Subject: [PATCH RFC 0/2] Introduce BITS_MASK macro

From: Srinivas Kandagatla <srinivas.kandagatla@...com>

This patch series introduces BITS_MASK macro which creates a mask for a given
lsb and msb bit locations. The usage of masks spread over mutiple bits is
becoming very common for example with regmap_update_bits kind of apis. Having a
common macro for this makes much sense and is clean and readable way to encode
the mask rather than having an hex number for a mask.

Second patch is to show an example usage of this new macro in regmap.

Comments ?

Thanks,
srini
