* ALSA: cs5535audio: turn off mic bias on OLPCs by defaultAndres Salomon2008-12-101-0/+2
| | | | | | | | Always turn off mic bias; the MIC LED should never come on when the driver is first loaded. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: cs5535audio: rename V_REFOUT control to MIC BiasAndres Salomon2008-12-101-4/+69
| | | | | | | | This drops the AD1888 V_REFOUT control, and replaces it with a MIC Bias Enable control. It also moves the MIC bias enabling into a separate function. Signed-off-by: Andres Salomon <dilinger@debian.org>
* ALSA: cs5535audio: check OLPC's Analog Input status vis GPIOAndres Salomon2008-12-101-7/+2
| | | | | | | | Checking the HPF register is irrelevant; HPF is secondary to the AI mode. Instead, check for Analog Input mode via GPIO. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: cs5535audio: rename OLPC's analog input control && drop AD1888's HPFAndres Salomon2008-12-101-15/+21
| | | | | | | | | Previously, we had two separate controls; there's no need to have AD1888's HPF control, so drop it if we're on an OLPC machine. Also, as per Arjun's request, rename OLPC's Analog Input Switch control to "DC Mode Enable". Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: cs5535audio: create function for setting OLPC's Analog Input modeAndres Salomon2008-12-101-30/+24
| | | | | | | Clean this stuff up a bit.. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: cs5535audio: decouple HPF from V_REFOUT in OLPC codeAndres Salomon2008-12-101-21/+4
| | | | | | | | We shouldn't be touching V_REFOUT when we toggle HPF/analog input, so just drop that code. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: cs5535audio: drop ec_analog_input flag for OLPC stuffAndres Salomon2008-12-101-8/+1
| | | | | | This is no longer necessary, as we're no longer doing indexed i/o commands. Signed-off-by: Andres Salomon <dilinger@debian.org>
* ALSA: cs5535audio: invert EAPD for OLPC (newer than B3)Andres Salomon2008-12-101-0/+11
| | | | | | | Fix an audible pop described in <http://dev.laptop.org/ticket/977>. Originally based upon fixes by Mitch Bradley and Chris Ball. Signed-off-by: Andres Salomon <dilinger@debian.org>
* ALSA: cs5535audio: Use OLPC/Geode basic infrastructureJordan Crouse2008-12-101-6/+8
| | | | | | | | | | | Use basic infrastructure code; geode_gpio* (rather than indexed i/o EC access), and do an OLPC machine check in olpc_quirk. [dilinger@debian.org: don't return failure in olpc_quirks if !OLPC] [dilinger@debian.org: drop the <B2 workarounds; those machines are EOL'd] Signed-off-by: Jordan Crouse <jordan.crouse@amd.com> Signed-off-by: Andres Salomon <dilinger@debian.org>
* ALSA: cs5535audio: OLPC analog input supportJaya Kumar2008-12-101-0/+113
This is a 2nd cut at adding support for OLPC analog input. Signed-off-by: Jaya Kumar <jayakumar.lkml@gmail.com> Signed-off-by: Andres Salomon <dilinger@debian.org>
