Hi Mike, Stephen, et al.,
This series adds a new driver for the Renesas CPG (Clock Pulse Generator) and MSSR (Module Standby and Software Reset) blocks for R-Car H3 (r8a7795). This is supposed to be more in-line with current CCF best practices, and allows expansion to cover the module reset functionality in the future. This drivers follows the DT bindings in Documentation/devicetree/bindings/clock/renesas,cpg-mssr.txt, which have been accepted in clk/clk-next. Support for other SoCs may be added later.
- Patch 1 reworks configuration after the removal of shmobile-legacy, and prepares for the advent of arm64 support, where CONFIG_ARCH_SHMOBILE_MULTI is not defined. - Patch 2 makes clock-output-names optional in the DIV6 driver. This is a bit unrelated, but I had sent this patch before, and there's a contextual dependency, - Patch 3 prepares the existing DIV6 driver for reuse, - Patch 4 introduces the new CPG/MSSR driver core, to be used by several SoC-specific drivers, - Patch 5 introduces the new r8a7795-specific driver.
Compared to v5, only the r8a7795-specific driver (patch 5) received a few bug fixes and enhancements. More detailed changelog information is available in the individual patches.
For your convenience, I pushed these patches and its dependencies to the topic/cpg-mssr-v6 branch of my renesas-drivers repository at https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git/log/?h=topic/cpg-mssr-v6.
A full integration for R-Car Gen3 is available in the topic/gen3-latest branch.
Thanks!
