Like this:
static inline u32 via_read(struct drm_via_private *dev_priv, u32 reg)
{
return readl((void __iomem *)(dev_priv->mmio->handle + reg));
}
static inline void via_write(struct drm_via_private *dev_priv, u32 reg,
u32 val)
{
writel(val, (void __iomem *)(dev_priv->mmio->handle + reg));
}
static inline void via_write8(struct drm_via_private *dev_priv, u32 reg,
u32 val)
{
writeb(val, (void __iomem *)(dev_priv->mmio->handle + reg));
}
static inline void via_write8_mask_or(struct drm_via_private *dev_priv,
u32 reg, u32 mask)
{
u32 val;
val = readb((void __iomem *)(dev_priv->mmio->handle + reg));
writeb(val | mask, (void __iomem *)(dev_priv->mmio->handle + reg));
}
static inline void via_write8_mask_and(struct drm_via_private *dev_priv,
u32 reg, u32 mask)
{
u32 val;
val = readb((void __iomem *)(dev_priv->mmio->handle + reg));
writeb(val & mask, (void __iomem *)(dev_priv->mmio->handle + reg));
}
Patches are almost ready, but if there is any quick feedback let me
know.
