git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "Another batch of fixes for ARM SoCs for 3.13. The diffstat is large, mostly because of: - Another set of fixes to fix regressions caused by moving OMAP from board files to DT. Tony thinks this was the last major set of fixes, with maybe just a few small patches to follow. - More fixes for Marvell platforms, most dealing with misdescribed PCIe hardware, i.e. incorrect number of busses on some SoCs, etc. The line delta adds up due to various ranges moving around when this is fixed. But there's also: - Some smaller tweaks to defconfigs to make more boards bootable in my test setup for better coverage. - There are also a few other smaller fixes, a short series for at91, a couple of reverts for ux500, etc" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) arm: dts: socfpga: Change some clocks of gate-clk type to perip-clk arm: socfpga: Enable ARM_TWD for socfpga ARM: multi_v7_defconfig: enable SDHCI_BCM_KONA and MMC_BLOCK_MINORS=16 ARM: sunxi_defconfig: enable NFS, TMPFS, PRINTK_TIME and nfsroot support ARM: multi_v7_defconfig: enable network for BeagleBone Black ARM: dts: Fix the name of supplies for smsc911x shared by OMAP ARM: OMAP2+: Powerdomain: Fix unchecked dereference of arch_pwrdm ARM: dts: omap3-beagle: Add omap-twl4030 audio support ARM: dts: omap4-sdp: Fix pin muxing for wl12xx ARM: dts: omap4-panda-common: Fix pin muxing for wl12xx ARM: at91: fixed unresolved symbol "at91_pm_set_standby" when built without CONFIG_PM ARM: at91: add usart3 alias to dtsi ARM: at91: sama5d3: reduce TWI internal clock frequency mmc: omap: Fix I2C dependency and make driver usable with device tree mmc: omap: Fix DMA configuration to not rely on device id ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13) ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi ARM: dts: AM33XX IGEP0033: add USB support ARM: dts: AM33XX BASE0033: add 32KBit EEPROM support ARM: dts: AM33XX BASE0033: add pinmux and user led support ...

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes From Tony Lindgren: Some omap related fixes that have come up with people moving to device tree only based booting for omap2+. The series contains a handful of fixes for the igep boards as they were one of the first omap3 boards to jump over completely to device tree based booting. So these can be considered regressions compared to booting igep in legacy mode with board files in v3.12. Also included are few other device tree vs legacy booting regressions: - yet more missing omap3 .dtsi entries that have showed up booting various boards with device tree only - n900 eMMC device tree fix - fixes for beagle USB EHCI - two fixes to make omap2420 MMC work As we're moving omap2+ to be device tree only for v3.14, I'd like to have v3.13 work equally well for legacy based booting and device tree based booting. So there will be likely few more device tree related booting patches trickling in. This series also includes a regression fix for the omap timer posted mode that may wrongly stay on from the bootloader for some SoCs. * tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: mmc: omap: Fix I2C dependency and make driver usable with device tree mmc: omap: Fix DMA configuration to not rely on device id ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13) ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi ARM: dts: AM33XX IGEP0033: add USB support ARM: dts: AM33XX BASE0033: add 32KBit EEPROM support ARM: dts: AM33XX BASE0033: add pinmux and user led support ARM: dts: AM33XX BASE0033: add pinmux and hdmi node to enable display ARM: dts: omap3-igep0020: Add pinmuxing for DVI output ARM: dts: omap3-igep0020: Add pinmux setup for i2c devices ARM: dts: omap3-igep: Update to use the TI AM/DM37x processor ARM: dts: omap3-igep: Add support for LBEE1USJYC WiFi connected to SDIO ARM: dts: omap3-igep: Fix bus-width for mmc1 ARM: OMAP2+: dss-common: change IGEP's DVI DDC i2c bus ARM: OMAP2+: Disable POSTED mode for errata i103 and i767 ARM: OMAP2+: Fix eMMC on n900 with device tree ARM: OMAP2+: Add fixed regulator to omap2plus_defconfig ARM: OMAP2+: Fix more missing data for omap3.dtsi file Signed-off-by: Olof Johansson <olof@lixom.net>

