This pull request contains fixes to make the WiFi work again for the ARM64
Hikey board. Together with a couple of DTS updates for the Hikey board we have also extended the mmc pwrseq_simple, to support a new power-off-delay-us DT property, as that was required to enable a graceful power off sequence for the WiFi chip. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJZKCWUAAoJEP4mhCVzWIwpmQ4P/RwUxeM3U29xp2+Zf/Rn20oR BKjPbSoXs+5OmeLrEre5MikjY6hjYmWXBBBIBwORVZbtGpMwDTT5T9aLQ1usu5b4 VIqLvKj6D1a85Ssu0/KKT5ue7VzOeZudQfcdpIE73wB5kzyWPzcEg0yqDQM9eAFx IDkefpwL8YImAoPmBAVlTpiovqstSvKORJRM5TVpREw0+P6qy3vH1hWRpFB6CFfG rrT8Rv+7xGPsIrsaU2SNl+2w8sF2cXXTs2IW7dQciCEM+hUuzYAb20fxwqKhRQsh zFyoF3NzhHJzz48v3NWJFKncWcVFlzv4xfa1bxsUSUbpikRWl7sxWkAVU4QSF7pq 71Vqim7zgE5Nt3hSx85lUWTvSoOkNDPhirAWBhfPv/zd8d6Gn2rET1GfhQhPrd43 Gf8Axz2Mbr4g+x05e7meGyzpv0FScbhvY00tcuyTLQ3inoyyC+3OxnbSRgnGuz22 cJxCQ34LELYKxSQDpdODjGrHywWOwgjlATgzE6OiA0OFFbDR4PhEVMsAFimi+i69 XsTWvoz56NA+NOImpKSnztXdTm/PAjBzCuc6Ii49OS1wEgKVHCA46YeF9I0NWt6E yqTwcKScJcBfFf6etsA9mV+A+jGCBImye6jCuLJAJsWE2qACv1B12DfLdW0LFQl7 6e6OAtw02hEs0HPvMsHP =ECeh -----END PGP SIGNATURE----- Merge tag 'mmc-v4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc Pull MMC fixes from Ulf Hansson: "This contains fixes to make the WiFi work again for the ARM64 Hikey board.
