2025-04-07ASoC: loongson: Replace deprecated PCI functionsPhilipp Stanner
pcim_iomap_table() and pcim_iomap_regions() have been deprecated. Replace them with pcim_iomap_region(). Signed-off-by: Philipp Stanner <phasta@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250404121911.85277-13-phasta@kernel.org
2024-09-10ASoC: loongson: Add the correct judgement returnTang Bin
Use the function dev_err_probe can simplify code, but the error return should not be deleted, that is unreasonable, thus fix it.

Error handling in probe() can be a bit simpler with dev_err_probe(). Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Link: https://patch.msgid.link/07855aa6c290ec826d63e68b898e7f4afac5e30d.1725844530.git.zhoubinbin@loongson.cn Signed-off-by: Mark Brown <broonie@kernel.org>
2024-09-09ASoC: loongson: Simplify probe() with local dev variableBinbin Zhou
Simplify the probe() function by using local 'dev' instead of &pdev->dev. Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Link: https://patch.msgid.link/1984a20930da515e2a478b02159f83c02498f6be.1725844530.git.zhoubinbin@loongson.cn Signed-off-by: Mark Brown <broonie@kernel.org>
2024-03-28ASoC: loongson: i2s/pci: drop driver owner assignmentKrzysztof Kozlowski
PCI core in pci_register_driver() already sets the .owner, so driver does not need to.

2023-06-22ASoC: loongson: fix address space confusionArnd Bergmann
The i2s driver uses the mapped __iomem address of the FIFO as the DMA address for the device. This apparently works on loongarch because of the way it handles __iomem pointers as aliases of physical addresses, but this is not portable to other architectures and causes a compiler warning when dma addresses are not the same size as pointers: sound/soc/loongson/loongson_i2s_pci.c: In function 'loongson_i2s_pci_probe': sound/soc/loongson/loongson_i2s_pci.c:110:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 110 | tx_data->dev_addr = (dma_addr_t)i2s->reg_base + LS_I2S_TX_DATA; | ^ sound/soc/loongson/loongson_i2s_pci.c:113:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 113 | rx_data->dev_addr = (dma_addr_t)i2s->reg_base + LS_I2S_RX_DATA; | ^ Change the driver to instead use the physical address as stored in the PCI BAR resource directly. Since 'dev_addr' is a 32-bit address, I think this results in the same truncated address on loongarch but is otherwise closer to portable code and avoids the warning.

2023-06-15ASoC: Add support for Loongson I2S controllerYingkun Meng
Loongson I2S controller is found on 7axxx/2kxxx chips from loongson, it is a PCI device with two private DMA controllers, one for playback, the other for capture. The driver supports the use of DTS or ACPI to describe device resources.
