gpu: ipu-v3: csi: pass back mbus_code_to_bus_cfg error codes

2018-09-26T06:39:38+00:00

[ Upstream commit d36d0e6309dd8137cf438cbb680e72eb63c81425 ] mbus_code_to_bus_cfg() can fail on unknown mbus codes; pass back the error to the caller.

gpu: ipu-v3: default to id 0 on missing OF alias

2018-09-19T20:41:26+00:00

[ Upstream commit 2d87e6c1b99c402360fdfe19ce4f579ab2f96adf ] This is better than storing -ENODEV in the id number. This fixes SoCs with only one IPU that don't specify an IPU alias in the device tree. Signed-off-by: Philipp Zabel Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

gpu: ipu-csi: Check for field type alternate

2018-07-16T14:56:35+00:00

When the CSI is receiving from a bt.656 bus, include a check for field type 'alternate' when determining whether to set CSI clock mode to CCIR656_INTERLACED or CCIR656_PROGRESSIVE. Signed-off-by: Steve Longerbeam Signed-off-by: Philipp Zabel

gpu: ipu-v3: prg: avoid possible array underflow

2018-03-15T16:52:08+00:00

gcc-8 reports that we access an array with a negative index in an error case: drivers/gpu/ipu-v3/ipu-prg.c: In function 'ipu_prg_channel_disable': drivers/gpu/ipu-v3/ipu-prg.c:252:43: error: array subscript -22 is below array bounds of 'struct ipu_prg_channel[3]' [-Werror=array-bounds] This moves the range check in front of the first time that variable gets used.

gpu: ipu-csi: add 10/12-bit grayscale support to mbus_code_to_bus_cfg

2018-02-19T14:13:05+00:00

The 10/12-bit config used for bayer formats is used for grayscale as well. Signed-off-by: Jan Luebbe Signed-off-by: Philipp Zabel

gpu: ipu-cpmem: add 16-bit grayscale support to ipu_cpmem_set_image

2018-02-19T14:13:00+00:00

Add the missing offset calculation for 16-bit grayscale images. Since the IPU only supports capturing greyscale in raw passthrough mode, it is the same as 16-bit bayer formats. Signed-off-by: Philipp Zabel

gpu: ipu-v3: prg: fix device node leak in ipu_prg_lookup_by_phandle

2018-02-19T14:12:59+00:00

Before returning, call of_node_put() for the device node returned by of_parse_phandle(). Fixes: ea9c260514c1 ("gpu: ipu-v3: add driver for Prefetch Resolve Gasket") Signed-off-by: Tobias Jordan Signed-off-by: Philipp Zabel

gpu: ipu-v3: pre: fix device node leak in ipu_pre_lookup_by_phandle

2018-02-19T14:12:59+00:00

gpu: ipu-cpmem: add 8-bit grayscale support to ipu_cpmem_set_image

2018-02-16T13:48:11+00:00

Add the missing offset calculation for grayscale images. Since the IPU only supports capturing greyscale in raw passthrough mode, it is the same as 8-bit bayer formats. Signed-off-by: Philipp Zabel

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

2018-02-16T13:47:43+00:00

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
