gpu: ipu-v3: make const arrays int_reg static, shrinks object size

2018-02-16T13:47:43Z

Don't populate the const read-only arrays int_reg on the stack but instead make them static. Makes the object code smaller by over 80 bytes: Before: text data bss dec hex filename 28024 8936 192 37152 9120 drivers/gpu/ipu-v3/ipu-common.o After: text data bss dec hex filename 27794 9080 192 37066 90ca drivers/gpu/ipu-v3/ipu-common.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King Signed-off-by: Philipp Zabel

gpu: ipu-v3: Allow channel burst locking on i.MX6 only

2017-10-11T08:45:06Z

The IDMAC_LOCK_EN registers on i.MX51 have a different layout, and on i.MX53 enabling the lock feature causes bursts to get lost. Restrict enabling the burst lock feature to i.MX6.

drm: Convert to using %pOF instead of full_name

2017-07-26T11:45:06Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

gpu: ipu-v3: remove interrupt busy waiting routine

2017-06-08T06:57:19Z

This is not used anymore since commit eb8c88808c83 ("drm/imx: add deferred plane disabling"), remove it. Signed-off-by: Philipp Zabel

gpu: ipu-v3: allocate ipuv3_channels as needed

2017-06-08T06:57:19Z

Most of the 64 IPUv3 DMA channels are never used, some of them (channels 16, 30, 32, 34-39, and 53-63) are even marked as reserved. Allocate the channel control structure only when a channel is actually requested, replace the fixed size array with a list, and remove the unused enabled and busy fields from the ipuv3_channel structure.

gpu: ipu-v3: Fix CSI selection for VDIC

2017-06-06T08:21:34Z

The description of the CSI_SEL bit in the i.MX6 reference manual is incorrect. It states "This bit defines which CSI is the input to the IC. This bit is effective only if IC_INPUT is bit cleared". From experiment it was found this is in fact not correct. The CSI_SEL bit selects which CSI is input to _both_ the VDIC _and_ the IC. If the IC_INPUT bit is set so that the IC is receiving from the VDIC, the IC ignores the CSI_SEL bit, but CSI_SEL still selects which CSI the VDIC receives from in that case.

gpu: ipu-v3: don't depend on DRM being enabled

2017-04-04T08:58:56Z

The PRE/PRG drivers, which need the DRM infrastructure, are only used from the output path, so we skip building them into the ipu-v3 driver if CONFIG_DRM is not enabled. Signed-off-by: Lucas Stach Signed-off-by: Philipp Zabel

gpu: ipu-v3: hook up PRG unit
