This series adds support for UFS controller found in FSD SoC.
The HCI is almost same as found on other Exynos SoCs with minor
differences. This also adds the required UFS-PHY driver changes.
Patch 2/6: common change to handle different CDR offsets
*Changes since v3:
- Addressed review comments on patch 6/6 from Chanho
*Changes since v2:
- Addressed review comments from Chanho
- collected reviewed-by, tested-by tags
- rebased on next-20220609
*Changes since v1:
- Addressed review comments from Bart, Krzysztof, Chanho
- collected Ack-by tags
- rebased on next-20220602

Move CDR lock offset to drv data so that it can be extended for other SoCs
which are having CDR lock at different register offset.

This can be reversing changes of below patch.
https://git.kernel.org/pub/scm/linux/kernel/git/phy/linux-phy.git/commit/?h=next&id=f86c1d0a58b1f63a176f537e2f6851be49c20ad4
By suggestion of Krzysztof, I removed drvdata assignment to samsung_ufs_phy struct and moved has_symbol_clk from drvdata to samsung_ufs_phy struct.
However, I forgot to remove drvdata from samsung_ufs_phy struct...
Anyway, you want to get back the drvdata, you may need to add a preceding patch with reconsideration of has_symbol_clk to the drvdata again.
Otherwise, you can simply put cdr_lock_status_offset to the samsung_ufs_phy struct and assign the data from drvdata same as has_symbol_clk and isol.

Chanho Park

Bit[3] of HCI_CLKSTOP_CTRL register is for enabling/disabling MPHY APB
clock. Lets add it to CLK_STOP_MASK, so that the same can be controlled
during clock masking/unmasking.
