wlcore: remove wl12xx_platform_data
Now that we have wlcore device-tree bindings in place (for both wl12xx and wl18xx), remove the legacy wl12xx_platform_data struct, and move its members into the platform device data (that is passed to wlcore) Davinci 850 is the only platform that still set the platform data in the legacy way (and doesn't have DT bindings), so remove the relevant code/Kconfig option from the board file (as suggested by Sekhar Nori) Since no one currently uses wlcore_spi, simply remove its platform data support (DT bindings will have to be added if someone actually needs it) Signed-off-by: Luciano Coelho <luca@coelho.fi> Signed-off-by: Eliad Peller <eliad@wizery.com> Tested-by: Nikita Kiryanov <nikita@compulab.co.il> Acked-by: Kalle Valo <kvalo@codeaurora.org> Acked-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

The wl1271 daughter card for AM18x EVMs is a combo wireless

connectivity add-on card, based on the LS Research TiWi module with

Texas Instruments' wl1271 solution.

Say Y if you want to use a wl1271 expansion card connected to the

AM18x EVM.
