Hi! This revision should work more reliably as it keeps the never-disable handling in the clock driver instead of relying on the semantics of CLK_IGNORE_UNUSED, which still allows clocks to be turned off for power management. This series adds the option for declaring clocks as "never-disable", i.e. clocks that will not be turned on if not used, but also not turned off if unused. It also enables this option for the RWDT clocks in (almost) all SoCs. The point of this is to allow a WDT that has been enabled by the bootloader to survive these events: - deferred probing of the WDT device, which can lead the clock driver to disable the WDT clock until the WDT is re-probed, giving it a blind spot - probe failure in the WDT driver There are a number of Gen2 and RZ/G1 SoCs that have the RWDT clock declared as critical in order to allow SMP bringup code to work. These have been left as they are. CU Uli Changes since v2: - use the term "never-disable" instead of "ignore-unused" - do the handling internally instead of relying on the behavior of CLK_IGNORE_UNUSED Changes since v1: - rename data structures for clarity - squash SoC-specific patches into one per family Ulrich Hecht (3): clk: renesas: cpg-mssr: add support for never-disable clocks clk: renesas: rcar-gen3: mark RWDT clocks as never-disable clk: renesas: rzg2: mark RWDT clock as never-disable drivers/clk/renesas/r8a774a1-cpg-mssr.c | 5 +++++ drivers/clk/renesas/r8a774b1-cpg-mssr.c | 5 +++++ drivers/clk/renesas/r8a774c0-cpg-mssr.c | 5 +++++ drivers/clk/renesas/r8a7795-cpg-mssr.c | 6 +++++- drivers/clk/renesas/r8a7796-cpg-mssr.c | 6 +++++- drivers/clk/renesas/r8a77965-cpg-mssr.c | 5 +++++ drivers/clk/renesas/r8a77970-cpg-mssr.c | 6 +++++- drivers/clk/renesas/r8a77980-cpg-mssr.c | 6 +++++- drivers/clk/renesas/r8a77990-cpg-mssr.c | 5 +++++ drivers/clk/renesas/r8a77995-cpg-mssr.c | 6 +++++- drivers/clk/renesas/renesas-cpg-mssr.c | 10 ++++++++++ drivers/clk/renesas/renesas-cpg-mssr.h | 9 +++++++++ 12 files changed, 69 insertions(+), 5 deletions(-) -- 2.7.4
