Subject: clk: mediatek: add support for gate ID at offset
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=a03174cbfaef9cc8b51429bbde6e27539f428a83;p=u-boot.git

clk: mediatek: add support for gate ID at offset

Add support to clk_gate ops to reference the clk ID at an offset by
using the just introduced gates_offs value from the unified muxes +
gates implementation.

Gate clock that doesn't have gates_offs set won't be affected as the
offset will simply be 0 and won't be offset of any value.
