2019-05-21	treewide: Add SPDX license identifier for more missed files	Thomas Gleixner	1	-0/+1
	Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-08-27	ata: ftide010: Add a quirk for SQ201	Linus Walleij	1	-10/+17
	The DMA is broken on this specific device for some unknown reason (probably badly designed or plain broken interface electronics) and will only work with PIO. Other users of the same hardware does not have this problem. Add a specific quirk so that this Gemini device gets DMA turned off. Also fix up some code around passing the port information around in probe while we're at it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2017-06-21	ata: ftide010: fix resource printing	Arnd Bergmann	1	-2/+2
	The new driver uses an incorrect format string for resource_size_t: drivers/ata/pata_ftide010.c: In function 'pata_ftide010_probe': drivers/ata/pata_ftide010.c:520:17: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=] The nicest way to print the address is to pretty-print the resource using %pR.

2017-06-12	ata: Add driver for Faraday Technology FTIDE010	Linus Walleij	1	-0/+567
	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].
