I'd be tempted to just hard-code those bits on in probe() then, but it's not a big deal, so not worth spinning the patch for that.

[alsa-devel] [PATCH 0/3] ALSA: pxa27x: ac97 reset fixes
by Mike Dunn 08 Jan '13

08 Jan '13

AC97 reset is broken on the pxa27x. These patches fix it by addressing multiple problems: - cold reset fails because the GCR register is not set correctly - warm reset fails because some code used to work around a hardware bug is broken - the intent of the work-around code is obfuscated by unfortunate function naming This patch set replaces some earlier individual patches that had some problems. Thanks Robert and Igor. Changelog: v2: - don't specify the LPM flag DRIVE_HIGH in #define for the mfp config - patches 2 and 3 are combined into one patch - mfp level and direction are set only once, during driver initialization Mike Dunn (3): ALSA: pxa2xx: fix ac97 cold reset ALSA: pxa27x: fix ac97 warm reset ALSA: pxa27x: rename pxa27x_assert_ac97reset() arch/arm/mach-pxa/include/mach/mfp-pxa27x.h | 3 ++ arch/arm/mach-pxa/pxa27x.c | 24 ++++++++++++------ sound/arm/pxa2xx-ac97-lib.c | 34 +++++++++++++++++++++----- 3 files changed, 46 insertions(+), 15 deletions(-) -- 1.7.8.6
