From d23d4d4dac0119c7bfba63342a86a68b38c01779 Mon Sep 17 00:00:00 2001 From: Noralf Trønnes Date: Fri, 19 Jul 2019 17:59:12 +0200 Subject: drm/tinydrm: Move tinydrm_spi_transfer() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 Reviewed-by: Sam Ravnborg Acked-by: : David Lechner Signed-off-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-8-noralf@tronnes.org --- Documentation/gpu/tinydrm.rst | 3 --- Documentation/gpu/todo.rst | 3 --- 2 files changed, 6 deletions(-) (limited to 'Documentation/gpu') diff --git a/Documentation/gpu/tinydrm.rst b/Documentation/gpu/tinydrm.rst index 33a41544f659..2c2860fa1510 100644 --- a/Documentation/gpu/tinydrm.rst +++ b/Documentation/gpu/tinydrm.rst @@ -11,9 +11,6 @@ Helpers .. kernel-doc:: include/drm/tinydrm/tinydrm-helpers.h :internal: -.. kernel-doc:: drivers/gpu/drm/tinydrm/core/tinydrm-helpers.c - :export: - .. kernel-doc:: drivers/gpu/drm/tinydrm/core/tinydrm-pipe.c :export: diff --git a/Documentation/gpu/todo.rst b/Documentation/gpu/todo.rst index a38639e96e8b..688b4adbbf62 100644 --- a/Documentation/gpu/todo.rst +++ b/Documentation/gpu/todo.rst @@ -443,9 +443,6 @@ tinydrm Tinydrm is the helper driver for really simple fb drivers.
