2013-06-17ARM: imx: remove MLB PLL from pllv3Jiada Wang
MLB PLL should be handled internally in MLB driver, so remove it from pllv3. Signed-off-by: Jiada Wang <jiada_wang@mentor.com> CC: Dirk Behme <dirk.behme@de.bosch.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: i.MX5: Allow DT clock providersMartin Fuzzey
Currently clock providers defined in the DT are not registered on i.MX5 platforms since of_clk_init() is not called. This is not a problem for the SOC's own clocks, which are registered in code, but prevents the DT being used to define clocks for external hardware. Fix this by calling of_clk_init() and actually using the DT to obtain the 4 SOC fixed clocks. These are already defined in the DT but were previously just used to manually obtain the rate. Fall back to the old scheme for non DT platforms. Since the same method may be useful for other i.MX platforms implement the imx_obtain_fixed_clock() function in common code. Actually changing other i.MX platforms to use this should be done later by someone with access to the appropriate hardware.

2013-04-12ARM i.MX: Add imx_clk_divider_flags and imx_clk_mux_flagsPhilipp Zabel
The default is for dividers to set CLK_SET_PARENT_RATE and for muxes to not set that flag. In the LDB clock tree, we need the opposite, so add functions to create divider and mux clocks with configurable flags.

2012-11-22ARM i.MX6: remove gate_mask from pllv3Sascha Hauer
Now that the additional enable bits in the enet PLL are handled as gates, the gate_mask is identical for all plls. Remove the gate_mask from the code and use the BM_PLL_ENABLE bit for enabling/disabling the PLL. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Shawn Guo <shawn.guo@linaro.org>

2012-05-02ARM i.MX: Add common clock support for 2bit gateSascha Hauer
This gate consists of two bits: 0b00: clk disabled 0b01: clk enabled in run mode and disabled in sleep mode 0b11: clk enabled Currently only disabled and enabled are supported. As it's unlikely that we find something like this in another SoC create a i.MX specific clk helper for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
