| Series | clk: imx8: add new clock binding for better pm support | expand |
Hi Stephen, This patchset addressed all your new comments. Right now only Patch 2/3 still haven't got any R-b or A-b tags. So still need your help to review. All other patches already got the R-b tags. BTW, for [PATCH v7 02/11] dt-bindings: clock: imx-lpcg: add support to parse clocks from device tree. It was reviewed by Rob/Shawn and you before, however, due to the legacy binding file has been removed and changed to json format. So this patch also updated to json format accordingly based on the former reviewed patch and need a re-review.

Hi Stephen, Would you help look at this? Now only one patch left that still does not have a R-b tag and needs your review. [PATCH v7 03/11] clk: imx: scu: add two cells binding support All other patches already get R-b tags.

Once you give the R-b tags, this series could go to Shawn's tree as another DT patch set also depends on this. Would you help check this left one? [PATCH v7 03/11] clk: imx: scu: add two cells binding support All other patches already get yours R-b tags. Shawn, are you fine with this patch series to go through your tree? Regards Aisheng

This patch series is a preparation for the MX8 Architecture improvement. As for IMX SCU based platforms like MX8QM and MX8QXP, they are comprised of a couple of SS(Subsystems) while most of them within the same SS can be shared. e.g. Clocks, Devices and etc. However, current clock binding is using SW IDs for device tree to use which can cause troubles in writing the common <soc>-ss-xx.dtsi file for different SoCs. This patch series aims to introduce a new binding which is more close to hardware and platform independent and can makes us write a more general drivers for different SCU based SoCs. Another important thing is that on MX8, each Clock resource is associated with a power domain. So we have to attach that clock device to the power domain in order to make it work properly. Further more, the clock state will be lost when its power domain is completely off during suspend/resume, so we also introduce the clock state save&restore mechanism. It's based on latest shanw/for-next branch. The top commit is: 3c1a41dab7b8 Merge branch 'imx/defconfig' into for-next ChangeLog: v6->v7: * addressed all comments from Stephen * rebased to latest shawn/for-next v5->v6: * add scu clk unregister if add provider failed v4->v5: * Address all comments from Stephen v3->v4: * use clk-indices for LPCG to fetch each clks offset from dt v2->v3: * change scu clk into two cells binding * add clk pm patches to ease the understand of the changes v1->v2: * SCU clock changed to one cell clock binding inspired by arm,scpi.txt Documentation/devicetree/bindings/arm/arm,scpi.txt * Add required power domain property * Dropped PATCH 3&4 first, will send the updated version accordingly after the binding is finally determined, Dong Aisheng (11): dt-bindings: firmware: imx-scu: new binding to parse clocks from device tree dt-bindings: clock: imx-lpcg: add support to parse clocks from device tree clk: imx: scu: add two cells binding support clk: imx: scu: bypass cpu power domains clk: imx: scu: allow scu clk to take device pointer clk: imx: scu: add runtime pm support clk: imx: scu: add suspend/resume support clk: imx: imx8qxp-lpcg: add parsing clocks from device tree clk: imx: lpcg: allow lpcg clk to take device pointer clk: imx: clk-imx8qxp-lpcg: add runtime pm support clk: imx: lpcg: add suspend/resume support .../bindings/arm/freescale/fsl,scu.txt | 12 +- .../bindings/clock/imx8qxp-lpcg.yaml | 79 ++++-- drivers/clk/imx/clk-imx8qxp-lpcg.c | 139 +++++++++++ drivers/clk/imx/clk-imx8qxp.c | 136 +++++----- drivers/clk/imx/clk-lpcg-scu.c | 53 +++- drivers/clk/imx/clk-scu.c | 234 +++++++++++++++++- drivers/clk/imx/clk-scu.h | 56 ++++- include/dt-bindings/clock/imx8-lpcg.h | 14 ++ 8 files changed, 620 insertions(+), 103 deletions(-) create mode 100644 include/dt-bindings/clock/imx8-lpcg.h
