From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>
This is the addition of a new Evaluation Kit the SAMA5D27-WLSOM1-EK.
It's based on the Microchip WireLess SoM which contains the
SAMA5D27 LPDDR2 2Gbits SiP.
[nicolas.ferre@xxxxxxxxxxxxx]: initial implementation
Signed-off-by: Nicolas Ferre <nicolas.ferre@xxxxxxxxxxxxx>
[eugen.hristev@xxxxxxxxxxxxx]: ported to new kernel version,
[eugen.hristev@xxxxxxxxxxxxx]: addition of peripherals (adc, pmic, qspi, uart)
Signed-off-by: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>
