[PATCH 0/4] support secondary ufs for Exynos Auto v9 SoC

[PATCH 0/4] support secondary ufs for Exynos Auto v9 SoC

[Chanho Park]

To support ufs #1 for Exynos Auto v9 SoC, we need to control its own pmu
register. So, we need to specify the offset of the register via an
argument of syscon node.
Regarding UFS HCI driver, we need to specify different sysreg
configuration for UFS #1's io coherency setting.

You made offset required, not optional.  You need minItems:1 on the
level of second "items".

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

[PATCH 2/4] phy: samsung: ufs: support secondary ufs phy

[Chanho Park]

To support secondary ufs phy device, we need to get an offset for phy
isolation from the syscon DT node. If the first index argument of the
node is existing, we can read the offset value and set it as isol->offset.
To allow this, we should drop the const qualifier of struct pmu_isol.

No casts are needed for proper code. If you need it - code is not proper.

To change a value of phy->isol, I need to allocate its own isol data and copying whole data from drvdata instead of using drvdata->isol pointer.
