2023-08-21spi: bcm-qspi: Simplify logic by using devm_platform_ioremap_resource_byname()Zhang Zekun1-6/+3
platform_get_resource_byname() and devm_ioremap_resource() can be replaced by devm_platform_ioremap_resource_byname(), which can simplify the code logic a bit, No functional change here.

2023-03-06spi: iproc-qspi: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-10-18spi: bcm-qspi: Make bcm_qspi_remove() return voidUwe Kleine-König1-1/+3
The function bcm_qspi_remove() returns zero unconditionally. Make it return void. This is a preparation for making platform remove callbacks return void.

2016-09-24spi: iproc-qspi: Add Broadcom iProc SoCs supportKamal Dasu1-0/+163
This spi driver uses the common spi-bcm-qspi driver and implements iProc SoCs specific interrupt controller. The common driver now calls the SoC handlers when present. Adding support for both muxed l1 and unmuxed interrupt sources.
