dt-bindings: clock: Add bindings for DA8XX CFGCHIP clocks

2018-03-20T17:16:26Z

This adds a new binding for the clocks present in the CFGCHIP syscon registers in TI DA8XX SoCs. Signed-off-by: David Lechner Reviewed-by: Rob Herring Signed-off-by: Stephen Boyd

dt-bindings: clock: New bindings for TI Davinci PSC

2018-03-20T17:16:26Z

This adds a new binding for the Power Sleep Controller (PSC) for the mach-davinci family of processors. Note: Although TI Keystone has a very similar PSC, we are not using the existing bindings. Keystone is using a legacy one-node-per-clock binding (actually two nodes if you count the separate reset binding for the same IP block). Also, some davinci LPSCs have quirks that aren't handled by the keystone bindings, so we would be adding one compatible string per clock with quirks instead of just a new compatible string for each controller.

dt-bindings: clock: Add new bindings for TI Davinci PLL clocks

2018-03-20T16:33:08Z

This adds a new binding for the PLL IP blocks in the mach-davinci family of processors. Currently, only da850 has device tree support but these bindings can also work for other SoCs in this family just by adding new compatible strings. Note: Although these PLL controllers are very similar to the TI Keystone SoCs, we are not re-using those bindings. The Keystone bindings use a legacy one-node-per-clock binding. Furthermore, the mach-davinici SoCs have a slightly different PLL register layout and a number of quirks that can't be handled by the existing bindings, so the keystone bindings could not be used as-is anyway.

dt-bindings: clock: ti: add latching support to mux and divider clocks

2018-03-08T09:42:04Z

Certain hardware configurations, like dra76x, have some of the clock registers partitioned in a funky manner that requires the clock control setup to be latched for PRCM to be notified of the change. This is accomplished with a separate control bit under the register. Add support for this clock latching support to divider and mux clocks. Signed-off-by: Tero Kristo Reviewed-by: Rob Herring

dt-bindings: Remove "status" from examples

2017-09-05T15:03:06Z

Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland Signed-off-by: Rob Herring

clk: ti: Add support for dm814x ADPLL

2016-03-02T00:21:25Z

On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The ADPLLs have several dividers and muxes controlled by a shared control register for each PLL. Note that for the clocks to work as device drivers for booting on dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall levels to postcore_initcall" that has already been merged. Also note that this patch does not implement clk_set_rate for the PLL, that will be posted later on when available.

clk: ti: Add support for FAPLL on dm816x

2015-01-20T18:09:07Z

On dm816x the clocks are sourced from a FAPLL (Flying Adder PLL) that does not seem to be used on the other omap variants. There are four instances of the FAPLL on dm816x that each have three to seven child synthesizers. I've set up the FAPLL as a single fapll.c driver. Later on we could potentially have the PLL code generic. To do that, we would have to consider the following: 1. Setting the PLL to bypass mode also sets the child synthesizers into bypass mode. As the bypass rate can also be generated by the PLL in regular mode, there's no way for the child synthesizers to detect the bypass mode based on the parent clock rate. 2. The PLL registers control the power for each of the child syntheriser. Note that the clocks are currently still missing the set_rate implementation so things are still running based on the bootloader values. That's OK for now as most of the outputs have dividers and those can be set using the existing TI component clock code. I have verified that the extclk rates are correct for a few clocks, so adding the set_rate support should be fairly trivial later on. This code is partially based on the TI81XX-LINUX-PSP-04.04.00.02 patches published at: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/TI81XX_04_04/04_04_00_02/index_FDS.html Cc: Brian Hutchinson Cc: Paul Walmsley Cc: Tero Kristo Signed-off-by: Tony Lindgren Signed-off-by: Michael Turquette

CLK: TI: dpll: support OMAP5 MPU DPLL that need special handling for higher frequencies

2014-06-06T17:33:39Z

MPU DPLL on OMAP5, DRA75x, DRA72x has a limitation on the maximum frequency it can be locked at. Duty Cycle Correction circuit is used to recover a correct duty cycle for achieving higher frequencies (hardware internally switches output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)). So provide support to setup required data to handle Duty cycle by the setting up the minimum frequency for DPLL. 1.4GHz is common for all these devices and is based on Technical Reference Manual information for OMAP5432((SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters", and equivalent information from DRA75x, DRA72x documentation(SPRUHP2E, SPRUHI2P).
