21a1bc6a90 ARM: dts: meson: switch TFLASH_VDD_EN pin to open drain on Odroid-C4
For the proper reboot Odroid-C4 board requires to switch TFLASH_VDD_EN
pin to the high impedance mode, otherwise the board is stuck in the
middle of loading early stages of the bootloader from SD card.

This can be achieved by using the OPEN_DRAIN flag instead if the
ACTIVE_HIGH, what will leave the pin in input to achieve high state (pin
has the pull-up) and solve the issue.

fec7bf0460 spi: dw: Add mem_ops
The designware ssi device has "broken" chip select behaviour [1], and needs
specific manipulation to use the built-in chip select. The existing fix is
to use an external GPIO for chip select, but typically the K210 has SPI3
directly connected to a flash chip with dedicated pins. This makes it
impossible to use the spi_xfer function to use spi, since the CS is
de-asserted in between calls.  This patch adds an implementation of
exec_op, which gives correct behaviour when reading/writing spi flash.

This patch also rearranges the headers to conform to U-Boot style.

58875790fd spi: dw: Add support for multiple CTRLR0 layouts
CTRLR0 can have several different layouts depending on the specific device
(dw-apb-ssi vs dwc-ssi), and specific parameters set during synthesis.
Update the driver to support three specific configurations: dw-apb-ssi with
SSI_MAX_XFER_SIZE=16, dw-apb-ssi with SSI_MAX_XFER_SIZE=32, and dwc-ssi.

dw-apb-ssi is the version of the device on Altera/Intel SoCFPGAs, MSCC
SoCs, and Canaan Kendryte K210 SoCs. This is the only version this driver
supported before this change. The register layout before version 3.23a is:

|   31 .. 16  |
| other stuff |

|   15 .. 10  | 9 .. 8 | 7 .. 6 | 5 .. 4 | 3 .. 0 |
| other stuff |  TMOD  |  MODE  |  FRF   |  DFS   |

Note that DFS (Data Frame Size) is only 4 bits, limiting transfers to data
frames of 16 bits or less.

In version 3.23a, the SSI_MAX_XFER_SIZE parameter was introduced. This
parameter defaults to 16 (resulting in the same layout as prior versions),
but may also be set to 32. To allow setting longer data frame sizes, a new
DFS_32 register was introduced:

|   31 .. 21  | 20 .. 16 |
| other stuff |  DFS_32  |

|   15 .. 10  | 9 .. 8 | 7 .. 6 | 5 .. 4 |  3 .. 0   |
| other stuff |  TMOD  |  MODE  |  FRF   | all zeros |

The old DFS field no longer controls the data frame size. To detect this
layout, we try writing 0xF to DFS. If we read back 0x0, then this device
has SSI_MAX_XFER_SIZE=32.

dwc-ssi is the version of the device on Intel Keem Bay SoCs and Canaan
Kendryte K210 SoCs. The layout of ctrlr0 is:

|   31 .. 16  |
| other stuff |

|   15 .. 12  | 11 .. 10 | 9 .. 8 | 7 .. 6 | 4 .. 0 |
| other stuff |   TMOD   |  MODE  |  FRF   | DFS_32 |

The semantics of the fields have not changed since the previous version.
However, SSI_MAX_XFER_SIZE is effectively always 32.

To support these different layouts, we model our approach on the one
which the Linux kernel has taken. During probe, the driver calls an init
function stored in driver_data. This init function is responsible for
determining the layout of CTRLR0, and supplying the update_cr0 function.

The style of and information behind this commit is based on the Linux MMIO
driver for these devices. Specific reference was made to the series adding
support for Intel Keem Bay SoCs [1].

237e5880f8 spi: dw: Add SoC-specific compatible strings
This adds SoC-specific compatible strings to all users of the designware
spi device. This will allow for the correct driver to be selected for each
device. Where it is publicly documented, a compatible string for the
specific device version has also been added. Devices without
publicly-documented device versions include MSCC SoCs, and Arc Socs. All
compatible strings except those for SoCFPGAs and some of the versioned
strings have been taken from Linux.

Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly
necessary. However, it is a good cleanup and brings things closer to Linux.

This should reduce the size of the struct, and also groups more similar
