* ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimizationAndres Salomon2009-12-151-7/+19
| | | | | | | | | | | | | | | | | | Previously, OLPC support for the mic extensions was only enabled in the ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was because the old geode GPIO code was written in a manner that assumed CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead include a requirement on GPIOLIB. We use the generic GPIO API rather than the cs553x-specific API.

* ALSA: cs5535audio: ensure MIC Bias/Analog Input bail if not on an OLPC machineAndres Salomon2008-12-101-0/+6

* ALSA: cs5535audio: clean up OLPC codeAndres Salomon2008-12-101-3/+12
| | | | | | | | | | - add copyright info to _olpc.c - minor layout fixes - make Makefile more concise - silence a warning Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* 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

* 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>
