From: Robert Marko Date: Sat, 5 Feb 2022 22:40:51 +0000 (+0100) Subject: ipq807x: add Qualcomm Atheros IPQ807x target X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b5f32064ed0c3a8b897377ec2fc895dc7a5f1bc8;p=openwrt%2Fstaging%2Fdedeckeh.git ipq807x: add Qualcomm Atheros IPQ807x target Qualcomm Atheros IPQ807x is a modern WiSoC featuring: * Quad Core ARMv8 Cortex A-53 * @ 2.2 GHz (IPQ8072A/4A/6A/8A) Codename Hawkeye * @ 1.4 GHz (IPQ8070A/1A) Codename Acorn * Dual Band simultaneaous IEEE 802.11ax * 5G: 8x8/80 or 4x4/160MHz (IPQ8074A/8A) * 5G: 4x4/80 or 2x2/160MHz (IPQ8071A/2A/6A) * 5G: 2x2/80MHz (IPQ8070A) * 2G: 4x4/40MHz (IPQ8072A/4A/6A/8A) * 2G: 2x2/40MHz (IPQ8070A/1A) * 1x PSGMII via QCA8072/5 (Max 5x 1GbE ports) * 2x SGMII/USXGMII (1/2.5/5/10 GbE) on Hawkeye * 2x SGMII/USXGMII (1/2.5/5 GbE) on Acorn * DDR3L/4 32/16 bit up to 2400MT/s * SDIO 3.0/SD card 3.0/eMMC 5.1 * Dual USB 3.0 * One PCIe Gen2.1 and one PCIe Gen3.0 port (Single lane) * Parallel NAND (ONFI)/LCD * 6x QUP BLSP SPI/I2C/UART * I2S, PCM, and TDMA * HW PWM * 1.8V configurable GPIO * Companion PMP8074 PMIC via SPMI (GPIOS, RTC etc) Note that only v2 SOC models aka the ones ending with A suffix are supported, v1 models do not comply to the final 802.11ax and have lower clocks, lack the Gen3 PCIe etc. SoC itself has two UBI32 cores for the NSS offloading system, however currently no offloading is supported.

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;
