* ARM: dts: am335x: fix cd-gpios definition as per hardware design and dt ↵Mugunthan V N2015-10-133-4/+3
| | | | | | | | | | | | | | | binding docs As per mmc device tree binding documentation card detect gpio has to be active low signal. When a hardware is designed with active high card detect, gpio polarity has to be changed with cd-inverted dt property. In AM335x the card detect gpio is designed as active low gpio. So correcting the dt card detect gpio definition. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: dts: omap3-lilly-a83x: Don't use IRQ level flag for a GPIOJavier Martinez Canillas2015-10-131-1/+1
| | | | | | | | | The card detect GPIO is using IRQ_TYPE_LEVEL_LOW in the GPIO flag cells but this defined constant is meant to be used for a IRQ and not a GPIO. So instead use GPIO_ACTIVE_LOW that seems to be the original intention. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: dts: DRA74x: Add IOMMU nodes for DSP2Suman Anna2015-10-131-0/+20
| | | | | | | | | | | The DRA74x family of SoCs have a second DSP, that also has two MMUs just like the DSP1 subsystem. Add the IOMMU nodes for this DSP2 subsystem in disabled state to the DRA74x specific DTS file, the nodes would need to be enabled appropriately in the respective board DTS files.

* ARM: dts: DRA7: Add common IOMMU nodesSuman Anna2015-10-131-0/+40
| | | | | | | | | | | | | | | | | | The DRA7xx family of SOCs have two IPUs and one DSP processor subsystems in common. The IOMMU DT nodes have been added for these processor subsystems, and have been disabled by default. These MMUs are very similar to those on OMAP4 and OMAP5, with the only difference being the presence of a second MMU within the DSP subsystem for the EDMA port. The DSP IOMMUs also need an additional 'ti,syscon-mmuconfig' property compared to the IPU IOMMUs. NOTE: The enabling of these nodes is left to the respective board dts files.

* ARM: dts: DRA74x: Add dsp2_system syscon nodeSuman Anna2015-10-131-0/+5
| | | | | | | | | | | | | | | | | | | The DSP_SYSTEM sub-module is a dedicated system control logic module present within a DRA7 DSP processor sub-system. This module is responsible for power management, clock generation and connection to the device PRCM module. Add a syscon node for this module for the DSP2 processor sub-system. This is added as a syscon node as it is a common configuration module that can be used by the different IOMMU instances and the corresponding remoteproc device. The node is added to the dra74x.dtsi file, as the DSP2 processor subsystem is usually present only on the DRA74x variants of the DRA7 SoC family.

| | | | | | | | | | | | | | | | | | | | | Add the sub-mailbox nodes that are used to communicate between MPU and the remote processors IPU1, IPU2 and DSP1. These match the respective node definitions on DRA74x to maintain compatibility for the equivalent remote processors. There is no DSP2 on DRA72x, and so the corresponding sub-mailbox node is not added. These sub-mailbox nodes are added to match the hard-coded mailbox configuration used within the TI IPC 3.x software package. The Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to be running in SMP-mode, and hence only a single sub-mailbox node is added for each. All these sub-mailbox nodes are left in disabled state, and should be enabled (and modified if needed) as per the individual product configuration in the corresponding board dts files.

In this case, it happens that if the bootloader used the NAND and set the DFI arbitration bit, the next access to a static memory controller area, such as an ethernet card, the system bus will stall, and the core will be stalled forever. Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit will be enabled the pxa3xx-nand driver on need anyway. The only left requirement is that upon pxa3xx-nand removal, the bit should be cleared before the clock is disabled. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

At least two MMC driver related issues still seems to remain for omap3 legacy booting and omap4 duovero. Note that the dts changes depend on a recent regulator fix, and are based on the regulator commit now in mainline kernel - Enable autoidle for am43xx clocks to prevent clocks from staying always on - Fix i2c5 pinctrl offsets for omap5-uevm - Enable PCA953X as that's needed for HDMI to work on omap5 - Update phy supplies for beagle x15 beta board - Use palmas-usb for on beagle x15 to start using the related driver that recently got merged * tag 'omap-for-v4.3/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: fix omap2+ address translation for pbias ARM: dts: am57xx-beagle-x15: use palmas-usb for USB2 ARM: omap2plus_defconfig: enable GPIO_PCA953X ARM: dts: omap5-uevm.dts: fix i2c5 pinctrl offsets ARM: OMAP2+: AM43XX: Enable autoidle for clks in am43xx_init_late ARM: dts: am57xx-beagle-x15: Update Phy supplies regulator: pbias: program pbias register offset in pbias driver ARM: omap2plus_defconfig: Enable MUSB DMA support ARM: DRA752: Add ID detect for ES2.0 ARM: OMAP3: vc: fix 'or' always true warning ARM: OMAP2+: Fix booting if no timer parent clock is available ARM: OMAP2+: omap-device: fix race deferred probe of omap_hsmmc vs omap_device_late_init Signed-off-by: Olof Johansson <olof@lixom.net>

However, as a result of characterization, it was determined that this posed a risk in extreme load conditions. Hence the PHY rails are split between two different LDOs. Update the related node as a result LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3 LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie NOTE: We break compatibility with pre-production boards with this change since, the PMIC LDO4 is disabled at OTP level. The new configuration is the plan of record and all pre-production boards are supposed to be replaced with the latest boards matching the mentioned configuration. Some very few 10 something boards have been created and stopped production till the latest modifications were done (PMIC USB interrupt, LDO4 etc) - and all of those boards are now getting scrapped.. If there are any (as per tracking information, there should not be any), TI should be contacted to have them replaced.

This can fail if the system is booting on bootloader configured PLL values until the clock framework driver for the PLL is implemented. Let's just WARN instead, this will provide helpful information for anybody bringing up a new SoC what needs to be fixed. This allows to boot dm814x that's still missing the PLL driver.
