Hi, this is a patch set inspired by the recent patch Kai-Heng posted about the HD-audio mic-mute LED control. Currently HD-audio driver deals with the mute and mic-mute LED in several different ways: primarily with the direct callback of vmaster hook and capture sync hook, while another with the LED class device binding. The latter has been used for binding with the platform device LEDs like Thinkpad, Dell, Huawei. And, yet, recently we added our own LED classdev for the mic-mute LED on some HP systems although they are controlled directly with the callback; it's exposed, however, for the DMIC that is governed by a different ASoC driver. This patch set is an attempt to sort out and make them consistent: namely, * All LEDs are now controlled via LED class device * The generic driver provides helper functions to easily build up the LED class dev and the relevant mixer controls * Conversion of the existing framework and clean ups The patches are lightly tested in my side with a couple of machines and also through hda-emu tests. Some devices receive new kcontrols for the mute LED behavior (that have been missing so far), but anything else look good though my tests. thanks, Takashi === Takashi Iwai (13): ALSA: hda: generic: Always call led-trigger for mic mute LED ALSA: hda: generic: Add a helper for mic-mute LED with LED classdev ALSA: hda/realtek: Convert to cdev-variant of mic-mute LED controls ALSA: hda/conexant: Convert to cdev-variant of mic-mute LED controls ALSA: hda/sigmatel: Convert to cdev-variant of mic-mute LED controls ALSA: hda: generic: Drop unused snd_hda_gen_fixup_micmute_led() ALSA: hda: generic: Drop the old mic-mute LED hook ALSA: hda: generic: Add vmaster mute LED helper ALSA: hda/realtek: Use the new vmaster mute LED helper ALSA: hda/conexant: Use the new vmaster mute LED helper ALSA: hda/sigmatel: Use the new vmaster mute LED helper ALSA: hda/realtek: Unify LED helper code ALSA: hda: Let LED cdev handling suspend/resume sound/pci/hda/Kconfig | 9 ++ sound/pci/hda/hda_generic.c | 134 ++++++++++++++++-------- sound/pci/hda/hda_generic.h | 13 ++- sound/pci/hda/patch_conexant.c | 47 ++++----- sound/pci/hda/patch_realtek.c | 220 +++++++++++++++++++--------------------- sound/pci/hda/patch_sigmatel.c | 22 ++-- sound/pci/hda/thinkpad_helper.c | 19 +--- 7 files changed, 248 insertions(+), 216 deletions(-) -- 2.16.4
