Some brcmstb drivers may be shared with other SoC families. E.g. the same USB PHY block is shared by brcmstb and BCM4908. To avoid building brcmstb common code on non-brcmstb platforms we need stubs for: 1. brcmstb_get_family_id() 2. brcmstb_get_product_id() (to avoid "undefined reference to" errors). With this change PHY_BRCM_USB will not have to unconditionally select SOC_BRCMSTB anymore. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
