From 149ae80b1d50e7db5ac7df1cdf0820017b70e716 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 14 Jan 2021 11:53:18 +0100 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.
