[PATCH v3 0/5] support secondary ufs for Exynos Auto v9 SoC

[PATCH v3 0/5] 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.

Changes from v2:
- Exclude dts patchset because they'll be queued by Krzysztof after
  v5.19 merge window.
- 0001-dt-bindings: Add "maxItems: 1" to the first level pmu-syscon
  items as suggested by Krzysztof
- 0002: The patch has been added to clarify the variable name
- 0004: The patch has been added to remove drvdata pointer as suggested
  by Krzysztof

Changes from v1:
- dt-bindings: Correct tab align and add "minItems: 1" to make the second
  cell as optional.
- Add 0001- patch to constify phy_cfg.
- Allocate phy->isol and copy data from drvdata to avoid const qualifier
  error
- Add 0004- patch to apply dt style for ufs0 as Krzysztof's suggestion
- Align tab and apply ufs node naming for device tree nodes

[PATCH v3 1/5] dt-bindings: phy: samsung,ufs-phy: make pmu-syscon as phandle-array

[Chanho Park]

To support secondary ufs phy devices, we need to get an offset value
from pmu-syscon.

I still think this should be array of const pointers to const data, so:
	const struct samsung_ufs_phy_cfg * const *cfgs;
I proposed this in last email.

[PATCH v3 4/5] phy: samsung: ufs: remove drvdata from struct samsung_ufs_phy

[Chanho Park]

To change an offset of pmu_isol, we need to store its data instead of
having drvdata's pointer. The definition of the pmu_isol structure
should be extracted from samsung_ufs_phy_drvdata and rename the name
with samsung_ufs_phy_ prefix.

[PATCH v3 4/5] phy: samsung: ufs: remove drvdata from struct samsung_ufs_phy

[Chanho Park]

To change an offset of pmu_isol, we need to store its data instead of
having drvdata's pointer. The definition of the pmu_isol structure
should be extracted from samsung_ufs_phy_drvdata and rename the name
with samsung_ufs_phy_ prefix.

[PATCH v3 5/5] 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.
