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.

Exynos5440 SoC support has been dropped since commit 8c83315da1cf ("ARM: dts: exynos: Remove Exynos5440"). Rework this driver to support PCIe PHY variant found in the Exynos5433 SoCs.

phy: samsung: Use readl_poll_timeout function

2020-08-23T14:06:37+00:00

Instead of a busy waiting while loop using udelay use readl_poll_timeout function to check the condition is met or timeout occurs in crport_handshake function. readl_poll_timeout is called in non atomic context so it safe to sleep until the condition is met.
