Date: Mon, 3 Jun 2013 18:06:31 +0100 From: Mark Brown <broonie@...aro.org> To: linux-kernel@...r.kernel.org Cc: Mark Brown <broonie@...aro.org> Subject: [PATCH] regmap: core: Cache all registers by default when cache is enabled Currently all register maps with a cache need to provide a volatile callback since the default is to assume all registers are volatile. This is not sensible if we have a cache so change the default to be fully cached if a cache is provided.
