drm/ast: Support multiple outputs
Systems with AST graphics can have multiple output; typically VGA plus some other port. Record detected output chips in a bitmask and initialize each output on its own. Assume a VGA output by default and use SIL164 and DP501 if available. For ASTDP assume that it can run in parallel with VGA. Tested on AST2100. v3: * define a macro for each BIT(ast_tx_chip) (Patrik) v2: * make VGA/SIL164/DP501 mutually exclusive Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Fixes: a59b026419f3 ("drm/ast: Initialize encoder and connector for VGA in helper function") Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Javier Martinez Canillas <javierm@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20220607092008.22123-2-tzimmermann@suse.de (cherry picked from commit 7f35680ada234ce00828b8ea841ba7ca1e00ff52) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
