The commit b1b8f45b3130 ("ARM: dts: bcm2837: Add missing GPIOs of Expander") introduced a wifi power sequence. Unfortunately the polarity of the reset GPIOs were wrong and broke the wifi support on Raspberry Pi 3 B and later in 3 B+. This wasn't discovered before since the power sequence takes only effect in case the relevant MMC driver is compiled as a module.
