spi: Replace all spi->chip_select and spi->cs_gpiod references with function call

2023-03-11T12:34:01+00:00

Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod
members of struct spi_device to be an array. But changing the type of these
members to array would break the spi driver functionality. To make the
transition smoother introduced four new APIs to get/set the
spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and
spi->cs_gpiod references with get or set API calls.
While adding multi-cs support in further patches the chip_select & cs_gpiod
members of the spi_device structure would be converted to arrays & the
"idx" parameter of the APIs would be used as array index i.e.,
spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

spi: spi-falcon: remove check for 'delay_usecs'

2021-03-12T14:30:48+00:00

The 'delay_usecs' field is being removed from the spi_transfer struct.
This change removes it from the SPI Falcon driver.

spi: spi-falcon: extend warning to `delay` as well

2019-10-15T10:46:57+00:00

The WARN_ON macro prints a warning in syslog if `delay_usecs` is non-zero.
However, with the new intermediate `delay`, the warning should also be
printed.

spi: spi-falcon: drop check of boot select

2017-09-01T10:33:22+00:00

Do not check which flash type the SoC was booted from before
using this driver. Assume that the device tree is correct and use this
driver when it was added to device tree. This also removes a build
dependency to the SoC code.

All device trees I am aware of only have one correct flash device entry
in it. The device tree is anyway bundled with the kernel in all systems
using device tree I know of.

The boot mode can be specified with some pin straps and will select the
flash type the rom code will boot from. One SPI, NOR or NAND flash chip
can be connect to the EBU and used to load the first stage boot loader
from.
