Subject: [PATCH v2 0/2] regmap: provide simple bitops and use them in a driver
Date: Thu, 28 May 2020 16:22:39 +0200 [thread overview]
Message-ID: <20200528142241.20466-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
I noticed that oftentimes I use regmap_update_bits() for simple bit
setting or clearing. In this case the fourth argument is superfluous as
it's always 0 or equal to the mask argument.
This series proposes to add simple bit operations for setting, clearing
and testing specific bits with regmap.
The second patch uses all three in a driver that got recently picked into
the net-next tree.
The patches obviously target different trees so - if you're ok with
the change itself - I propose you pick the first one into your regmap
tree for v5.8 and then I'll resend the second patch to add the first
user for these macros for v5.9.
v1 -> v2:
- convert the new macros to static inline functions
