Hello,
This patch series adds UFS M-PHY and UFS host driver support in MediaTek
chipsets.
In the meantime, re-factors ufshcd_get_pwr_dev_param in vendors' drivers. This
function is for vendors to decide finally agreed attributes for power mode
change if vendors define
their host capability in struct ufs_dev_params. Because it is using by both
ufs-qcom and ufs-hisi and also used in ufs-mediatek in this serious, simply
re-factor it and then every vendors can reuse it.
Changes since v4:
- phy-mtk-ufs:
* Sort name in Kconfig and Makefile
* Drop "inline" and fix symbol name for mphy_set_bit()/mphy_clr_bit().
- dt-bindings: phy-mtk-ufs: Drop "-clk" in clock names.
- dt-bindings: ufs-mediatek:
* Change clock name "ufs-clk" to "ufs".
* Drop vcc related first. VCC control is planned to be added back by
another patch accompanied with VCC/ICC logic fix in ufs common driver.
Changes since v3:
- dt-bindings: Use specific compatible name for both ufs-mediatek and
phy-mtk-ufs, remove interrupt-parent and lanes-per-direction in ufs-mediatek,
and fix descriptions.
Changes since v2:
- Fix header style with SPDX-License-Identifier declaration used.
- Simplify ufs-phy-mtk to single source file since we has one MPHY
version now, and do fixes according to Chunfeng Yun's comments.
- Add dt-bindings of ufs-phy-mtk.
Changes since v1:
- Re-factor ufshcd_get_pwr_dev_param in mediatek/qcom/hisi vendor drivers.
- Introduce ufs-phy-mtk to have a good extension capability for different
power control flows in future different MPHY versions.
- Bind ufs-phy-mtk and hook suitable callbacks in ufs-mediatek driver.
- Use PA_LOCAL_TX_LCC_ENABLE attribute defined in unipro.h instead.
- Do some minor format fixes.
