[PATCH RESEND v1 0/4] dt-binding: clk: prepare for imx8qm clock support

[PATCH RESEND v1 0/4] dt-binding: clk: prepare for imx8qm clock support

[Aisheng Dong]

After a bit more investigation on IMX8QM, it seemed SCU clock can be used
in a similar way as IMX8QXP. So update the binding and driver to be a bit
generic for easily extension of IMX8QM support later.

Dong Aisheng (4):
  dt-bindings: fsl: scu: add fallback compatible string for clock
  dt-bindings: fsl: scu: add imx8qm scu clock support
  clk: imx: scu: add fallback compatible string support
  dt-bindings: imx8-clock: add a53 and a72 clock id

[PATCH RESEND v1 1/4] dt-bindings: fsl: scu: add fallback compatible string for clock

[Aisheng Dong]

SCU clock can be used in a similar way by IMX8QXP and IMX8QM SoCs.
Let's add a "fsl,scu-clk" fallback compatible string to allow other
SoCs to reuse the common part.

No need for the punctuation here. The whole point of one per line is to 
have 1 line changes. Otherwise,

Add a53 and a72 clock id, as there's still no users, we update
IMX_LSIO_MEM_CLK base to start from 6 to allow a53 and a72 clock
id to be continued with a35 clk.

All 3 cores in one chip? If not maybe these should be split or define 
them as cpu cluster x clocks.

Not in one chip.
Here are common clock IDs used for both MX8QXP and MX8QM.
You mean change to something like below?

#define IMX_CPU_CLUSTER_A53_CLK			2
#define IMX_CPU_CLUSTER_A72_CLK			3

What happened to A35? What I'm saying is if the same clock controller
registers are used across chips even if the cores are different, use
the same clock ID. Ideally, clock IDs have some relationship to the
h/w such as their control register address and offset.

To put it another way, don't create a common number space of clock IDs
across SoCs unless they are strictly subsets and supersets of each
other.

Ping...

BTW, as the first two patches change the same firmware binding doc fs.scu.txt.
I'm not sure whether it should go to Shawn's tree for the binding part, or Stephen's clock tree.

Shawn & Stephen,
What's your suggestion?
