2020-05-19ARM: dts: Configure system timers for am335xTony Lindgren1-4/+2
We can now init system timers using the dmtimer and 32k counter based on only devicetree data and drivers/clocksource timers. Let's configure the clocksource and clockevent, and drop the old unused platform data. As we're just dropping platform data, and the early platform data init is based on the custom ti,hwmods property, we want to drop both the platform data and ti,hwmods property in a single patch. Since the dmtimer can use both 32k clock and system clock as the source, let's also configure the SoC specific default values. The board specific dts files can reconfigure these with assigned-clocks and assigned-clock-parents as needed.

2020-03-04ARM: dts: AM33xx-l4: Update PRUSS interconnect target-module nodeSuman Anna1-3/+18
The PRU-ICSS present on some AM33xx SoCs has a very unique SYSC register. The IP also uses a hard-reset line, and requires this PRCM reset to be deasserted to be able to access any registers. Update the existing PRUSS interconnect target-module with all the required properties. The PRUSS device itself shall be added as a child node to this interconnect node in the future. PRU-ICSS is not supported on AM3351/AM3352/AM3354 SoCs though in the AM33xx family, so the target module node should be disabled in derivative board files that use any of these SoCs.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/dt Drop legacy platform data for omaps for v5.5 This series of changes continues dropping legacy platform data for omaps. With the proper device tree configuration in place in the dts files for ti-sysc interconnect target module driver, we can drop the related platform data and legacy ti,hwmods custom property. Most of the patches in this series drop platform data and custom dts property one device class and one SoC at time. This way we can easily revert one patch at a time in case of unexpected issues if the fix is not trivial.

This is not strictly a fix, but we still also have the older CONFIG_MFD_TI_LMU options available so this cuts down the confusion for trying to guess which display and which backlight is needed - Recent ti-sysc interconnect target module changes need the gpio module disabled on some boards, but this now needs to happen at the module level, not at the gpio driver level - Recent changes to probe system timers with ti-sysc caused warnings about mismatch in syconfig registers, so let's configure the option for RESET_STATUS as available in the TRMs - Recent changes to probe LCDC with ti-sysc caused warnings about mismatch in sysconfig registers, so let's configure the missing idlemodes for both platform data and dts as documented in TRMs - Since we moved mach-omap2 to probe with device tree, we've been getting voltage controller warnings.

2019-09-25ARM: OMAP2+: Add missing LCDC midlemode for am335xTony Lindgren1-1/+3
TRM "Table 13-34. SYSCONFIG Register Field Descriptions" lists both standbymode and idlemode that should be just the sidle and midle registers where midle is currently unconfigured for lcdc_sysc. As the dts data has been generated based on lcdc_sysc, we now have an empty "ti,sysc-midle" property. And so we currently get a warning for lcdc because of a difference with dts provided configuration compared to the legacy platform data. This is because lcdc has SYSC_HAS_MIDLEMODE configured in the platform data without configuring the modes. Let's fix the issue by adding the missing midlemode to lcdc_sysc, and configuring the "ti,sysc-midle" property based on the TRM values.

In general we can do this by dropping legacy "ti,hwmods" custom dts property, and the platform data assuming the related dts data is correct. This is best done as single patch as otherwise we'd have to revert two patches in case of any unexpected issues, and we're just removing data. Fro cpsw, before we can do this, we need to configure the cpsw mdio clocks properly in dts though in the first patch. For omap4 i2c, we've already dropped the platform data earlier, but have been still allocting it dynamically based on the dts data based on the "ti,hwmods" property, but that is no longer needed. For d2d, we are missing the dts data, so we first add it and then drop the platform data. For dra7, we drop platform data and "ti,hwmods" for mcasp and mcspi.

2019-08-26ARM: dts: Add fck for cpsw mdio for omap variantsTony Lindgren1-0/+2
In preparation for dropping legacy platform data and custom ti,hwmods property, we need to make functional clock available for mdio for the SoCs so the the mdio driver can find it. The mdio hardware currently relies on a mdio_hwmod to manage the clock for omap variants. This is wrong though as there are no separate sysconfig registers for mdio. All the cpsw related components are just children of the gmac module. Note that since mdio is a child of cpsw, just doing pm_runtime_get() in the mdio driver enables the clock. However, since mdio is also used by davinci that does not implement runtime PM, let's just add the fck for now. Also note that am437x mdio already has a clock, let's update it to not use the legacy clock naming to unify things further.

