Hello Stephen,

given that I don't succeed in getting any feedback for my patch set, I'm
trying with a pull request today. It would be really great if this pull
request made it finally in for the next merge window.

The changes are not as bad or complex as the diffstat suggests. The
first patch contains all the complexity and only has
 1 file changed, 50 insertions(+), 17 deletions(-)
. The second patch makes use of this and just adds kernel-doc, four
functions that are one-line wrappers around the newly introduced
__devm_clk_get() function in the first patch and dummy implementations
for the !CONFIG_HAVE_CLK case.

The following changes since commit 6efb943b8616ec53a5e444193dccf1af9ad627b5:

  Linux 5.13-rc1 (2021-05-09 14:17:44 -0700)

  clk: Provide new devm_clk_helpers for prepared and enabled clocks (2021-05-11 14:20:13 +0200)

----------------------------------------------------------------
New variants of devm_clk_get() for prepared and enabled clocks

These two patches create a set of new devm helpers that return clocks
already prepared or prepared-and-enabled. The automatic cleanup cares
for unpreparing and disabling+unpreparing respectively.

This allows to simplify various drivers as was demonstrated with
additional patches sent with the various revisions of this patch set.
See
https://lore.kernel.org/r/20210510174142.986250-1-u.kleine-koenig@pengutronix.de
for the last submission round. This pull request doesn't contain these
patches though.
