2012-09-26serial: pl011: handle corruption at high clock speedsLinus Walleij1-1/+14
This works around a few glitches in the ST version of the PL011 serial driver when using very high baud rates, as we do in the Ux500: 3, 3.25, 4 and 4.05 Mbps. Problem Observed/rootcause: When using high baud-rates, and the baudrate*8 is getting close to the provided clock frequency (so a division factor close to 1), when using bursts of characters (so they are abutted), then it seems as if there is not enough time to detect the beginning of the start-bit which is a timing reference for the entire character, and thus the sampling moment of character bits is moving towards the end of each bit, instead of the middle. Fix: Increase slightly the RX baud rate of the UART above the theoretical baudrate by 5%. This will definitely give more margin time to the UART_RX to correctly sample the data at the middle of the bit period. Also fix the ages old copy-paste error in the very stressed comment, it's referencing the registers used in the PL010 driver rather than the PL011 ones.

2012-09-26Powerpc 8xx CPM_UART setting MAXIDL register proportionaly to baud rateChristophe Leroy1-0/+14
MAXIDL is the timeout after which a receive buffer is closed when not full if no more characters are received. We calculate it from the baudrate so that the duration is always the same at standard rates: about 4ms. At 9600 bauds it gives a timeout of 4 characters, which is the timeout on the 8250 UART.

2012-09-15mfd: core: Push irqdomain mapping out into devicesMark Brown53-111/+122
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

2012-09-14ACPI / PM: Use KERN_DEBUG when no power resources are foundAaron Lu1-1/+1
commit a606dac368eed5696fb38e16b1394f1d049c09e9 adds support to link devices which have _PRx, if a device does not have _PRx, a warning message will be printed. This commit is for ZPODD on Intel ZPODD capable platforms, on other platforms, it has no problem if there is no power resource for this device, so a warning here is not appropriate, change it to debug.

2012-09-14i2c: algo: pca: Fix mode selection for PCA9665Thomas Kavanagh1-3/+3
The code currently always selects turbo mode for PCA9665, no matter which clock frequency is configured. This is because it compares the clock frequency against constants reflecting (boundary / 100). Compare against real boundary frequencies to fix the problem.

2012-09-14ACPI / PM: Fix resource_lock dead lock in acpi_power_on_deviceLin Ming1-11/+23
Commit 0090def("ACPI: Add interface to register/unregister device to/from power resources") used resource_lock to protect the devices list that relies on power resource. It caused a mutex dead lock, as below acpi_power_on ---> lock resource_lock __acpi_power_on acpi_power_on_device acpi_power_get_inferred_state acpi_power_get_list_state ---> lock resource_lock This patch adds a new mutex "devices_lock" to protect the devices list and calls acpi_power_on_device in acpi_power_on, instead of __acpi_power_on, after the resource_lock is released.
