Subject: ARM: imx5: move init hooks into mach-imx5x.c
X-Git-Tag: v5.15~17451^2~22^2~47
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ff4ab2311a902e30cd579339a83679bab944e1bc;p=platform%2Fkernel%2Flinux-starfive.git

ARM: imx5: move init hooks into mach-imx5x.c

These imx5 init_early[late] hooks are called only from mach-imx5x.c.
Let's move them into mach-imx5x.c.

While at it, replace the static mapping in imx51_ipu_mipi_setup() with
dynamic mapping.  Also this function and imx_src_init() do not
necessarily to be called at .init_early hook, so move them into
.init_machine.

The mxc_iomux_v3_init() is dropped from imx51_init_early() in the
moving, since it's only needed by non-DT boot.