2019-05-02bus: ti-sysc: Handle devices with no control registersTony Lindgren1-4/+0
Some interconnect target modules have no module control registers at all, such as d_can on am335x and am437x. The d_can register offset at 0 is CTL register with 0x401 as the default value. I guess I mistook the 0x401 value for a revision register as the value happens to look similar to what the revision registers typically have for other modules. To handle modules with no control registers, we need to improve the ti-sysc driver a bit to bail out with errors on no control registers, and then we can remove the bogus revision registers for d_can.

2019-05-01ARM: dts: Configure osc clock for d_can on am335xTony Lindgren1-4/+6
Reading the module revision register can cause an external abort on non-linefetch depending of osc clock is not already enabled. This started happening with commit 1a5cd7c23cc5 ("bus: ti-sysc: Enable all clocks directly during init to read revision") as reported by Sebastian Andrzej Siewior <bigeasy@linutronix.de>. The reason why the issue happens is because we now attempt to read the interconnect target module revision register by first manually enabling all the device clocks in sysc_probe(). And looks like d_can also needs the osc clock in addition to the module clock, and it may or may not be enabled depending on the bootloader version and if other devices have already requested osc clock. Let's fix the issue by adding osc clock as an optional clock for the module for am335x. Note that am437x does not seem to list the osc clock at all, so presumably it is not needed for am437x. I also noticed that we're incorrectly assuming the revision register for d_can exists. But the module does not seem to have any revision, sysconfig or sysstatus registers. But that's mostly a cosmetic issues, so I'll send a patch separately for that.

Looks like I missed the ranges for am335x epwmss. Let's set it up the same way as for am437x and dra7. Fixes: 87fc89ced3a7 ("ARM: dts: am335x: Move l4 child devices to probe them with ti-sysc") Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2018-12-07ARM: dts: Add am335x mcasp with l3 data port rangesTony Lindgren1-6/+36
Earlier attempt to move am335x mcasp to probe with ti-sysc interconnect target module caused audio to stop working and and the dts changes were reverted by commit 5d2632a577ba ("ARM: dts: Revert am335x mcasp ti-sysc changes"). Turns out we were missing the l3 data port ranges for mcasp. This caused mcasp dma to attempt to use wrong port address. So let's try again essentially reverting the earlier revert and adding the missing l3 data port ranges.

Without this McASP FIFO would constantly underflow. EDMA test via dmatest works though. Let's revert the change for now until we know the root cause. Reported-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2018-10-18ARM: dts: am335x: Move l4 child devices to probe them with ti-syscTony Lindgren1-12/+601
With l4 interconnect hierarchy and ti-sysc interconnect target module data in place, we can simply move all the related child devices to their proper location and enable probing using ti-sysc. In general the first child device address range starts at range 0 from the ti-sysc interconnect target so the move involves adjusting the child device reg properties for that. In case of any regressions, problem devices can be reverted to probe with legacy platform data as needed by moving them back and removing the related interconnect target module node. Note that we are not yet moving dss or wkup_m3, those will be moved later after some related driver changes.

2018-10-18ARM: dts: am335x: Add l4 interconnect hierarchy and ti-sysc dataTony Lindgren1-0/+1543
Similar to commit 8f42cb7f64c7 ("ARM: dts: omap4: Add l4 interconnect hierarchy and ti-sysc data"), let's add proper interconnect hierarchy for l4 interconnect instances with the related ti-sysc interconnect module data as in Documentation/devicetree/bindings/bus/ti-sysc.txt. Using ti-sysc driver binding allows us to start dropping legacy platform data in arch/arm/mach-omap2/omap*hwmod*data.c files later on in favor of ti-sysc dts data. This data is generated based on platform data from a booted system and the interconnect acces protection registers for ranges. To avoid regressions, we initially validate the device tree provided data against the existing platform data on boot. Note that we cannot yet include this file from the SoC dtsi file until the child devices are moved to their proper locations in the interconnect hierarchy in the following patch. Otherwise we would have the each module probed twice.
