From: Benoit Cousson Date: Wed, 22 Dec 2010 04:08:13 +0000 (-0700) Subject: OMAP4: clock data: Add control for pad_clks_ck and slimbus_clk X-Git-Tag: MMI-PSA29.97-13-9~21439^2~15^2~36 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9b98f5f9e20389c43370539ef3de4aba7cf1d79;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git OMAP4: clock data: Add control for pad_clks_ck and slimbus_clk The gating of pad_clks and slimbus_ck is controlled by the PRCM, but since the clock source is external, this is the SW responsability to gate / un-gate it when the mcpdm or slimbus module need to be used. There is no autogating possible with such external clock. Add SW control to enable / disable this SW gating in the pad_clks_ck and slimbus_clk clock node.
