From 12309428c27737c21735fb28540c6c6f69f632f6 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Wed, 28 Oct 2020 14:58:58 +0200 Subject: clk: imx: gate2: Remove the IMX_CLK_GATE2_SINGLE_BIT special case This was a hack which would allow multiple HW gates to be controlled by a single bit. The only user of this is the imx_dev_clk_hw_gate_shared which is not used anywhere as of now. Basically, complicates the logic of the driver for no reason.
