2019-07-31drm/tinydrm: Rename folder to tinyNoralf Trønnes1-268/+0
The drm in tinydrm is superfluous so rename to tiny.

2019-07-25drm/tinydrm: Move mipi-dbiNoralf Trønnes1-1/+1
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: Split struct mipi_dbi in twoNoralf Trønnes1-5/+5
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*().

2019-07-25drm/tinydrm: Rename remaining variable mipi -> dbidevNoralf Trønnes1-15/+15
struct mipi_dbi is going to be split 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. tinydrm uses the variable name 'mipi' but this is not a good name since MIPI refers to a lot of standards. This patch changes the variable name to 'dbidev' where it refers to the pipeline part of struct mipi_dbi.

2019-07-23drm/tinydrm: Move tinydrm_display_pipe_init() to mipi-dbiNoralf Trønnes1-1/+0
tinydrm_display_pipe_init() has only one user now, so move it to mipi-dbi. Changes: - Remove drm_connector_helper_funcs.detect, it's always connected. - Store the connector and mode in mipi_dbi instead of it's own struct. Otherwise remove some leftover tinydrm-helpers.h inclusions.

2019-04-11drm/tinydrm: Fix fbdev pixel formatNoralf Trønnes1-1/+1
Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888 which is an emulated format for the RGB565 drivers. Revert to to using the fallback which is dev->mode_config.preferred_depth for the drivers that set it or 32bpp for those that don't (repaper, st7586).

2019-03-04drm/tinydrm: Use drm_dev_enter/exit()Noralf Trønnes1-2/+7
This protects device resources from use after device removal. There are 3 ways for driver-device unbinding to happen: - The driver module is unloaded causing the driver to be unregistered. This can't happen as long as there are open file handles because a reference is taken on the module. - The device is removed (Device Tree overlay unloading). This can happen at any time. - The driver sysfs unbind file can be used to unbind the driver from the device. This can happen any time. v2: Since drm_atomic_helper_shutdown() has to be called after drm_dev_unplug() we don't want do block ->disable after unplug.

drmP.h was the only header file in the past and a lot of files rely on that drmP.h defines everything. The goal is to one day to delete drmP.h and as a step towards this it will no longer be included in the headers files in include/drm/ To prepare tinydrm/ for this add dependencies that othwewise was pulled in by drmP.h from drm_gem_cma_helper.h To avoid that tinydrm.h became "include everything", push include files to the individual drivers.
