Support reads through polling, without any IRQ. The main reason is performance; profiling shows that the first IRQ comes quickly on our specific hardware.

2024-04-23spi: mux: Fix master controller settings after mux selectHeikki Keranen1-0/+2
In some cases SPI child devices behind spi-mux require different settings like: max_speed_hz, mode and bits_per_word. Typically the slave device driver puts the settings in place and calls spi_setup() once during probe and assumes they stay in place for all following spi transfers. However spi-mux forwarded spi_setup() -call to SPI master driver only when slave driver calls spi_setup(). If second slave device was accessed meanwhile and that driver called spi_setup(), the settings did not change back to the first spi device. In case of wrong max_speed_hz this caused spi trasfers to fail. This commit adds spi_setup() call after mux is changed. This way the right device specific parameters are set to the master driver. The fix has been tested by using custom hardware and debugging spi master driver speed settings.

2024-04-17Add bridged amplifiers to cs42l43Mark Brown833-4843/+10722
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: In some cs42l43 systems a couple of cs35l56 amplifiers are attached to the cs42l43's SPI and I2S. On Windows the cs42l43 is controlled by a SDCA class driver and these two amplifiers are controlled by firmware running on the cs42l43. However, under Linux the decision was made to interact with the cs42l43 directly, affording the user greater control over the audio system. However, this has resulted in an issue where these two bridged cs35l56 amplifiers are not populated in ACPI and must be added manually. There is at least an SDCA extension unit DT entry we can key off. The process of adding this is handled using a software node, firstly the ability to add native chip selects to software nodes must be added. Secondly, an additional flag for naming the SPI devices is added this allows the machine driver to key to the correct amplifier. Then finally, the cs42l43 SPI driver adds the two amplifiers directly onto its SPI bus. An additional series will follow soon to add the audio machine driver parts (in the sof-sdw driver), however that is fairly orthogonal to this part of the process, getting the actual amplifiers registered.

2024-04-16gpio: swnode: Add ability to specify native chip selects for SPICharles Keepax3-0/+57
SPI devices can specify a cs-gpios property to enumerate their chip selects. Under device tree, a zero entry in this property can be used to specify that a particular chip select is using the SPI controllers native chip select, for example: cs-gpios = <&gpio1 0 0>, <0>; Here, the second chip select is native. However, when using swnodes there is currently no way to specify a native chip select. The proposal here is to register a swnode_gpio_undefined software node, that can be specified to allow the indication of a native chip select. For example: static const struct software_node_ref_args device_cs_refs[] = { { .node = &device_gpiochip_swnode, .nargs = 2, .args = { 0, GPIO_ACTIVE_LOW }, }, { .node = &swnode_gpio_undefined, .nargs = 0, }, }; Register the swnode as the gpiolib is initialised and check in swnode_get_gpio_device() if the returned node matches swnode_gpio_undefined and return -ENOENT, which matches the behaviour of the device tree system when it encounters a 0 phandle.
