-Subject: [PATCH] spi: ath79: remove spi-master setup and cleanup assignment
-
-This removes the assignment of setup and cleanup functions for the ath79
-target. Assigning the setup-method will lead to 'setup_transfer' not
-being assigned in spi_bitbang_init.
-
-Also drop the redundant cleanup assignment, as this also happens in
-spi_bitbang_init.

-Subject: [PATCH] spi: sync up initial chipselect state
-
-When initially probing the SPI slave device, the call for disabling an
-SPI device without the SPI_CS_HIGH flag is not applied, as the
-condition for checking whether or not the state to be applied equals the
-one currently set evaluates to true.
-
-This however might not necessarily be the case, as the chipselect might
-be active.
-
-Add a force flag to spi_set_cs which allows to override this
-early access condition. Set it to false everywhere except when called
-from spi_setup to sync up the initial CS state.
-
-Fixes commit d40f0b6f2e21 ("spi: Avoid setting the chip select if we don't
-need to")

-Subject: [PATCH 1/2] spi: ath79: add SPI_MASTER_GPIO_SS flag
-
-Add the SPI_MASTER_GPIO_SS flag for the spi-ath79 driver. Otherwise,
-the custom chipselect function is never called. This breaks hardware,
-where the three dedicated chipselect lines are used instead of generic
-GPIO pins.
-
-Fixes commit 4a07b8bcd503 ("spi: bitbang: Make chipselect callback optional")
