^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) Introduction
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) ------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Which contains several components that can be categorized in 3 big groups:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) - ISP (Image Signal Processor)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) - SIMCOP (Still Image Coprocessor)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) For more information, please look in [#f1]_ for latest version of:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) "OMAP4430 Multimedia Device Silicon Revision 2.x"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) As of Revision AB, the ISS is described in detail in section 8.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) This driver is supporting **only** the CSI2-A/B interfaces for now.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) It makes use of the Media Controller framework [#f2]_, and inherited most of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/\*),
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) except that it doesn't need an IOMMU now for ISS buffers memory mapping.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) Supports usage of MMAP buffers only (for now).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) Tested platforms
