regcache_sync: Sync the register cache with the hardware.

: map to configure.

Any registers that should not be synced should be marked as volatile. In general drivers can choose not to use the provided syncing functionality if they so require.

Return a negative value on failure, 0 on success.

regcache_write: Set the value of a given register in the cache.

: map to configure. : The register index. : The new register value.

Return a negative value on failure, 0 on success.
