Your post makes no sense.
The SAMA5D2 and SAMA5D4 are not "processors"; they are families of SoCs which have ARM Cortex-A5 processors.
Neither SoC has a HDMI interface, so there is no HDMI driver associated with either SoC.

Hello Blue_z

Thanks for your time and excuse my bad expresion and my poor english

I`ll try to explain me, I need to know if it`s possible to use the LCD 24-bit output of the SiP SAMA5D27C-D1G with the CI Sil9022 to get an HDMI output like the in the case of SoC SAMA5D43? and if exist an HDMI driver for SiI902x component on SAMA5D27C-D1G

Thanks and best regards
Victor

You still have a problem conflating SoCs and boards.
One more time: the SAMA5D43 is a SoC, and does not have a HDMI output (nor does any SAMA5Dx SoC).
BTW both the SAMA5D4-EK and SAMA5D4-XULT boards use the SAMA5D44 SoC; your reference to a "SAMA5D43" is confusing.

But the SiI9022A bridge chip has been used by Atmel on three boards, SAMA5D3x-EK, SAMA5D4-EK, and SAMA5D4-XULT, to provide an HDMI port.
I'm not a circuit/board designer, so I can't answer what is possible with a board using other SoCs or modules.

A Linux driver for the SiI902x has been available in the Linux4SAM kernels since version 3.10-at91, although audio support over HDMI is questionable.
