+Subject: [PATCH] soc: bcm: brcmstb: add stubs for getting platform IDs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
