Luis de Bethencourt c9e97b3cb2 spi: meson: Fix module autoload for OF platform driver
This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Krzysztof Kozlowski 9caf5067b9 spi: meson: Constify struct regmap_config
The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

Rafael J. Wysocki 47164fdb3b spi: Replace CONFIG_PM_RUNTIME with CONFIG_PM
A couple of new CONFIG_PM_RUNTIME users have been added recently
in the SPI subsystem.

However, after commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so
#ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to
depend on CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/spi/ (again).

kbuild test robot 008c2a2ef0 spi: meson: meson_spifc_setup_speed() can be static
drivers/spi/spi-meson-spifc.c:171:6: sparse: symbol 'meson_spifc_setup_speed' was not declared. Should it be static?

Beniamino Galvani c3e4bc5434 spi: meson: Add support for Amlogic Meson SPIFC
This is a driver for the Amlogic Meson SPIFC (SPI flash controller),
which is one of the two SPI controllers available on the SoC. It
doesn't support DMA and has a 64-byte unified transmit/receive buffer.

The device is optimized for interfacing with SPI NOR memories and
allows the execution of standard operations such as read, page
program, sector erase, etc. in a simplified way, toggling a bit in a
dedicated register. The driver doesn't use those predefined commands
and relies only on custom transfers.
