Subject: [PATCH v2 0/3] change exynos ufs phy control
Date: Wed, 6 Jul 2022 11:02:52 +0900 [thread overview]
Message-ID: <20220706020255.151177-1-chanho61.park@samsung.com> (raw)
In-Reply-To: CGME20220706020540epcas2p37a8b697af2c6786db9e4ed67cf20a40f@epcas2p3.samsung.com
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
