* ARM: at91: replace __raw_{readl, writel} of peripherals with readl, writelAhmad Fatoum2019-05-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Use the potentially endianness-changing readl, writel and siblings directly. They looks prettier and are the correct thing to do, as even if the CPU is in big-endian mode, the peripherals are little-endian. Unlike Linux, barebox readl,writel are the same Linux' {readl,writel}_relaxed (they don't imply memory barriers) and thus there shouldn't be any functional change. Patch was generated by a mass search and replace. I looked it over, adjust some whitespace and further verified by reviewing the output of git diff HEAD~1 --word-diff | \ perl -pe 's/\[-(.*?)__raw_/{+$1/; s/-\]\{\+/+}{+/;' \ -e 's/(\{\+.*?\+\})\1/__ALL_IS_WELL__/' | grep '+}{+' which filters out the common case of lines where a single __raw_{readT,writeT} had its __raw_ prefix stripped without any further changes.

| | | | | | | | Use VERSION register instead of CPU type to determine IP block's version and capabilities. This what corresponding Linux kernel driver does. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
