media: arch: sh: ap325rxa: Use new renesas-ceu camera driver
Use the new renesas-ceu camera driver in ap325rxa board file instead of the soc_camera based sh_mobile_ceu_camera driver. Get rid of soc_camera specific components, and register CEU0 with a single video sensor (ov7725). Memory for the CEU video buffers is now reserved with membocks APIs and need to be declared as dma_coherent during machine initialization to remove that architecture specific part from CEU driver. The ap325rxa board file registers another camera (ncm03j) for which I found no driver in mainline kernel version, and that was configured/probed by sending i2c messages (of 'magic blobs) from the board file itself. I removed the sensor registration from this new version as it used soc_camera components that will be later removed. While at there update license to SPDX header and sort headers alphabetically. Compile tested only. Signed-off-by: Jacopo Mondi <jacopo+renesas@jmondi.org> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
