Add support for R-Car E3 R8A77965 to R-Car CSI-2 driver. Based on the experimental patch from Magnus Damm. Signed-off-by: Jacopo Mondi <jacopo+renesas@xxxxxxxxxx> --- The upported BSP patch https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-bsp.git/commit/?id=59d3ad972acdba8b75a14113efbbca7f9c709345 includes a few more things to handle E3: - E3 supports a single VC: do not write to VCDT2 register I feel there is not harm in doing that, but in case I can add that check - phtw_testin handling: it seems to me phtw_testing is handled for all SoCs in the mainline csi-2 driver, and it is not necessary to add it specifically for E3. Niklas, could you maybe check?
