2019-06-14gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEMSteve Longerbeam1-1/+1
The saturation bit was being set at bit 9 in the second 32-bit word of the TPMEM CSC. This isn't correct, the saturation bit is bit 42, which is bit 10 of the second word.

2018-11-05gpu: ipu-v3: ipu-ic: allow to manually set resize coefficientsPhilipp Zabel1-19/+33
For tiled scaling, we want to compute the scaling coefficients externally in such a way that the interpolation overshoots tile boundaries and samples up to the first pixel of the next tile. Prepare to override the resizing coefficients from the image conversion code.

2017-12-19gpu: ipu-v3: allow to build with COMPILE_TESTPhilipp Zabel1-0/+1
Add missing include <linux/sizes.h> in ipu-cpmem and ipu-ic, select BITREVERSE for ipu-cpmem and GENERIC_ALLOCATOR for ipu-pre, and allow to build if COMPILE_TEST is enabled. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-09-19gpu: ipu-v3: Add ipu_rot_mode_is_irt()Steve Longerbeam1-1/+1
Add a macro that returns boolean true if the given ipu_rotate_mode requires the use of the Image Rotator. Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-08-08gpu: ipu-v3: Fix IRT usageSteve Longerbeam1-9/+31
There can be multiple IC tasks using the IRT, so the IRT needs a separate use counter. Create a private ipu_irt_enable() to enable the IRT module when any IC task requires rotation, and ipu_irt_disable() when a task no longer needs the IRT.
