Ok, I hope I got it this time: - The hs_jack_gpio/"earphone-det" is declared as GPIO_ACTIVE_LOW, with the ".invert" dropped in the snd_soc_jack_gpio definition to match - "spk-sd" is declared as GPIO_ACTIVE_LOW, so both this and "hp-driver" are enabled by setting the gpio to active, rather than the two being opposites - snd_soc_jack_pin flips the 'invert' flag from speaker to headphone, since the "earphone-det" is now reversed - hx4700_spk_power() flips polarity when setting the output to match the GPIO_ACTIVE_LOW setting, but hx4700_hp_power() does not change. Arnd commit 20a9b05eff0488b78aa02c07f58654daa294069a Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Wed Sep 11 14:27:13 2019 +0200 ARM: pxa: hx4700: use gpio descriptors for audio The audio driver should not use a hardwired gpio number from the header. Change it to use a lookup table.
