Merge tag 'imx-soc-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc i.MX SoC changes for 4.12: - A correction on mmdc_pmu_write_accesses event definition. - Add new axi_id perf command to support MMDC filter memory usage profiling. - Set correct SPI chip_select in platform device registration, so that spi-imx driver code can be improved to use chip_select directly for harwdare setup instead of indirectly via the cs_gpio mapping array. - Disable APIS bus supervisor protect for i.MX25, since the default configuration doesn't work for a few peripherals accessed through SDMA. - Add compatible check for the secondary generation of I2SE i.MX28 Duckbill board support. * tag 'imx-soc-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: mxs: add support for I2SE Duckbill 2 boards ARM: i.MX25: globally disable supervisor protect ARM: imx: set correct chip_select in platform setup ARM: imx: Add AXI address filter support for MMDC profiling ARM: imx: Fix mmdc_pmu_write_accesses event definition Signed-off-by:

The Duckbill devices are small, pen-drive sized boards based on NXP's i.MX28 SoC. While the initial variants (Duckbill series) were equipped with a micro SD card slot only, the latest generation (Duckbill 2 series) have an additional internal eMMC onboard. To distinguish between both generations, a new device tree compatible string was introduced. To get the MAC address fixup applied, we need to check for this new string here, too. Signed-off-by:

The problem described in commit 6befda9a ("ARM: i.MX53: globally disable supervisor protect") for the i.MX53 platform applies to i.MX25 as well. E.g. CSPI1+SDMA and SSI1+SDMA are not working with the default AIPS configuration. Modifiy the AIPS configuration to allow access to the bus by SDMA and peripherals. Signed-off-by:

As already explained for pm_suspend.S, the DDRSDR controller fails to put LPDDR1 memories in self-refresh. Force the controller to think it has DDR2 memories during the self-refresh period, as the DDR2 self-refresh spec is equivalent to LPDDR1, and is correctly implemented in the controller. Acked-by:

Pull "Broadcom soc changes for 4.12" from Florian Fainelli: This pull request contains Broadcom ARM-based SoC Kconfig/platform changes for 4.12, please pull the following: - Al enables ZONE_DMA for BRCMSTB platforms since a bunch of on-chip peripherals such as USB (OHCI and EHCI) and SDHCI cannot support physical addresses > 32-bit. This is only required when ARM_LPAE is enabled - Danesh enables ARCH_HAS_HOLES_MEMORYMODEL in order for the kernel to provide a pfn_valid() implementation despite BRCMSTB enabling the SPARSEMEM model by default. - Florian adds support for a new 28nm generation chip: 7260 by updating the runtime detection UART debuggin stub used for DEBUG_LL. * tag 'arm-soc/for-4.12/soc' of http://github.com/Broadcom/stblinux: ARM: brcmstb: Add entry for 7260 ARM: brcmstb: Enable ARCH_HAS_HOLES_MEMORYMODEL ARM: brcmstb: Enable ZONE_DMA for non 64-bit capable peripherals

Merge tag 'davinci-for-v4.12/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc Pull "DaVinci SoC updates for v4.12" from Sekhar Nori: v4.12 SoC updates for DaVinci include necessary pdata-quirks to make video capture and display work on da850. VPIF driver which supports video capture and display on da850 is a legacy driver. It does not have DT equavalents for all things that are used on platform data. Attempts were made to pass data via DT[1], but linux-media does not yet have a good way of describing subdevices in device tree. This is work in progress. As soon as bindings are defined and implementation is available, we can shift to using that. For now we are stuck with using pdata. The pull request also has some clean-up for PM, and a fix for pdata quirks mechanism.

I found this section mismatch when building with an older compiler release: WARNING: vmlinux.o(.text+0x3051c): Section mismatch in reference from the function omap_init_rng() to the function .init.text:omap_device_build() Obviously this one function should be __init as well.

It seems that if L3_INIT clkdomain is kept in HW_AUTO while usb_otg_ss is in use then there are random chances that the usb_otg_ss module will fail to completely idle. i.e. IDLEST = 0x2 instead of 0x3. Preventing L3_INIT from HW_AUTO while usb_otg_ss module is in use fixes this issue. We don't know yet if usb_otg_ss instances 3 and 4 are affected by this issue or not so don't add this flag for those instances. Cc: Tero Kristo <t-kristo@ti.com> Signed-off-by:

We cannot select the option when SERIAL_8250 is not also set: warning: (ARCH_GEMINI) selects SERIAL_OF_PLATFORM which has unmet direct dependencies (TTY && HAS_IOMEM && SERIAL_8250 && OF) This removes the 'select' statement, requiring that users enable the option manually. Alternatively, we could make it a conditional 'select SERIAL_OF_PLATFORM if SERIAL_8250' or also select a handful of other symbols that it depends on. Signed-off-by:
