01c60eafbb clk: rockchip: clk_rk3288: Implement "assign-clock-parent" and "assign-clock-rate"
The RK3288 CRU-node assigns rates to a number of clocks that are not
implemented in the RK3288 clock-driver (but which have been
sufficiently initialised from rkclk_init()): for these clocks, we
implement the gmac clock set parent, but simply ignore the
others' set_rate() operation and return 0 to signal success.

c513e9e1e6 ARM: dts: rk3288: Remove unused LCDC clock assigned
The LCDC assigned rate is 0, it will make boot error,
error log:"pll_para_config: the frequency can not be

correct clock rate setting.

The GMAC in the RK3228 once again is identical to the incarnation in

This adds the RK3368-specific logic necessary to reuse this driver.

f4fcba5c5b clk: implement clk_set_defaults()
Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.

This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.

Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

Cover-letter:
clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS.  This adds the required
plumbing and implements the GMAC case for the RK3399.

a45f17e8b9 rockchip: clk: rk3399: implement set_parent() operation
This implements the (newly added) set_parent() operation for the
RK3399 with a focus on allowing the RGMII clock parent to be
configured via the assigned-clock-parents property of the GMAC node.

This implementation supports only the GMAC (in fact only the RGMII
clock parent) and allows to set this clock's parent either to the
internal SCLK_GMAC or to an external clock input (identifiable by it
providing a 'clock-output-name' of "gmac_clkin").

95f9a7e595 clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()
The logic in clk_get_by_index() may be useful for other properties
than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents'
follows the same model.

This commit refactors clk_get_by_index() by introducing an internal
function clk_get_by_indexed_prop() that allows to specify the name
of the property to process.  The original clk_get_by_index() call
is simply directed through this helper function with the property
name fixed to "clocks".

789edf694c ARM: rmobile: Convert R8A7791 Porter board to DM and DT
Convert the R8A7791 Porter board to DM and DT. This implies mostly
enabling the necessary configuration options and plucking out the
ad-hoc configuration from the board file. Moreover, the pre-reloc
malloc size was increased to allow the clock driver to start up
early without running out of malloc space and the early stack was
moved further up in the DRAM to avoid rewriting U-Boot itself.

Now that we have everything in place to implement the transition scheme,
let's enable it by default.

b39117cad9 sunxi: Transition from the MMC to a FAT-based environment
The current environment has been hardcoded to an offset that starts to be
an issue given the current size of our main U-Boot binary.

By implementing a custom environment location routine, we can always favor
the FAT-based environment, and fallback to the MMC if we don't find
something in the FAT partition. We also implement the same order when
saving the environment, so that hopefully we can slowly migrate the users
over to FAT-based environment and away from the raw MMC one.

Eventually, and hopefully before we reach that limit again, we will have
most of our users using that setup, and we'll be able to retire the raw
environment, and gain more room for the U-Boot binary.
