2022-05-05ARM: shmobile: Drop commas after dt_compat sentinelsGeert Uytterhoeven1-1/+1
It does not make sense to have a comma after a sentinel, as any new elements must be added before the sentinel. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/ab4acc22eebb96a0747eb301c878b24b1200736a.1646311825.git.geert+renesas@glider.be

There is no reason to keep on using the __raw_{read,write}l() I/O accessors in Renesas ARM platform code. Switch to using the plain {read,write}l() I/O accessors, to have a chance that this works on big-endian.

2016-11-02ARM: shmobile: r8a7778: Stop passing mode pins state to clock driverGeert Uytterhoeven1-15/+0
Now the R-Car M1A CPG clock driver obtains the state of the mode pins from the R-Car RST driver, there's no longer a need to pass this state explicitly. Hence we can just remove the .init_time() callback, the generic ARM code will take care of calling of_clk_init().

This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq domain."), Bock-W legacy hangs during boot with: Unable to handle kernel paging request at virtual address cf86a128 pgd = c0004000 [cf86a128] *pgd=6f80041e(bad) Internal error: Oops: 8000000d [#1] SMP ARM CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.19.0-rc4 #1 Hardware name: bockw task: cf823b40 ti: cf824000 task.ti: cf824000 PC is at 0xcf86a128 LR is at request_threaded_irq+0xbc/0x124 This happens because the IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the platform board code. To fix this, instantiate the GIC from platform board code when compiling a legacy kernel, like is done for the sh73a0 and r8a7740 legacy code.

The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: - AMLogic Meson8 - ARM Realview in DT mode - Allwinner A80 - Broadcom BCM47081 - Broadcom Cygnus - Freescale LS1021A - Freescale Vybrid 500 series - Mediatek MT6592, MT8127, MT8135 - STMicroelectronics STiH410 - Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete. As usual, these get extended over time.

Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support.

2013-12-24ARM: shmobile: r8a7778: Don't define SCIF platform data in an arrayLaurent Pinchart1-17/+19
The SCIF driver is transitioning to platform resources. Board code will thus need to define an array of resources for each SCIF device. This is incompatible with the macro-based SCIF platform data definition as an array. Rework the macro to define platform data as individual structures.

Pull ARM SoC platform changes from Olof Johansson: "New and updated SoC support. Among the things new for this release are: - More support for the AM33xx platforms from TI - Tegra 124 support, and some updates to older tegra families as well - imx cleanups and updates across the board - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM, and turned out to be too broad a name. New name is ARCH_BCM_MOBILE. - A whole bunch of updates and fixes for integrator, making the platform code more modern and switches over to DT-only booting. - Support for two new Renesas shmobile chipsets. Next up for them is more work on consolidation instead of introduction of new non-multiplatform SoCs, we're all looking forward to that! - Misc cleanups for older Samsung platforms, some Allwinner updates, etc" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (159 commits) ARM: bcm281xx: Add ARCH_BCM_MOBILE to bcm config ARM: bcm_defconfig: Run "make savedefconfig" ARM: bcm281xx: Add ARCH Timers to config rename ARCH_BCM to ARCH_BCM_MOBILE (mach-bcm) ARM: vexpress: Enable platform-specific options in defconfig ARM: vexpress: Make defconfig work again ARM: sunxi: remove .init_time hooks ARM: imx: enable suspend for imx6sl ARM: imx: ensure dsm_request signal is not asserted when setting LPM ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter() ARM: imx6q: move low-power code out of clock driver ARM: imx: drop extern with function prototypes in common.h ARM: imx: reset core along with enable/disable operation ARM: imx: do not return from imx_cpu_die() call ARM: imx_v6_v7_defconfig: Select CONFIG_PROVE_LOCKING ARM: imx_v6_v7_defconfig: Enable LEDS_GPIO related options ARM: mxs_defconfig: Turn off CONFIG_DEBUG_GPIO ARM: imx: replace imx6q_restart() with mxc_restart() ARM: mach-imx: mm-imx5: Retrieve iomuxc base address from dt ARM: mach-imx: mm-imx5: Retrieve tzic base address from dt ...
2013-10-08ARM: shmobile: r8a7778: split r8a7778_init_irq_extpin() for DTKuninori Morimoto1-1/+5
r8a7778 INTC needs IRL pin mode settings to determine behavior of IRQ0 - IRQ3, and r8a7778_init_irq_extpin() is controlling it via irlm parameter. But this function registers renesas_intc_irqpin driver if irlm was set, and this value depends on platform. This is not good for DT. This patch splits r8a7778_init_irq_extpin() function into "mode settings" and "funtion register" parts.
