ASoC: Updates for v4.5 - Some more fixes for the topology code, though it is still not final and ready for enabling in production. We really need to get to the point where that can be done. - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come. - New drivers for a number of Imagination Technologies IPs. - Lots of new features and cleanups for the Renesas drivers. - ANC support for WM5110. - New driver for Atmel class D speaker drivers. - New drivers for Cirrus CS47L24 and WM1831. - New driver for Dialog DA7128. - New drivers for Realtek RT5659 and RT56156. - New driver for Rockchip RK3036. # gpg: Signature made Wed 23 Dec 2015 00:36:01 GMT using RSA key ID 5D5487D0 # gpg: Oops: keyid_from_fingerprint: no pubkey # gpg: Oops: keyid_from_fingerprint: no pubkey # gpg: key 00000000 occurs more than once in the trustdb # gpg: key 16005C11: no public key for trusted key - skipped # gpg: key 16005C11 marked as ultimately trusted # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"
