[PATCH v4 0/5] Add i.MX8MQ clock driver

[PATCH v4 0/5] Add i.MX8MQ clock driver

[Abel Vesa]

Third version can be found here:

https://www.spinics.net/lists/arm-kernel/msg671015.html

Changes since v3:
 * Added a composite clock type to get rid of some complexity
   from clk-imx8mq. This new composite clock type will also be
   used by all the imx8 socs that will follow.
 * Added back the reviewed-by tag.

Abel Vesa (1):
  clk: imx: add imx composite clock

Lucas Stach (4):
  dt-bindings: add binding for i.MX8MQ CCM
  clk: imx: add fractional PLL output clock
  clk: imx: add SCCG PLL type
  clk: imx: add clock driver for i.MX8MQ CCM

+* Clock bindings for NXP i.MX8M Quad
+
+Required properties:
+- compatible: Should be "fsl,imx8mq-ccm"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- clocks: list of clock specifiers, must contain an entry for each required
+          entry in clock-names
+- clock-names: should include the following entries:
+    - "ckil"
+    - "osc_25m"
+    - "osc_27m"
+    - "clk_ext1"
+    - "clk_ext2"
+    - "clk_ext3"
+    - "clk_ext4"
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell.  See include/dt-bindings/clock/imx8mq-clock.h
+for the full list of i.MX8M Quad clock IDs.

[PATCH v4 3/5] clk: imx: add SCCG PLL type

[Abel Vesa]

From: Lucas Stach <l.stach@pengutronix.de>

The SCCG is a new PLL type introduced on i.MX8. Add support for this.
The driver currently misses the PLL lock check, as the preliminary
documentation mentions lock configurations, but is quiet about where
to find the actual lock status signal.

[PATCH v4 4/5] clk: imx: add imx composite clock

[Abel Vesa]

Since a lot of clocks on imx8 are formed by a mux, gate, predivider and
divider, the idea here is to combine all of those into one more complex
clock type, therefore moving the complexity inside the composite clock and
outside of the SoC specific clock driver.

You nearly duplicate drivers/clk/clk-composite.c. This seems necessary
because in the hardware we have two dividers instead of a single one as
the generic composite clock type support.

Instead of duplicating the composite clk code you could create your own
clk_ops for the divider which handles both dividers in a single
callback. You could then use the generic composite clk.

When I made the suggestion that we should a create a composite clk I had
assumed you'd come up with a patch which has a single private struct clk_ops
filled in with the gate/mux/rate callbacks which are then open coded in
your driver. I am not convinced this splitting up in three different
(gate/mux/rate) struct clk_ops brings us anything. For example the open
coded gate code is really trivial compared to all this boilerplate code
we need for the generic composite clk. But maybe the maintainers have a
different opinion?

[PATCH v4 5/5] clk: imx: add clock driver for i.MX8MQ CCM

[Abel Vesa]

From: Lucas Stach <l.stach@pengutronix.de>

Add driver for the Clock Control Module found on i.MX8MQ.

This is largely based on the downstream driver from Anson Huang and
Bai Ping at NXP, with only some small adaptions to mainline from me.
