media: driver/nxp/imx-jpeg: fix a unexpected return value problem

2022-08-17T13:14:35Z

[ Upstream commit 5b304046a81eda221b5d06a9c62f7b5e45530fa5 ] In function mxc_jpeg_probe(), when devm_clk_get() fail, the return value will be unexpected, and it should be the devm_clk_get's error code.

media: imx-jpeg: Disable slot interrupt when frame done

2022-08-17T13:14:34Z

[ Upstream commit 22a2bc88c139dc9757bdb1d0a3665ac27edc79a5 ] The interrupt STMBUF_HALF may be triggered after frame done. It may led to system hang if driver try to access the register after power off. Disable the slot interrupt when frame done.

[ Upstream commit 4911c5acf9351c4caf692895c7cf6a4fa46c26b0 ] v4l2 m2m has supplied some helper function to handle drain, so the driver can use the helper function directly.

media: imx-jpeg: Align upwards buffer size

2022-08-17T13:14:32Z

[ Upstream commit 9e7aa76cdb02923ee23a0ddd48f38bdc3512f92b ] The hardware can support any image size WxH, with arbitrary W (image width) and H (image height) dimensions. Align upwards buffer size for both encoder and decoder. and leave the picture resolution unchanged. For decoder, the risk of memory out of bounds can be avoided. For both encoder and decoder, the driver will lift the limitation of resolution alignment. For example, the decoder can support jpeg whose resolution is 227x149 the encoder can support nv12 1080P, won't change it to 1920x1072.

2022-08-17T13:14:32Z

[ Upstream commit 6285cdea19daf764bf00f662a59fc83ef67345cf ] There is a hardware bug that it will load the first 128 bytes of configuration data twice, it will led to some configure error. so shift the configuration data 128 bytes, and make the first 128 bytes all zero, then hardware will load the 128 zero twice, and ignore them as garbage. then the configuration data can be loaded correctly Fixes: 2db16c6ed72ce ("media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder") Signed-off-by: Ming Qian Reviewed-by: Mirela Rabulea Reviewed-by: Tommaso Merciai Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Sasha Levin

media: imx-jpeg: Support dynamic resolution change

2022-05-13T09:02:19Z

To support dynamic resolution change, driver should meet the following conditions: 1. the previous pictures are all decoded before source change event. 2. prevent decoding new resolution pictures with incorrect capture buffer, until user handle source change event and setup capture. 3. report correct fmt and resolution during source change.
