2019-07-25drm/tinydrm: Move mipi-dbiNoralf Trønnes1-18/+0
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.

2019-07-23drm/tinydrm: Move tinydrm_display_pipe_init() to mipi-dbiNoralf Trønnes1-9/+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.

2019-07-23drm/tinydrm: Move tinydrm_spi_transfer()Noralf Trønnes1-3/+0
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. Remove SPI todo entry now that we're done with the tinydrm.ko SPI code. v2: Drop moving the mipi_dbi_spi_init() declaration (Sam) Cc: David Lechner <david@lechnology.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-8-noralf@tronnes.org
