sunxi: Add CONFIG_OLD_SUNXI_KERNEL_COMPAT Kconfig option
Add a Kconfig option which users can select when they want to boot older kernels, e.g. the linux-sunxi 3.4 kernels. For now this just forces the pll5 "p" value to 1 (divide by 2) as that is what those kernels are hardcoded too, in the future this may enable further workarounds. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Tom Rini <trini@ti.com> -- Changes in v2: -s/CONFIG_OLD_KERNEL_COMPAT/CONFIG_OLD_SUNXI_KERNEL_COMPAT. -Move the code block setting P(1) for old kernels to where P gets cleared
