2023-03-06spi: meson-spifc: Convert to platform remove callback returning voidUwe Kleine-König
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.

2022-01-07spi: spi-meson-spifc: Add missing pm_runtime_disable() in meson_spifc_probeMiaoqian Lin
If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable(). Add missing pm_runtime_disable() for meson_spifc_probe.

2014-12-19spi: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki
A couple of new CONFIG_PM_RUNTIME users have been added recently in the SPI subsystem. However, after commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/spi/ (again). Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Mark Brown <broonie@kernel.org>

2014-11-24spi: meson: Add support for Amlogic Meson SPIFCBeniamino Galvani
This is a driver for the Amlogic Meson SPIFC (SPI flash controller), which is one of the two SPI controllers available on the SoC. It doesn't support DMA and has a 64-byte unified transmit/receive buffer. The device is optimized for interfacing with SPI NOR memories and allows the execution of standard operations such as read, page program, sector erase, etc. in a simplified way, toggling a bit in a dedicated register. The driver doesn't use those predefined commands and relies only on custom transfers. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
