   4 Subject: [PATCH] soc: bcm: brcmstb: add stubs for getting platform IDs

   9 Some brcmstb drivers may be shared with other SoC families. E.g. the
  10 same USB PHY block is shared by brcmstb and BCM4908.
  11
  12 To avoid building brcmstb common code on non-brcmstb platforms we need
  13 stubs for:
  14 1. brcmstb_get_family_id()
  15 2. brcmstb_get_product_id()
  16 (to avoid "undefined reference to" errors).
  17
  18 With this change PHY_BRCM_USB will not have to unconditionally select
  19 SOC_BRCMSTB anymore.
