__raw_* and *_relaxed variants are the same, just have a look <asm/io.h>

297 #define readb_relaxed(c) ({ u8  __r = __raw_readb(c); __r; })
298 #define readw_relaxed(c) ({ u16 __r = le16_to_cpu((__force __le16) \
299                                         __raw_readw(c)); __r; })
300 #define readl_relaxed(c) ({ u32 __r = le32_to_cpu((__force __le32) \
301                                         __raw_readl(c)); __r; })
302 
303 #define writeb_relaxed(v,c)     __raw_writeb(v,c)
304 #define writew_relaxed(v,c)     __raw_writew((__force u16) cpu_to_le16(v),c)
305 #define writel_relaxed(v,c)     __raw_writel((__force u32) cpu_to_le32(v),c)
