* [PATCH 1/4] phy: mediatek: phy-mtk-hdmi: Switch to regmap for mmio access @ 2022-01-03 15:30 AngeloGioacchino Del Regno 2022-01-03 15:30 ` [PATCH 2/4] phy: mediatek: phy-mtk-hdmi: Reorder to remove forward declarations AngeloGioacchino Del Regno ` (3 more replies) 0 siblings, 4 replies; 8+ messages in thread From: AngeloGioacchino Del Regno @ 2022-01-03 15:30 UTC (permalink / raw) To: chunkuang.hu Cc: linux-phy, linux-kernel, dri-devel, kishon, matthias.bgg, vkoul, linux-mediatek, chunfeng.yun, linux-arm-kernel, AngeloGioacchino Del Regno 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.
