Merge tag 'omap-for-v3.13/fixes-against-rc1-take2' of 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>

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. This fix has no impact on the I2C bus frequency.

Some features can be configured by the companion I2C chips, which may not be available at the probe time. Fix the issue by returning -EPROBE_DEFER when the MMC controller slots are not configured. While at it, let's also add minimal device tree support so omap24xx platforms can use this driver without legacy mode since we claim to support device tree for mach-omap2 based systems. Although adding the minimal device tree support is not strictly a fix, it does remove one of the last blockers for dropping a bunch of legacy platform data for mach-omap2.

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.

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.

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.

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.

This patch implements the power_down_finish() method for TC2, to enable the kernel to confirm when CPUs are safely powered down. The information required for determining when a CPU is parked cannot be obtained from any single place, so a few sources of information must be combined: * mcpm_cpu_power_down() must be pending for the CPU, so that we don't get confused by false STANDBYWFI positives arising from CPUidle. This is detected by waiting for the tc2_pm use count for the target CPU to reach 0. * Either the SPC must report that the CPU has asserted STANDBYWFI, or the TC2 tile's reset control logic must be holding the CPU in reset. Just checking for STANDBYWFI is not sufficient, because this signal is not latched when the the cluster is clamped off and powered down: the relevant status bits just drop to zero. This means that STANDBYWFI status cannot be used for reliable detection of the last CPU in a cluster reaching WFI. This patch is required in order for kexec to work with MCPM on TC2. MCPM code was changed in commit 0de0d646 ('ARM: 7848/1: mcpm: Implement cpu_kill() to synchronise on powerdown'), and since then it will hit a WARN_ON_ONCE() due to power_down_finish not being implemented on the TC2 platform.

However, while most of the boards were properly adjusted accordingly, the Armada 370 DB board was left unchanged, and therefore, PCIe is seen as not enabled on this board.

The Armada XP provides a mechanism called "virtual CPU registers" or "per-CPU register banking", to access the per-CPU registers of the current CPU, without having to worry about finding on which CPU we're running. CPU0 has its registers at 0x21800, CPU1 at 0x21900, CPU2 at 0x21A00 and CPU3 at 0x21B00. The virtual registers accessing the current CPU registers are at 0x21000. However, in the Device Tree node that provides the register addresses for the coherency unit (which is responsible for ensuring coherency between processors, and I/O coherency between processors and the DMA-capable devices), a mistake was made: the CPU0-specific registers were specified instead of the virtual CPU registers. This means that the coherency barrier needed for I/O coherency was not behaving properly when executed from a CPU different from CPU0. This patch fixes that by using the virtual CPU registers.
