2019-07-24drm/mgag200: Don't unpin the current cursor image's buffer.Thomas Zimmermann1-1/+0
Currently the displayed cursor buffer might be evicted from video memory. Not unpinning the BO fixes this problem. At this point, pixels_current also references the BO and it will be unpinned during the next cursor update.

2019-07-23video: ssd1307fb: Add devicetree configuration of display setupMarko Kohtala1-16/+65
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.

2019-07-23video: ssd1307fb: Handle width and height that are not multiple of 8Marko Kohtala1-13/+17
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.

If it was use on a not cache coherent bus that would be fatal, but as far as I can tell from the naming and the mips platform implementation it always is used in cache coherent systems.

2019-07-23drm/tinydrm: Move tinydrm_spi_transfer()Noralf Trønnes9-87/+57
This is only used by mipi-dbi drivers so move it there. The reason this isn't moved to the SPI subsystem is that it will in a later patch pass a dummy rx buffer for SPI controllers that need this. 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.

Prep work before moving the function to mipi-dbi. tinydrm_spi_transfer() was made to support one class of drivers in drivers/staging/fbtft that has not been converted to DRM yet, so strip away the unused functionality: - Start byte (header) is not used. - No driver relies on the automatic 16-bit byte swapping on little endian machines with SPI controllers only supporting 8 bits per word.

2019-07-23drm/tinydrm: Remove tinydrm_spi_max_transfer_size()Noralf Trønnes3-45/+3
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.

After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit 13aff184ed9f ("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit 26d4707d445d ("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190721140610.GA20842@ravnborg.org

2019-07-21dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring1-82/+61
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

2019-07-21dt-bindings: Ensure child nodes are of type 'object'Rob Herring6-0/+8
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.
