 * Test method is:
 *
 * 1) Create a mock regmap in cache-only mode so that all writes will be cached.
 * 2) Create dummy wmfw file.
 * 3) Call cs_dsp_power_up() with the bin file.
 * 4) Readback the cached value of registers that should have been written and
 *    check they have the correct value.
 * 5) All the registers that are expected to have been written are dropped from
 *    the cache. This should leave the cache clean.
 * 6) If the cache is still dirty there have been unexpected writes.
