2014-09-02gpu: ipu-cpmem: Add ipu_cpmem_dump()Steve Longerbeam2-0/+64
Adds ipu_cpmem_dump() which dumps a channel's cpmem to debug. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add more planar formats supportSteve Longerbeam2-18/+120
Adds support for the following planar and partial-planar formats: YUV422 NV12 NV16 Signed-off-by: Dmitry Eremin-Solenikov <[email protected]> Signed-off-by: Mohsin Kazmi <[email protected]> Signed-off-by: Steve Longerbeam <[email protected]> Unified base offset and Y plane offset into a single variable, moved all ipu_cpmem_set_buffer calls to a single location. Removed NV21 and NV61 for now. The IDMAC doesn't understand U/V order for chroma interleaved formats, so we'd need to work around this by implenting U/V switching via the CSC unit. Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-cpmem: Add second buffer support to ipu_cpmem_set_image()Steve Longerbeam2-17/+18

2014-09-02gpu: ipu-cpmem: Add ipu_cpmem_set_block_mode()Steve Longerbeam2-0/+7
Adds ipu_cpmem_set_block_mode(). Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add ipu_idmac_lock_enable()Steve Longerbeam2-0/+70
Adds ipu_idmac_lock_enable(), which enables or disables channel burst locking. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add ipu_idmac_enable_watermark()Steve Longerbeam2-0/+26
Adds the function ipu_idmac_enable_watermark(), which enables or disables watermarking in the IDMAC channel. Enabling watermarking can increase a channel's AXI bus arbitration priority. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add ipu_stride_to_bytes()Steve Longerbeam2-0/+31
Adds ipu_stride_to_bytes(), which converts a pixel stride to bytes, suitable for passing to cpmem. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add __ipu_idmac_reset_current_buffer()Steve Longerbeam1-0/+23
Adds __ipu_idmac_reset_current_buffer() that resets a channel's internal current buffer pointer so that transfers start from buffer 0 on the next channel enable. This operation is required for channel linking to work correctly, for instance video capture pipelines that carry out image rotations will fail after the first streaming unless this function is called for each channel before re-enabling the channels. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add ipu_idmac_clear_buffer()Steve Longerbeam2-0/+29
Add the reverse of ipu_idmac_select_buffer(), that is, clear a buffer ready status in a channel. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Add ipu_idmac_buffer_is_ready()Steve Longerbeam3-1/+27
Add ipu_idmac_buffer_is_ready(), returns true if the given buffer in the given channel is set ready (owned by IPU), or false if not ready (owned by CPU core). Support has been added for third buffer, there is no support yet for triple-buffering in idmac channels, but this function checks buffer-ready for third buffer in case this support is added later. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-09-02gpu: ipu-v3: Move IDMAC channel names to imx-ipu-v3.hSteve Longerbeam2-25/+30
Move the IDMAC channel names to imx-ipu-v3.h, to make the names available outside IPU. Add a couple new channels in the process (async display BG/FG, channels 24 and 29). Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>

2014-08-18staging: imx-drm: Convert to new ipu_cpmem APISteve Longerbeam1-10/+6
The ipu_cpmem_*() calls now take a channel pointer instead of a pointer into cpmem for that channel. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>
2014-08-18gpu: ipu-v3: Add ipu-cpmem unitSteve Longerbeam5-601/+658
Move channel parameter memory setup functions and macros into a new submodule ipu-cpmem. In the process, cleanup arguments to the functions to take a channel pointer instead of a pointer into cpmem for that channel. That allows the structure of the parameter memory to be private to ipu-cpmem.c. Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>

2014-08-16toshiba_acpi: Add extra check to backlight codeAzael Avalos1-4/+17
Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support. This patch changes the set_lcd_brightness function, checking the returned values for values greater than zero to avoid registering a broken backlight interface.
