Hi Jean-Jacques,
This is the second of a few series, the goal of which is to facilitate porting drivers from the linux kernel. Most of the series will be about adding managed API to existing infrastructure (GPIO, reset, phy,...)
This particular series is about clocks. It adds a managed API, using the same API as linux. It also fix a use-case where the clock is initialized (rate and/or mux) when it is probed using the assigned-clocks-* properties.
This series when applied on newest -master branch causes build breaks (on for instance mips, bcm):
mips: + bcm968380gerg_ram
+drivers/mtd/nand/raw/built-in.o: In function `devm_clk_get':
+drivers/mtd/nand/raw/brcmnand/brcmnand_compat.c:7: multiple definition of `devm_clk_get'
Travis-CI result: https://travis-ci.org/lmajewski/u-boot-dfu/jobs/600367698
The branch to reproduce: https://github.com/lmajewski/u-boot-dfu/commits/testing
