The USB controller on sc7180 does not retain the state when the system goes into low power state and the GDSC is turned off. This results in the controller reinitializing and re-enumerating all the connected devices (resulting in additional delay while coming out of suspend) Fix this by updating the .pwrsts for the USB GDSC so it only transitions to retention state in low power. Since sc7180 only supports cx (parent of usb gdsc) Retention, there are no cxcs offsets mentioned in order to support the Retention state. Signed-off-by:

GDSCs cannot be transitioned into a Retention state in SW. When either the RETAIN_MEM bit, or both the RETAIN_MEM and RETAIN_PERIPH bits are set, and the GDSC is left ON, the HW takes care of retaining the memory/logic for the domain when the parent domain transitions to power collapse/power off state. On some platforms where the parent domains lowest power state itself is Retention, just leaving the GDSC in ON (without any RETAIN_MEM/RETAIN_PERIPH bits being set) will also transition it to Retention. The existing logic handling the PWRSTS_RET seems to set the RETAIN_MEM/RETAIN_PERIPH bits if the cxcs offsets are specified but then explicitly turns the GDSC OFF as part of _gdsc_disable(). Fix that by leaving the GDSC in ON state. Signed-off-by:

While fixing up the driver I noticed that my IPQ8074 board was hanging after CPUFreq switched the frequency during boot, WDT would eventually reset it. So mark apcs_alias0_core_clk as critical since its the clock feeding the CPU cluster and must never be disabled. Fixes: 5e77b4ef ("clk: qcom: Add ipq6018 apss clock controller") Signed-off-by:

Robert Marko authored
While working on IPQ8074 APSS driver it was discovered that IPQ6018 and IPQ8074 use almost the same PLL and APSS clocks, however APSS driver is currently broken. More precisely apcs_alias0_clk_src is broken, it was added as regmap_mux clock. However after debugging why it was always stuck at 800Mhz, it was figured out that its not regmap_mux compatible at all. It is a simple mux but it uses RCG2 register layout and control bits, so utilize the new clk_rcg2_mux_closest_ops to correctly drive it while not having to provide a dummy frequency table. While we are here, use ARRAY_SIZE for number of parents. Tested on IPQ6018-CP01-C1 reference board and multiple IPQ8074 boards.

An RCG may act as a mux that switch between 2 parents. This is the case on IPQ6018 and IPQ8074 where the APCS core clk that feeds the CPU cluster clock just switches between XO and the PLL that feeds it. Add the required ops to add support for this special configuration and use the generic mux function to determine the rate. This way we dont have to keep a essentially dummy frequency table to use RCG2 as a mux. Signed-off-by:

Replace parent_names in PLLs, secondary muxes and primary muxes with parent_data. For primary muxes there were never any *cl_pll_acd clocks, so instead of adding them, put the primary PLLs in both PLL_INDEX and ACD_INDEX, then make sure ACD_INDEX is always picked over PLL_INDEX when setting parent since we always want ACD when using the primary PLLs.

There is nothing special about the secondary muxes, unlike the primary muxes which need some extra logic to handle ACD and switching between primary PLL and secondary mux sources.
