2019-07-25drm/tinydrm: Move mipi-dbiNoralf Trønnes
This moves mipi-dbi to be a core helper with the name drm_mipi_dbi. Fixup include's in drivers. Move the docs entry and delete tinydrm.rst. Delete the last tinydrm todo entry. v2: Make DRM_MIPI_DBI tristate to enable it being built as a module.

2019-07-25drm/tinydrm/Kconfig: drivers: Select BACKLIGHT_CLASS_DEVICENoralf Trønnes
The mipi_dbi helper is missing a dependency on DRM_KMS_HELPER and putting that in revealed this problem: drivers/video/fbdev/Kconfig:12:error: recursive dependency detected! drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:75: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:69: symbol DRM_KMS_HELPER is selected by TINYDRM_MIPI_DBI drivers/gpu/drm/tinydrm/Kconfig:11: symbol TINYDRM_MIPI_DBI is selected by TINYDRM_HX8357D drivers/gpu/drm/tinydrm/Kconfig:15: symbol TINYDRM_HX8357D depends on BACKLIGHT_CLASS_DEVICE drivers/video/backlight/Kconfig:144: symbol BACKLIGHT_CLASS_DEVICE is selected by FB_BACKLIGHT drivers/video/fbdev/Kconfig:187: symbol FB_BACKLIGHT depends on FB A symbol that selects DRM_KMS_HELPER can not depend on BACKLIGHT_CLASS_DEVICE. The reason for this is that DRM_KMS_FB_HELPER selects FB instead of depending on it. The tinydrm drivers have somehow gotten away with depending on BACKLIGHT_CLASS_DEVICE because DRM_TINYDRM selects DRM_KMS_HELPER and the drivers depend on that symbol. An audit shows that all DRM drivers that select DRM_KMS_HELPER and use BACKLIGHT_CLASS_DEVICE, selects it: DRM_TILCDC, DRM_GMA500, DRM_SHMOBILE, DRM_NOUVEAU, DRM_FSL_DCU, DRM_I915, DRM_RADEON, DRM_AMDGPU, DRM_PARADE_PS8622 Documentation/kbuild/kconfig-language.txt has a note regarding select: 1. 'select should be used with care since it doesn't visit dependencies.' This is not a problem since BACKLIGHT_CLASS_DEVICE doesn't have any dependencies. 2. 'In general use select only for non-visible symbols' BACKLIGHT_CLASS_DEVICE is user visible. The real solution to this would be to have DRM_KMS_FB_HELPER depend on the user visible symbol FB. That is a can of worms I'm not willing to tackle. I fear that such a change will result in me handling difficult fallouts for the next weeks. So I'm following DRM suite here.

2019-07-25drm/tinydrm: Split struct mipi_dbi in twoNoralf Trønnes
Split struct mipi_dbi into an interface part and a display pipeline part. The interface part can be used by drivers that need to initialize the controller, but that won't upload the framebuffer over this interface. MIPI DBI supports 3 interface types: - A. Motorola 6800 type parallel bus - B. Intel 8080 type parallel bus - C. SPI type with 3 options: I've embedded the SPI type specifics in the mipi_dbi struct to avoid adding unnecessary complexity. If more interface types will be supported in the future, the type specifics might have to be split out. Rename functions to match the new struct mipi_dbi_dev: - drm_to_mipi_dbi() -> drm_to_mipi_dbi_dev(). - mipi_dbi_init*() -> mipi_dbi_dev_init*().

2019-07-23video: ssd1307fb: Add devicetree configuration of display setupMarko Kohtala
Various displays have differences that only mean initializing the display driver IC with different fixed register values. Defining these in devicetree offers easier way to adapt the driver to new displays than requiring a patch to the kernel. This adds devicetree properties needed to make the initialization match the example setup as offered by Densitron for their 128x36 display. It also makes some old one bit parameter handling a little cleaner.

Some displays have dimensions that are not multiple of eight, for example height of 36, but the driver divided the dimensions by 8. Defining display to the next multiple of 8 is not good as then the display registers get configured to dimensions that do not match. This contradicts intructions by some display manufacturers. Use DIV_ROUND_UP to multiple of 8 when needed so correct values can be used. The ssd1307fb_update_display bit reordering receives a simplification in the process.

Low memory boards (64MB) can run into a problem allocating such a "large" contiguous buffer on every transfer after a long up time. This leaves a very specific use case, so we'll keep the function here. mipi-dbi will first go through a refactoring though, before this will be done.

2019-07-23drm/tinydrm: Remove tinydrm_spi_max_transfer_size()Noralf Trønnes
spi-bcm2835 can handle >64kB buffers now so there is no need to check ->max_dma_len. The tinydrm_spi_max_transfer_size() max_len argument is not used by any callers, so not needed. Then we have the spi_max module parameter. It was added because staging/fbtft has support for it and there was a report that someone used it to set a small buffer size to avoid popping on a USB soundcard on a Raspberry Pi. In hindsight it shouldn't have been added, I should have waited for it to become a problem first. I don't know it anyone is actually using it, but since tinydrm_spi_transfer() is being moved to mipi-dbi, I'm taking the opportunity to remove it. I'll add it back to mipi-dbi if someone complains. With that out of the way, spi_max_transfer_size() can be used instead. The chosen 16kB buffer size for Type C Option 1 (9-bit) interface is somewhat arbitrary, but a bigger buffer will have a miniscule impact on transfer speed, so it's probably fine.

2019-07-21drm: Add Grain Media GM12U320 driver v2Hans de Goede
Add a modesetting driver for Grain Media GM12U320 based devices (primarily Acer C120 projector, but there may be compatible devices). This is based on the fb driver from Viacheslav Nurmekhamitov: https://github.com/slavrn/gm12u320 This driver uses drm_simple_display_pipe to deal with all the atomic stuff, gem_shmem_helper functions for buffer management and drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver itself with only the actual code for talking to the gm12u320 chip, leading to a nice simple and clean driver.

2019-07-20drm/sun4i: sun8i-csc: Add support for color encoding and rangeJernej Skrabec
Conversion from YUV to RGB depends on range (limited or full) and encoding (BT.601 or BT.709). Current code doesn't consider this and always uses BT.601 encoding and limited range. Fix this by introducing new CSC matrices, which are selected based on range and encoding parameters.
