2020-05-05spi: dw: Add update_cr0() callback to update CTRLR0Wan Ahmad Zainie4-11/+48
This patch adds update_cr0() callback, in struct dw_spi. Existing code that configure register CTRLR0 is moved into a new function, dw_spi_update_cr0(), and this will be the default.

2020-05-04spi: amd: Drop superfluous member from struct amd_spiLukas Wunner1-4/+2
The AMD SPI driver stores a pointer to the spi_master in struct amd_spi so that it can get from the latter to the former in amd_spi_fifo_xfer(). It's simpler to just pass the pointer from the sole caller amd_spi_master_transfer() and drop the pointer from struct amd_spi.

2020-05-04spi: amd: Fix refcount underflow on removeLukas Wunner1-12/+1
The AMD SPI driver calls spi_master_put() in its ->remove() hook even though the preceding call to spi_unregister_master() already drops a ref, thus leading to a refcount underflow. Drop the superfluous call to spi_master_put(). This only leaves the call to spi_unregister_master() in the ->remove() hook, so it's safe to change the ->probe() hook to use the devm version of spi_register_master() and drop the ->remove() hook altogether.

2020-05-04spi: amd: Drop duplicate driver data assignmentsLukas Wunner1-2/+0

2020-05-04spi: amd: Fix duplicate iounmap in error pathLukas Wunner1-3/+1
The AMD SPI driver uses devm_ioremap_resource() to map its registers, so they're automatically unmapped via device_release() when the last ref on the SPI controller is dropped. The additional iounmap() in the ->probe() error path is thus unnecessary.

With a couple allies at Intel, and much badgering, I got confirmation from Intel that at least BXT suffers from the same SPI chip-select issue as Cannonlake (and beyond). The issue being that after going through runtime suspend/resume, toggling the chip-select line without also sending data does nothing. Add the quirk to BXT to briefly toggle dynamic clock gating off and on, forcing the fabric to wake up enough to notice the CS register change.

2020-04-21spi: orion: Convert to use GPIO descriptorsLinus Walleij1-54/+16
This converts the Orion SPI master to use GPIO descriptors. The SPI core will obtain and manage the CS GPIOs, if any are defined. I make one sematic change: when a certain chip select is using a GPIO line instead of the native CS I simply just enable the 1:1 mapped native CS that would have been used if the GPIO was not there. As we set the SPI_MASTER_GPIO_SS the .set_cs() callback will be called for all chip selects whether native or not, and the important thing for the driver is that the previous native chip select (if any) is deasserted, which other chip select is asserted instead does not really matter. The previous code went to great lengths to ascertain that the first hw CS which was hiding behind a GPIO line was used for all cases when the line is not using native chip select but this should not matter at all, just use the one "underneath" the GPIO at all times. When a GPIO is used for CS, the SPI_CS_HIGH flag is enforced, so the native chip select is also inverted. But that should not matter since we are not using it anyways.

2020-04-21spi: bcm-qspi: Drive MSPI peripheral SSb pin on cs_changeKamal Dasu1-7/+12
As per the spi core implementation for MSPI devices when the transfer is the last one in the message, the chip may stay selected until the next transfer. On multi-device SPI busses with nothing blocking messages going to other devices, this is just a performance hint; starting a message to another device deselects this one. But in other cases, this can be used to ensure correctness. Some devices need protocol transactions to be built from a series of spi_message submissions, where the content of one message is determined by the results of previous messages and where the whole transaction ends when the chipselect goes intactive. On CS change after completing the last serial transfer, the MSPI driver drives SSb pin CDRAM register correctly according comments in core spi.h as shown below: case 1) EOM =1, cs_change =0: SSb inactive case 2) EOM =1, cs_change =1: SSb active case 3) EOM =0, cs_change =0: SSb active case 4) EOM =0, cs_change =1: SSb inactive Signed-off-by: Kamal Dasu <kdasu.kdev@gmail.com> Link: https://lore.kernel.org/r/20200420190853.45614-5-kdasu.kdev@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>

The variable ms is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

There are few ALSA core updates (merely API cleanups and sparse fixes), with the majority of other changes are found in ASoC scene.
