For this, and similar, purposes the +"shared RCGs" will park the RCG on a source clock which is known to be +available. +When the RCG is parked, a safe clock source will be selected and +committed, then the original source would be written back and upon enable +the change back to the unparked source would be committed. + +But starting with SM8350 this fails, as the value in CFG is committed by +the GDSC handshake and without a ticking parent the GDSC enablement will +time out. + +This becomes a concrete problem if the runtime supended state of a +device includes disabling such rcg's parent clock. As the device +attempts to power up the domain again the rcg will fail to enable and +hence the GDSC enablement will fail, preventing the device from +returning from the suspended state. + +This can be seen in e.g. the display stack during probe on SM8350. + +To avoid this problem, the software needs to ensure that the RCG is +configured to a active parent clock while it is disabled. This is done +by caching the CFG register content while the shared RCG is parked on +this safe source. + +Writes to M, N and D registers are committed as they are requested. New +helpers for get_parent() and recalc_rate() are extracted from their +previous implementations and __clk_rcg2_configure() is modified to allow +it to operate on the cached value. + +Fixes: 7ef6f11887bd ("clk: qcom: Configure the RCGs to a safe source as needed") +Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> +Reviewed-by: Stephen Boyd <sboyd@kernel.org> +Link: https://lore.kernel.org/r/20220426212136.1543984-1-bjorn.andersson@linaro.org +--- + drivers/clk/qcom/clk-rcg.h | 2 + + drivers/clk/qcom/clk-rcg2.c | 126 ++++++++++++++++++++++++++++-------- + 2 files changed, 101 insertions(+), 27 deletions(-) + +--- a/drivers/clk/qcom/clk-rcg.h ++++ b/drivers/clk/qcom/clk-rcg.h +@@ -139,6 +139,7 @@ extern const struct clk_ops clk_dyn_rcg_ + * @freq_tbl: frequency table + * @clkr: regmap clock handle + * @cfg_off: defines the cfg register offset from the CMD_RCGR + CFG_REG ++ * @parked_cfg: cached value of the CFG register for parked RCGs + */ + struct clk_rcg2 { + u32 cmd_rcgr;
