Pull spi updates from Mark Brown: "This has been a fairly quiet release for SPI, though it is likely that the next release will have some big changes as there's some preparatory work for multiple chip select support gone in - the rest of the code is on the list but will need to be rebased onto -rc1. Otherwise there's a couple of new tunables for chip select timings, some new devices and smaller device specific updates and fixes. - Support for configuring the hold and minimum inactive times for chip selects. - Beginnings of support for supporting devices which have multiple chip selects on a single device. - Support for newer Broadcom HSSPI and Intel controllers, Silicon Labs EM3581 and SI3210" * tag 'spi-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (67 commits) spi: dt-bindings: qcom,spi-qcom-qspi: document OPP and power-domains spi: spidev: drop the incorrect notice from Kconfig spi: bcm63xx-hsspi: fix error code in probe spi: bcmbca-hsspi: Fix error code in probe() function spi: synquacer: Fix timeout handling in synquacer_spi_transfer_one() spi: intel: Check number of chip selects after reading the descriptor spi: xilinx: add force_irq for QSPI mode spi: spi-st-ssc: convert to DT schema spi: Reorder fields in 'struct spi_transfer' spi: cadence-quadspi: use STIG mode for small reads spi: cadence-quadspi: setup ADDR Bits in cmd reads spi: cadence-quadspi: Add flag for direct mode writes spi: cadence-quadspi: Reset CMD_CTRL Reg on cmd r/w completion MAINTAINERS: Remove file reference for Broadcom Broadband SoC HS SPI driver entry spi: bcm63xx-hsspi: bcmbca-hsspi: fix _be16 type usage MAINTAINERS: Add entry for Broadcom Broadband SoC HS SPI drivers spi: bcmbca-hsspi: Add driver for newer HSSPI controller spi: bcm63xx-hsspi: Disable spi mem dual io read op support spi: spi-mem: Allow controller supporting mem_ops without exec_op spi: bcm63xx-hsspi: Add prepend mode support ...

spi: spidev: drop the incorrect notice from Kconfig

2023-02-16T15:54:03+00:00

The spidev interface has been de-facto stable for many years. This notice has been unchanged since 2007 and is incorrect so remove it. Signed-off-by: Bartosz Golaszewski Link: https://lore.kernel.org/r/20230216123014.110541-1-brgl@bgdev.pl Signed-off-by: Mark Brown

spi: bcmbca-hsspi: Add driver for newer HSSPI controller

2023-02-10T21:36:45+00:00

The newer BCMBCA SoCs such as BCM6756, BCM4912 and BCM6855 include an updated SPI controller that add the capability to allow the driver to control chip select explicitly. Driver can control and keep cs low between the transfers natively. Hence the dummy cs workaround or prepend mode found in the bcm63xx-hsspi driver are no longer needed and this new driver is much cleaner.

spi: intel: Update help text of PCI and Platform drivers

2023-02-10T18:06:56+00:00

Modern intel hardware uses controllers that work in hardware sequencing mode. In this mode, the controller exposes a subset of operations, like read, write and erase, making it easier and less error-prone for use. On the other hand, most of the controllers handled by the platform driver use software sequencing that exposes the entire set of operations i.e. exposes the low level SPI-NOR opcodes to the software for use. Update PCI and Platform help text with this information.

spi: intel: Remove DANGEROUS tag from pci driver

2023-02-07T12:32:24+00:00

Modern CPUs exposes this controller as PCI device that only uses hardware sequencing capabilities which is safer than software sequencing. Leave the platform driver as *DANGEROUS* and update help text since most of these controllers are using software sequencing.

Nuvoton WPCM450 FIU SPI flash controller

2022-11-25T14:58:57+00:00

Merge series from Jonathan Neuschäfer : This patchset adds DT bindings and a driver for the Flash Interface Unit (FIU), the SPI flash controller in the Nuvoton WPCM450 BMC SoC. It supports four chip selects, and direct (memory-mapped) access to 16 MiB per chip. Larger flash chips can be accessed by software-defined SPI transfers. The existing NPCM7xx FIU driver is sufficitently incompatible with the WPCM450 FIU that I decided to write a new driver.
