de74257074 CLK: TI: interface: add support for omap2430 specific interface clock
OMAP2430 I2CHS modules require specific hardware ops to be used, so added
a new compatible string for this.

aa76fcf473 CLK: TI: DPLL: add support for omap2 core dpll
OMAP2 has slightly different DPLL compared to later OMAP generations.
This patch adds support for the ti,omap2-dpll-core-clock and also adds
the bindings documentation.

994c41ee0a ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENT
If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.

This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bb and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.

This patch implements set_rate and round_rate for clkoutx2.

Tested on OMAP3430, OMAP3630, OMAP4460.

3cd4a59622 CLK: TI: add support for clockdomain binding
Some OMAP clocks require knowledge about their parent clockdomain for
book keeping purposes. This patch creates a new DT binding for TI
clockdomains, which act as a collection of device clocks. Clockdomain
itself is rather misleading name for the hardware functionality, as at
least on OMAP4 / OMAP5 / DRA7 the clockdomains can be collections of either
clocks and/or IP blocks, thus idle-domain or such might be more appropriate.
For most cases on these SoCs, the kernel doesn't even need the information
and the mappings can be ignored.

f60b1ea5ea CLK: TI: add support for gate clock
This patch adds support for TI specific gate clocks. These behave as basic
gate-clock, but have different ops / hw-ops for controlling the actual
gate, for example waiting until the clock is ready. Several sub-types
are supported:
- ti,gate-clock: basic gate clock with default ops/hwops
- ti,clkdm-gate-clock: clockdomain level gate control
- ti,dss-gate-clock: gate clock with DSS specific hardware handling
- ti,am35xx-gate-clock: gate clock with AM35xx specific hardware handling
- ti,hsdiv-gate-clock: gate clock with OMAP36xx hardware errata handling

registration routine to allow autoidle support. This routine just
checks a couple of device node properties and adds autoidle support
if required, and just passes the registration forward to basic clocks.

ti_dt_clk_init_provider() can now be used to initialize the contents of

and calls the corresponding init function for them.

This patch also introduces a helper function for the TI clock drivers
to get register info from DT and append the master IP info to this.

a8aceccb4d CLK: TI: add DT alias clock registration mechanism
Some devices require their clocks to be available with a specific
dev-id con-id mapping. With DT, the clocks can be found by default
only with their name, or alternatively through the device node of
the consumer. With drivers, that don't support DT fully yet, add
mechanism to register specific clock names.
