2023-11-27phy: mediatek: mipi: mt8183: fix minimal supported frequencyMichael Walle1-1/+1
The lowest supported clock frequency of the PHY is 125MHz (see also mtk_mipi_tx_pll_enable()), but the clamping in .round_rate() has the wrong minimal value, which will make the .enable() op return -EINVAL on low frequencies. Fix the minimal clamping value.

Use MediaTek phy's common helper to access registers, then we can remove mipi-dsi's I/O helpers.

2020-11-30phy: mediatek: Move mtk_mipi_dsi_phy driver into drivers/phy/mediatek folderChun-Kuang Hu1-0/+177
mtk_mipi_dsi_phy is currently placed inside mediatek drm driver, but it's more suitable to place a phy driver into phy driver folder, so move mtk_mipi_dsi_phy driver into phy driver folder.
