ASoC: cs35l56: Fixes to handling of ASP1 config
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: This chain fixes some problems with some previous patches for handling the ASP1 config registers. The root of the problem is that the ownership of these registers can be either with the firmware or the driver, and that the chip has to be soft-reset after downloading the firmware. This chain adds and uses a regmap_read_bypassed() function so that the driver can leave the regmap in cache-only until the chip has rebooted, but still poll a register to detect when the chip has rebooted.
