2017-11-29mtd: nand: allow drivers to request minimum alignment for passed bufferMasahiro Yamada
In some cases, nand_do_{read,write}_ops is passed with unaligned ops->datbuf. Drivers using DMA will be unhappy about unaligned buffer. The new struct member, buf_align, represents the minimum alignment the driver require for the buffer. If the buffer passed from the upper MTD layer does not have enough alignment, nand_do_*_ops will use bufpoi.

2017-11-29mtd: nand: Wait for PAGEPROG to finish in drivers setting ↵Boris Brezillon
NAND_ECC_CUSTOM_PAGE_ACCESS Drivers setting NAND_ECC_CUSTOM_PAGE_ACCESS are supposed to handle the full read/write page sequence, and waiting for a page to actually be programmed is part of this write-page sequence. This is also what is done in ->write_oob_xxx() hooks, so let's do that in ->write_page_xxx() as well to make it consistent.

2017-11-29mtd: nand: Fix data interface configuration logicBoris Brezillon
When changing from one data interface setting to another, one has to ensure a specific sequence which is described in the ONFI spec. One of these constraints is that the CE line has go high after a reset before a command can be sent with the new data interface setting, which is not guaranteed by the current implementation. Rework the nand_reset() function and all the call sites to make sure the CE line is asserted and released when required. Also make sure to actually apply the new data interface setting on the first die.

2017-11-29mtd: nand: automate NAND timings selectionBoris Brezillon
The NAND framework provides several helpers to query timing modes supported by a NAND chip, but this implies that all NAND controller drivers have to implement the same timings selection dance. Also currently NAND devices can be resetted at arbitrary places which also resets the timing for ONFI chips to timing mode 0. Provide a common logic to select the best timings based on ONFI or ->onfi_timing_mode_default information. Hook this into nand_reset() to make sure the new timing is applied each time during a reset. NAND controller willing to support timings adjustment should just implement the ->setup_data_interface() method.

2017-11-29mtd: nand: Introduce nand_data_interfaceSascha Hauer
Currently we have no data structure to fully describe a NAND timing. We only have struct nand_sdr_timings for NAND timings in SDR mode, but nothing for DDR mode and also no container to store both types of timing. This patch adds struct nand_data_interface which stores the timing type and a union of different timings. This can be used to pass to drivers in order to configure the timing.

2017-11-29mtd: nand: Create a NAND reset functionSascha Hauer
When NAND devices are resetted some initialization may have to be done, like for example they have to be configured for the timing mode that shall be used. To get a common place where this initialization can be implemented create a nand_reset() function. This currently only issues a NAND_CMD_RESET to the NAND device. The places issuing this command manually are replaced with a call to nand_reset().

2017-11-29mtd: nand: Add an option to maximize the ECC strengthBoris Brezillon
The generic NAND DT bindings allows one to tweak the ECC strength and step size to their need. It can be used to lower the ECC strength to match a bootloader/firmware config, but might also be used to get a better reliability. In the latter case, the user might want to use the maximum ECC strength without having to explicitly calculate the exact value (this value not only depends on the OOB size, but also on the NAND controller, and can be tricky to extract). Add a generic 'nand-ecc-maximize' DT property and the associated NAND_ECC_MAXIMIZE flag, to let ECC controller drivers select the best ECC strength and step-size on their own.

2017-11-28arm64: zynqmp: Add SMMU support for SATA IPAnurag Kumar Vulisha
AXI master interface in CEVA AHCI controller requires two unique Write/Read ID tags per port. This is because, ahci controller uses different AXI ID[3:0] bits for identifying non-data transfers(like reading descriptors, updating PRD tables, etc) and data transfers (like sending/receiving FIS).To make SMMU work with SATA we need to add correct SMMU stream id for SATA. SMMU stream id for SATA is determined based on the AXI ID[1:0] as shown below SATA SMMU ID = <TBU number>, 0011, 00, 00, AXI ID[1:0] Note: SATA in ZynqMp uses TBU1 so TBU number = 0x1, so SMMU ID = 001, 0011, 00, 00, AXI ID[1:0] Since we have four different AXI ID[3:0] (2 for port0 & 2 for port1 as said above) we get four different SMMU stream id's combinations for SATA. These AXI ID can be configured using PAXIC register. In this patch we assumed the below AXI ID values Read ID/ Write ID for Non-Data Port0 transfers = 0 Read ID/ Write ID for Data Port0 transfers = 1 Read ID/ Write ID for Non-Data Port1 transfers = 2 Read ID/ Write ID for Data Port1 transfers = 3 Based on the above values,SMMU stream ID's for SATA will be 0x4c0 & 0x4c1 for PORT0, 0x4c2 & 0x4c3 for PORT1. These values needed to be added to iommus dts property. This patch does the same. Signed-off-by: Anurag Kumar Vulisha <anuragku@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
