Merge tag 'ata-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ata updates from Damien Le Moal:
- Fix OF include file for ata platform drivers (Rob)
- Simplify various ahci, sata and pata platform drivers using the
function devm_platform_ioremap_resource() (Yangtao)
- Cleanup libata time related argument types (e.g. timeouts values)
(Sergey)
- Cleanup libata code around error handling as all ata drivers now
define a error_handler operation (Hannes and Niklas)
- Remove functions intended for libsas that are in fact unused (Niklas)
- Change the remove device callback of platform drivers to a null
function (Uwe)
- Simplify the pata_imx driver using devm_clk_get_enabled() (Li)
- Remove old and uinused remnants of the ide code in arm, parisc,
powerpc, sparc and m68k architectures and associated drivers
(pata_buddha, pata_falcon and pata_gayle) (Geert)
- Add missing MODULE_DESCRIPTION() in the sata_gemini and pata_ftide010
drivers (me)
- Several fixes for the pata_ep93xx and pata_falcon drivers (Nikita,
Michael)
- Add Elkhart Lake AHCI controller support to the ahci driver (Werner)
- Disable NCQ trim on Micron 1100 drives (Pawel)
