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 -Reviewed-by: Stephen Boyd -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;
