2023-08-14clk: imx: imx8ulp: update SPLL2 typePeng Fan
The SPLL2 on iMX8ULP is different with other frac PLLs, it can support VCO from 650Mhz to 1Ghz. Following the changes to pllv4, use the new type IMX_PLLV4_IMX8ULP_1GHZ.

2023-07-19clk: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-04-09clk: imx: imx8ulp: update clk flag for system critical clockJacky Bai
In order to support bus fabric clock frequency changed on the fly, need to update some bus clocks'flags to make sure these clocks'frequency and parent can be changed on the fly. For these clocks, HW can make sure no glitch will be introduced when changing on the fly. In order to support DDR DFS, the HW register bit for DDR_SEL and DDR_DIV clock will be modified by TF-A. So need to update these two clock's flag to make sure that the linux kernel side can correct these clocks' SW state to reflect the actual HW state.

2023-04-09clk: imx: imx8ulp: Add tpm5 clock as critical gate clockJacky Bai
The TPM5 is used for broadcast timer purpose and registered with TIMER_OF_DECLARE. As the clock driver is not ready at that stage, so the TPM5 clock is configured in bootloader(TF-A). if we just remove the TPM5 clock from linux will introduce a risk that the TPM5's parent clock will be gated, then lead to TPM's channel control config can NOT be written into register successfully. Due to the above reason, we still need to add the TPM5 clock into linux clock but register it as a simple critical gate clock to make sure its parent is always on.

2021-11-22clk: imx: imx8ulp: set suppress_bind_attrs to truePeng Fan
The clock driver is registered as platform devices and it is possible to reloading the driver at runtime. But actually the clocks should never be removed to make system work, attempting to bind again would result in a crash, because almost all devices depends on clock to function well.

2021-09-30clk: imx: Add the pcc reset controller support on imx8ulpJacky Bai
On i.MX8ULP, for some of the PCCs, it has a peripheral SW RST bit resides in the same registers as the clock controller. So add this SW RST controller support alongs with the pcc clock initialization. the reset and clock shared the same register, to avoid accessing the same register by reset control and clock control concurrently, locking is necessary, so reuse the imx_ccm_lock spinlock to simplify the code.
