Are we waiting for any other reviews? TI part looks good to me. If everything else is reviewed, Ill merge the series. Please CC me for all the series next time else it is difficult for me to track the comments Thanks and regards, Lokesh > > Changes in v6: > - Remove the 'am3-prcm' driver. > - Add the 'simple-bus' compatible string to the prcm_clocks node. > - Remove the 'am3-scm' driver. > - Add the 'simple-bus' compatible string to the scm_clocks node. > > Changes in v5: > - Create drivers/clk/ti directory. > - Move the clk-ti-mux.c file to drivers/clk/ti and rename it clk-mux.c > - Move the clk-ti-am3-dpll.c file to drivers/clk/ti with the name > clk-am3-dpll.c. > - Move the clk-ti-am3-dpll-x2.c file to drivers/clk/ti with the name > clk-am3-dpll-x2.c. > - Move the clk-ti.c file to drivers/clk/ti with the name clk.c. > - Move the clk-ti.h file to drivers/clk/ti with the name clk.h. > - Move the clk-ti-divider.c file to drivers/clk/ti with the name > clk-divider.c. > - Move the clk-ti-gate.c file to drivers/clk/ti with the name > clk-gate.c. > - Move the clk-ti-ctrl.c file to drivers/clk/ti with the name > clk-ctrl.c. > > Changes in v4: > - Include device_compat.h header for dev_xxx macros. > - Remove a blank line at end of file arch/arm/dts/am33xx-l4.dtsi. > - Update clk_round_rate description. > - Add Sean Anderson review. > - Include device_compat.h header for dev_xxx macros. > - Include device_compat.h header for dev_xxx macros. > - Fix compilation errors on the dev parameter of the dev_xx macros. > - Include device_compat.h header for dev_xxx macros. > - Fix compilation errors on the dev parameter of the dev_xx macros. > - Include device_compat.h header for dev_xxx macros. > - Include device_compat.h header for dev_xxx macros. > - Fix compilation errors on the dev parameter of the dev_xx macros. > - Include device_compat.h header for dev_xxx macros. > - Add Sphinx documentation for dm_flags. > - Convert GD_DM_FLG_* to enum. > - Include device_compat.h header in test/dm/test-fdt.c for dev_xxx macros. > - Include device_compat.h header for dev_xxx macros. > - Include device_compat.h header for dev_xxx macros. > - Include device_compat.h header for dev_xxx macros. > - Add Simon Glass review. > - Include device_compat.h header for dev_xxx macros. > > Changes in v3: > - Remove doc/device-tree-bindings/clock/clock-bindings.txt. > - Remove doc/device-tree-bindings/clock/ti,mux.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Remove doc/device-tree-bindings/clock/ti,dpll.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Remove doc/device-tree-bindings/clock/ti,autoidle.txt. > - Remove doc/device-tree-bindings/clock/ti,divider.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Remove doc/device-tree-bindings/clock/gpio-gate-clock.txt. > - Remove doc/device-tree-bindings/clock/ti,clockdomain.txt. > - Remove doc/device-tree-bindings/clock/ti,gate.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Fix access to registers listed by device tree following resync of > am33xx-clock.dtsi with Linux 5.9-rc7. > - Remove doc/device-tree-bindings/clock/ti,clkctrl.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - doc/device-tree-bindings/arm/omap,prcm.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Add to commit message the references to linux kernel dt binding > documentation. > - Comment dm_flags field in the global_data structure. > - Remove doc/device-tree-bindings/arm/omap,ctrl.txt. > - Remove doc/device-tree-bindings/pinctrl/pinctrl-single.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Adds PWM_TI_EHRPWM dependency on ARCH_OMAP2PLUS in Kconfig. > - Add error message in case of invalid address. > - Remove doc/device-tree-bindings/pwm/ti,ehrpwm.txt. > - Add to commit message the references to linux kernel dt binding > documentation. > - Move Kconfig symbol from drivers/pwm to drivers/bus. > - Remove the domain clock reference from the pwmss nodes of the device > tree in am33xx.dtsi.

Moving dm_flags out of '#ifdef CONFIG_DM' in 'struct global_data', would fix the error but I don't think that's the right way. I think it is more correct to consider dm_flags only when CONFIG_DM is enabled.

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 12e396303c commit.
