This driver has been added instead of improving spi-bcm53xx. It has some advantages: allows SPI speed control & hopefully doesn't have bug that was stopping us from using multiple SPI messages for writing flash data. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] spi: bcm-qspi: fix suspend/resume #ifdef
|
|
|
|
The two power management functions are define inside of an #ifdef
|
|
but referenced unconditionally, which is obviously broken when
|
|
CONFIG_PM_SLEEP is not set:
|
|
|
|
drivers/spi/spi-bcm-qspi.c:1300:13: error: 'bcm_qspi_suspend' undeclared here (not in a function)
|
|
drivers/spi/spi-bcm-qspi.c:1301:13: error: 'bcm_qspi_resume' undeclared here (not in a function)
|
|
|
|
This replaces the #ifdef with a __maybe_unused annotation that lets
|
|
the compiler figure out whether to drop the functions itself,
|
|
and uses SIMPLE_DEV_PM_OPS() to refer to the functions.
|
|
|
|
This will also fill the freeze/thaw/poweroff/restore callback
|
|
pointers in addition to suspend/resume, but as far as I can tell,
|
|
this is what we want.
