[PATCH 1/4] phy: mediatek: phy-mtk-hdmi: Switch to regmap for mmio access

AngeloGioacchino Del Regno angelogioacchino.delregno at collabora.com
Mon Jan 3 15:30:52 UTC 2022


Switch to using the generic regmap API instead of calls to readl/writel
for MMIO register access, removing custom crafted update/set/clear_bits
functions and also allowing us to reduce code size.
