Subject: [PATCH v10 18/18] arm64: dts: imx8mp: add PLLs to clock controller module (CCM)
Add the PLLs generated by anatop to the clock list of the Clock
Controller Module (CCM) node.
Signed-off-by: Dario Binacchi <dario.binacchi@...rulasolutions.com>
---
Changes in v10:
- Drop the v9 patches:
16/23 dt-bindings: clock: imx8m-clock: support spread spectrum clocking
17/23 clk: imx: pll14xx: support spread spectrum clock generation
17/23 clk: imx8mn: support spread spectrum clock generation
21/23 clk: imx8mp: support spread spectrum clock generation
23/23 clk: imx8mm: support spread spectrum clock generation
Changes in v9:
- Add 'Reviewed-by' tag of Peng Fan for imx8mn platform patches
- Fix building warning raised by the kernel test robot for patch
v8, 11/18 clk: imx: add support for i.MX8MN anatop clock driver
- Add patches for imx8m{m,p} platforms:
- 23/23 clk: imx8mm: support spread spectrum clock generation
- 22/23 clk: imx: add support for i.MX8MM anatop clock driver
- 21/23 clk: imx8mp: support spread spectrum clock generation
- 20/23 clk: imx8mp: rename ccm_base to base
- 19/23 clk: imx: add support for i.MX8MP anatop clock driver
Changes in v8:
- Drop the patches added in version 7:
- 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop
- 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM
- 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM
- 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM
- 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM
Changes in v7:
- Add and manage fsl,anatop property as phandle to the anatop node with
the new patches:
- 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop
- 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM
- 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM
- 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM
- 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM
Changes in v6:
- Merge patches:
10/20 dt-bindings: clock: imx8mm: add binding definitions for anatop
11/20 dt-bindings: clock: imx8mn: add binding definitions for anatop
12/20 dt-bindings: clock: imx8mp: add binding definitions for anatop
to
05/20 dt-bindings: clock: imx8m-anatop: define clocks/clock-names
now renamed
05/18 dt-bindings: clock: imx8m-anatop: add oscillators and PLLs
- Split the patch
15/20 dt-bindings-clock-imx8m-clock-support-spread-spectru.patch
into
12/18 dt-bindings: clock: imx8m-clock: add PLLs
16/18 dt-bindings: clock: imx8m-clock: support spread spectrum clocking
Changes in v5:
- Fix compilation errors.
- Separate driver code from dt-bindings
Changes in v4:
- Add dt-bindings for anatop
- Add anatop driver
- Drop fsl,ssc-clocks from spread spectrum dt-bindings
- New
Changes in v3:
- Patches 1/8 has been added in version 3. The dt-bindings have
been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The
anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a
syscon, so it represents a memory area accessible by ccm
(imx8m-clock.yaml) to setup the PLLs.
- Patches {3,5}/8 have been added in version 3.
- Patches {4,6,8}/8 use ccm device node instead of the anatop one.
Changes in v2:
- Add "allOf:" and place it after "required:" block, like in the
example schema.
- Move the properties definition to the top-level.
- Drop unit types as requested by the "make dt_binding_check" command.
