The mmc_clk has four selection for parent pll. The original
configuration fix the parent to GPLL that causes the mmc_clk can't
assign to a precision of 400KHz.

This pr_err print has some misunderstandings.
Although fractional div is not allowed,
But may be integer or half-divider can be
precisely assigned to the desired frequency.

There is only one dmac of rk1808, but more than 30 peripheral
may use dma, so disable uart and spi dma as default. Enable it
by property below:
dma-names = "tx", "rx";

mmc sample shift is 0 for rk3328 refer to user manaul.
So it's broken if we enable mmc tuning for rk3328.

(cherry picked from commit c4712f27be)
get_modes() callback might be called asynchronously from the DRM core and
it is not synchronized with bridge_enable(), which sets proper runtime PM
state of the main DP device. Fix this by calling pm_runtime_get_sync()
before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and
analogix_dp_transfer() to ensure that main DP device is runtime active
when doing any access to its registers.
This fixes the following kernel issue on Samsung Exynos5250 Snow board:
