Hi folks, This series provides a few cleanups, bug fixes and feature enhancements for the ufs-exynos driver, particularly for gs101 SoC. Regarding cleanup we remove some unused phy attribute data that isn't required when EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR is not set. Regarding bug fixes the check for EXYNOS_UFS_OPT_UFSPR_SECURE is moved inside exynos_ufs_config_smu() which fixes a Serror in the resume path for gs101. Regarding feature enhancements: * Gear 4 is enabled which has higher speeds and better power management. * WriteBooster capability is enabled for gs101 which increases write performance. In v2 of this series additionally I've added following patches 8-11 which add * Clock gating and hibern8 capabilities are enabled for gs101. This leads to a significantly cooler phone when running the upstream kernel on Pixel 6. Approximately 10 degrees cooler after 20 minutes at a shell prompt. * AXI bus on gs101 is correctly configured for write line unique transactions * ACG is set to be controlled by UFS_ACG_DISABLE for gs101 In v1 I mentioned the phy hibern8 series in [1] that is still under discussion however further testing reveals hibern8 feature still works without the additional UFS phy register writes done in [1]. So this series can be merged as is.
