[PATCH v4 0/7] arm: mach-snapdragon: Qualcomm clock driver cleanup
This series begins making some headway towards cleaning up Qualcomm platform support in u-boot. The following is a rough overview of the changes:
* Move the Qualcomm clock drivers out of mach-snapdragon and into clk/qcom * Introduce per-platform clock driver configs to decouple Qualcomm platform support from mach-snapdragon targets. * Add the IPQ4019 clock driver, removing it from mach-ipq40xx and introducing the reset map. * Merge the qcom reset driver is into clk/qcom and rework it to be compatible with upstream devicetrees. * A callback model is added so that multiple clock drivers can be compiled in at once. * SDM845 gains support for enabling/disabling all gate clocks (CBC's) by way of a new "gate_clk" abstraction. * Preperatory cleanup work is done to simplify the bringup process for new platforms.
Further details are included in each commit.
The primary goal of this series is to prepare for enabling several new Qualcomm platforms in u-boot as well as additional peripherals, while minimising the amount of copy/pasted board-specific code.
This series conflicts with a previous series introducing support for the Qualcomm RB2 board [1], I plan to resend this initial support pending acceptance of this series and several other cleanups.

// Caleb (they/them)
Clock drivers don't belong here, move them to the right place and declutter mach-snapdragon a bit.
To de-couple these drivers from specific "target" platforms, add additional config options to enable each clock driver gated behind a common CLK_QCOM option and enable them by default for the respective targets. This will make future work easier as we move towards a generic Qualcomm target.

From: Konrad Dybcio konrad.dybcio@linaro.org
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.
Heavily inspired by Renesas code for a similar hw block.
[caleb: moved drivers to clk/qcom, added reset driver and adjusted bind logic. Imported qcom,gcc-ipq4019.h from Linux]

Many gate clocks can be enabled with a single register write, add support for defining these simple gate clocks and add the ones found on SDM845.
While we're here, inline clk_init_uart() into msm_set_rate().

Currently, it isn't possible to build clock drivers for more than one platform due to how the msm_enable() and msm_set_rate() callbacks are implemented.
Extend qcom_clk_data to include function pointers for these and convert all platforms to use them.
Previously, clock drivers relied on include/configs/<board.h> to include the board specific sysmap header, however as most of the header contents are clock driver related, import the contents directly into each clock driver and remove the header. The only exception here is the dragonboard820c board file which includes some pinctrl macros, those are also inlined.

The RCG divider field takes a value of (2*h - 1) where h is the divisor. This allows fractional dividers to be supported by calculating them at compile time using a macro.
However, the clk_rcg_set_rate_mnd() function was also performing the calculation. Clean this all up and consistently use the F() macro to calculate these at compile time and properly support fractional divisors.
Additionally, improve clk_bcr_update() to timeout with a warning rather than hanging the board, and make the freq_tbl struct and helpers common so that they can be reused by future platforms.

The RCG divider field takes a value of (2*h - 1) where h is the divisor. This allows fractional dividers to be supported by calculating them at compile time using a macro.
However, the clk_rcg_set_rate_mnd() function was also performing the calculation. Clean this all up and consistently use the F() macro to calculate these at compile time and properly support fractional divisors.
Additionally, improve clk_bcr_update() to timeout with a warning rather than hanging the board, and make the freq_tbl struct and helpers common so that they can be reused by future platforms.

This series begins making some headway towards cleaning up Qualcomm platform support in u-boot. The following is a rough overview of the changes:
- Move the Qualcomm clock drivers out of mach-snapdragon and into clk/qcom
- Introduce per-platform clock driver configs to decouple Qualcomm platform support from mach-snapdragon targets.
- Add the IPQ4019 clock driver, removing it from mach-ipq40xx and introducing the reset map.
- Merge the qcom reset driver is into clk/qcom and rework it to be compatible with upstream devicetrees.
- A callback model is added so that multiple clock drivers can be compiled in at once.
- SDM845 gains support for enabling/disabling all gate clocks (CBC's) by way of a new "gate_clk" abstraction.
- Preperatory cleanup work is done to simplify the bringup process for new platforms.
