dt-bindings: phy: bindings document for common Broadcom SATA3 PHY driver
This patch: 1. Renames DT bindings document of Broadcom STB SATA3 PHY driver to common Broadcom SATA3 PHY driver bindings document 2. Adds bindings info for NS2 SATA3 PHY Signed-off-by: Anup Patel <anup.patel@broadcom.com> Acked-by: Rob Herring <robh@kernel.org> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
