[PATCH v2 0/3] change exynos ufs phy control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since commit 1599069a62c6 ("phy: core: Warn when phy_power_on is called
before phy_init"), below warning has been reported.

phy_power_on was called before phy_init

To address this, we need to remove phy_power_on from
exynos_ufs_phy_init.

The first patch is for changing phy clocks manipulation from controlling
each symbol/ref clocks to clk_bulk APIs. The second patch is for making
power on/off sequences between pmu isolation and clk control.
Finally, the third patch changes the phy on/off and init sequences from
ufs-exynos host driver.

Changes since v1:
- Add Krzysztof's R-B tags for #1 / #2 patches
- Get back the error check of phy_power_on

Chanho Park (3):
  phy: samsung-ufs: convert phy clk usage to clk_bulk API
  phy: samsung-ufs: ufs: change phy on/off control
  ufs: ufs-exynos: change ufs phy control sequence
