2017-09-25spi: spi-fsl-dspi: Fix incorrect freeing of DMA allocated buffersSanchayan Maity
Buffers allocated with a call to dma_alloc_coherent should be freed with dma_free_coherent instead of the currently used devm_kfree. Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Zhikang Zhang <zhikang.zhang@nxp.com>
2017-09-25spi: spi-fsl-dspi: Fix SPI transfer issue when using multiple SPI_IOC_MESSAGESanchayan Maity
Current DMA implementation had a bug where the DMA transfer would exit the loop in dspi_transfer_one_message after the completion of a single transfer. This results in a multi message transfer submitted with SPI_IOC_MESSAGE to terminate incorrectly without an error.

commit 1d77040bde2d21dc7db575d4b43c1da24c94cca1 [context adjustment] Add support for the LS1046a PCIe controller.

2017-09-25pci:add support aer/pme interrupts with none MSI/MSI-X/INTx modePo Liu
[pcie part] On some platforms, root port doesn't support MSI/MSI-X/INTx in RC mode. When chip support the aer/pme interrupts with none MSI/MSI-X/INTx mode, maybe there is interrupt line for aer pme etc. Search the interrupt number in the fdt file. Then fixup the dev->irq with it.

2017-09-25irqchip/ls-scfg-msi: add MSI affinity supportMinghuan Lian
For LS1046a and LS1043a v1.1, the MSI controller has 4 MSIRs and 4 GIC SPI interrupts which can be associated with different Core. So we can support affinity to improve the performance. The MSI message data is a byte for Layerscape MSI. 7 6 5 4 3 2 1 0 | - | IBS | SRS | SRS bit0-1 is to select a MSIR which is associated with a CPU. IBS bit2-6 of ls1046, bit2-4 of ls1043a v1.1 is to select bit of the MSIR. With affinity, only bits of MSIR0(srs=0 cpu0) are available. All other bits of the MSIR1-3(cpu1-3) are reserved. The MSI hwirq always equals bit index of the MSIR0. When changing affinity, MSI message data will be appended corresponding SRS then MSI will be moved to the corresponding core. But in affinity mode, there is only 8 MSI interrupts for a controller of LS1043a v1.1. It cannot meet the requirement of the some PCIe devices such as 4 ports Ethernet card. In contrast, without affinity, all MSIRs can be used for core 0, the MSI interrupts can up to 32. So the parameter is added to control affinity mode. "lsmsi=no-affinity" will disable affinity and increase MSI interrupt number. Signed-off-by: Minghuan Lian <Minghuan.Lian@nxp.com> Signed-off-by: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>
2017-09-25irqchip/ls-scfg-msi: add LS1043a v1.1 MSI supportMinghuan Lian
A MSI controller of LS1043a v1.0 only includes one MSIR and is assigned one GIC interrupt. In order to support affinity, LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts. But the MSIR has the different offset and only supports 8 MSIs. The bits between variable bit_start and bit_end in structure ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and msir_base are added to describe the difference of MSI between LS1043a v1.1 and other SoCs.

2017-09-25irqchip/ls-scfg-msi: add LS1046a MSI supportMinghuan Lian
LS1046a includes 4 MSIRs, each MSIR is assigned a dedicate GIC SPI interrupt and provides 32 MSI interrupts. Compared to previous MSI, LS1046a's IBS(interrupt bit select) shift is changed to 2 and total MSI interrupt number is changed to 128. The patch adds structure 'ls_scfg_msir' to describe MSIR setting and 'ibs_shift' to store the different value between the SoCs.

If PHY_CLK_VALID bit is still not set even after 5 retries, it would be safe to deaclare that PHY clock is not available. This erratum is applicable for USBDR less then ver 2.4.
