bus: ti-sysc: Add mcasp optional clocks flag

2020-01-27T13:50:02Z

[ Upstream commit 2c63a833e4500b341a62bf97e67488909ae12086 ] We have OPT_CLKS_NEEDED in legacy platform data, but it's missing from the ti-sysc driver for device tree based configuration. In order to pass OPT_CLKS_NEEDED quirk flag we need to update omap4 module data and add a new compatible for dra7 as the module layout is different from sysc_regbits_omap4_mcasp.

Allwinner drivers changes for 4.19 There's been work for this release cycles in both the SRAM controller driver in order to support more SoCs, as part of our VPU work, but also to enable the EMAC on the A64 (that needs to poke at registers within the same register space). Some work has been needed too to represent the bus to the display engine controllers that all need an SRAM to be mapped to the CPU to be able to access those controllers' registers. * tag 'sunxi-drivers-for-4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: soc: sunxi: Add the A13, A23 and H3 system control compatibles drivers: soc: sunxi: Add support for the C1 SRAM region dt-bindings: sram: sunxi: Populate valid sections compatibles dt-bindings: sram: sunxi: Add A13, A20, A23 and H3 dedicated bindings soc: sunxi: sram: Add dt match for the A10 system-control compatible dt-bindings: sram: sunxi: Introduce new A10 binding for system-control bus: add bus driver for accessing Allwinner A64 DE2 dt-bindings: add binding for the Allwinner A64 DE2 bus soc: sunxi: sram: Add updated compatible string for A64 system control dt-bindings: sram: Rename A64 SRAM controller compatible soc: sunxi: export a regmap for EMAC clock reg on A64 Signed-off-by: Olof Johansson

dt-bindings: remove 'interrupt-parent' from bindings

2018-07-25T20:09:39Z

'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

bus: ti-sysc: Add support for using ti-sysc for MCAN on dra76x

The dra76x MCAN generic interconnect module has a its own format for the bits in the control registers. Therefore add a new module type, new regbits and new capabilities specific to the MCAN module. Acked-by: Rob Herring CC: Tony Lindgren Signed-off-by: Faiz Abbas Signed-off-by: Tony Lindgren

dt-bindings: add binding for the Allwinner A64 DE2 bus

bus: ti-sysc: Add handling for clkctrl opt clocks

2018-04-30T19:04:51Z

There can be up to eight optional device functional gate gate clocks for each clkctrl instance in clkctrl register bits 8 to 15. Some of them are only needed for module level reset while others may always be needed during use. Let's add support for those and update the binding doc accordingly. Note that the optional clkctrl mux and divider clocks starting at bit 20 can be directly mapped to the child devices, and ti-sysc does not need to manage those. And as GPIOs need the optional clocks for reset, we can now add it with SYSC_QUIRK_OPT_CLKS_IN_RESET.

Fix devicetree binding examples for the Generic Memory Interface (GMI) bus driver found on Tegra SOCs.

ARM: dts: Add generic ti,sysc compatible in addition to the custom ones

2017-12-21T15:28:54Z

Otherwise we cannot use generic OF_DEV_AUXDATA match without listing all the compatibles separately for OF_DEV_AUXDATA. Let's also update the binding accordingly. Let's also fix omap4.dtsi to use "ti,sysc-omap4-sr" compatible as we have documented in the binding. This was not noticed earlier as we're still probing SmartReflex driver with platform data.

dt-bindings: ti-sysc: Update binding for timers and capabilities

2017-12-15T17:39:11Z

The ti-sysc binding does not yet describe the capabilities of the interconnect target module. So to make the ti-sysc binding usable for configuring the interconnect target module, we need to add few more properties: 1. To detect between omap2 and omap4 timers, let's add compatibles for them for "ti,sysc-omap2-timer" and,sysc-omap4-timer". This makes it easier to pick up the already initialized system timers later on 2. Let's add "ti,sysc-mask" for a mask of features supported by the interconnect target module. This describes what we have available in the various SYSCONFIG registers 3. Let's add "ti,sysc-midle" and "ti,sysc-sidle" lists for the master and slave idle modes supported by the interconnect target module. These describe the values available for MIDLE and SIDLE bits in the SYSCONFIG registers 4. Some interconnect target modules need a short delay after reset before they can be accessed, let's use "ti,sysc-delay-us" for that 5. Let's add "ti,syss-mask" bit to describe the optional SYSSTATUS register bits for reset done bits 6. Let's support the two existing custom quirk properties already listed in Documentation/devicetree/bindings/arm/omap/omap.txt for "ti,no-reset-on-init" and "ti,no-idle-on-init" 7. And finally, let's add a header for the binding for the dts files and the driver to use Cc: Benoît Cousson Cc: Dave Gerlach Cc: Laurent Pinchart Cc: Liam Girdwood Cc: Mark Brown Cc: Mark Rutland Cc: Mauro Carvalho Chehab Cc: Nishanth Menon Cc: Matthijs van Duin Cc: Paul Walmsley Cc: Peter Ujfalusi Cc: Sakari Ailus Cc: Suman Anna Cc: Tero Kristo Cc: Tomi Valkeinen Reviewed-by: Rob Herring Signed-off-by: Tony Lindgren
