2019-10-07ARM: dts: keystone-clocks: add input fixed clocksGrygorii Strashko1-0/+27
Add set of fixed, external input clocks definitions for TIMI0, TIMI1, TSREFCLK clocks. Such clocks can be used as reference clocks for some HW modules (as cpts, for example) by configuring corresponding clock muxes. For these clocks real frequencies have to be defined in board files.

2017-12-17ARM: dts: keystone-clocks: Add missing unit name to clock nodes that have regsNishanth Menon1-26/+26
Add the control register as the base for the clock nodes which are missing them. This squashes some 78 warnings of the effect when built with W=1. Reported-by: Rob Herring <robh@kernel.org> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@oracle.com>

2014-07-08ARM: dts: keystone: fix netcp's clocks definitionsGrygorii Strashko1-1/+1
The clocks tree for Keystone 2 NTCP devices should be defined as following: [refclk] - board dependent |- <papllclk> - PLL clock |- <paclk13> - fixed factor clock div=3 mul=1 |- <clkpa> - gated clock |- <clkcpgmac> - gated clock |- <clksa> - gated clock Hence, update Keystone 2 DT to follow HW specification.

2014-02-26ARM: dts: keystone: preparatory patch to support K2L and K2E SOCsMurali Karicheri1-405/+0
Current keystone.dtsi includes SoC specific definitions for K2HK SoCs. In order to support two addition keystone devices, k2 Edison and K2 Lamarr and corresponding EVMs, This patch restructure the dts files for the following:- - All clock nodes that are only available in k2hk SoC are moved from keystone-clocks.dtsi to a new k2hk-clocks.dtsi include file - The CPU nodes are now part of the soc specific k2hk.dtsi. - Change the compatibility string to ti,k2hk-evm and change the model name accordingly - Finally include k2hk-clocks.dtsi in k2hk.dtsi and that in k2hk-evm.dts Cc: Olof Johansson <olof@lixom.net> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Rob Herring <robh+dt@kernel.org> Cc: Kumar Gala <galak@codeaurora.org> Cc: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

2014-02-18ARM: dts: keystone: drop msmcsram clock nodeIvan Khoronzhuk1-10/+0
At late init all unused clocks are disabled. So clocks that were not get before will be gated. In Keysone 2 SoC we have at least one necessary clock that is not used by any driver - "msmcsram". This clock is necessary, because it supplies the Multicore Shared Memory Controller (MSMC). MSMC is the coherency interconnect and all the coherent masters are connected to it including devices which are not under Linux OS control. MSMC clock should not be touched even in low power states. So drop the clock node, otherwise 'clk_ignore_unused' parameter will disable the clock leading to system stall.

2013-12-13ARM: keystone: dts: add a k2hk-evm specific dts fileMurali Karicheri1-17/+6
This patch adds K2 Kepler/Hawking evm (k2hk-evm) specific dts file. To enable re-use of bindings across multiple evms of this family, rename current keystone.dts to keystone.dtsi and include it in the evm specific dts file. K2 SoC has separate ref clock inputs for various clocks. So add separate ref clock nodes for ARM, DDR3A, DDR3B and PA PLL input clocks in k2hk-evm.dts. While at it, rename refclkmain to refclksys based on device User Guide naming convention Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
