wireless: mwifiex: initial commit for Marvell mwifiex driver
This driver adds WiFi support for Marvell 802.11n based chipsets with SDIO interface. Currently only SD8787 is supported. More chipsets will be supported later. drivers/net/wireless/mwifiex/ Signed-off-by: Nishant Sarmukadam <nishants@marvell.com> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Kiran Divekar <dkiran@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: Yogesh Ashok Powar <yogeshp@marvell.com> Signed-off-by: Marc Yang <yangyang@marvell.com> Signed-off-by: Ramesh Radhakrishnan <rramesh@marvell.com> Signed-off-by: Frank Huang <frankh@marvell.com> Signed-off-by: John W.
