needs I2C or SPI, either subsystem is optional as long as one is enabled.
