Previously, hwmod core has been used for controlling the hwmod level
clocks. This has certain drawbacks, like being unable to share the
clocks for multiple users, missing usecounting and
"ARM: OMAP2+: Change core_initcall
levels to postcore_initcall".
Also note that this patch does not implement clk_set_rate for the
PLL, that will be posted later on when available.

Hi,
This series adds support for hwmod gate clock type, and changes OMAP4
as an example to use the new clock type, converting the existing
hwmod_data clkctrl definitions to clock nodes under device tree.
Some additional magic is required for handling timer clocks, as the
clock driver assumes it ca
Replace the usage of prcm->clkstctrl with main_clk:s provided via DT.
This is done in preparation to get rid of hwmod data from kernel.

Document the new TI module clock type, which is intended to replace the
internal clock control handling within omap_hwmod. Module clock is
effectively a gate clock controlling both interface and functional
clocks for a single hardware IP block.
