[PATCH v8 00/28] Add DM support for omap PWM backlight
The series was born from the need to manage the PWM backlight of the display connected to my beaglebone board. To hit the target, I had to develop drivers for PWM management which in turn relied on drivers for managing timers and clocks, all developed according to the driver model. My intention was to use the SoC-specific API only at strictly necessary points in the code. My previous patches for migrating the AM335x display driver to the driver model had required the implementation of additional functions outside the concerns of the driver, (settings for dividing the pixel clock rate, configuring the display DPLL rate, ....) not being able to use the API of the related clock drivers. This series shouldn't have repeated the same kind of mistake. Furthermore, I also wanted to fix that kind of forced choice. Almost everything should have been accessible via the driver model API. In the series there are also some patches that could be submitted separately, but which I have however inserted to avoid applying future patches to incorporate them. With this last consideration, I hope I have convincingly justified the large number of patches in the series.
The patch enabling address translation into a CPU physical address from device-tree even in case of crossing levels with #size-cells = <0>, is crucial for the series. The previous implementation was unable to perform the address translation required by the am33xx device tree. I tried to apply in a conservative way as few changes as possible and to verify the execution of all the tests already developed, as well as the new ones I added for the new feature.
The patch series can be cleanly applied to the HEAD of the master which at the time of release points to ab865a8ee5c1a069f72a171270c02c99ccda7bfa commit (Merge tag 'u-boot-imx-20201227' of https://gitlab.denx.de/u-boot/custodians/u-boot-imx).

We can handle the sysc interconnect target module in a generic way for many TI SoCs. Initially let's just enable domain clocks before the children are probed.
The code is loosely based on the drivers/bus/ti-sysc.c of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/bus/ti-sysc.txt

- Revert change on cm_t335_defconfig added on version 7 of the series.
Changes in v7:
- Not all OMAP2 platform need CONFIG_TI_SYSC. Set CONFIG_TI_SYSC as imply and disable it to fix building errors in: nokia_rx51_defconfig cm_t335_defconfig
Changes in v4:
- Include device_compat.h header for dev_xxx macros.

This patch defines a duplicate uclass driver for UCLASS_SIMPLE_BUS which is not allowed. This breaks of-platdata and makes the result non-deterministic.
Can you please change it to be a normal driver instead, not a uclass driver? If you need your own uclass, then you should create one.

Let me do some tests and I will send the patch as soon as possible.

There have been several changes to the am33xx.dtsi, so this patch re-syncs it with Linux.
Let's add proper interconnect hierarchy for l4 interconnect instances with the related ti-sysc interconnect module data as documented in Documentation/devicetree/bindings/bus/ti-sysc.txt of the Linux kernel. With l4 interconnect hierarchy and ti-sysc interconnect target module data in place, we can simply move all the related child devices to their proper location and enable probing using ti-sysc.
The am33xx-clock.dtsi file is the same as that of the Linux kernel, except for the reg property of the node l4-wkup-clkctrl@0. As for the am33xx.dtsi file, all the devices with drivers not yet implemented and those I was able to test with this patch have been moved to am33xx-l4.dtsi. In case of any regressions, problem devices can be reverted by moving them back and removing the related interconnect target module node.

It returns the rate which will be set if you ask clk_set_rate() to set that rate. It provides a way to query exactly what rate you'll get if you call clk_set_rate() with that same argument. So essentially, clk_round_rate() and clk_set_rate() are equivalent except the former does not modify the clock hardware in any way.

The driver manages a register-mapped multiplexer with multiple input clock signals or parents, one of which can be selected as output. It uses routines provided by the common clock framework (ccf).
The code is based on the drivers/clk/ti/mux.c driver of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/mux.txt

The digital phase-locked loop (DPLL) provides all interface clocks and functional clocks to the processor of the AM33xx device. The AM33xx device integrates five different DPLLs: * Core DPLL * Per DPLL * LCD DPLL * DDR DPLL * MPU DPLL
The patch adds support for the compatible strings: * "ti,am3-dpll-core-clock" * "ti,am3-dpll-no-gate-clock" * "ti,am3-dpll-no-gate-j-type-clock" * "ti,am3-dpll-x2-clock"
The code is loosely based on the drivers/clk/ti/dpll.c drivers of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/dpll.txt

The patch adds support for TI divider clock binding. The driver uses routines provided by the common clock framework (ccf).
The code is based on the drivers/clk/ti/divider.c driver of the Linux kernel version 5.9-rc7. For DT binding details see: - Documentation/devicetree/bindings/clock/ti/divider.txt

Until now the clkctrl clocks have been enabled/disabled through platform routines. Thanks to this patch they can be enabled and configured directly by the probed devices that need to use them.

On 30/12/20 4:36 am, Dario Binacchi wrote:
The series was born from the need to manage the PWM backlight of the display connected to my beaglebone board. To hit the target, I had to develop drivers for PWM management which in turn relied on drivers for managing timers and clocks, all developed according to the driver model. My intention was to use the SoC-specific API only at strictly necessary points in the code. My previous patches for migrating the AM335x display driver to the driver model had required the implementation of additional functions outside the concerns of the driver, (settings for dividing the pixel clock rate, configuring the display DPLL rate, ....) not being able to use the API of the related clock drivers. This series shouldn't have repeated the same kind of mistake. Furthermore, I also wanted to fix that kind of forced choice. Almost everything should have been accessible via the driver model API. In the series there are also some patches that could be submitted separately, but which I have however inserted to avoid applying future patches to incorporate them. With this last consideration, I hope I have convincingly justified the large number of patches in the series.
The patch enabling address translation into a CPU physical address from device-tree even in case of crossing levels with #size-cells = <0>, is crucial for the series. The previous implementation was unable to perform the address translation required by the am33xx device tree. I tried to apply in a conservative way as few changes as possible and to verify the execution of all the tests already developed, as well as the new ones I added for the new feature.
The patch series can be cleanly applied to the HEAD of the master which at the time of release points to ab865a8ee5c1a069f72a171270c02c99ccda7bfa commit (Merge tag 'u-boot-imx-20201227' of https://gitlab.denx.de/u-boot/custodians/u-boot-imx).
Changes in v8:
- Imply CONFIG_TI_SYSC only if CONFIG_DM and CONFIG_OF_CONTROL are enabled.
- Revert change on cm_t335_defconfig added on version 7 of the series.
- Revert change on da850-evm-u-boot.dtsi. It was wrong and generated building errors.
Applied to u-boot-ti/for-next branch.
Thanks and regards, Lokesh
