ASoC: samsung: fsd: audio support for FSD SoC
Merge series from Padmanabhan Rajanbabu <p.rajanbabu@samsung.com>: This patch series enables audio support on FSD SoC. Changes in v4: 1. Rebased and addressed review comments provided for v3. Changes in v3: 1. Addressed all the review comments provided for v2 patch. 2. Fixed compilation warnings reported by kernel test robot. Changes in v2: 1. New compatible added in Exynos I2S driver for FSD platform. 2. Added Fixup support for Exynos I2S CPU DAI. 3. Migration of manual PSR, OPCLK configuration to Exynos CPU DAI driver as fixup. 4. Migrated from dedicated sound card to simple audio card. 5. Support added for tlv320aic3x-i2c codec on FSD platform. Changes in v1: 1. Add TDM support on samsung I2S interface. 2. Allow sound card to directly configure I2S prescaler divider instead of calculating it from frame clock. 3. The sound card support for FSD SoC which utilizes samsung I2S interface as CPU DAI.
