drm/tinydrm: Make fb_dirty into a lower level hook

2018-03-28T16:19:32+00:00

mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.

Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.

v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

drm/tinydrm/mi0283qt: Let the display pipe handle power

2018-01-15T14:16:06+00:00

It's better to leave power handling and controller init to the
modesetting machinery using the simple pipe .enable and .disable
callbacks. Remove unused mipi_dbi_pipe_enable().

drm/tinydrm: export mipi_dbi_buf_copy and mipi_dbi_spi_cmd_max_speed

2017-12-01T13:07:16+00:00

This exports the mipi_dbi_buf_copy() and mipi_dbi_spi_cmd_max_speed()
functions so that they can be shared with other drivers.

drm/tinydrm: remove call to mipi_dbi_init() from mipi_dbi_spi_init()

2017-08-04T13:12:25+00:00

This removes the call to mipi_dbi_init() from mipi_dbi_spi_init() so that
drivers can have a driver-specific implementation if needed.
