libata: fix ata_pio_sector for CONFIG_HIGHMEM

2021-08-12T11:32:26+00:00

[ Upstream commit ecef6a9effe49e8e2635c839020b9833b71e934c ] Data transfers are not required to be block aligned in memory, so they span two pages. Fix this by splitting the call to >sff_data_xfer into two for that case. This has been broken since the initial libata import before the damn of git, but was uncovered by the legacy ide driver removal.

ata: ahci_sunxi: Disable DIPM

2021-07-19T08:04:50+00:00

commit f6bca4d91b2ea052e917cca3f9d866b5cc1d500a upstream. DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

pata_ep93xx: fix deferred probing

pata_octeon_cf: avoid WARN_ON() in ata_host_activate()

2021-07-14T15:06:40+00:00

[ Upstream commit bfc1f378c8953e68ccdbfe0a8c20748427488b80 ] Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler' parameter being non-NULL if the polling mode is selected. Let's only set the pointer to the driver's IRQ handler if platform_get_irq() returns a valid IRQ # -- this should avoid the unnecessary WARN_ON()...

ata: ahci_brcm: Fix use of BCM7216 reset controller

2021-05-03T18:15:04+00:00

This driver may use one of two resets controllers. Keep them in separate variables to keep things simple. The reset controller "rescal" is shared between the AHCI driver and the PCIe driver for the BrcmSTB 7216 chip. Use devm_reset_control_get_optional_shared() to handle this sharing.
