ARM: dts: dra72-evm-common: Add wilink8 wlan support
Wilink8 module is a combo wireless connectivity card based on Texas Instrument's wl18xx solution. Add support for the wlan capabilities of this module by muxing the relevant mmc lines, and setting the required device-tree data. Signed-off-by: Eyal Reizer <eyalr@ti.com> Signed-off-by: Hari Nagalla <hnagalla@ti.com> [nsekhar@ti.com: drop WLAN_EN pinmux. It should be done by bootloader. Also, some commit message adjustments] Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
