This series is based on 4.5-rc1 and [1], add clock and reset controller
support for Mediatek MT2701.
This series also refined makefile and Kconfig to support configurable
multiple SoC clock support.
changes since v5:
- Rebase to v4.5-rc1 and [1].
- Enable critical clocks for MT2701
- Refine dt-binding documents, add reset controller support for hifsys.
changes since v4:
- Rebase to v4.5-rc1.
- Remove CLK_SET_RATE_PARENT from divider flags.
- Add img_jpgdec_smi clock.
- Move clk/mediatek/Kconfig into menu section in clk/Kconfig.
changes since v3:
- Change the parent of mm_mdp_bls_26m from clk26m to pwm_sel.
changes since v2:
- Fix ethsys definition.
- Replace read-modify-write with regmap_update_bits() in clock operations.
- Move mt2701-resets.h to include/dt-bindings/reset/.
- Add hifsys reset patch from John Crispin.
changes since v1:
- Document MT2701 compatible strings.

Using CLK_OF_DECLARE() for all clock providers is convenient. The convenience includes coding structure and driver init order. The coding structure means we can use a consistency way to add clock providers, so we can reduce errors and apply code generator on clock drivers. The driver init order is another issue. In lpc18xx driver you mentioned in [1], it uses ERR_PTR(-EPROBE_DEFER) to be the place holder for non-early clocks in arch_init (CLK_OF_DECLARE), and then register early and non-early clocks again in module_init. The EPROBE_DEFER place holder is an interesting idea to resolve init order issue. But to register clocks twice on the same clock provider seems not a good idea, although it can still work in current CCF implementation. Is it important to move clock init into platform_driver? If not, I prefer to keep current implementation on MT2701, and look for a better way to init clocks in platform_driver in new SoCs.

So the prepare_count and enable_count will be 2? I'm not sure that this makes sense. If you have different clocks that need to be enabled at different times (due to the split registration scheme that you employ in this driver) then why not pass an array of those clocks into mtk_clk_enable_critical? Anyways, like I mentioned above I think we're close to a solution to handle this in the framework. One question: do you ever want these critical clocks to be gated by a driver, or do you want them always on, forever?

I'm not sure CLK_IS_CRITICAL suitable or not. A clock with CLK_IS_CRITICAL will be prepare_enable when it is registered. But if its parent is not registered into CCF, it will not be enabled even the parent clock register into CCF later. > > + > > static void __init mtk_topckgen_init(struct device_node *node) > > { > > struct clk_onecell_data *clk_data; > > @@ -585,7 +600,7 @@ static void __init mtk_topckgen_init(struct device_node *node) > > return; > > } > > > > - clk_data = mtk_alloc_clk_data(CLK_TOP_NR); > > + top_clk_data = clk_data = mtk_alloc_clk_data(CLK_TOP_NR); > > > > mtk_clk_register_fixed_clks(top_fixed_clks, ARRAY_SIZE(top_fixed_clks), > > clk_data); > > @@ -606,6 +621,8 @@ static void __init mtk_topckgen_init(struct device_node *node) > > if (r) > > pr_err("%s(): could not register clock provider: %d\n", > > __func__, r); > > + > > + mtk_clk_enable_critical(); > > So you call the function here, and ... > > } > > CLK_OF_DECLARE(mtk_topckgen, "mediatek,mt2701-topckgen", mtk_topckgen_init); > > > > @@ -1201,7 +1218,7 @@ static void __init mtk_apmixedsys_init(struct device_node *node) > > struct clk_onecell_data *clk_data; > > int r; > > > > - clk_data = mtk_alloc_clk_data(ARRAY_SIZE(apmixed_plls)); > > + pll_clk_data = clk_data = mtk_alloc_clk_data(ARRAY_SIZE(apmixed_plls)); > > if (!clk_data) > > return; > > > > @@ -1212,6 +1229,8 @@ static void __init mtk_apmixedsys_init(struct device_node *node) > > if (r) > > pr_err("%s(): could not register clock provider: %d\n", > > __func__, r); > > + > > + mtk_clk_enable_critical(); > > ... here as well.

No. After topckgen and apmixedsys initialized, critical clocks' reference count will be 1. There is a guard at the beginning of mtk_clk_enable_critical(): if (!top_clk_data || !pll_clk_data) return; So this function will be only executed when topckgen and apmixedsys init done. We need to enable critical clocks: 1. As early as possible. 2. After critical clocks and their parents are registered into CCF. We need to wait all necessary clock providers because parents of critical clocks must be enabled at the same time. For example, CLK_TOP_AXI_SEL may have different parent on different platforms. We also need to keep new parent clock on if CLK_TOP_AXI_SEL change its parent dynamically. Because we can't ensure the init ordering of clock providers, we can only check all necessary providers are registered or not in each init function. > Anyways, like I mentioned above I think we're close to a solution to > handle this in the framework. > > One question: do you ever want these critical clocks to be gated by a > driver, or do you want them always on, forever? In this patch, these clocks should be always on (in SW view) even if there are other drivers controlling them. If these is a common way to keep critical clocks and their parents on, I would like to use the common way. But the solution in your patch series [0] looks not handle parent clocks well. What's your suggestion to implement critical clocks base on [0]?
