Subject: [PATCH v3 0/4] ASoC: codecs: Add support for FourSemi FS2104/5S

v2 -> v3:
.../foursemi,fs2105s.yaml(patch 0002)
- Drop "schema for " in the patch subject
- Delete the description of the property reg
- Restore the property clocks to v1
- Keep the same order as in list of properties

.../Kconfig(patch 0004)
- Write the help of config symbol with at least 4 lines

.../fs210x.c/h(patch 0004)
- Update entries comment to C++ style
- Use linux/gpio/consumer.h instead of linux/of_gpio.h
- Use a private lock instead of a global one
- Delete driver version and log
- Drop checking of pval in fs210x_reg_read
- Drop most of the debug logs and unused codes
- Drop registers dumping in monitor
- Use fsleep instead of usleep_range
- Update mixer to a standard control:
  PCM Playback Volume
- Add 2 new standard controls:
  DAC Mute Switch: Mute/Unmute
  DAC Fade Switch: Fade enable/disable
- Fix errors reported by mixer-test in mixer:
  Effect Scene
- Integrate the operation of reset(sdz) pin into chip init/reset 
- Add DAPM event for playback:
  Start/stop device in DAPM instead of mute_stream
  Start/stop delay works in mute_stream only
- Drop use_pmdown_time in component driver for DAPM event
- Add dai ops startup:
  Report format&sample rates in constraints
- Add dai ops trigger:
  Start device in trigger when we can't obtain/control the bclk clock
- Use description words: PROVIDER, comsumer
- Add a sysfs node for monitor period(fs210x->check_interval_ms)
- Do the initialisations of delayed works and clock in i2c probe
- Prevent new work after the device is suspended
- Update regmap cache type to MAPLE
  Define volatile registers
- Simplify the logic of getting and setting clock
- Simplify the logic of getting and setting reset gpio
- Use dev_err_probe for error logs
- Remove fs210x_parse_platdata and use fs210x_parse_dts in fs210x_init
- Drop null checking for regmap in i2c probe
- Add a suffix(instances id) to dai name
- Drop compatible of "foursemi,fs2104"
- Drop ifdef CONFIG_OF and of_match_ptr
