* spi: xlp: Remove Netlogic XLP variantsRob Herring2021-11-151-8/+0
| | | | | | | | | | | | | | Netlogic XLP was removed in commit 95b8a5e0111a ("MIPS: Remove NETLOGIC support"). With those gone, the single platform left to support is Cavium ThunderX2. Remove the Netlogic variant and DT support. For simplicity, the existing kconfig name is retained.

* spi: Remove dev_err() usage after platform_get_irq()Stephen Boyd2019-08-021-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

* spi: xlp: fix error return code in xlp_spi_probe()Gustavo A. R. Silva2017-08-081-2/+2
| | | | | | | | | | | | | | | | platform_get_irq() returns an error code, but the spi-xlp driver ignores it and always returns -EINVAL. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure.

* spi: xlp: update for ARCH_VULCAN2Jayachandran C2017-03-131-0/+1
| | | | | | | | | | | | | ARCH_VULCAN arm64 platform (for Broadcom Vulcan ARM64 processors) has been discontinued. Cavium's ThunderX2 CN99XX (ARCH_THUNDER2) will be the next revision of the platform. Update compile dependencies and ACPI ID to reflect this change. There is not need to retain ARCH_VULCAN since the Vulcan processor was never in production and ARCH_VULCAN will be deleted soon.

* spi: xlp: Fix module autoload for OF registrationJavier Martinez Canillas2016-11-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/spi/spi-xlp.ko | grep alias alias: acpi*:BRCM900D:* After this patch: $ modinfo drivers/spi/spi-xlp.ko | grep alias alias: acpi*:BRCM900D:* alias: of:N*T*Cnetlogic,xlp832-spiC* alias: of:N*T*Cnetlogic,xlp832-spi Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
