[-- Attachment #1.1: Type: text/html, Size: 2539 bytes --]

[-- Attachment #1.2: Type: text/plain, Size: 1585 bytes --]

From: Argus Lin <argus.lin@mediatek.com>

Here's version 5 of the patch series, include 4 patches:
1. fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
2. add pwrap driver for mt6797 SoCs.
3. add mt6351 support for mt6797 SoCs.
4. remove caps flag at patch V4 and keep to use has_bridge.

Changes from v3 to v4:
1)add caps flag for pwrap to explain pwrap's capability.
2)remove has_bridge flag, replace by caps flag.
3)add int1_en_all flag for new interrupt.
4)add pwrap drivers for mt6797 SoCs.
5)fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
6)add mt6351 support for mt6797 SoCs.

Changes from v2 to v3:
1)adjust upstream patch sequence.
2)fix build error for new filed at pmic_wrapper_type.
3)adjust pmic_type enum sequence.

Changes from v1 to v2:
1) add new capability field and MARCO for different pwrap series, the capability include BRIDGE, RESET, DCM, PRIORITY_SEL and INT1_EN.
2) add starvaction for mt6797 pwrap.
3) add INT1 interrupt to handle starvaction and request exception.

Please don't put info like "We fix it before merge PMIC_mt6351 driver." in the
commit message. You can see this from the git log later and it does not add any
value.

[PATCH V5 3/4] soc: mediatek: pwrap: add pwrap driver for mt6797 SoCs

[argus.lin]

[-- Attachment #1.1: Type: text/html, Size: 4035 bytes --]

[-- Attachment #1.2: Type: text/plain, Size: 3067 bytes --]

From: Argus Lin <argus.lin@mediatek.com>

mt6797 is a highly integrated SoCs, it uses mt6351 for power management.
We need to add pwrap driver to access mt6351. Pwrap of mt6797 support
dynamic priority meichanism, sequence monitor and starvation mechanism
to make transaction more reliable.

This is drivers differs vastly from V4, but I can't find any explanation why.
Can you please elaborate. For the record the explanation should have been done
in the cover letter.

[PATCH V5 4/4] soc: mediatek: pwrap: add mt6351 driver for mt6797 SoCs

[argus.lin]

[-- Attachment #1.1: Type: text/html, Size: 3222 bytes --]

[-- Attachment #1.2: Type: text/plain, Size: 2248 bytes --]

From: Argus Lin <argus.lin@mediatek.com>

MT6351 is a new power management IC and it is used for mt6797 SoCs. We
need to add mt6351_regs for pmic register mapping and pmic_mt6351 for
accessing register.

[PATCH V5 0/4] Pwrap: Mediatek pwrap driver for mt6797

[Argus Lin]

[-- Attachment #1.1: Type: text/html, Size: 2682 bytes --]

[-- Attachment #1.2: Type: text/plain, Size: 1734 bytes --]

Here's version 5 of the patch series, include 4 patches:
1. Fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
2. Add pwrap driver for mt6797 SoCs.
3. Add mt6351 support for mt6797 SoCs.
4. A big change from V4 to V5 is we remove INT1 interrupt declaration since
it is only for debug purpose. The PWRAP_RDDMY, RESET and DCM can use legacy
setting, it is backwards compatible. The new caps flag declaration is not
needed, just remove it.

Changes from v3 to v4:
1)add caps flag for pwrap to explain pwrap's capability.
2)remove has_bridge flag, replace by caps flag.
3)add int1_en_all flag for new interrupt.
4)add pwrap drivers for mt6797 SoCs.
5)fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
6)add mt6351 support for mt6797 SoCs.

Changes from v2 to v3:
1)adjust upstream patch sequence.
2)fix build error for new filed at pmic_wrapper_type.
3)adjust pmic_type enum sequence.

Changes from v1 to v2:
1) add new capability field and MARCO for different pwrap series, the capability include BRIDGE, RESET, DCM, PRIORITY_SEL and INT1_EN.
2) add starvaction for mt6797 pwrap.
3) add INT1 interrupt to handle starvaction and request exception.

PWRAP_DEW_CIPHER_LOAD and PWRAP_DEW_CIPHER_START only exist at
PMIC_mt6397 datasheet. We fix it before merge PMIC_mt6351 driver.

PWRAP_DEW_CIPHER_LOAD and PWRAP_DEW_CIPHER_START only exist at
PMIC_mt6397 datasheet. We fix it before merge PMIC_mt6351 driver.

[PATCH V5 0/4] Pwrap: Mediatek pwrap driver for mt6797

[argus.lin-NuS5LvNUpcJWk0Htik3J/w]

From: Argus Lin <argus.lin-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

Here's version 5 of the patch series, include 4 patches:
1. Fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
2. Add pwrap driver for mt6797 SoCs.
3. Add mt6351 support for mt6797 SoCs.
4. A big change from V4 to V5 is we remove INT1 interrupt declaration since
it is only for debug purpose. The PWRAP_RDDMY, RESET and DCM can use legacy
setting, it is backwards compatible. The new caps flag declaration is not
needed, just remove it.

Changes from v3 to v4:
1)add caps flag for pwrap to explain pwrap's capability.
2)remove has_bridge flag, replace by caps flag.
3)add int1_en_all flag for new interrupt.
4)add pwrap drivers for mt6797 SoCs.
5)fix bug at cipher init for
5ae48040aa47 ("soc: mediatek: PMIC wrap: add mt6323 slave support")
6)add mt6351 support for mt6797 SoCs.

Changes from v2 to v3:
1)adjust upstream patch sequence.
2)fix build error for new filed at pmic_wrapper_type.
3)adjust pmic_type enum sequence.

Changes from v1 to v2:
1) add new capability field and MARCO for different pwrap series, the capability include BRIDGE, RESET, DCM, PRIORITY_SEL and INT1_EN.
2) add starvaction for mt6797 pwrap.
3) add INT1 interrupt to handle starvaction and request exception.
