spi: mtk_snor: add support for MTK SPI NOR controller

2021-01-29T15:35:14+00:00

This patch adds support for MTK SPI NOR controller, which you
can see on mt7622 & mt7629.

1. This controller is designed only for SPI NOR. We can't adjust
its bus clock dynamically. Set clock in dts instead.
2. This controller only supports 1-1-1 write mode.
3. Remove mtk_snor_match_read() since upper SPI-MEM layer already
handles command.
4. sf read/write/update commands are tested with this driver.

spi: add spi controller support for MediaTek MT7620 SoC

2021-01-24T20:39:26+00:00

This patch adds spi controller support for MediaTek MT7620 SoC.

The SPI controller supports two chip selects. These two chip selects are
implemented as two separate register groups, but they share the same bus
(DI/DO/CLK), only CS pins are dedicated for each register group.
Appearently these two register groups cannot operates simulataneously so
they are implemented as one controller.

spi: Add Qualcomm QUP SPI controller driver

2020-10-22T13:54:54+00:00

This patch adds support for the Qualcomm QUP SPI controller that is commonly found in most of Qualcomm SoC-s.

Driver currently supports v1.1.1, v2.1.1 and v2.2.1 HW.
FIFO and Block modes are supported, no support for DMA mode is planned.

xilinx: kconfig: Change Kconfig dependencies for Xilinx drivers

2020-09-23T08:31:40+00:00

Zynq/ZynqMP/Versal IPs should be possible to called also from Microblaze in
PL and vice versa. That's why change dependencies and do not limit enabling
just for some platforms.

This is follow up patch based on commit 664e16ce99a0 ("xilinx: kconfig:
Change Kconfig dependencies for Xilinx drivers").

spi: fsl_qspi: Support to use full AHB space on i.MX

2020-07-16T09:19:43+00:00

i.MX platforms provide large AHB mapped space for QSPI, each
controller has 256MB. However, current driver only maps small
size (AHB buffer size) of AHB space, this implementation
causes i.MX failed to boot M4 with QSPI XIP image.

Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX)
to address above problem.

When the config is set:
1. Full AHB space is divided to each CS.
2. A dedicated LUT entry is used for AHB read only.
3. The MODE instruction in LUT is replaced to standard ADDR instruction
4. The address in spi_mem_op is used to SFAR and AHB read
