Allow Headphone and Microphone jack detect gpios to be specified in device tree. This will allow a few systems including rk3288_max98090 to use simple-card instead of having their own board file.
Applied, thanks.
Unfortunately there's no equivalent code for platform data, and the uninitialized default of 0 for gpio_hp_det and gpio_mic_det doesn't play well with asm-generic's gpio_is_valid():
static inline bool gpio_is_valid(int number) { return number >= 0 && number < ARCH_NR_GPIOS; }
Hence on r8a7740/armadillo-legacy, which uses platform devices instead of DT:
sh-mobile-hdmi sh-mobile-hdmi: SH Mobile HDMI Audio Codec sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Mic Jack
After that the kernel log is spammed ca. 7 times per second with:
sh-mobile-hdmi sh-mobile-hdmi: ASoC: DAPM unknown pin Headphones
Reverting commit 3fe240326cc395c66 ("ASoC: simple-card: Add mic and hp detect gpios.") fixes this.
