2025-04-23reset: rockchip: implement rk3576 lookup tableElaine Zhang
The current DT bindings for the rk3576 clock use a different ID than the one that is supposed to be written to the hardware registers. Thus, we cannot use directly the id provided in the phandle, but rather use a lookup table to correctly setup the hardware. This follows the implementation done in the Linux-Kernel and also how the rk3588 does this both in the Linux-Kernel as well as U-Boot.

2024-01-16clk/qcom: handle resets and clocks in one deviceKonrad Dybcio
Qualcomm's clock controller blocks actually do much more than it says on the tin.. They provide clocks, resets and power domains. Currently, U-Boot requires one to spawn 2 separate devices for controlling clocks and resets, both spanning the same register space. Refactor the code to make it work with just a single DT node, making it compatible with upstream Linux bindings and dropping the dedicated reset driver in favour of including it in the clock driver.

2023-07-20core: read: fix dev_read_addr_size()John Keeping
The behaviour of dev_read_addr_size() is surprising as it does not handle #address-cells and #size-cells but instead hardcodes the values based on sizeof(fdt_addr_t). This is different from dev_read_addr_size_index() and dev_read_addr_size_name() both of which do read the cell sizes from the device tree. Since dev_read_addr_size() is only used by a single driver and this driver is broken when CONFIG_FDT_64BIT does not match the address size in the device tree, fix the function to behave like all of the other similarly named functions. Drop the property name argument as the only caller passes "reg" and this is the expected property name matching the other similarly named functions.

The current DT bindings for the rk3588 clock use a different ID than the one that is supposed to be written to the hardware registers. Thus, we cannot use directly the id provided in the phandle, but rather use a lookup table to correctly setup the hardware. This approach has been implemented already in Linux, by commit : f1c506d152ff ("clk: rockchip: add clock controller for the RK3588") Hence, implement a similar approach using the lookup table, and adapt the existing reset driver to work with SoCs using lookup table. The file rst-rk3588.c has been copied as much as possible from Linux. Adapt the clk rk3588 driver as well to bind the reset driver with the lookup table.

The USB dm tree when using dwc3-generic is the following: USB glue +-- controller (need controller-reset) +-- controller-reset (need syscon-reset) +-- phy The controller needs to deassert "controller-reset" in USB glue before the controller registers are accessed. The glue needs to deassert "syscon-reset" before the glue registers are accessed. The glue itself doesn't have "syscon-reset", so the controller-reset controls "syscon-reset" instead.
