Add kernel support for SAMA7G5 by back-porting mainline kernel patches. Among SAMA7G5 features could be remembered: - ARM Cortex-A7 - double data rate multi-port dynamic RAM controller supporting DDR2, DDR3, DDR3L, LPDDR2, LPDDR3 up to 533MHz - peripherals for audio, video processing - 1 gigabit + 1 megabit Ethernet controllers - 6 CAN controllers - trust zone support - DVFS for CPU - criptography IPs Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com>

Subject: [PATCH 193/247] media: atmel: atmel-sama5d2-isc: fix YUYV format
|
|
|
|
SAMA5D2 does not have the YCYC field for the RLP (rounding, limiting,
|
|
packaging) module.
|
|
The YCYC field is supposed to work with interleaved YUV formats like YUYV.
|
|
In SAMA5D2, we have to use YYCC field, which is used for both planar
|
|
formats like YUV420 and interleaved formats like YUYV.
|
|
Fix the according rlp callback to replace the generic YCYC field (which
|
|
makes more sense from a logical point of view) with the required YYCC
|
|
field.
|
|
|
|
