(was: "clk: renesas: cpg-mssr: add never-disable option") Hi! The purpose of this series 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 Following a suggestion by Geert, this revision, instead of adding another list of clocks with special handling, changes the semantics of the crit_mod_clks[] array slightly by only marking clocks critical that are enabled at boot time. That way it can be used for RWDT without forcing the clock on unnecessarily. The other existing user of crit_mod_clks[] (INTC-AP) is always on at boot time and should thus not be affected by this change. There are a number of Gen2 and RZ/G1 SoCs that have the RWDT clock declared as critical already in order to allow SMP bringup code to work. That should still work with this series applied, assuming that the WDT clock is on at boot time. CU Uli Changes since v3: - drop separate array, add RWDT to crit_mod_clks[] - only mark clocks as critical if they are enabled on boot 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: mark clocks as critical only if on at boot clk: renesas: rcar-gen3: mark RWDT clocks as critical clk: renesas: rzg2: mark RWDT clock as critical drivers/clk/renesas/r8a774a1-cpg-mssr.c | 1 + drivers/clk/renesas/r8a774b1-cpg-mssr.c | 1 + drivers/clk/renesas/r8a774c0-cpg-mssr.c | 1 + drivers/clk/renesas/r8a7795-cpg-mssr.c | 2 +- drivers/clk/renesas/r8a7796-cpg-mssr.c | 2 +- drivers/clk/renesas/r8a77965-cpg-mssr.c | 1 + drivers/clk/renesas/r8a77970-cpg-mssr.c | 2 +- drivers/clk/renesas/r8a77980-cpg-mssr.c | 2 +- drivers/clk/renesas/r8a77990-cpg-mssr.c | 1 + drivers/clk/renesas/r8a77995-cpg-mssr.c | 2 +- drivers/clk/renesas/renesas-cpg-mssr.c | 17 +++++++++-------- 11 files changed, 19 insertions(+), 13 deletions(-) -- 2.20.1
