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 Signed-off-by: Tero Kristo <t-kristo@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
