ARM: dts: at91: sama5d27_wlsom1: add SAMA5D27 wlsom1 and wlsom1-ek
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@microchip.com]: initial implementation Signed-off-by: Nicolas Ferre <nicolas.ferre@microchip.com> [eugen.hristev@microchip.com]: ported to new kernel version, [eugen.hristev@microchip.com]: addition of peripherals (adc, pmic, qspi, uart) Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> Link: https://lore.kernel.org/r/1573543139-8533-4-git-send-email-eugen.hristev@microchip.com Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
