2018-06-28ALSA: hdac: Remove usage of struct hdac_ext_bus and use hdac_bus insteadRakesh Ughreja
This patch removes the hdac_ext_bus structure. The legacy and enhanced HDaudio capabilities can be handled in a backward-compatible way without separate definitions. Follow-up patches in this series handle the driver definition.

2018-01-26ASoC: Intel: Skylake: Add extended I2S config blob support in Clock driverSriram Periyasamy
Extended I2S config blob supports multiple mclk dividers in NHLT blob. This patch detects whether the I2S blob is legacy or extended based on the signature value and chooses the mclk source and divider accordingly.

2018-01-03ASoC: skl: Fix kernel warning due to zero NHTL entryTakashi Iwai
I got the following kernel warning when loading snd-soc-skl module on Dell Latitude 7270 laptop: memremap attempted on mixed range 0x0000000000000000 size: 0x0 WARNING: CPU: 0 PID: 484 at kernel/memremap.c:98 memremap+0x8a/0x180 Call Trace: skl_nhlt_init+0x82/0xf0 [snd_soc_skl] skl_probe+0x2ee/0x7c0 [snd_soc_skl] .... It seems that the machine doesn't support the SKL DSP gives the empty NHLT entry, and it triggers the warning. For avoiding it, let do the zero check before calling memremap().

2017-12-11ASoC: Intel: Skylake: Re-order some code to silence a warningDan Carpenter
I get a Smatch warning here: sound/soc/intel/skylake/skl-nhlt.c:335 skl_get_ssp_clks() error: testing array offset 'j' after use. The code is harmless, but the checker is right that we should swap these two conditions so we verify that the offset is within bounds before we use it.

2017-12-06ASoC: Intel: Skylake: Do not check dev_type for dmic link typeGuneshwor Singh

2017-11-29ASoC: Intel: Skylake: Parse nhlt and register clock deviceSriram Periyasamy
When NHLT endpoint is present for a SSP then we create clock for that SSP. MCLK is consistent across endpoints and configuration for an SSP, so query only for first endpoint for an SSP. For SCLK/SCLKFS, the best fit is queried from the NHLT configurations which matches the clock rate requested. Best fit is decided based on below: 1. If rate matches with multiple configurations, then the first configuration is selected. 2. If for a selected fs and bits_per_sample, there are multiple endpoint configuration match, then the configuration with max number of channels is selected. So, the user has to set the rate which fits max number of channels So we create a platform device and pass clock information parsed as platform data.

2017-06-07ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()Andy Shevchenko
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. Acked-by: Rafael J.
