2014-05-27usb: host: ehci-exynos: Use devm_ioremap_resource instead of devm_ioremapVivek Gautam
Using devm_ioremap_resource() API should actually be preferred over devm_ioremap(), since the former request the mem region first and then gives back the ioremap'ed memory pointer. devm_ioremap_resource() calls request_mem_region(), therby preventing other drivers to make any overlapping call to the same region.

2014-05-27drivers: Remove duplicate conditionally included subdirsGeert Uytterhoeven
The "macintosh" and "nfs" subdirectories are already traversed unconditionally, so there's no need to keep the conditional entries. The unconditional "macintosh" entry used to depend on CONFIG_PPC_PMAC, but the dependency was dropped in commit 45941d0481f538324fa21d6450116d13f6e51e91 ("[PATCH] enable mouse button 2+3 emulation for x86 macs"), forgetting the second entry for CONFIG_MAC. The two "nfc" entries were introduced by two separate commits: commit 0329326e85aaa30fb8d427828c718d565c287385 ("NFC: Driver for NXP Semiconductors PN544 NFC chip."), and commit 3e256b8f8dfa309a80b5dece388d85d9a9801a29 ("NFC: add nfc subsystem core").

2014-05-27init.h: Update initcall_sync variants to fix build errorsTony Lindgren
We are getting randconfig build errors on device drivers with tristate Kconfig option if they are using custom initcall levels. Rather than add ifdeffery into the drivers, let's add the missing initcall_sync variants. As the comment in init.h has kept people from updating the list of initcalls that can be just module_init when the driver is loaded as a loadable module, let's also update the comment a bit to describe valid use cases custom initcall levels. While most drivers should nowadays use just regular module_init because of the deferred probe, we do have quite a few custom initcall levels left that we cannot remove until tested properly. There are also still few valid cases where a custom initcall level might make sense that I'm aware of. For example a bus snooping driver can provide information about invalid bus access and is handy loader early when built in. But there's no hard dependency to have it necessarily built in and a loadable module is a valid option. Another example is a driver implementing a Linux framework like pinctrl framework. That driver may be needed early on some platforms because of legacy reasons, while it can be just a regular module_init on most platforms.

Adds pinmux and DT node for Micron (MT29F4G08AB) x8 NAND device present on am437x-gp-evm board. (1) As NAND Flash data lines are muxed with eMMC, Thus at a given time either eMMC or NAND can be enabled. Selection between eMMC and NAND is controlled: (a) By dynamically driving following GPIO pin from software SPI2_CS0(GPIO) == 0 NAND is selected (default) SPI2_CS0(GPIO) == 1 eMMC is selected (b) By statically using Jumper (J89) on the board (2) As NAND device connnected to this board has page-size=4K and oob-size=224, So ROM code expects boot-loaders to be flashed in BCH16 ECC scheme for NAND boot.

2014-05-27PCI: Test for std config alias when testing extended config spaceAlex Williamson
When a PCI-to-PCIe bridge is stacked on a PCIe-to-PCI bridge, we can have PCIe endpoints masked by a conventional PCI bus. This makes the extended config space of the PCIe endpoint inaccessible. The PCIe-to-PCI bridge is supposed to handle any type 1 configuration transactions where the extended config offset bits are non-zero as an Unsupported Request rather than forward it to the secondary interface. As noted here, there are a couple known offenders to this rule. These bridges drop the extended offset bits, resulting in the conventional config space being aliased many times across the extended config space. For Intel NICs, this alias often seems to expose a bogus SR-IOV cap. Stacking bridges may seem like an uncommon scenario, but note that any conventional PCI slot in a modern PC is already the secondary interface of an onboard PCIe-to-PCI bridge. The user need only add a PCI-to-PCIe adapter and PCIe device to encounter this problem. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2014-05-27w1: optional bundling of netlink kernel repliesDavid Fries
Applications can submit a set of commands in one packet to the kernel, and in some cases it is required such as reading the temperature sensor results. This adds an option W1_CN_BUNDLE to the flags of cn_msg to request the kernel to reply in one packet for efficiency. The cn_msg flags now check for unknown flag values and return an error if one is seen. See "Proper handling of unknown flags in system calls" http://lwn.net/Articles/588444/ This corrects the ack values returned as per the protocol standard, namely the original ack for status messages and seq + 1 for all others such as the data returned from a read. Some of the common variable names have been standardized as follows. struct cn_msg *cn struct w1_netlink_msg *msg struct w1_netlink_cmd *cmd struct w1_master *dev When an argument and a function scope variable would collide, add req_ to the argument.

2014-05-27regulator: arizona-ldo1: add missing #includeArnd Bergmann
commit 2cce4be9e6b8 "regulator: arizona-ldo1: Add processing of init_data from device tree" added a call to of_get_child_by_name() but did not add an #include to the header file declaring that function. I got a build error when doing randconfig testing on this, which is fixed by this patch to include of.h. drivers/regulator/arizona-ldo1.c:192:2: error: implicit declaration of function 'of_get_child_by_name' [-Werror=implicit-function-declaration] drivers/regulator/arizona-ldo1.c:193:2: error: implicit declaration of function 'of_parse_phandle' [-Werror=implicit-function-declaration] drivers/regulator/arizona-ldo1.c:213:2: error: implicit declaration of function 'of_node_put' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-05-27driver core: Move driver_data back to struct deviceJean Delvare
Having to allocate memory as part of dev_set_drvdata() is a problem because that memory may never get freed if the device itself is not created. So move driver_data back to struct device. This is a partial revert of commit b4028437. Signed-off-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-05-27tty: n_hdlc: Drop redundant error messageJean Delvare
On initialization failure, an error message is already printed with level KERN_ERR, no need to print another one with level KERN_INFO. Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-05-27serial: pch_uart: Fix Kconfig dependenciesJean Delvare
The pch_uart driver is for a companion chip to the Intel Atom E600 series processors. These are 32-bit x86 processors so the driver is only needed on X86_32. Add COMPILE_TEST as an alternative, so that the driver can still be build-tested elsewhere.

2014-05-27usb: phy: add run-time dependencies to R-Car driverJean Delvare
The Renesas R-Car USB PHY driver only supports the R8A7778 and R8A7779, it isn't useful on other systems unless build testing.