drivers/net/ethernet/smsc/smsc911x.c is expecting supplies named "vdd33a" and "vddvario". Currently the shared DTS file provides "vmmc" and "vmmc_aux", and the supply lookup will fail: smsc911x 2c000000.ethernet: Looking up vdd33a-supply from device tree smsc911x 2c000000.ethernet: Looking up vdd33a-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed smsc911x 2c000000.ethernet: Looking up vddvario-supply from device tree smsc911x 2c000000.ethernet: Looking up vddvario-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed Fix it! Looks like commmit 6b2978ac40e4 (ARM: dts: Shared file for omap GPMC connected smsc911x) made the problem more visible by moving the smc911x configuration from the omap3-igep0020.dts file to the generic file.

This fixes WLAN on omap4-sdp that got broken in v3.10 when we moved omap4 to boot using device tree only as I did not have the WL12XX card in my omap4 SDP to test with.

2013-12-02ARM: dts: omap4-panda-common: Fix pin muxing for wl12xxBalaji T K
pin mux wl12xx_gpio and wl12xx_pins should be part of omap4_pmx_core and not omap4_pmx_wkup. So, move wl12xx_* to omap4_pmx_core. Fix the following error message: pinctrl-single 4a31e040.pinmux: mux offset out of range: 0x38 (0x38) pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x SDIO card is not detected after moving pin mux to omap4_pmx_core since sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card. This fixes a regression where WLAN did not work after a warm reset or after one up/down cycle that happened when we move omap4 to boot using device tree only.

2013-12-02ARM: at91: sama5d3: reduce TWI internal clock frequencyLudovic Desroches
With some devices, transfer hangs during I2C frame transmission. This issue disappears when reducing the internal frequency of the TWI IP. Even if it is indicated that internal clock max frequency is 66MHz, it seems we have oversampling on I2C signals making TWI believe that a transfer in progress is done.

2013-11-26ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13)Roger Quadros
Beagle (rev. C4) and Beagle-XM (all revs) need VAUX2 1.8V supply for the USB PHY. As the generic PHY driver can't handle more than one supply at the moment, we configure this supply to be always on. This will cause a very small power impact if the USB host subsystem is not in use, about 76.86 micro-W + LDO power. Older Beagle boards (prior to C4) don't have VAUX2 connected anywhere, so there won't be any functional impact on those boards other than some additional LDO power consumption.

2013-11-26ARM: dts: omap3-igep: Update to use the TI AM/DM37x processorEnric Balletbo i Serra
Most of the boards are using the TI AM/DM37x processor, there is only a small quantity of IGEP Processor Boards based on TI OMAP3530. So it's better use the omap36xx.dtsi include instead of omap34xx.dtsi include. We can add support for the 34xx based variant later on as needed. To avoid confusion we have added to the model the (TI AM/DM37x) comment.

2013-11-26ARM: OMAP2+: dss-common: change IGEP's DVI DDC i2c busJavier Martinez Canillas
IGEP's DVI connector's DDC pins are connected to OMAP's third i2c bus. When booting with Device Trees the requested bus number is set to -1 which means that the bus number should be dynamically assigned. So the third i2c bus has 2 has a bus number. Since now only DT booting is supported for IGEP boards after commit 06ff74fd ("ARM: OMAP2+: remove legacy support for IGEP boards"), the i2c bus number has to be changed.

2013-11-26ARM: OMAP2+: Disable POSTED mode for errata i103 and i767Joel Fernandes
Enabling of Posted mode is seen to cause problems on dmtimer modules on AM33xx (much like other OMAPs). Reference discussions on forums [1] [2]. Earlier patch solving this on other OMAPs [3]. For OMAP SoCs with this errata, the fix has been to not enable Posted mode. However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode is enabled on reset. So we not only need to ignore enabling of the POSTED bit when the timer is requested, but also disable Posted mode if errata is present.
