This pull request contains drivers related changes for Broadcom SoCs:
- Florian moves drivers/soc/brcmstb to drivers/soc/bcm/brcmstb to be consistent with how other SoCs are doing it - Chris provides a reset driver which is common to the BCM21664 and BCM23550 SoCs - Ben fixes a warning by providing the appropriate include file -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXY1WaAAoJEIfQlpxEBwcErVMQAK9dNwq7Zul5NPc+QXe/0vUy hLzjF2qm8CEqxU+YF3B1OSI4DHFEdJi3kgDq0RwaVoNC11nFdD5CQIKiB2a0O4jL HYlRSir2BoeuSdt/IUry8tdUJOy1LhK/OM0yu/E4OJq/yHgimM/D2+kh6ToSS23s X2rocyat7CUAqtiEXroYmWgu+UbUI9Dst+WtXJ4bL6iJe5asZPeTFdxNuMmO0RBF XcGY7nmOD420jhYJvZkZUibo/tz/i57Ar2i0SFpTgQGQ1DHbmyhEFCbOm6QuZ3J0 l5deISy0buXfTTc15n9zhoqZxtGiM3ExqEhrTdvaSjBkZrZUUhjKo+ED5yGJ7Yqy 2cRP1dua4ixEbOJoAU+IuoqDj42zOxpOLhwNi7e8ROTqXfxHxAVizPJ6dKZKP1vz 6KqqJtEoD+U9mrylAQ55+D68e1kNy7r8TN4qJBhrNSO3G2bWogYzUKHFMdSPyNFY /g0qhAwBrvPHw1ieezS74uMCIF525QfylpcX4MP0s48fAN32SQPdFb5mZuxzqvVH V0Z/VShkndLkoslChEZ5intuvMDUMyP1tdwvthuvoJQOVh59Fede+7TG+wsxzOGP FbWGhtWzxVzKLOvwBZhLMv5VwPH7rFSSTuc3tT2xMtpoMy/lhRabH/nqQKdm9CET uzRJ8hDFy3oWx3L95nA/ =gNzd -----END PGP SIGNATURE----- Merge tag 'arm-soc/for-4.8/drivers' of http://github.com/Broadcom/stblinux into next/drivers This pull request contains drivers related changes for Broadcom SoCs: - Florian moves drivers/soc/brcmstb to drivers/soc/bcm/brcmstb to be consistent with how other SoCs are doing it - Chris provides a reset driver which is common to the BCM21664 and BCM23550 SoCs - Ben fixes a warning by providing the appropriate include file * tag 'arm-soc/for-4.8/drivers' of http://github.com/Broadcom/stblinux: soc: brcmstb: fix warning from missing include power: Introduce Broadcom kona reset driver soc: Move brcmstb to bcm/brcmstb Signed-off-by: Olof Johansson <olof@lixom.net>
