2015-09-15drivers: net: cpsw: Add support to drive gpios for ethernet to be functionalMugunthan V N1-0/+9
In DRA72x EVM, by default slave 1 is connected to the onboard phy, but slave 2 pins are also muxed with video input module which is controlled by pcf857x gpio and currently to select slave 0 to connect to phy gpio hogging is used, but with omap2plus_defconfig the pcf857x gpio is built as module. So when using NFS on DRA72x EVM, board doesn't boot as gpio hogging do not set proper gpio state to connect slave 0 to phy as it is built as module and you do not see any errors for not setting gpio and just mentions dhcp reply not got. To solve this issue, introducing "mode-gpios" in DT when gpio based muxing is required. This will throw a warning when gpio get fails and returns probe defer. When gpio-pcf857x module is installed, cpsw probes again and ethernet becomes functional. Verified this on DRA72x with pcf as module and ramdisk.

Add a new _mv88e6xxx_atu_move function to prepare the ATU data register for the move operation. The ports vector will contain the source port and destination port of the Move operation. If the destination port is 0xF, the MAC addresses mapped to the source port are removed for the address database(s). Then add a _mv88e6xxx_atu_remove wrapper to remove the MAC addresses from a VLAN database that are mapped to a given port, when it leaves it.

These Marvell switches have 4 operations to flush or (re)move, all or only non-static MAC addresses, from the entire set of databases or from just a particular one. The value of the EntryState bits will determine if the operation is either a Flush (0x0) or a Move (0xF). When moving entries from one port to another, entries will be removed if the destination port is 0xF. This patch renames these operations for consistency, add a new generic _mv88e6xxx_atu_flush_move function, and change _mv88e6xxx_flush_fid to use it.

2015-09-11drm/qxl: validate monitors config modesJonathon Jongsma2-26/+42
Due to some recent changes in drm_helper_probe_single_connector_modes_merge_bits(), old custom modes were not being pruned properly. In current kernels, drm_mode_validate_basic() is called to sanity-check each mode in the list. If the sanity-check passes, the mode's status gets set to to MODE_OK. In older kernels this check was not done, so old custom modes would still have a status of MODE_UNVERIFIED at this point, and would therefore be pruned later in the function. As a result of this new behavior, the list of modes for a device always includes every custom mode ever configured for the device, with the largest one listed first. Since desktop environments usually choose the first preferred mode when a hotplug event is emitted, this had the result of making it very difficult for the user to reduce the size of the display. The qxl driver did implement the mode_valid connector function, but it was empty. In order to restore the old behavior where old custom modes are pruned, we implement a proper mode_valid function for the qxl driver. This function now checks each mode against the last configured custom mode and the list of standard modes. If the mode doesn't match any of these, its status is set to MODE_BAD so that it will be pruned as expected.

2015-09-10dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}Christoph Hellwig1-6/+0
Since 2009 we have a nice asm-generic header implementing lots of DMA API functions for architectures using struct dma_map_ops, but unfortunately it's still missing a lot of APIs that all architectures still have to duplicate. This series consolidates the remaining functions, although we still need arch opt outs for two of them as a few architectures have very non-standard implementations. This patch (of 5): The coherent DMA allocator works the same over all architectures supporting dma_map operations. This patch consolidates them and converges the minor differences: - the debug_dma helpers are now called from all architectures, including those that were previously missing them - dma_alloc_from_coherent and dma_release_from_coherent are now always called from the generic alloc/free routines instead of the ops dma-mapping-common.h always includes dma-coherent.h to get the defintions for them, or the stubs if the architecture doesn't support this feature - checks for ->alloc / ->free presence are removed. There is only one magic instead of dma_map_ops without them (mic_dma_ops) and that one is x86 only anyway. Besides that only x86 needs special treatment to replace a default devices if none is passed and tweak the gfp_flags. An optional arch hook is provided for that.

2015-09-10kexec: split kexec_load syscall from kexec core codeDave Young2-2/+2
There are two kexec load syscalls, kexec_load another and kexec_file_load. kexec_file_load has been splited as kernel/kexec_file.c. In this patch I split kexec_load syscall code to kernel/kexec.c. And add a new kconfig option KEXEC_CORE, so we can disable kexec_load and use kexec_file_load only, or vice verse. The original requirement is from Ted Ts'o, he want kexec kernel signature being checked with CONFIG_KEXEC_VERIFY_SIG enabled. But kexec-tools use kexec_load syscall can bypass the checking. Vivek Goyal proposed to create a common kconfig option so user can compile in only one syscall for loading kexec kernel. KEXEC/KEXEC_FILE selects KEXEC_CORE so that old config files still work. Because there's general code need CONFIG_KEXEC_CORE, so I updated all the architecture Kconfig with a new option KEXEC_CORE, and let KEXEC selects KEXEC_CORE in arch Kconfig. Also updated general kernel code with to kexec_load syscall. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Dave Young <dyoung@redhat.com> Cc: Eric W.

2015-09-10drm/i915: Don't try to use DDR DVFS on CHV when disabled in the BIOSVille Syrjälä2-13/+31
If one disables DDR DVFS in the BIOS, Punit will apparently ignores all DDR DVFS request. Currently we assume that DDR DVFS is always operational, which leads to errors in dmesg when the DDR DVFS requests time out. Fix the problem by gently prodding Punit during driver load to find out whether it will respond to DDR DVFS requests. If the request times out, we assume that DDR DVFS has been permanenly disabled in the BIOS and no longer perster the Punit about it.

There exist one issue by below case that case system hang: ifconfig eth0 down ifconfig eth0 hw ether 00:10:19:19:81:19 After eth0 down, all fec clocks are gated off. In the .fec_set_mac_address() function, it will set new MAC address to registers, which causes system hang. So it needs to add netif status check to avoid registers access when clocks are gated off. Until eth0 up the new MAC address are wrote into related registers. V2: As Lucas Stach's suggestion, add a comment in the code to explain why it needed.

Current check of phydev with IS_ERR(phydev) may make not much sense because of_phy_connect() returns NULL on failure instead of error value. Still for checking result of phy_connect() IS_ERR() makes perfect sense. So let's use combined check IS_ERR_OR_NULL() that covers both cases.
