2010-08-02drm/radeon/kms: add support for internal thermal sensors (v3)Alex Deucher
rv6xx/rv7xx/evergreen families supported; older asics did not have an internal thermal sensor. Note, not all oems use the internal thermal sensor, so it's only exposed in cases where it is used. Note also, that most laptops use an oem specific ACPI solution for GPU thermal information rather than using the internal thermal sensor directly. v2: export millidegrees celsius, use hwmon device properly. v3: fix Kconfig Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-08-01ata_piix: fix locking around SIDPR accessTejun Heo
SIDPR window registers are shared across ports and as each access is done in two steps, accesses to different ports under EH may race. This primarily is caused by incorrect host locking in EH context and should be fixed by defining locking requirements for each EH operation which can be used during EH and enforcing them but for now work around the problem by adding a dedicated SIDPR lock and grabbing it for each SIDPR access.

2010-08-01ahci_platform: Remove unneeded ahci_driver.probe assignmentAnton Vorontsov
The driver is using platform_driver_probe() during initialization, so ahci_driver.probe hook is never used. But it causes the following (harmless, luckily) section mismatch: WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference from the variable ahci_driver to the function .init.text:ahci_probe() This patch removes the ahci_driver.probe assignment, thus fixes the warning. p.s. Note that there's another patch[1] from Rene Bolldorf that tried to solve the same issue by __refdata annotation. __refdata says that this reference is actually OK, but in fact it is not OK, because dereferencing .probe() will cause problems. So the proper fix is to remove the assignment.

2010-08-01powerpc/5200/i2c: improve i2c bus error recoveryAlbrecht Dreß
This patch improves the recovery of the MPC's I2C bus from errors like bus hangs resulting in timeouts: 1. make the bus timeout configurable, as it depends on the bus clock and the attached slave chip(s); default is still 1 second; 2. detect any of the cases indicated by the CF, BB and RXAK MSR flags if a timeout occurs, and add a missing (required) MAL reset; 3. use a more reliable method to fixup the bus if a hang has been detected. The sequence is sent 9 times which seems to be necessary if a slave "misses" more than one clock cycle. For 400 kHz bus speed, the fixup is also ~70us (81us vs. 150us) faster. Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors and NXP IO expander chips attached to the i2c. Changes vs. v1: - use improved bus fixup sequence for all chips (not only the 5200) - calculate real clock from defaults if no clock is given in the device tree - better description (I hope) of the changes. I didn't split the changes in this file into three parts as recommended by Grant, as they actually belong together (i.e. they address one single problem, just in three places of one single source file).

2010-08-01powerpc/fsl-diu-fb: Support setting display mode using EDIDAnatolij Gustschin
Adds support for encoding display mode information in the device tree using verbatim EDID block. If the EDID entry in the DIU node is present, the driver will build mode database using EDID data and allow setting the display modes from this database. Otherwise display mode will be set using mode entries from driver's internal database as usual. This patch also updates device tree bindings.

2010-08-01powerpc/5121: shared DIU framebuffer supportAnatolij Gustschin
MPC5121 DIU configuration/setup as initialized by the boot loader currently will get lost while booting Linux. As a result displaying the boot splash is not possible through the boot process. To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.

On MPC5121e Rev 2.0 re-configuring the DIU area descriptor by writing new descriptor address doesn't always work. As a result, DIU continues to display using old area descriptor even if the new one has been written to the descriptor register of the plane. Add the code from Freescale MPC5121EADS BSP for writing descriptor addresses properly. This fixes the problem for Rev 2.0 silicon.

2010-08-01of/platform: Register of_platform_drivers with an "of:" prefixGrant Likely
Currently there are some drivers in tree which register both a platform_driver and an of_platform_driver with the same name. This is a temporary situation until all the relevant of_platform_drivers are converted to be normal platform_drivers. Until then, this patch gives all the of_platform_drivers an "of:" prefix to protect against bogus matches and namespace conflicts.
2010-08-01of/address: Clean up function declarationsGrant Likely
This patch moves the declaration of of_get_address(), of_get_pci_address(), and of_pci_address_to_resource() out of arch code and into the common linux/of_address header file. This patch also fixes some of the asm/prom.h ordering issues. It still includes some header files that it ideally shouldn't be, but at least the ordering is consistent now so that of_* overrides work. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2010-07-31ARM: AMBA: Add pclk support to AMBA bus infrastructureRussell King
Some platforms gate the pclk (APB - the bus - clock) to the peripherals for power saving, along with the functional clock. When devices are accessed without pclk enabled, the kernel will oops. This gives them two options: 1. Leave all clocks on all the time. 2. Attempt to gate pclk along with the functional clock. (With some hardware, pclk and the functional clock are gated by a single bit in a register.) (1) has the disadvantage that it causes increased power usage, which is bad news for battery operated devices. (2) can lead to kernel oops if registers are accessed without the functional clock being enabled. So, introduce the apb_pclk signal in such a way existing drivers don't need to be updated. Essentially, this means we guarantee that: 1. pclk will be enabled whenever the driver is bound to a device - from probe() to remove() time. 2. pclk will also be enabled when reading the primecell IDs from the device. In order to allow drivers to be incrementally updated to achieve greater power savings, we provide two additional calls to allow drivers to manage the pclk - amba_pclk_enable()/amba_pclk_disable().

2010-07-30bonding: prevent sysfs from allowing arp monitoring with alb/tlbAndy Gospodarek
When using module options arp monitoring and balance-alb/balance-tlb are mutually exclusive options. Anytime balance-alb/balance-tlb are enabled mii monitoring is forced to 100ms if not set. When configuring via sysfs no checking is currently done. Handling these cases with sysfs has to be done a bit differently because we do not have all configuration information available at once. This patch will not allow a mode change to balance-alb/balance-tlb if arp_interval is already non-zero. It will also not allow the user to set a non-zero arp_interval value if the mode is already set to balance-alb/balance-tlb. They are still mutually exclusive on a first-come, first serve basis.
