* ARM: dts: am437x-idk-evm: Disable OPP50 for MPUDave Gerlach2017-12-211-0/+14
| | | | | | | | | | | AM437x IDK has a TPS386000 supply voltage supervisor on the VDD_MPU rail set to trigger undervoltage condition at 0.96V. Because of this, OPP50, which is normally configured to 300MHz at 0.95V, must be disabled to avoid triggering the undervoltage condition. Also mark OPP100 as the suspend-opp as it is now our lowest OPP. Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | | Due to a mistake in documentation the DS0_PULL_UP_DOWN_EN macro was mistakenly defined as an active high bit, however setting the bit actually disables the internal pull resistor on the pin, so correct this macro and introduce a new DS0_PULL_UP_DOWN_DIS macro with the proper bit value set now that the documentation has been updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: $ find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec \ sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" \ -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C For simplicity, two sed expressions were used to solve each warnings separately.

| | * ARM: dts: Fix omap4 hang with GPS connected to USB by using wakeupgenTony Lindgren2017-11-281-2/+0

This issue happens in cpuidle states C2 and C3 and does not happen if cpuidle is limited to C1 state only. The symptoms are that the whole system hangs and never wakes up from idle, and if a watchdog is configured the system reboots after a while. Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC interrupt controller directly as a parent instead of the WUGEN. We need to pass the interrupts through WUGEN to GIC to provide the wakeup events for the processor. Let's fix the issue by removing the gic interrupt-parent and use the default interrupt-parent wakeupgen instead. Note that omap5.dtsi had this already fixes earlier by commit 7136d457f365 ("ARM: omap: convert wakeupgen to stacked domains") but we somehow missed omap4 at that point.

They are marked read-only in a software bit (L_PMD_SECT_RDONLY) but the hardware read-only bit is not set (PMD_SECT_AP2). For user mappings, the logic that propagates the software bit to the hardware bit is in set_pmd_at(); but for the kernel, section_update() writes the PMDs directly, skipping this logic. The fix is to set PMD_SECT_AP2 for read-only sections in section_update(), at the same time as L_PMD_SECT_RDONLY.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Noticed with a Clang build. This improves the readability of the ?: expression, as it has lower precedence than the - expression. Show explicitly that - is evaluated first.

Only the PCI/MSI part of it does, and there is no reason not to blow away most of the irqchip stack because PCI is not selected (though not selecting PCI seem to be asking for punishment, but hey...). So let's split the PCI-specific part from the ITS in the Kconfig file, and let's make that part depend on PCI. Architecture specific hacks (arch/arm{,64}/Kconfig) will be addressed in a separate patch. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
