[PATCH v3 0/4] Cleanup greybus audio driver

by Vaibhav Agarwal

This patch series include following cleanup changes in GB Audio driver. - Avoid unnecessary checks for le32 variables - Initialize sig_bits before configuring hw_params - Remove junk codec register mapping - Ensure proper byte ordering Next task is to enable build for GB codec driver. However this requires pushing some changes in ASoC framework. Possibly in another two weeks (based on my freetime), I'll try to submit those changes to ASoC mailing list. And once the same are accepted there, I'll share relevant patches for GB Audio codec driver as well. Changes from v2: - patch 1/4 - Update commit message - Mark Greer - Move le32_to_cpu change to patch 4/4 - Mark Greer - patch 3/4 - Remove junk codec register related definitions in .h file - Mark Greer - patch 4/4 - Ensure byte order for the variable missed out in v1/v2 - Mark Greer Changes from v1: - Include review comments from Dan Vaibhav Agarwal (4): staging: greybus: audio: Avoid less than zero check for le32 variable staging: greybus: audio: Initialize sig_bits before configuring hwparams staging: greybus: audio: Cleanup junk codec registers staging: greybus: audio: Ensure proper byte order drivers/staging/greybus/audio_codec.c | 46 +++----------- drivers/staging/greybus/audio_codec.h | 46 -------------- drivers/staging/greybus/audio_module.c | 2 +- drivers/staging/greybus/audio_topology.c | 102 ++++++++++++++++--------------- 4 files changed, 62 insertions(+), 134 deletions(-) -- 2.7.4

Modular phone by Andy Rubin?

by Karim Yaghmour

"Essential's engineers are developing a proprietary connector that serves double duty for charging the battery and expanding the phone's functionality over time, one person familiar with the planning said. The magnetic connector would allow Essential or even third parties to create hardware accessories that add features to the smartphone. For instance, Rubin’s engineers are working on a sphere-shaped camera add-on that shoots high-resolution 360 degree photographs, the person said." https://www.bloomberg.com/news/articles/2017-01-13/andy-rubin-nears-his-com… -- Karim Yaghmour CEO - Opersys inc. / www.opersys.com http://twitter.com/karimyaghmour

[PATCH 0/2] staging: greybus: loopback: Fix two oops paths in gb_loopback

by Bryan O'Donoghue

Alexandre reported a bug in the loopback rmmod path subsequent to a failure in gb_pm_runtime_get_sync - something that can happen when you are developing device-side firmware easily. Doing some cursory rmmod testing on gb_loopback then showed a second (and long standing) error pertaining to removal of gb_dev.root. This series fixes both issues.
