2016-03-08imx6 device-tree: reduce SPI clock to datasheet maximumtoradex_imx_3.14.28_1.0.0_gaMax Krummenacher
According to the datasheet the SPI clock (for read) must not exceed 1 / 55ns for i.MX6Q/D and 1 / 43ns for i.MX6DL/S. Reflect that correctly in the device tree. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

2016-03-08tty: serial: imx: disable DCD and RI interruptsStefan Agner
If the UART is in DTE mode, the signals DCD and RI are inputs. In this case, the control bits in UCR3_DCD and UCR3_RI control the interrupt of those two inputs. The two bits are 1 on reset, hence leading to an interrupt if one of those signal changes... However, as of now the interrupt handler does not handle these interrupts, leading to a interrupt strom. Solve the issue by explicitly disabling the two interrupts during initialization. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
2016-03-08ARM: dts: imx: fix invalid #address-cells valueTim Harvey
The invalid value of #address-cells in the imx6 pcie host controller node causes of_irq_parse_raw() to incorrectly advance through an interrupt-map table of more than one interrupt. We also take the opportunity to drop the unused #size-cells here. This patch resolves this issue and allows proper interrupt mapping for an imx6 pcie host connected to a P2P bridge when using legacy interrupts.

2016-03-08PCI: Apalis GEN1 forcing quirkMarcel Ziswiler
The Apalis evaluation board needs to set the link speed to 2.5 GT/s (GEN1). The default link speed setting is 5 GT/s (GEN2). 0x98 is the Link Control 2 PCIe Capability Register of the PEX8605 PCIe switch. The switch supports link speed auto negotiation, but falsely sets the link speed to 5 GT/s.

With the 3.14.28 release of the kernel imx6_stop_mode_poweroff() does not enter stop mode. Thus the function does not switch of power but returns. This seems to be caused by the second processor which has been stopped. Set the WFI event mask for the stopped processor works around the issue.

2015-11-04ASoC: sgtl5000: Fix the cache handlingFabio Estevam
Since commit e5d80e82e32e (ASoC: sgtl5000: Convert to use regmap directly) a kernel oops is observed after a suspend/resume sequence. The kernel oops happens inside sgtl5000_restore_regs() as codec->reg_cache is no longer a valid pointer. Add the remaining register entries into sgtl5000_reg_defaults[] and remove sgtl5000_restore_regs() completely, which allows suspend/resume to work fine and make the code simpler. Tested on a im53-qsb board.

2015-11-03input: touchscreen: fusion: implement multitouch with slot handlingStefan Agner
According to multi-touch-protocol.txt the kernel knows two type of devices: - Type A: devices which provide anonymous contacts - Type B: devices which are capable of tracking individual contacts The Fusion touch screen is a Type B device: The Touch ID field allows to differentiate between 2 different fingers. This updates the driver to properly allocate a slot for each identified contact and use the helper functions available from the input core system.
