This is a driver for a block that generates master and bit clocks for
the I2S interface. It's separate from the PMUs that generate clocks for
the peripherals.
Signed-off-by: Lubomir Rintel <lkundrak@xxxxx>
---
Changes since v1:
- Utilize runtime PM along with pm_clk to enable/disable clocks
- Rework the driver to use regular clk_mux, clk_div and clk_gate;
save/restore the registers on PM suspend/resume
- Use #defines for regiser offsets instead of an enum
- Constify some structs
- Remove an extra comma afer a sentinel
- Remove an line break before module_platform_driver()
- Replace __raw_readl()/__raw_writel() with readl()/writel()
- Use clk_add_hw_provider() instead of clk_add_provider()
- Utilize clk_parent_data[] with .fw_name instead of clk_hw[] with
__clk_get_hw(devm_clk_get()) to refer to parent clocks from outside the
audio clock controller
