2023-08-25ata: sata_gemini: Add missing MODULE_DESCRIPTIONDamien Le Moal1-0/+1
Add the missing MODULE_DESCRIPTION() to avoid warnings such as: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/ata/sata_gemini.o when compiling with W=1.

2023-08-02ata: sata_gemini: 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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-08-02ata: Explicitly include correct DT includesRob Herring1-2/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2022-10-18ata: sata_gemini: Remove dependency on OF for compile testsDamien Le Moal1-1/+1
If CONFIG_OF is disabled, then using the macro of_match_ptr() results in the gemini_sata_of_match variable being unused, which generates a compilation warning and a compilation error if CONFIG_WERROR is enabled. Removing the use of this macro by directly assigning the gemini_sata_of_match match table to the .of_match_table field in the platform driver definition allows removing the dependency on OF for compile tests, thus improving compile test coverage.

2022-03-07ata: Drop commas after OF match table sentinelsGeert Uytterhoeven1-4/+2
It does not make sense to have a comma after a sentinel, as any new elements must be added before the sentinel. Add comments to clarify the purpose of the empty elements. Rewrap entries to a single line to have a consistent style.

2017-08-11ata: sata_gemini: Introduce explicit IDE pin controlLinus Walleij1-0/+35
The IDE pins are managed by the pin controller, if we want to use these, we need to ask the pin controller to explicitly enable them as by default, these pins are used for other business and most users just rely on the SATA bridge.

2017-08-11ata: sata_gemini: Retire custom pin controlLinus Walleij1-34/+0
I added a proper pin control driver for the Gemini SoC, so retire this custom code and rely on the pin controller to set up the pads. The "IOMUX" which is routing signals between the ATA and SATA bridge inside of the chip is not about pin control and remains in place.

2017-08-02ata: sata_gemini: explicitly request exclusive reset controlPhilipp Zabel1-2/+2
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

2017-06-12ata: Add driver for Faraday Technology FTIDE010Linus Walleij1-0/+438
This adds a driver for the Faraday Technology FTIDE010 PATA IP block. When used with the Storlink/Storm/Cortina Systems Gemini SoC, the PATA interface is accompanied by a PATA<->SATA bridge, so while the device appear as a PATA controller, it attaches physically to SATA disks, and also has a designated memory area with registers to set up the bridge. The Gemini SATA bridge is separated into its own driver file to make things modular and make it possible to reuse the PATA driver as stand-alone on other systems than the Gemini. dmesg excerpt from the D-Link DIR-685 storage router: gemini-sata-bridge 46000000.sata: SATA ID 00000e00, PHY ID: 01000100 gemini-sata-bridge 46000000.sata: set up the Gemini IDE/SATA nexus ftide010 63000000.ata: set up Gemini PATA0 ftide010 63000000.ata: device ID 00000500, irq 26, io base 0x63000000 ftide010 63000000.ata: SATA0 (master) start gemini-sata-bridge 46000000.sata: SATA0 PHY ready scsi host0: pata-ftide010 ata1: PATA max UDMA/133 irq 26 ata1.00: ATA-8: INTEL SSDSA2CW120G3, 4PC10302, max UDMA/133 ata1.00: 234441648 sectors, multi 1: LBA48 NCQ (depth 0/32) ata1.00: configured for UDMA/133 scsi 0:0:0:0: Direct-Access ATA INTEL SSDSA2CW12 0302 PQ: 0 ANSI: 5 ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] 234441648 512-byte logical blocks: (120 GB/112 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA ata1.00: Enabling discard_zeroes_data ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] Attached SCSI disk After this I can flawlessly mount and read/write copy etc files from /dev/sda[n].
