[PATCH v12 00/10] Mediatek MT8183 scpsys support

[Weiyi Lu]

This series is based on v5.5-rc1

changes since v11:
- re-order patches "Remove infracfg misc driver support" and "Add multiple step bus protection"
- add cap MTK_SCPD_SRAM_ISO for extra sram control
- minor coding sytle fixes and reword commit messages

changes since v10:
- squash PATCH 04 and PATCH 06 in v9 into its previous patch
- add "ignore_clr_ack" for multiple step bus protection control to have a clean definition of power domain data
- keep the mask register bit definitions and do the same for MT8183

changes since v9:
- add new PATCH 04 and PATCH 06 to replace by new method for all compatibles
- add new PATCH 07 to remove infracfg misc driver
- minor coding sytle fix

changes since v7:
- reword in binding document [PATCH 02/14]
- fix error return checking bug in subsys clock control [PATCH 10/14]
- add power domains properity to mfgcfg patch [PATCH 14/14] from
  https://patchwork.kernel.org/patch/11126199/

changes since v6:
- remove the patch of SPDX license identifier because it's already fixed

changes since v5:
- fix documentation in [PATCH 04/14]
- remove useless variable checking and reuse API of clock control in [PATCH 06/14]
- coding style fix of bus protection control in [PATCH 08/14]
- fix naming of new added data in [PATCH 09/14]
- small refactor of multiple step bus protection control in [PATCH 10/14]

changes since v4:
- add property to mt8183 smi-common
- seperate refactor patches and new add function
- add power controller device node

[PATCH v12 02/10] dt-bindings: soc: Add MT8183 power dt-bindings

[Weiyi Lu]

Add power dt-bindings of MT8183 and introduces "BASIC" and
"SUBSYS" clock types in binding document.
The "BASIC" type is compatible to the original power control with
clock name [a-z]+[0-9]*, e.g. mm, vpu1.
The "SUBSYS" type is used for bus protection control with clock
name [a-z]+-[0-9]+, e.g. isp-0, cam-1.

[PATCH v12 02/10] dt-bindings: soc: Add MT8183 power dt-bindings

[Weiyi Lu]

Add power dt-bindings of MT8183 and introduces "BASIC" and
"SUBSYS" clock types in binding document.
The "BASIC" type is compatible to the original power control with
clock name [a-z]+[0-9]*, e.g. mm, vpu1.
The "SUBSYS" type is used for bus protection control with clock
name [a-z]+-[0-9]+, e.g. isp-0, cam-1.

[PATCH v12 03/10] soc: mediatek: Add basic_clk_name to scp_power_data

[Weiyi Lu]

Try to stop extending the clk_id or clk_names if there are
more and more new BASIC clocks. To get its own clocks by the
basic_clk_name of each power domain.
And then use basic_clk_name strings for all compatibles, instead of
mixing clk_id and clk_name.

[PATCH v12 03/10] soc: mediatek: Add basic_clk_name to scp_power_data

[Weiyi Lu]

Try to stop extending the clk_id or clk_names if there are
more and more new BASIC clocks. To get its own clocks by the
basic_clk_name of each power domain.
And then use basic_clk_name strings for all compatibles, instead of
mixing clk_id and clk_name.

[PATCH v12 03/10] soc: mediatek: Add basic_clk_name to scp_power_data

[Weiyi Lu]

Try to stop extending the clk_id or clk_names if there are
more and more new BASIC clocks. To get its own clocks by the
basic_clk_name of each power domain.
And then use basic_clk_name strings for all compatibles, instead of
mixing clk_id and clk_name.

[PATCH v12 04/10] soc: mediatek: Remove infracfg misc driver support

[Weiyi Lu]

The functions provided by infracfg misc driver have no other user except
the scpsys driver so move those into scpsys driver directly.
And then, remove infracfg misc drvier which is no longer being used.
BTW, in next patch, we're going to extend the bus protection functions
with more customized arguments.

[PATCH v12 04/10] soc: mediatek: Remove infracfg misc driver support

[Weiyi Lu]

The functions provided by infracfg misc driver have no other user except
the scpsys driver so move those into scpsys driver directly.
And then, remove infracfg misc drvier which is no longer being used.
BTW, in next patch, we're going to extend the bus protection functions
with more customized arguments.

[PATCH v12 05/10] soc: mediatek: Add multiple step bus protection control

[Weiyi Lu]

Both MT8183 & MT6765 have more control steps of bus protection
than previous project. And there add more bus protection registers
reside at infracfg & smi-common.
Extend function to support multiple step bus protection control
with more customized arguments.
And then use bp_table for bus protection of all compatibles,
instead of mixing bus_prot_mask and bus_prot_reg_update.

[PATCH v12 05/10] soc: mediatek: Add multiple step bus protection control

[Weiyi Lu]

Both MT8183 & MT6765 have more control steps of bus protection
than previous project. And there add more bus protection registers
reside at infracfg & smi-common.
Extend function to support multiple step bus protection control
with more customized arguments.
And then use bp_table for bus protection of all compatibles,
instead of mixing bus_prot_mask and bus_prot_reg_update.

[PATCH v12 05/10] soc: mediatek: Add multiple step bus protection control

[Weiyi Lu]

Both MT8183 & MT6765 have more control steps of bus protection
than previous project. And there add more bus protection registers
reside at infracfg & smi-common.
Extend function to support multiple step bus protection control
with more customized arguments.
And then use bp_table for bus protection of all compatibles,
instead of mixing bus_prot_mask and bus_prot_reg_update.

[PATCH v12 06/10] soc: mediatek: Add subsys clock control for bus protection

[Weiyi Lu]

For the bus protection operations, some subsys clocks need to be enabled
before releasing the protection, and vise versa.
But those subsys clocks could only be controlled once its corresponding
power domain is turned on first.
In this patch, we add the subsys clock control into its relavent steps.

[PATCH v12 07/10] soc: mediatek: Add extra sram control

[Weiyi Lu]

For some power domains like vpu_core on MT8183 whose sram need to
do clock and internal isolation while power on/off sram.
We add a cap "MTK_SCPD_SRAM_ISO" to judge if we need to do
the extra sram isolation control or not.

[PATCH v12 09/10] arm64: dts: Add power controller device node of MT8183

[Weiyi Lu]

Add power controller node and smi-common node for MT8183
In scpsys node, it contains clocks and regmapping of
infracfg and smi-common for bus protection.

[PATCH v12 09/10] arm64: dts: Add power controller device node of MT8183

[Weiyi Lu]

Add power controller node and smi-common node for MT8183
In scpsys node, it contains clocks and regmapping of
infracfg and smi-common for bus protection.
