phy: samsung: exynos5250-sata: fix missing device put in probe error paths

2022-04-11T17:17:42+00:00

The actions of of_find_i2c_device_by_node() in probe function should be
reversed in error paths by putting the reference to obtained device.

phy: samsung: Fix missing of_node_put() in exynos_sata_phy_probe

2022-04-11T17:16:13+00:00

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

phy: samsung: unify naming and describe driver in KConfig

2021-10-01T06:16:20+00:00

We use everywhere "Samsung" and "Exynos", not the uppercase versions.
Describe better which driver applies to which SoC, to make configuring
kernel for Samsung SoC easier.

phy: samsung-ufs: support exynosauto ufs phy driver

2021-07-20T11:13:10+00:00

This patch adds to support phy-exynosautov9-ufs driver for ExynosAuto v9
series SoCs. The patch adds "samsung,exynosautov9-ufs-phy" compatible.
Unlike previous exynos ufs phy, the chip uses 0x50 offset as
PHY_TRSV_REG_CFG_OFFSET.

phy: samsung-ufs: move phy-exynos7-ufs header

2021-07-20T11:13:10+00:00

Instead of using exynos7 ufs definition in phy-exynos7-ufs.h, we should
put it into phy-exynos7-ufs.c to be included different objects or units.

phy: samsung: Merge Kconfig for Exynos5420 and Exynos5250

2020-12-02T07:05:07+00:00

Exynos5420 variant of USB2 PHY is handled by the same code as the
Exynos5250 one. Introducing a separate Kconfig symbol for it was an
over-engineering, which turned out to cause build break for certain
configurations:

ERROR: modpost: "exynos5420_usb2_phy_config" [drivers/phy/samsung/phy-exynos-usb2.ko] undefined!

Fix this by removing PHY_EXYNOS5420_USB2 symbol and using
PHY_EXYNOS5250_USB2 also for Exynos5420 SoCs.

phy: samsung: Add support for the Exynos5420 variant of the USB2 PHY

2020-11-30T10:50:59+00:00

Exynos5420 differs a bit from Exynos5250 in USB2 PHY related registers in
the PMU region. Add a variant for the Exynos5420 case. Till now, USB2 PHY
worked only because the bootloader enabled the PHY, but then driver messed
USB 3.0 DRD related registers during the suspend/resume cycle.
