2018-03-13ASoC: Intel: Skylake: Disable clock and power gating during FW/LIB downloadSanyog Kale1-1/+6
In order to achieve better DMA performance and reduce download time for firmware and library, it is recommended to disable dynamic clock and power gating. In some scenarios, DMA may wait to accumulate more data and last chunk of data never gets completed if dynamic clock and power gating is kept enabled. This patch adds support to disable/enable dynamic clock and power gating and use it during firmware and library download.

2018-01-26ASoC: Intel: Skylake: Add ssp clock driverSriram Periyasamy1-0/+1
For certain platforms, it is required to start the clocks (mclk/sclk/fs) before the stream start. Example: for few chrome systems, codec needs the mclk/sclk to be enabled early for a successful clock synchronization and for few IVI platforms, clock need to be enabled at boot and should be ON always. Add the required structures and create set_dma_control ipc to enable or disable the clock. To enable sclk without fs, mclk ipc structure is used, else sclkfs ipc structure is used. Clock prepare/unprepare are used to enable/disable the clock as the IPC will be sent in non-atomic context. The clk set_dma_control IPC structures are populated during the set_rate callback and IPC is sent to enable the clock during prepare callback. This patch creates virtual clock driver, which allows the machine driver to use the clock interface to send IPCs to DSP to enable/disable the clocks.

The list of supported pcm configurations from topology manifest would be stored and later selected runtime based on the hw pcm params. For legacy, module data is filled in the 0th index of resource and interface table. To accommodate both models, change the relevant structures and populate them by parsing newly defined tokens.
