 Subject: [PATCH] phy: phy-brcm-usb: select SOC_BRCMSTB on brcmstb only
 MIME-Version: 1.0
 Content-Type: text/plain; charset=UTF-8
 Content-Transfer-Encoding: 8bit
 
-BCM4908 doesn't need brcmstb SoC stuff compiled.
+phy-brcm-usb has some conditional init code required on selected brcmstb
+devices. Execution of that code depends on family / product detected by
+brcmstb soc code.
 
+For ARCH_BCM4908 brcmstb soc code always return 0 values as ids. Don't
+bother selecting & compiling that redundant driver.
+
+Depends-on: 149ae80b1d50 ("soc: bcm: brcmstb: add stubs for getting platform IDs")
