2015-07-06ARM: shmobile: Remove legacy board code for Armadillo-800 EVAGeert Uytterhoeven1-9/+0
The Armadillo-800 EVA board is sufficiently supported by DT-based and board-less R-Mobile A1 (r8a7740) multiplatform kernels, and board staging code. Hence remove the legacy board code to reduce maintenance effort. Lacking areas are: - USB (it doesn't work in legacy, neither), - HDMI (it doesn't work in legacy, neither), - Camera (we don't care), - DMAC/IPMMU (no DT bindings are planned).

2015-03-11ARM: shmobile: R-Car Gen2: Add da9063/da9210 regulator quirkGeert Uytterhoeven1-0/+2
The r8a7790/lager and r8a7791/koelsch development boards have da9063 and da9210 regulators. Both regulators have their interrupt request lines tied to the same interrupt pin (IRQ2) on the SoC. After cold boot or da9063-induced restart, both the da9063 and da9210 seem to assert their interrupt request lines. Hence as soon as one driver requests this irq, it gets stuck in an interrupt storm, as it only manages to deassert its own interrupt request line, and the other driver hasn't installed an interrupt handler yet. To handle this, install a quirk that masks the interrupts in both the da9063 and da9210. This quirk has to run after the i2c master driver has been initialized, but before the i2c slave drivers are initialized. As it depends on i2c, select I2C if one of the affected platforms is enabled in the kernel config. On koelsch, the following happens: - Cold boot or reboot using the da9063 restart handler: IRQ2 is asserted, installing da9063/da9210 regulator quirk ... i2c i2c-6: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0058: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0058: Detected da9063 i2c 6-0058: Masking da9063 interrupt sources i2c 6-0068: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0068: Detected da9210 i2c 6-0068: Masking da9210 interrupt sources i2c 6-0068: IRQ2 is not asserted, removing quirk - Warm boot (reset button): rcar_gen2_regulator_quirk: IRQ2 is not asserted, not installing quirk Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Reviewed-by: Mark Brown <broonie@kernel.org> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort.

2015-01-15ARM: shmobile: R-Mobile: Add DT support for PM domainsGeert Uytterhoeven1-1/+2
Populate the PM domains from DT, and provide support to hook up devices to their respective PM domain. The always-on power area (e.g. C5 on r8a7740) is created as a PM domain without software control, to allow Run-Time management of module clocks for hardware blocks inside this area. Special cases like PM domains containing CPUs, the console device, or Coresight-ETM, are handled by scanning the DT topology. As long as the ARM debug/perf code doesn't use resource management with runtime PM support, the power area containing Coresight-ETM (e.g. D4 on r8a7740) must be kept powered to avoid a crash during resume from s2ram (dbg_cpu_pm_notify() calls reset_ctrl_regs() unconditionally, causing an undefined instruction oops). Initialization is done from core_initcall(), as the "renesas,intc-irqpin" driver uses postcore_initcall().

2014-10-28ARM: shmobile: Select CONFIG_ZONE_DMA when CONFIG_ARM_LPAE is enabledLaurent Pinchart1-0/+1
Most IP cores on ARM Renesas platforms can only address 32 bits of physical memory for DMA. Without CONFIG_ZONE_DMA enabled and with the recent CMA highmem allocation support, the default CMA zone is reserved above the 4GiB limit when LPAE is enabled, resulting in various driver failures. Fix the problem by selecting CONFIG_ZONE_DMA. Other options to investigate in the future would be to either enable IOMMU support or use custom CMA reservations for peripherals not supporting LPAE. While not a strict dependency, the "[PATCH 0/4] Low/high memory CMA reservation fixes" series is also required to fix a different but related CMA allocation problem.

The Kconfig symbol ARCH_HAS_OPP became redundant in v3.16: commit 049d595a4db3 ("PM / OPP: Make OPP invisible to users in Kconfig") removed the only dependency that used it. Setting it had no effect anymore. So commit 78c5e0bb145d ("PM / OPP: Remove ARCH_HAS_OPP") removed it. For some reason that commit did not remove all select statements for that symbol. These statements are now useless. Remove one from shmobile too.
