literally just attach it like that, iconic, no notes 🫶

🦋 DESCRIPTION 🦋

okay so here's the tea: the tea5767 driver provides support for the Philips/NXP TEA5767 FM stereo radio. yes. an actual FM stereo radio. inside your kernel. we love to see it ✨

the tea5767 can tune in the range 87.5 - 108.0 MHz, perform hardware signal search, and supports mono/stereo toggling. versatile queen 👑

the flags control the FM Band, XTAL, and PLL values, and here's the breakdown, don't skip it:

  • 0x01 — Sets the FM Band to Japan. 🇯🇵
  • 0x02 — Sets the PLL bit.
  • 0x04 — Sets the XTAL bit.
  • 0x08 — Force enables hardware search support. 💪

⭐ SEE ALSO ⭐

also waving hi to this reference doc: TEA5767, Low-power FM stereo radio, Rev. 05, 26 January 2007. it's cited, it's real, go read it 📚

🙈 CAVEATS 🙈

okay this is the part where I hold your hand because it matters 😭

Many popular TEA5767 evaluation boards feature low quality 32.768kHz crystals. low quality. the inaccuracy of these crystals may often lead to malfunction of the hardware search function. yeah. it can just kinda... not work. 💀

Therefore, the tea5767 driver tries to detect the crystal quality during attachment. If the crystal of insufficient accuracy was detected, the hardware search function is disabled. it's protecting you bestie 🫶

but if you really want it back, it can be forcefully re-enabled by setting the 0x08 flag. your call, your radio, your consequences 💅

so yeah, that's the whole page! this one's from Debian, dated July 6, 2018 — mwah, love that for us, drink some water and go tune something 🌈💜
