  dt-bindings: ARM: Mediatek: Document devicetree bindings for clock/reset controllers (2015-03-19 09:15:33 +0100)

----------------------------------------------------------------
This patchset contains the initial common clock support for Mediatek SoCs.
Mediatek SoC's clock architecture comprises of various PLLs, dividers, muxes
and clock gates.

Changes in v8:
- add patch to allow to put parent_name arrays in __initconst
- put parent_name arrays into __initconst

Changes in v7:
- fix duplicate definition/declaration of mtk_register_reset_controller
- fix pd_reg offset of tvdpll
- make clk initialization arrays const

Changes in v6:
- rework PLL support, only a fraction of original size now
- Move binding docs to Documentation/devicetree/bindings/arm/mediatek since
  the units are not really clock specific (they contain reset controllers)

Changes in v5:
- Add reset controller support for pericfg/infracfg
- Use regmap for the gates
- remove now unnecessary spinlock for the gates
- Add PMIC wrapper support as of v3

Changes in v4:
- Support MT8173 platform.
- Re-ordered patchset. driver/clk/Makefile in 2nd patch.
- Extract the common part definition(mtk_gate/mtk_pll/mtk_mux) from
  clk-mt8135.c/clk-mt8173.c to clk-mtk.c.
- Refine code. Rmove unnessacary debug information and unsed defines,
  add prefix "mtk_" for static functions.
- Remove flag CLK_IGNORE_UNUSED and set flag CLK_SET_RATE_PARENT on
  gate/mux/fixed-factor.
- Use spin_lock_irqsave(&clk_ops_lock, flags) instead of mtk_clk_lock.
- Example above include a node for the clock controller itself, followed
  by the i2c controller example above.

Changes in v3:
- Rebase to 3.19-rc1.
- Refine code. Remove unneed functions, debug logs and comments, and fine tune
  error logs.

Changes in v2:
- Re-ordered patchset. Fold include/dt-bindings and DT document in 1st patch.

* [PATCH 1/6] clk: make strings in parent name arrays const

The clk functions and structs declare the parent_name arrays as
'const char **parent_names' which means the parent name strings
are const, but the array itself is not. Use
'const char * const * parent_names' instead which also makes
the array const. This allows us to put the parent_name arrays into
the __initconst section.

* [PATCH 1/6] clk: make strings in parent name arrays const
@ 2015-03-19  8:42   ` Sascha Hauer
  0 siblings, 0 replies; 53+ messages in thread
From: Sascha Hauer @ 2015-03-19  8:42 UTC (permalink / raw)
  To: linux-arm-kernel

The clk functions and structs declare the parent_name arrays as
'const char **parent_names' which means the parent name strings
are const, but the array itself is not. Use
'const char * const * parent_names' instead which also makes
the array const. This allows us to put the parent_name arrays into
the __initconst section.

The pericfg and infracfg units also provide reset lines to several
other SoC internal units. Add support for the reset controller.

It would be nice to have this for more clock types (which of course
shouldn't delay this patch).

Nitpick: 'lock' is very generic. Lockdep will use the variable
name in its output, so it's wise to make locks have better names
if possible. How about mt8135_lock?

Looks ok to me except for the minor nitpick on lock names.

I just renamed this to mt8135_clk_lock/mt8173_clk_lock and resent the
series.

I've already applied the patch, so if you like you can send a
follow up. Perhaps power-controller is more appropriate? I'm not
too worried about it though.

For apmixed this I agree, but the others are also reset controllers, so
I'm not sure if clock-controller is appropriate. Personally I don't care
much, I'll change to whatever you like.

+Mediatek infracfg controller
+============================
+
+The Mediatek infracfg controller provides various clocks and reset
+outputs to the system.
+
+Required Properties:
+
+- compatible: Should be:
+	- "mediatek,mt8135-infracfg", "syscon"
+	- "mediatek,mt8173-infracfg", "syscon"
+- #clock-cells: Must be 1
+- #reset-cells: Must be 1
+
+The infracfg controller uses the common clk binding from
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+The available clocks are defined in dt-bindings/clock/mt*-clk.h.
+Also it uses the common reset controller binding from
+Documentation/devicetree/bindings/reset/reset.txt.
+The available reset outputs are defined in
+dt-bindings/reset-controller/mt*-resets.h
+
+Example:
+
+infracfg: infracfg@10001000 {
+	compatible = "mediatek,mt8173-infracfg", "syscon";
+	reg = <0 0x10001000 0 0x1000>;

+Mediatek pericfg controller
+===========================
+
+The Mediatek pericfg controller provides various clocks and reset
+outputs to the system.
+
+Required Properties:
+
+- compatible: Should be:
+	- "mediatek,mt8135-pericfg", "syscon"
+	- "mediatek,mt8173-pericfg", "syscon"
+- #clock-cells: Must be 1
+- #reset-cells: Must be 1
+
+The pericfg controller uses the common clk binding from
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+The available clocks are defined in dt-bindings/clock/mt*-clk.h.
+Also it uses the common reset controller binding from
+Documentation/devicetree/bindings/reset/reset.txt.
+The available reset outputs are defined in
+dt-bindings/reset-controller/mt*-resets.h
+
+Example:
+
+pericfg: pericfg@10003000 {
+	compatible = "mediatek,mt8173-pericfg", "syscon";
+	reg = <0 0x10003000 0 0x1000>;
+	#clock-cells = <1>;
+	#reset-cells = <1>;
