ARM: OMAP2+: Drop omap_hwmod_irq_info

2017-10-10T21:27:19+00:00

With the previous patches removing the need for legacy IRQs now that all of mach-omap2 is booting in device tree only mode, we can drop struct omap_hwmod_irq_info. Note that we can now also finally drop omap4_xlate_irq. Cc: Lokesh Vutla Cc: Marc Zyngier Cc: Paul Walmsley Cc: Tero Kristo Signed-off-by: Tony Lindgren

ARM: OMAP4+: Initialize SAR RAM base early for proper CPU1 reset for kexec

2016-06-23T05:55:47+00:00

Prepare things for making kexec work on SMP omap variants by initializing SARM RAM base early. This allows us to configure CPU1 for kexec in case the previous kernel has put CPU1 in low power mode. Note that this should not prevent moving other SAR RAM code to live under drivers. However for kexec, we will need this very early.

ARM: omap2: restore OMAP4 barrier behaviour

2015-07-25T14:28:16+00:00

Restore the OMAP4 barrier behaviour using the new implementation which allows multiplatform systems to hook into the mb() and wmb() ARM implementations to perform any necessary additional barrier maintanence. Acked-by: Tony Lindgren Acked-by: Richard Woodruff Signed-off-by: Russell King

Revert "ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688"

2015-07-25T14:28:14+00:00

This reverts commit 606da4826b89b044b51e3a84958b802204cfe4c7. We actually need this code for proper behaviour of OMAP4, and it needs fixing a different way other than just removing the code. Disabling code which is necessary in the hopes of persuing multiplatform kernels is a stupid approach. Acked-by: Tony Lindgren Acked-by: Richard Woodruff Signed-off-by: Russell King

ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688

2015-03-16T23:23:28+00:00

The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a contradiction in it's dependencies. The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be enabled. These options inherit a dependency from an enclosing menu, that requires ARCH_MULTIPLATFORM to be 'enabled'. This is a contradiction and made this option also unavailable for non-multiplatform configurations. Since there are no selects on OMAP4_ERRATA_I688, which would ignore dependencies, the code related to that option is dead and can be removed. This (logical) defect has been found with the undertaker tool. (https://undertaker.cs.fau.de) Signed-off-by: Stefan Hengelein Acked-by: Santosh Shilimkar Signed-off-by: Tony Lindgren

ARM: omap: convert wakeupgen to stacked domains

2015-03-15T00:56:13+00:00

OMAP4/5 has been (ab)using the gic_arch_extn to provide wakeup from suspend, and it makes a lot of sense to convert this code to use stacked domains instead. This patch does just this, updating the DT files to actually reflect what the HW provides. BIG FAT WARNING: because the DTs were so far lying by not exposing the WUGEN HW block, kernels with this patch applied won't have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs won't even boot. On a platform with this patch applied, the system looks like this: root@bacon-fat:~# cat /proc/interrupts CPU0 CPU1 16: 0 0 WUGEN 37 gp_timer 19: 233799 155916 GIC 27 arch_timer 23: 0 0 WUGEN 9 l3-dbg-irq 24: 1 0 WUGEN 10 l3-app-irq 27: 282 0 WUGEN 13 omap-dma-engine 44: 0 0 4ae10000.gpio 13 DMA 294: 0 0 WUGEN 20 gpmc 297: 506 0 WUGEN 56 48070000.i2c 298: 0 0 WUGEN 57 48072000.i2c 299: 0 0 WUGEN 61 48060000.i2c 300: 0 0 WUGEN 62 4807a000.i2c 301: 8 0 WUGEN 60 4807c000.i2c 308: 2439 0 WUGEN 74 OMAP UART2 312: 362 0 WUGEN 83 mmc2 313: 502 0 WUGEN 86 mmc0 314: 13 0 WUGEN 94 mmc1 350: 0 0 PRCM pinctrl, pinctrl 406: 35155709 0 GIC 109 ehci_hcd:usb1 407: 0 0 WUGEN 7 palmas 409: 0 0 WUGEN 119 twl6040 410: 0 0 twl6040 5 twl6040_irq_ready 411: 0 0 twl6040 0 twl6040_irq_th IPI0: 0 1 CPU wakeup interrupts IPI1: 0 0 Timer broadcast interrupts IPI2: 95334 902334 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 479 648 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 0 0 IRQ work interrupts IPI7: 0 0 completion interrupts Err: 0 Acked-by: Tony Lindgren Signed-off-by: Marc Zyngier Link: https://lkml.kernel.org/r/1426088629-15377-8-git-send-email-marc.zyngier@arm.com Signed-off-by: Jason Cooper

irqchip: crossbar: Convert dra7 crossbar to stacked domains

2015-03-15T00:55:24+00:00

Support for the TI crossbar used on the DRA7 family of chips is implemented as an ugly hack on the side of the GIC. Converting it to stacked domains makes it slightly more palatable, as it results in a cleanup. Unfortunately, as the DT bindings failed to acknowledge the fact that this is actually yet another interrupt controller (the third, actually), we have yet another breakage. Oh well.
