Jan Kiszka 83b944174a arm64: dts: hikey: Give wifi some time after power-on ... Somewhere along recent changes to power control of the wl1835, power-on became very unreliable on the hikey, failing like this: wl1271_sdio: probe of mmc2:0001:1 failed with error -16 wl1271_sdio: probe of mmc2:0001:2 failed with error -16 After playing with some dt parameters and comparing to other users of this chip, it turned out we need some power-on delay to make things stable again. In contrast to those other users which define 200 ms, the hikey would already be happy with 1 ms. Still, we use the safer 10 ms, like on the Ultra96.
