lantiq: Use platform endianness when accessing dwc2 registers
This patch switches calls to readl/writel to their dwc2_readl/dwc2_writel equivalents which preserve platform endianness. This patch is necessary to access dwc2 registers correctly on big endian systems such as the mips based SoCs made by Lantiq. Then dwc2 can be used to replace ifx-hcd driver for Lantiq platforms found e.g. in OpenWrt. The patch was autogenerated with the following commands: $EDITOR core.h sed -i "s/\<readl\>/dwc2_readl/g" *.c hcd.h hw.h sed -i "s/\<writel\>/dwc2_writel/g" *.c hcd.h hw.h Signed-off-by: Antti Seppälä <a.seppala@gmail.com> Signed-off-by: Vincent Pelletier <plr.vincent@gmail.com> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@44675 3c298f89-4303-0410-b956-a3cf2f4a3e73
