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

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.
